2007WFP gradient banding

[josh6079]

My truck makes a clicking noise, and it has some rust forming on it. Oh, and the paint job isn't exactly the same shade everywhere, etc.

Honestly guys, shut up and play. Put your microscopes back in your pockets, forget what name is on the monitor (since some people don't even want to acknowledge the fact that Dell can do some good things), and just start spending more time doing what you wanted to do with a computer. If you don't like what you have, return it and try another monitor until you do.

I don't want to offend anyone, but dam, everyone agrees that every monitor has its issues. So what is the point in nit picking at every little issue on one monitor if you're going to find another issue in another monitor? IMHO, the Dell is probably the one of the best bangs for the bucks in terms of monitors (The VeiwSonic is probably a little better here though since it is 130~150 dollars cheaper).

 

[oddity]

The issue is glaringly obvious, it's not like we are sitting here going "LOL DELL SUCKS! LETS BASH IT!"

Most of us have noticed it playing games or using apps like photoshop. Many games use gradients. They look awful on this particular monitor. Therefore, it is a defect. So no I for one, will not "shut up and play." We aren't "nit picking at every little issue on one monitor," we are trying to resolve a massive defect that simply should not exist. If you bought a brand new truck, and it ran worse than your old rusty, clicking noise truck, would you be like "yeah ok this is great!" I highly doubt it.

Try being a little less patriotic to Dell (which is what it seems like you're doing ("OMG LOL DELL PWNSZZ YOU GUYS ARE ALL STUPID HAHAHAA")) and try to accept the fact that no, we aren't complaining about a tiny issue that nobody will ever notice but something that sticks out like a sore thumb.

If you'd even bothered to read any of the thread you'd have seen the pictures people have posted from various games, test applications, etc. You'd also notice the fact that almost everyone who has complained about the issue says they LOVE the LCD except for the fact that the gradient banding is so bad.

Having used mine for a few hours last night, so far I agree with his synopsis:

"If in the Desktop Mode as previously stated, there will probably not be any banding noticed in normal usage. I have not noticed any banding in games, videos, or pictures, only gradient tests. Hell, I have some gradient banding on my 37" Sharp Aquos LC-37D6U when I tried the gradient test on it, but never noticed any problems playing games or watching TV and movies on it."

I totally agree with that review - the monitor is awesome (actually I have the L2000c, which has less banding than what is shown in the gradients he posted) in every respect other than DVI banding, which I have yet to really notice in any application (unless it's a sky and I'm looking right at it), and the VGA looks just as good with little or no banding. I agree with xtknight that this banding issue is getting blown out of proportion (I'll take it over backlight bleeding or crappy viewing angles any day) and that most people won't notice it in 99% of what they do. Those that do care can simply switch to VGA without any apparent diminution in other visual quality.

Some people are not "seeing" it in their applications. People gave the same fuss about the backlight bleeding on my monitor, but I have yet to notice it in anything other than a plain black screen. (Gee, I look at that a lot).

I'm not glorifying Dell, just simply saying that they have issues like eveyother monitor. Weird how you jump to me being a patriot to them when I've just given a blunter form of what others have already said. And it does seem like this place bashes Dells more than plastic finds Dolly Parton. I'm just saying that if they like it better than any of their other monitors and don't want to return it to look for another one than keep it. No one here is expecting that Dell is going to fix the problem right away. But if they are really unhappy with it then return it and get a different monitor. If they don't want to get rid of it for another, then shut up and play.

 

[imported_greyhound]

I should clarify that my reference to sky means cloudy or dark skies - I don't have blue banding.

I disagree that the majority of users have reported banding in games, etc. The review in widescreen gaming said exactly the opposite, as did the first L2000c buyer who posted in late march and several others.. If you go back and read the posts - some have noticed DVI banding outside gradient tests but most haven't, though perhaps that is somewhat skewed by L2000c user reports vs. Dell user reports. The banding shown on the widescreenreview forum gradients photo is significantly worse than mine, particularly re blue (I have none) and gray (mine is not as severe).

Again, the VGA option is a legit solution for many (not all). If this monitor with VGA is better than anything else available, do you condemn it just because in theory DVI is preferable?

Fair enough. Anyways, I've always liked Dell, they seem to be one of the better companies out there in the way of pre-built computers (though I build all my PC's myself). Don't get me wrong either, I don't know you at all so I'm not about to start an argument (or at least, carry one on any further than it may have already gone). Personally, yes, I notice the issue and hope it is resolved in the future through a revision. My biggest beef is that, until that happens, if it does, or until I find another monitor to work with I have to go back to a 17" CRT which isn't looking too appealing after using the dell 20" widescreen.

