They belong right under the NEC 20WMGX2. That's the same panel the NEC uses, essentially, with a hard anti-glare coating instead of a glossy one.

http://store.apple.com/1-800-M...01B&nclm=AppleDisplays

I'll be using it for alot of games, and also for photoshop. I don't need an industrial grade color correct lcd, I just need one that can do everything pretty well.

I have been looking at some of your recommended lcd's but they are just too ugly for me, this is about the only decent looking monitor around. The whole things aluminum, crazy!

It's one of the best 20" LCDs out there (it's S-IPS and should still be to this day). However, I recall that you could only access the controls (easily) on a Mac. That may have changed, and there may be some other ways to control it via a PC (via DDC/CI command interface). You'd have to google for more info on that. It's a great monitor though.

BTW did you guys who got your 2407-HC have a DVI monitor come with it? It's not listed in my order so I'm thinking I need to get a cable beforehand.

It comes with a DVI cable.

Xtknight,
The picture does look like those in that thread, this is my first LCD so i'm not keen on specifics, but it is bright, it is actually easier to read these forums vs my old CRT, not sure if size or just different rez is the culprit. The 3 settings in OSD for Desktop/Multimedia/gaming mode places a big part in this though, no telling what mode they had it set in for those screenshots they did.

Btw the newest beta drivers Enable DVI scaling, it was disabled for a long time in Vista for those interested, they are the 162.22.

Question: In the Nvidia control panel what setting should I use for scaling? These are the options..
Use NVIDIA scaling
Use NVIDIA scaling with fixed-aspect ration
Use my DIsplays's Built-in scaling
No Not scale

Ok there are some things I don't understand with this monitor. What is PC Mode and Mac Mode in color settings on OCD? What should it be? The default is Mac Mode

Ah well, I managed to get time to make a trip to a local store to check out some LCD monitors and ended up walking out with a Samsung 931BW. Seeing it side by side with the HP w2207 (which is what I had thought I would be leaving with) I honestly couldn't tell any difference in the quality of their pictures. The samsung they had on display was labelled as an A panel (is the lottery not just limited to 206/226bw's?) but it looked great and they actually had it hooked up via the analogue connector so I somehow doubt they had spent any time calibrating it. One thing that shocked me was just how big the w2207's footprint was. I don't recall seeing it mentioned in any of the reviews I'd seen but it would have ended up taking up just as much space on my desk as my CRT did (one of my main reasons for getting an LCD was to save space).

Hmm, I wasn't aware of that. I see it mentioned other places though so I'll add that to the notes. Thanks (at least you didn't order it and then find that out later).

All in all, I couldn't justify the extra £70 being asked for the w2207, and they scuppered any chance of me buying the w1907 by it only having an analogue connector.

Hmm, this spec shows that it has DVI+VGA. http://www.compusa.com/product...5486&pfp=XSELLPRODAUTO

The 931bw I bought is an unlabelled panel (but in that hidden system menu it shows as 'M-MD19W0CLa-1000'). I can't pick out any dead pixels. In terms of backlight bleed there is a centralized band along the top, perhaps a third of the length of the panel, which is quite noticeable when watching a movie at night.

Yeah, 19" widescreens tend to be bad with backlight bleeding.

The blacks aren't really all that black I have to say, but the colours seem quite good actually (no noticeable bias towards one in particular). Admittedly I've yet to do any calibrating, but the picture out of the box hasn't disappointed. I've also seen no ghosting at all playing a variety of different games.

...they also tend to be very fast and have great contrast, especially the Samsungs, so your experience is consistent with that. Thanks for the overview.

I bet they will use "S" to start with, and if they run out, they will outsource. They said that sinec the 226CW won't be nearly as popular, they won't have a problem supplying only "S" panels. You probably recall the last incident however where they said something...

xtknight, how od you think the CW would compare to the LG L226WT? Is the L227WT LG's new monitor with the 92% HC?

