Green Tint: Gamma Settings not applying to Video

[jarsoffart]

My monitor is calibrated fine. When I play a video in VLC or WMP 6.4, it has an extremely noticeable green tint. If I cover the video with another window and switch back, it will display the correct colors for about 5 seconds before abruptly switching back.

Possible causes: I just upgraded from Windows 2000 Professional to Windows 2000 Server. I installed the latest nVidia drivers following my upgrade. Previously I had been using an old version in Win2k pro. The last change I can think of is the addition of a RAID 1 array. Previously I did not have any drives in any arrays. However, video files from both the RAID array and the non-arrayed drives suffer from this problem.

Thanks in advance for any help one may offer.

"Solution:" So I disabled Adobe Gamma (which consists of just removing it from the Startup folder) and then used nVidia's color correction portion in their drivers. I adjusted the "Desktop" portion to my liking under the Advanced Mode and then went to the "Overlay" portion and adjusted the brightness to my liking under the Standard Mode. The "All" option didn't seem to affect the video at all. Configuring "Overlay" in the Advanced Mode didn't seem to affect the video either. This solution seems kind of ghetto to me as I'd prefer if both my desktop and my video appeared the same, but I'm not going to spend anymore time on it.

Update: So the above "solution" turned out not to be a solution after all. So by adjusting the brightness I was able to finally see less than bright scenes but they still possess a noticeable green tint. This could easily be solved if the "Advanced Mode" with separate channel adjustments was available. I've also noticed that any gamma changes in the "Advanced Mode" for "Overlay" have no effect. The only useful mode for "Overlay" is Standard. Also, I do indeed have VLC to use overlay.

My problem I think now essentially boils down to how to get separate channel adjustments available in the Overlay section of the color correction and get the Advanced Mode changes to actually have an effect on the video or have All portion actually apply to all, both desktop and video overlay.

Are you running a pci-e system?

Nope. I have a pretty old system.

Abit KR7A-RAID
Athlon XP 1700+ T'bred
640 MB PC2100
Leadtek GeForce2 MX200
Creative Audigy
1x Seagate 7200.9
2x WD1200JB (in RAID 1 Array)
1x WD1600JB

There is video color adjustments in drivers normally

Adjust the "Overlay" settings in the nVidia utility does not affect the video. Is it significant that I'm using the "Adobe Gamma" utility to adjust my colors?

I know this doesn't directly apply to you but on my ATI card drivers there is a section for video color adjustment. You probably need to find that in yours

Do you have "Overlay video output" checked in VLC? Perhaps you are rendering using VMR instead of overlay...hence overlay settings won't affect the video.

Does the issue occur with a specific video format, or all videos?

I've tested out WMP 6.4 and VLC with DivX, DV, and HuffyUV video. I've tested VLC additionally with a DVD. Same results across the board.

I'm not exactly sure if this will work for you since you are on an agp system, but give it a try. Run dxdiag, under Display, disable the agp texture acceleration.

Doesn't help. ) :

It may just be a driver issue thats affecting the overlay. I don't see if you tried VMR rendering to see if it is still an issue, but I do know that video rendering bugs are quite common with driver builds since they are secondary priorities to 3D performance.

How do I use "VMR rendering?" From what I can glean from Google, it's some codec/filter? Either way, I read somewhere that it was first for Windows XP, but then now I can download it for any DirectX platform? I see a lot of references to DirectX 9 and I'm pretty sure my GeForce2 MX200 does not support that. Also I can't find any downloads pertaining to "vmr" at the MSDN site (http://www.microsoft.com/downloads/resu...teria=popularity&nr=20&DisplayLang=en).

In short, do you think you could elaborate about VMR to a total noob.