I personally don't see much of a difference in the banding between VGA and DVI.

 

[yacoub]

Bottom line is it's an unacceptable flaw that affects the usefulness of the monitor for anyone viewing photographs or other high-quality images or artwork. This is not simply something relegated to artists but needs to be fixed because it is a flaw that affects EVERYONE in one way or another. I mean unless you think it's acceptable to pay ~$500 for a brand new monitor that looks worse than a five year old monitor...

Some of us don't like being beta testers and feel completely free to voice our opinion. Some of us even feel a bit of obligation to get the word out on defective equipment. Sharing this information is a community service to other early adoptors. This monitor clearly has a defective DVI input. It is even possible that by spreading the word, something might get done to fix it sooner.

If you don't want to hear about it, I guess you will just have to not read threads about something irrellevant to you.

The only person I see completely wasting time on something irrellevant is yourself.

Ah, that explains some of it. On the LG, there is a huge difference in the banding. The grayscale gradient on VGA is very smooth in both linear and circular patterns.

I see your point, however, if your hoping that talking a lot about a problem is going to get it fixed, then you must have missed all of the talk about the 2005's when their backlight bleeding was the rage of conversations related to monitors. Did they get fixed? Sure, when the 2007's came. Therefore, me telling people (like you) to either live with what they have, or get something else is time better spent than talking about a problem that has a low chance of being resolved. Spread the word? Anyone who is smart enough to research something before they buy it will already know from what has already been said. I can't believe this thread is what...11 pages long?!? To me, the options are simple.

Banding in Oblivion, at the horizon:
http://ryannorton.googlepages.com/2007w...ding003.jpg/2007wfpbanding003-full.jpg

Still crappy pictures due to lack of camera skills. This wouldn't bother me if my 2001FP did it too. Dell is sending another monitor, we'll see what happens.

 

[Heartbreaker]

If there weren't threads like this, what would there be to research? Yes I did miss the backlight discussion, since I wasn't looking for a monitor then.

I did encounter this when looking at 2007 stuff:
http://www.hardforum.com/showthread.php?t=1047901

2005 with no backlight problem, so it wasn't a universal problem. And it is a problem that crops up on many LCD not just the Dell. Look at a Dell 2007 vs viewsonic, the viewsonic had backlight bleed.

By contrast this Dell banding issues, is apparently a design defect that all the Dell 2007 panels have, and further it appears practically no other Panels do (to this extent) even 6 bit dithering panels do a better job. There is a serious design defect here that Can probably remidied by changing a chip. The leaky backlight is a fundemental panel issue that is harder to fix.

This thread continues to be a better resource especially when people add game shots of problem, so you can know if it is something that will be a non starter for you, BEFORE you buy it.

Back to your car analogy, this is not like your old truck getting rusty. This is like a new truck that doesn't have a working 2nd gear. Yeah you can still use it, but WTF would you pay full price for it?

I can assure you I did research this product as much as possible at the time - all reviews and write ups were good, some even stated that gradients were smooth. Unfortunately I could not go and see one for myself as there are no Dell kiosks in my area.
If a thread like this one existed a few weeks ago I probably would have recognised that this product may not be suitable for some of the work I intended to do on it.

btw - I hope your truck isn't brand new otherwise I sugest you take it back to the supplier as it obviously has some defects.

 

[josh6079]

I do agree with you guidryp in that this thread does help someone who is looking to buy a new monitor justify which one they might get. However, you're telling me that your going to rely on the mass complaints of users to initiate a recall on the monitors to Dell and have everyone get either refunded or redistributed a new monitor with the fix? Are you kidding me? Listen to the people who've contacted Dell's customer support recently. Yeah, they're top notch.

Research wise, this thread already hits points that other threads do. But if you have recently found yourself with a defected, new monitor that is displeasing you, common sense tells me that your should return it and use the refunded money to get one you like more. Keeping the monitor and talking about it wont get Dell to change anything because they already got your money. Having a mass amount of people return them their monitors and force them to give back profits just might get their attention more.

The more we keep this thread active and on top, the more people check their monitors and return them...

I bet this is resolved in the second batch of the monitors.

 

[spronkey]

No offense josh, but are you a tard or something?

Recalls aren't initiated by people returning monitors - they're initiated by lots of people explicitly telling the company who produced the item that there is a problem.

I'll bet most of the people here who returned their 2007wfp's didn't even make mention to dell about the banding issue, apart from giving them a reason to return it. If Dell's QA missed the banding problems the first time round, they'll test the returned monitors, miss the banding problem again, and give it to somebody else who wanted a replacement.

This was about the first thread on the banding issue around, and I've been following many of them (here, hardforum, widescreengaming, whirlpool, support.dell.com) very closely. It's also the most useful.

Either way, this monitor is FUNDAMENTALLY flawed - colour banding is something that was eliminated with dithering and FRC back when LCD's were very much a fledgeling technology. Given that there is also an issue with blurry images wiht the same DVI input, suffice to say that this monitor has issues.

If it can't display a simple test like a gradient properly (and let me re-iterate, this is a FUNDAMENTALLY SIMPLE TEST), it has severe issues.

It also rules this monitor out for ANY kind of colour-accurate work whatsoever; yet it's an S-IPS panel, which almost anyone looking for colour-accuracy will go for.

Dell don't CARE about losing profits on there. Not everyone will return their moniotrs, and even if they do, it's not exactly lost profit to dell, because they can fix them and use them as replacement monitors for other people.

We need to get dell to recognise this as an issue, and do something about it.


For the record, my 2005fpw had no backlight leakage whatsoever.

 

[cmge]

i just got my 2007wfp as well im still a little confused with the banding issue... is this good or bad?... i compared my dell 2007wfp with my friends samsung 204B

DELL 2007WFP native resolution 32bit colour
http://www.fileh.com/cmge/dell2007wfpgradient.jpg

SAMSUNG 204B native resolution 32bit colour
http://www.fileh.com/cmge/samsung204bgradient.jpg

if im not mistaken they look ALOT alike... and from the look sof it the samsung is worse.. having the images in JPEG kinda ruins the clarity

Wow, you're the first person to ask that in an unoffensive way.:thumbsup:

Recalls aren't initiated by people returning monitors - they're initiated by lots of people explicitly telling the company who produced the item that there is a problem.

Really, try telling Dell that you're not happy with your product...and then keep it. I'm sure their five-star, caring and knowledgable customer service will be sure to forward your complaint.

I'll bet most of the people here who returned their 2007wfp's didn't even make mention to dell about the banding issue, apart from giving them a reason to return it. (This sentence doesn't even makes sense, people who would be returning the monitors would be doing it for that very reason.) If Dell's QA missed the banding problems the first time round, they'll test the returned monitors, miss the banding problem again, and give it to somebody else who wanted a replacement.

Exactly, so that is why I'm telling people to either get a new one or keep what they have. Dell is not going to fix the problem if people keep asking for replacements.

This was about the first thread on the banding issue around, and I've been following many of them (here, hardforum, widescreengaming, whirlpool, support.dell.com) very closely. It's also the most useful.

I've already agreed that this thread helps someone see if they want the new dell monitors.

Either way, this monitor is FUNDAMENTALLY flawed - colour banding is something that was eliminated with dithering and FRC back when LCD's were very much a fledgeling technology.

Yes, these issues are being discussed here. Telling Dell directly as you give them back their defective product in exchange for the money you once gave them helps relay the issues to them more effectively.

Dell don't CARE about losing profits on there. Not everyone will return their moniotrs, and even if they do, it's not exactly lost profit to dell, because they can fix them and use them as replacement monitors for other people.

Same thing as you said before:

If Dell's QA missed the banding problems the first time round, they'll test the returned monitors, miss the banding problem again, and give it to somebody else who wanted a replacement.

We need to get dell to recognise this as an issue, and do something about it.

EXACTLY! And how would your non-retarded, esteamed and ingenius self go about doing that more effectively than simply talking about it on a third source service?

For the record, my 2005fpw had no backlight leakage whatsoever.

 

[spronkey]

First, cmge - are those actual photos? (if so, what on earth amazing camera do you have !?!??!?!) If so, that looks like some severe banding. The dell is definitely worse, but the samsung doesn't seem to be doing very well either :S If not you'll need to take photos of the screen and not screenshots in your operating system.

Josh, the point is this: we might be talking about it here - but there's also a large thread over at dell's support forums. That's how we're initiating action, and it's a better way than to send monitors back to Dell. The point is, we want these monitors, but we want them WITHOUT the MANUFACTURING error.

I doubt whether the number of people noticing this error is that large in the first place (lets face it, a lot of people will buy one of these and think banding is perfectly normal), and furthermore I doubt whether the number of people who would actually return their monitor (and go through the subsequent hassles of getting refunded) is that large either. It's likely that even with this error, unless we explicitly make it known to Dell that this is a severe error by submitting enough complaints that they take notice (and hopefully, action) they will likely shrug it off as an acceptable return rate.

That leaves discussion with Dell support as the best way to get our problem fixed.

This thread is more about finding the problem, and seeing if anyone ISN'T affected, in which case we'll want to know everything about their particular setup.

Since I hadn't seen any pics I thought they were complaining about the everyday anomalies you'd get on any LCD but these seem a lot worse (from what I'm hearing). Well, to be honest, I'm still confused if it is worse or not, But I have a cheaper LCD that doesn't have nearly that amount of problem as seen in the photos and I think Dell should get it fixed on their ****7 series. I just feel anyone who doesn't own one shouldn't make claims about how bad it is.

What's interesting is it appears much worse on some peoples' than others judging from those screenshots. And we need (more) things to compare it to, but until then I'll remain sort of neutral on this. Now I'm surprised to see the Samsung TN does it that bad, if that is indeed a photo of it. Maybe the PVA/MVA panels are just exceptionally immune to this but it's nothing like that on my 6-bit VP930b MVA, which is practically as big a dot pitch as they come, in the desktop sector.

What seems most worrying is the liney patterns appearing within places where they shouldn't be.

Try setting the contrast to 80% and then going in the color components and setting them to 25% each to see if you get a better result than setting contrast to ~50% and color components to ~50%. Sometimes there are just weird combos like this, and on many screens, contrast above 80% introduces brightness instability.

Edit: changed this post around a lot.

We want the same thing.

I doubt whether the number of people noticing this error is that large in the first place

Some beg to differ. In fact, have we yet seen another source say that they don't have any banding? It is a problem/defect and a large one. However, there are a lot of people who don't notice it when doing the things that they mostly do, just like there are a lot of people who do notice it.

(lets face it, a lot of people will buy one of these and think banding is perfectly normal)

Are you retarded? If that were the case then we wouldn't have so many people saying, "Yeah, I see it". I think it is more a matter of, "Yeah, I see it, but only when doing (xyz)". There are a lot of people who barely notice it, none who don't have it happen.

and furthermore I doubt whether the number of people who would actually return their monitor (and go through the subsequent hassles of getting refunded) is that large either. It's likely that even with this error, unless we explicitly make it known to Dell that this is a severe error by submitting enough complaints that they take notice (and hopefully, action) they will likely shrug it off as an acceptable return rate.

I'm not saying that that isn't a way of going about doing it. It's just it doesn't get there attention as much. Fact is, those who do muscle up the crap that it probably would take to return it are probably also already contributing their share of opinion on the Dell discussion. You can't tell me that a company losing its money and getting complaints isn't as good as just complaining.

This thread is more about finding the problem, and seeing if anyone ISN'T affected, in which case we'll want to know everything about their particular setup.

I agree.

So far, anyone I've seen that has replied saying they're not seeing a problem, or in my case only very faint banding on the test patterns (which is identical to my 1907FP at work), is either a) believed to be half-blind and incapable of seeing banding issues, b) disbelieved and told their banding issues are actually severe, or c) a and b.

I am not trivializing the fact that there does seem to be a problem, particularly in games, I've seen the WoW banding in pictures posted here and elsewhere and it looks awful. The amount of discussion threads on this topic points to some kind of issue. I find it a huge leap of faith, however, to say that "all" panels have this problem based on a small amount of data. There have been several posts in this thread, as well as elsewhere and in the reviews I've read, that have stated no abnormal problems with banding. You yourself say that you have a 2005FPW without backlight bleed, and we all know that was a problem that affected many but apparently, in your case, not "all" 2005s.

I think it'd be great to see more data on setups and what people have tried that does or does not reveal banding. For my part, I know I've been reading these threads and trying to do what others have done to see if I can reproduce the problem. Any further inputs I'm glad to try.

Panel: 2007WFP, Made in Mexico, factory adjustments except phase changed from 73 to 69 (DisplayMate test had much better results at this level, no 'rolling' of pixels).

Setup 1: DVI, XFX 6800 video card, 1680x1050 resolution, 60 Hz, Desktop Mode
No noticeable banding on desktop, webpages, etc. Gradient Banding chart looks good overall, can see faint banding on greens, but very similar to my 1907FP at work. DVD playback great, faint sky blotchiness noticed on grays over blacks (LOTR: ROTK, Gandalf and Pippen on the balcony, watching the clouds coming forth from Mordor).
Games:
Neverwinter Nights - no issues noticed. (Same res, 2xQ AA)
Guild Wars - no issues noticed, looks great. I stared at the sky for minutes at a time, smooth transitions everywhere.