Yes the L227WT according to BernardP's info is a wide gamut L226WT. The CW would provide richer, more natural colors than the L226WT with a higher contrast (if it has an S panel). Compared to LG's L227WT, it might still be slightly better but I'm less sure about that comparison. Samsung's 226BW "S" panel is said to be better than the L226WT but I can't recommend it for obvious reasons.

oh, TN.

But still it looks good for people who would be getting a non-glossy TN (e.g. Samsung 245BW) instead. Good find, it's always nice to have more news these days in the thread also.

In a short answer: no. Your cheapest option is the Samsung XL20 at $2000 USD, sadly. If that's not expensive enough for you then you have some other options like the $6000 reference NEC.

Have you previously owned an LCD (or even CRT)? If so, describe if/how the HC has a more natural picture.

Mac Mode AFAIK uses a gamma of 1.8 (old Macs) and PC Mode is for sRGB (approx 2.2) gamma. I think even new Macs use the sRGB color space now, or so I've read. I'm guessing you have a PC, so leave it at PC Mode. If you have Mac OSX I'd also leave it at PC Mode (unless it appears obviously wrong), and OS9 or lower, use Mac Mode.

Interesting, I hope all the settings look more natural than the vanilla 2407...

See the scaling ("Native Resolution") section in the OP. The best depends on your monitor and video card.

I'm sure I remember reading something about a European tax which only applies when a digital connector is present (it gets counted as a TV or something like that), so maybe that is the culprit.

Ah, yes, that's true. That is the w1907v model actually, the v probably meaning value (doesn't have DVI input).

I've been watching this thread for a while now as I try to decide what LCD to buy. It's *extremely* useful, everyone should give the first post a read before buying anything!

I wanted to ask if there are no 22"+ monitors that would be good for prosumer photo editing. I see there's the 21" Samsung SyncMaster 215TW listed under the recommendations but nothing larger. Is this because larger LCDs are all TN types? I am tempted by the Dell 2407wfp-hc (I'm getting a new Dell desktop) but does a wide gamut alone make this good for photoediting, it's a TN panel isn't it? I know it's too early for full reviews but I don't see the reason for wide gamut is it's not to appeal to designers/photographers. I'm not a pro photographer and most of the work I do is web-based but I'd like a monitor which will help me rather than hinder when it comes to producing work for print.

My laptop has a 1920x1200 res and I'd like an LCD that matches that, just for the sake of synchronicity, and I could go up to $800CAN, which is the price of the Dell HC. However, if a 21" Samsung is going to be the best buy for photo editing I would go with that.

Thanks.

Yikes. I was hoping that since so many notebooks are adding LED backlit displays, we'd be seeing more on the desktop front.

I guess we still have to wait a while.

Well this is my first LCD - I don't really know what to compare it against. Watching some video content, there seems to be more noticeable banding, though I'm not sure if that's just compression becoming a lot more obvious now I have a bigger monitor. I watched downloaded tv shows and anime. Unfortunately have no HD content at all, and haven't found the time to view a DVD yet.

The 2407WFP-HC is presumably an A-MVA panel from AU Optronics, until proven otherwise. It is definitely NOT a TN panel. High-quality panel in a well-built monitor. As for the price, patience is a virtue with Dell. As a fellow Canadian, I have been watching the price of the 2407 closely, and it has gone all the way down to $649 on a couple of occasions. I think that if you are ready to wait at most a couple of months, you will be able to catch it for not more than that...maybe less considering that the canadian dollar is surging at record highs.

This ad page is disapointing as it only talks about the stand and bezel design. Not a word about wider-gamut color or glossy screen. In fact, pictures of the monitor seem to show a standard anti-glare screen. So it seems to be a 226BW in a different wrapping.

Here is a link to a chinese-language review of the 2232GW It can be translated with Google language Tools. The schematics explaining the glossy panel finish is clearly visible.

Could it be that the North American model doesn't have the glossy panel?

Thanks, I realised it can't be a TN panel after posting by looking at the viewing angles. The price has dropped to $699 right now, I might jump on that. I can't wait very long because I need something to go with my new desktop, I've only been using laptops for the past few years and this will be my first LCD monitor.

