Got my 2007FP

[JMWarren]

I've got one dead pixel but no back light leakage. Color is good.

My big grip is with Grey scale gradients.

There is definatly some banding in them.

Any Ideas?

What do you mean by banding? Is there discoloration or duplicates of one color within the grayscale? Usually 'grayscale problems' can be fixed with some minor gamma tweaking (using non-linear gamma, advanced mode in NVIDIA Color Correction panel). That and a combination of brightness/contrast adjustment on the monitor, or R/G/B component adjustment if needed. Once you get a good, linear-looking grayscale, every image will appear with more detail than before with a splotchy, redundant-looking grayscale.

It's normal to have these problems at default settings and this is why calibration software is so popular for professionals. Unfortunately a lot of reviewers find that concept hard to grasp and go off of what it looked like when it came in the box and declare it to have banding problems.

You are obligated to take :camera:s!

Not exactly sure why the banding only occurs with greys. Do you notice it with any other color?

 

[JMWarren]

Anyone know a good peice of software to generate test gradients? I've been using photoshop but am worried that somthing funny may be going on...

The banding looks like destincitve bands of grey... Not smooth like it is on my CRT.

JMWarren: Here's a program I had made just for this purpose. http://xtknight.atothosting.com/tools/gradlin-v0.2.exe

It shows 17 steps in the first row and 256 steps in the second row, and so on, for red, green, blue, and gray respectively. The first square in each 17-step pattern should be black. The 17-step pattern isn't supposed to be smooth but the 256-step one is. And, nothing in the bottom grayscale should look like anything except gray, no red tints to it. You can adjust how this looks with Color Correction in the NVIDIA control panel, advanced mode, and adjusting it until it looks perfect. Some brightness/contrast adjustment (on monitor, not NVIDIA control panel) may also be neccesary. You should be able to see the whole scale with only the first square on the scale being full black and the last square being full white or (full red,green,blue).

I've posted pics of the problem. xtKnight, anyway to get that program to run full screen?

This one should work in fullscreen. Press ESC to end the program. http://xtknight.atothosting.com/tools/gradlin-v0.2-fs.exe

Thanks, I'll throw the Spyder on it from work when I get a chance (in a month or so). I installed the ICC profile and it seemed to help. I'm not sure why it would.....

Can you verify the screen type. Is this definitely an IPS screen? Can you turn down the backlight so it doesn't burn like the sun. I got rid of a 2405 because of display brightness/harshness even with the backlight on lowest and view angles drove me nuts. If this really is an IPS screen I might give it a try. I wish Dell would stop cranking the brightness, people have said they couldn't calibrate properly, because of the extreme brightness of the 2405.

When you did this on the 2405/2001fp you get the service menu, which IIRC displays the panel manufacturer.

1) Hold menu and '+' buttons (3rd and 5th buttons from left) while powering on the unit.
2) Press menu button (5th button from left) and select "Factory Reset"
3) Select "Factory" at the bottom of the menu

Bump for an eagerly awaiting little boy who really wants to upgrade his 15" lcd.

Yes, this is indeed a S-IPS panel made by LG-Philips.

I have the monitor right now and the model panel is LPL UXGA LTM201U05

And yes this thing is super bright out of the box as well, I had to turn down the brightness right off the bat.

 

[Shortass]

Have either of you played games? How's ghosting? I know they reduced the response time by 4ms, is it noticable?

 

[Heartbreaker]

Great stuff. Can it get reasonably not bright when you turn it down? I found on the 2405 it was still too bright even at minimum.

Here is a link to TFTtest that has some clean gradient tests that I am curious about now that I see the other guy seemed to be having some problems.

[imported_mclaren128]

The only game I have tried was CS Source, and I do not detect any ghosting at all. I had a 2405pfw before and I thought that looked better.

Yes you can get it to a reasonable brightness level, I set it to 36 right now and it's fine I think. This is not like the 2405 where it was like staring at the sun even at zero brightness. I had to use my ati software to lower the brightness an additional few points.

 

[Heartbreaker]

You had a 2405 too? Why don't you have it anymore. I got ride of mine because of viewing angle wierdness and extreme brightness, so if this has better brightness control and less viewing angle issues, I may get it. Just need another sale...

So you are also saying the 2405 looked better gaming? Anything you can put your finger on?

 

[imported_mclaren128]

I returned the 2405 because I kept getting dead pixels in the middle of the screen, and I returned it like 3 times before I finally just asked for money back. I just though CS looked better on the 2405, maybe it was the 19x12 resoluation compared to 16x12, can't put my finger on it. Also the S-IPS panel has this glossy/sparkly film on the panel, so that takes getting use to. One thing for sure is that the viewing angles are much better on this than the 2405. I just got this last week during the Dell Sale in Canada, so I'm still undecided if i want to keep this, I may have to go back to my p95f+ crt in the mean time.

 

[Heartbreaker]

I'll probably wait for another sale. How much was it on sale? I am in Canada too. I got my 2405 during the 12 days of Dell. I didn't return because there was nothing wrong other than the insane brightness and viewing angles. Which are apparently normal for a 2405.There policy stated 15% restock if there were no actual problems with the product so I sold it for a loss. :-( I suppose I could have fought it.

Are you having gradient problems like the other guy? Anything in the tfttest program above, the top line has 4 different gradient tests.


Anyway guys let me know how it turns out and if you keep your monitors. I need something new. My tired 19" crt is seeming real weak after getting rid of the 2405.

Get NEC you won't have this problem.. both xknights programs display perfectly linear on mine.

Give me $300 and I'll buy your favorite monitor for myself

 

[Heartbreaker]

For myself I need a 1600x1200 capable monitor, so it is the Dell or a new CRT.

So far I have heard good things:
Backlight level can be set to sane level (unlike 2405)
Viewing angles better than 2405.
(those were the main two reasons I ditched the 2405).

But now I hear two bad things that need to be resolved:
Banding?? Need more data. If both guys with the 2007fp could run some of the gradient tests in TFTtest(link above) or XTnight programs also above, we could resolve. I can't imagine them releasing a screen as messed up looking in the first picture. I hope that is some kind of anomoly because I think this is the screen that I want.
Strange coating on screen. Need more info on that.

So far it has promise.

 

[JMWarren]

I've had Dell send out a replacement panel. The gradient problem was due to a factory miss calabration. I was able to get it 99% right by playing with the settings in the service menu.

I'm really happy with it now, but the new one is already on it's way so I'll see if its better.

Color is great, brightness is more than enough, but can also be set low enough if you need accuracy.

Mine doesn't have the reflective screen coating.

 

[Heartbreaker]

Excellent. I figured that had to be some kind of anomoly.

Now I just need to wait for a dell sale...

Damn, I hate waiting...

Can anyone verify if that is a typo? I believe all the Samsung Panels start with LTM, the LG panels start with LM.

 

[JMWarren]

Nope It's a LPL UXGA LTM201U05

Hmmm so what does that make it?

So far all the Samsung PVA panels started with LTM. LG start with LM. See list below, or any panel lookup. LTM seems to make it a Samsung PVA.

The more I read the murkier it gets.


Panel list:
