QDI screen - looks cool - but only the first look - Page 3

It looks similar, but it is far less intensive, and "grain" is smaller. I wouldn't worry about it, because right now I can see it too, even if I don't have mentioned noise with current driver. Try Omega 6.3 and check blank screen when driver starts, or just black background in movies - it wasn't pure black in my case...
With Omega 6.3 it looks a bit better, but I got some errors during installation and can't change the gamma and other stuff. Will take a look at it later.

BTW, black backgrounds looks good on my screen...

Well, today I have seen the new nx9420 from HP. The lowest configurated model. It was coming wioth X1600 and 1440 x 900 of resolution at 17". All I saw was:

1.grey lines
2.the noise present there, but much less than on 8204
3. Buzzing on TOKAMAK (only barely audible, but there)

Hey guys, maybe the X1600 has issues by itself. I mean it really was veyr poor scren with a lot of light leakage and too dim (reminds me some of the 8204s) but well this is getting kinda mystic with the noise on the pictures or textures as this was third, completely different screen. I mean I needed to search for the nosie, but yeah, it was there. I guess it may be driver related. Just wondering not too many noticed that so far...

I see the "grain" on that webpage. But I see this grain on other LCD screens, but not on that type of color. I see the grain on lighter colors.

You can see the problem on the background of this website, where I just downloaded the hibernation patch:

http://www.thegamebooks.com/ezdloads.php

The background is not a solid color (as it should be) but rather grainy pattern that doesn't change when moving the browser window! The pattern is static and changes when you tweak the gamma settings.

Can someone try and tell me if that is the same with the LT screen? By the way, I am using the stock driver and settings with a gamma of 0.95.

Ok. I've just check that website on my desktop at work. That background is solid grey! It is much darker than on my 8204 screen, but it is solid color. I have an old ATI video card here. BTW this LCD has grey lines also... It looks like X1600 doesn't show dark colors properly... So software or hardware issue, what do you think???

Altogether with buzzing it looks like it is hardware related natively, which does not make me too too happy, because my next purchase is ment to be HP with X1600, I just want to get this mystery solved before I decide! Well, this webpage is absolutely solid grey. I am using Radeon 9000 and no noise anywhere, superclear colours...

I connected two external monitors via the analog standard vga output. One CRT and an 18' Sun TFT. Both external monitor displayed the background as a solid grey color! I haven't tried the DVI output but it's probably the same.
What does that mean? If you ask me, it looks like the problem is either the monitor or the digital interface. I don't know much about the latter and it sounds strange, so i assume the QDI screen is the problem (at least in combination with the X1600).

Concerning this webpage (or the dark grey color) it helps to set the gamma to 1.3. Surely this doesn't solve the overall problem and that's sucks .

So basically this can kinda tell, that X1600 is not the main problem. Or maybe the way how does it display digital info on LCD notebook flat panels might be wrong. But I still think it is due to the poor quality of the LCDs, I second that. But as it is common for LTN, QDI and also this UPwgatever screen it was on the HP, it still sucks, cause there is some cheep crap being mounted into so called highend systems and that is simply not right.

I thought it was obvious for awhile now the buzzing on the x1600 was hardware? Because the some of the Macbooks exhibit the same issue

I could live with buzzing, but if colors are displayed improperly - that's the real issue... But I still think/hope that it could be resolved with proper driver... Maybe we should ask ATI directly? Maybe that's why the newest drivers do not support Mobility X1000 series yet?

Unfortunately that might be truth I hope this will be resolved soon, but ATI should kind of say something about. Cause they are not promoting many brands in too too nice way..ehm...

Is there any chance to get the older drivers? Just to see if the splotches or whatever it is dissapears. Because if it is ATI GPU hardware issue, then they are not gonna be too too successful with their x1600 - as it is mounted into all common high end notebooks.

Is there anybody who can confirm it is or it is not GPU related? Cause if it is jus screen related - OK change the screen or notebook manufacturers, but if it is GPU related then we are stuck as there are not too many options to switch to!

How about these guys exchaged the screens? There was somebody who went for WUXGA - still problems there?????

Have you tried attaching an external monitor/LCD to your laptop to see if you see the same thing? That would tell you if it is the GPU or not.

Gismo tried to.
I'm confused. I've reinstalled the newest Acer driver (catalyst 6.3) and I don't get that noise in the shadows! I did it couple of times before and noise was always there, but now it's gone! I still get a noise on that website, but it looks less intensive than before... Any ideas?
BTW, my webcam seems to work how it should since my last system reinstallation. I used the same recovery DVD as before... I don't understand that...

Well, that is strange...did you just purely reinstall?? And all the noise is gone, or is it just less intens?

Noise in dark colors disappeared completely! Or maybe didn't appeared again cause I didn't get it since I've come back to original driver... So now I have Acer 6.3 driver and no noise also. Maybe that's a matter of my last "magic" system reinstallation? I had some error messeges in 3DMark05, but now I get 4523 pts. (and 2000 pts. in 3DMark06 as well) with no overclocking! Previously, I had 4502 and 1954 with Omega 6.3 and dark background noise as a bonus...
I still get a noise on that website, but it seems to be less visible. I don't belive in self-repairing computers, but I cannot explain it...

Hmm, I can confirm but not explain! As jaad75, i installed the Acer 6.3 driver and the noise is not gone, but the webpage looks better than before (with the Omega 6.3 drivers). But there is still a huge quality difference with different screen settings (brightness, gamma and contrast). How can that be?

Right now my settings in the CCC are: 1,15 gamma, 0 brightness and 100 contrast. I notice a huge difference between gamma 0,70 (no noise at all) and 0,75 (heavy noise). Can anyone confirm that?

Anyway, i think i can live that. BTW, got a 3dmark06 score of 2001 (default settings 473Core/468Mem)