I just want to get some indication of whether this is a good choice for photo editing and whether they've fixed the 2407 issues like banding, though it doesn't sound like it from the post above yours. I'm wondering why no monitors over 21" are in the photo editing recommendations in the first post, if there's something fundamental about large LCDs that makes them unsuitable.

I believe the MagicClear coating mentioned on the ad page is really the glossy panel. I don't think there would be a point in releasing it otherwise but who knows...it still looks like a 72% monitor.

Not all larger LCDs are TNs, but all 22"s are. Actually most over 22" are non-TN types like S-PVA, P-MVA, and S-IPS.

I am tempted by the Dell 2407wfp-hc (I'm getting a new Dell desktop) but does a wide gamut alone make this good for photoediting, it's a TN panel isn't it?

It's hard to say if the wide gamut makes it better for photo editing, but I'd say no, unless you use the Adobe RGB space. The 72% gamut, otherwise known as sRGB, is the color space used in probably 97% of photos and cameras. If you're using Adobe RGB, you'd know it, and I doubt you are. Therefore, a 72% gamut monitor can provide more accuracy for the gamut it does cover. A 92% one would have adjacent tones spaced farther out so it would be unable to provide the accuracy a 72% can for its native 72% space.

I know it's too early for full reviews but I don't see the reason for wide gamut is it's not to appeal to designers/photographers. I'm not a pro photographer and most of the work I do is web-based but I'd like a monitor which will help me rather than hinder when it comes to producing work for print.

I really don't know how print factors into this, but if I had to guess the 72% would still be better if it's sRGB.

Wide gamut appeals to Adobe RGB-space photographers and everyone else except sRGB photo editors and desktop publishers, pretty much. It provides a more natural image since the backlight's white is more..white. This is explained in the Guide.

My laptop has a 1920x1200 res and I'd like an LCD that matches that, just for the sake of synchronicity, and I could go up to $800CAN, which is the price of the Dell HC. However, if a 21" Samsung is going to be the best buy for photo editing I would go with that.

Thanks.

Go for the Samsung 215TW or Dell 2407WFP (non-HC), whichever is cheaper there, or whichever size you prefer. They're both great, really. There's also the BenQ FP241W which has a better response time and pretty much the same colors with higher contrast ability.

You know, to tell you the truth, I don't really know either. I should have a 24" there. It would probably be the Dell 2407, as it has the most accurate colors after calibration (and roughly the same accuracy before calib. as the BenQ). The 24"s often have great color characteristics, actually. I guess it just didn't pop into my mind when I was listing the recommendations for that section.

I thought they fixed the banding issues long ago. It's going for a great price, too. It will be listed in the Prosumer Photo Editing section now. Ditto for Desktop Publishing since it perfectly matches the sRGB space. Clearly I have a few size gaps to fill.

Indeed. Wide gamut monitors are not able to produce all the intermediate tones conventional sRGB ones are. So everything is going to show up more, including flaws. Sort of like an antenna amplifier in a way that it also amplifies noise unless you tune it right. Make sure you're in desktop image mode, though.

Few notes on a major edit: Looks like all LP2065s use AMVA panels now (from what I've read, all from February are the AUO panels). So it has been removed from all of the recommendations, regrettably. I'm not going to recommend a panel that hasn't been tested. I'm also not very inclined to recommend a monitor that is known to use different panels. Also, the 2407WFP was added to the Prosumer Photo Editing and Desktop Publishing recommendations. Rest of changes are in change log.

The number of quality 20" 4:3 monitors is really shrinking, but I'll see if I can scout out anything else remotely suitable. I'm quite restrictive on what I recommend in Photo and DTP so that number of total recommended LCDs is also plummeting. Hopefully with the advent of LED backlight and wide gamut LCDs that will change (not that the wide gamut ones are that suitable for photo editing anyway). I don't expect affordable LED backlight LCDs to show up for at least 1.5 yrs from now.