Setup 2: VGA, Intel integrated graphics, 1680x1050 resolution, 60 Hz, Desktop Mode
Not much time spent in this configuration, but no issues noticed.

Skeptism happens because I believe in the preponderance of evidence. I have watched this in Hardforums, Dell support forums, widegaming forums and here. There have been several series of photos that show the problem including comparison with other monitors and and DVI/RGB comparisons. Every instance backs up the universality of the issue.

Also because I believe in the variability of observational awareness. One guy on one of these threads always ran his computers in 16bit mode because it was faster and he never noticed a difference!

I have seen at least two people so far say their unit is perfect only to come back a few posts later, completely changing their tune after they have done adequate testing. I have seen the images from one person who claimed his had non existent banding, but his shot was full of banding. Show me a camera screenshot from gradlin:
http://xtknight.atothosting.com/tools/gradlin-v0.2-fs.exe

Preferably with both RGB and DVI inputs. Then maybe I will believe you do have that one magical monitor. For myself right now, the non banding 2007 is an extraordinary claim. Like Carl Sagan, I beleive that extraordinary claims requires extraordinary evidence.

It is handy if we all use the same test for comparison. I don't pay much attention to the game test pro or con. Harder to notice, harder to quanitfy and harder to verify it is not simply a source issue.

My Dell 2007fp (reputedly has same problem) should be here next week and I will post my own results taken in RAW mode with my camera and saved as PNG, with no lossy processing anywhere. I will shoot all test shots using both DVI/RGB input modes. I did test this on my Dell 2405 and there was no banding, my CRT shows no banding.

I'm waiting for two of these (2007wfp) to arrive, after having sent back the one 2005fpw i had (starting to regret that - i wanted two of them, but dell didn't have any left ), and I have a number of questions for 2007wfp owners.

Firstly, I've created a test image in PNG and TIFF forms (to ensure that PNG and it's own colour profiles aren't the problem, make sure they both display the same). The URLs:
TIF: http://www.spronkware.com/spronkey/sdc-testchart-gradientbandi.tif
PNG: http://www.spronkware.com/spronkey/sdc-testchart-gradientbandi.png

Secondly, could you please put your monitors into DESKTOP mode.

Thirdly, could you ensure that NO OTHER INPUTS are connected to your LCD at the time of testing.

(this is my attempt at a controlled experiment)

Could a few please post some photos of their 2007wfp's displaying this test image in the following configurations (all in desktop mode):

- VGA mode, Default colour settings, Default contrast/brightness
- VGA mode, Lowered colour settings (30, 30, 30), Default contrast/brightness
- VGA mode, Lowered colour settings, Lowered contrast/brightness (30, 30)
- VGA mode, Lowered colour settings, Lowered contrast/brightness (30, 30)

- DVI mode, Default colour settings, Default brightness
- DVI mode, Lowered colour settings (30, 30, 30), Default brightness
- DVI mode, Lowered colour settings (30, 30, 30), Lowered brightness (30)
- DVI mode, Default colour settings, Lowered brightness (30)

With the test images above, you should see smooth gradients with dither on both horizontal and vertical, followed by smooth gradients (which are mapped at one 1px line per colour, unlike some of the test gradients around). The lower saturation gradients should also be smooth with no banding.

The six diagonal gradient squares should be smooth, the top 3 use dithering, the bottom three use flat lines.

The RGB squares should also be smooth.

Hopefully the following tests above will provide some sort of insight into where the problem lies. I'm thinking the digital logic chips inside the monitor might be clipping certain signals because they are slightly too strong, or some other strange phenomenon.

Anyhow, photos of these test images in the 8 above modes would be appreciated, and hopefully should prove helpful.

Very awesome images! Perfect for testing banding without needing to rely on some program to run. My 1600sw shows no banding at all, so i'm shocked that a new monitor like the 2007 would have it.

First, cmge - are those actual photos? (if so, what on earth amazing camera do you have !?!??!?!) If so, that looks like some severe banding. The dell is definitely worse, but the samsung doesn't seem to be doing very well either :S If not you'll need to take photos of the screen and not screenshots in your operating system.

IMHO your banding isn't that severe, cmge; just a little bit in the green row.
