Serious Desktop Color Problem with ATI 5650

Hi,

I don't know how I never noticed it but, there is a severe color range issue with the 5650 in my laptop. The switchable 4250 is fine, all the gradients are smooth, but the 5650 is presenting very limited colors and all gradients have grainy and pixelated transitions. Catalyst is already on 32-bit color so I don't know how I can correct it...it feels more like 16-bit or lower colors right now.

Edit: never mind, I tweaked the colors too hard. This laptop screen isn't nearly as vibrant as my Lenovo's but I wasn't convinced, so the contrasts/gammas/brightness were off the charts and screwed up the gradient.


Edit 2: see my post below.




Edit 3:

Here are picture examples:

Some gradients,


What I see (left part), you can clearly see pixelated transition near top, and a sudden cutoff near bottom where it should transition smoothly to white,


(right part): gray gradient cuts off as well, as you can see,

 

i have such problem in windows 7 and ubuntu on my Aspire 5551G

 

Okay it's either an ATI driver problem, or the screen quality, but after an hour of tweaking, I've concluded that the color issue resides in that the screen can't display bright grays. So if I tweak the contrast/brightness so that whites are white, there is an empty gap on the bright end of the grayscale gradient, where it's supposed to be white transitioning to bright gray, but is all white and then a sudden pixelated jump to a darker gray.

This also affects color gradients because they also utilize brightness controls to achieve how dark the colors are. Basically the brighter end of colors are washed out and have zero gradient.


My screen on this Acer is an AUO, is anyone else with 15.6'' AUOs and ATI 5650 having this issue>?

 

My laptop have AUO Display too (Acer ASPIRE 5551G-N934G32Mikk).

 

Does yours have the identical problem (bright shades of grays/colors washed out completely)?

 

Bump!

Come on, most people here w/ 3820/4820/5820TG, among others, should probably have an AUO screen and ATI graphics, does no one else have this issue?

 

Please see first post again, I added some photos in comparison with real images.

Edit:

Also, do any of you see a "zigzag" in the middle of this test image?