The 20WMGX2 is still the best IPS-based panel around, but it is an AS-IPS so you get more banding and the glossy panel that not everybody likes. That's why I'm hoping a few other standard anti-glare S-IPS panels will stick around. The 20WMGX2 can scale down with brightness although its black level then becomes a little lackluster. Other lower-brightness S-IPS panels do a little better in this category as well. Of course, the 20WMGX2 still knocks pretty much everything else away short of those aforementioned "darker" S-IPS panels for certain purposes.

I don't expect to take the proverbial crown off the 20WMGX2 for quite awhile. The 24WMGX3 is coming soon, which uses an S-PVA panel. I'm hearing Sept. 2007, maybe later.

The LCD2490WUXi should probably be recommended soon also, but I wish there were more reviews of it. I will probably wait until then to see if it's truly that much better than the Dell 2407WFP I got up there already.

Let me see if I can change your mind on wide gamut LCD as I have been thinking about it for a while. First, as you pointed out, each color channel's 8-bits are being stretched to cover 92% color space from 72%, which means 5 neighboring colors in 72% gamut will only have 4 values in HC. Can human eyes detect the change? See for yourself:

Red 255 254 253 252 251

The top half of the image contains 5 red patches, 50x50 pixels, of RGB values (255,0,0) through (251,0,0). I can't see the border between them, much less any banding effect on my 8-bit LCD or CRT. I can't even tell which edge (left or right) has (255,0,0). The bottom half of the image contains 4 red patches, with (253,0,0) removed. Again, my eyes don't notice the change. The original 8-bits, which is 256 values, in 72% gamut will have 200 values in 92% gamut, which is plenty. Most human eyes are not capable of detecting the change.

Ok, so what good is 92% gamut when most camera and printers are 72% gamut? Well, the same image will look better on a 92% gamut LCD, even if the original colors are stretched to display in the wider color space. Human eyes perceive color in "relative" terms, i.e. in relation to adjacent colors in the image. Thus the image won't look weird, like false colors. Instead, the green (such as grass or trees) and blue (sky or water) will "pop out" in a good way, by looking more natural and vivid. As wide gamut LCDs become the standard, future cameras and printers will catch up.

Off topice... 6-bit LCDs only have 64 values per color channel. Human eyes *CAN* tell the difference when 256 values (8-bits) are aggregated into 64 values. For photo editing on the HC LCDs, I would set Photoshop to aRGB working space with 16-bits per channel, then save a sRBG copy for sending it elsewhere. Photoshop could also down-convert aRGB images on a non-HC monitor / LCD system as necessary.

About 22" TN's with 92% color gamut, I think they will be an improvement, but they will have the same problems as current 22" TN's. Since 22" LCDs are aimed at general office use and gaming, HC is still good - provided that they don't cost too much more.

xtknight, I was just wondering where you thought Eizo's new s2031w would fit in? Here's its product page: http://www.eizo.com/products/lcd/s2031w/index.asp

And here is a specifications comparison between it and the NEC LCD20WGX2(pro) over at Prad.de. I only chose the NEC because both panels are in roughly the same price range (in Europe).

I've not seen any mention before of a 20" widescreen monitor utilising an S-PVA panel so that alone makes it fairly 'special'.

By the way, great work on your guide (it seems to get better every time I have a look at it)! The amount of info you've manage to compile into that one post is just staggering.

edit - You know I wish more manufacturers would be upfront about what panel technology they have used, instead of having to guess it from viewing angles and response times etc. When you go to the NEC/Viewsonic pages they always tell you, but with others (Samsung, LG, Philips) it's like drawing blood from a stone when trying to find it out. Admittedly it backfires a little in cases such as Acer trying to assert that their al2051w is actually a TN panel not the P-MVA everyone knows it to be, but still, customers welcome openness.

Instead, the green (such as grass or trees) and blue (sky or water) will "pop out" in a good way, by looking more natural and vivid. As wide gamut LCDs become the standard, future cameras and printers will catch up.

Off topice... 6-bit LCDs only have 64 values per color channel. Human eyes *CAN* tell the difference when 256 values (8-bits) are aggregated into 64 values. For photo editing on the HC LCDs, I would set Photoshop to aRGB working space with 16-bits per channel, then save a sRBG copy for sending it elsewhere. Photoshop could also down-convert aRGB images on a non-HC monitor / LCD system as necessary.

I'm just not sure the above is an accurate test if you're viewing it on a 72% gamut.

Samsung 940BF (72%, Samsung TN) calibration report

Samsung 931C (97%, Samsung TN) calibration report

While the end results on the 931C aren't terrible, they're significantly worse for the colors. I believe that deltaE of 2 is the borderline of where the human eyes can perceive a difference, and the 931C goes multitudes above that.

Now, the 3007WFP is another interesting test case. It has hardly any difference and the HC model appears to be perfectly acceptable despite its wider gamut.

DigitalVersus - 3007WFP vs 3007WFP-HC

So, it may depend a lot on the manufacturer. When you put one high quality IPS against another, the HC appears to be doing just fine.

But then the question comes, what about proofs? If most people have 72% monitors the image is going to look quite different than it does on yours (although 72% TN vs 72% CRT is hard enough to coordinate,) If those colors appear to be about as accurate, is there even any difference in the picture? (the deltaE difference between the two is often less than 0.50, undetectable) Perhaps they used poor testing points that didn't show the 92%'s flaws? As it stands I would really like to hear more thoughts on it before I start recommending 92-97% gamut monitors. But I'm definitely considering it given the 3007WFP's results. It's probably going to end up being a case-by-case basis. That said, a healthy dose of skepticism has saved me numerous times.

Besides, you may need a new expensive colorimeter to calibrate 92% monitors as well.

I have nothing against HC monitors. In fact, the next monitor on my wish list is a 2407WFP-HC.

Let me see if I can change your mind on wide gamut LCD as I have been thinking about it for a while. First, as you pointed out, each color channel's 8-bits are being stretched to cover 92% color space from 72%, which means 5 neighboring colors in 72% gamut will only have 4 values in HC. Can human eyes detect the change? See for yourself:

Red 255 254 253 252 251

The top half of the image contains 5 red patches, 50x50 pixels, of RGB values (255,0,0) through (251,0,0). I can't see the border between them, much less any banding effect on my 8-bit LCD or CRT. I can't even tell which edge (left or right) has (255,0,0). The bottom half of the image contains 4 red patches, with (253,0,0) removed. Again, my eyes don't notice the change. The original 8-bits, which is 256 values, in 72% gamut will have 200 values in 92% gamut, which is plenty. Most human eyes are not capable of detecting the change.
Albeit mostly academic, there's a problem with your test image: the conversion to JPEG made a mess of the color values - both the top and bottom actually only have three main shades now, and most of them aren't pure red. There's also the fact that most LCDs have trouble differentiating between color levels at the ends of the scale; it may be a better idea to choose five middle levels.

I have to admit that I can't tell the difference even on a proper (not compressed) image, and even on middle levels, but that changes if we switch to green instead of red - the human eye is more sensitive to green light. In that case, I can actually make out the different rectangles, and also tell which end is darker. Again, I have to admit you have to be looking for those differences to find them - they're far from obvious. But then again, I'm not a professional in this area by any stretch of the imagination; things might look quite different for somebody that does pro image editing all day long.

Ok, so what good is 92% gamut when most camera and printers are 72% gamut? Well, the same image will look better on a 92% gamut LCD, even if the original colors are stretched to display in the wider color space. Human eyes perceive color in "relative" terms, i.e. in relation to adjacent colors in the image. Thus the image won't look weird, like false colors. Instead, the green (such as grass or trees) and blue (sky or water) will "pop out" in a good way, by looking more natural and vivid. As wide gamut LCDs become the standard, future cameras and printers will catch up.
I don't think anybody disputes the fact that the colors will look more vivid on a 92% gamut display. The problem is that, when you're doing pro image editing, you're interested in seeing the image as closely as possible to how it will look on the other relevant output devices. If the gamut you're working with is so widely different from those of the other devices that will be used to render the image, you're only making things look good for yourself, but not for your viewers (or customers).
