I just got a new 8600GT, thinking it'd make 1080p movies playable on my comp, but though they are, the colour seems quite washed out. Blacks are dark greys, and the colour is just generally pretty dull. I didn't have this problem with my X800XL and I've tried reinstalling codecs. I've got the 158.22 drivers.

If I force ffdshow to RGB32 and untick the other settings, the colour's fine but the video is unwatchably laggy. Has anyone else had this problem? Someone please help.
 
I didn't think that the hardware decode would work unless you used a supported decoder, something like the one from the newest version of PowerDVD, and Windows Vista.
 
Well it obviously is working, considering the massive improvement in playback speed. I wasn't able to play 1080p h.264 videos before and now I can do so with an 80% CPU load. It's not working anywhere near as well as it would on Vista, but still, it shouldn't affect image quality.
 
I have the 8600GTS evga n761 in my 939 system and works great with 158.19 Driver and was buggy with 158.22... I used PowerDVD with both drivers but stuck with 158.19!:D
 
Ok cool I'll try that. But the videos I'm having issues with aren't DVD's. They're just any kind of video file, like avi's or mpg's or mkv's etc.
 
Exactly dosnt matter happens right after you done gaming or even switching windows .... Ive had mine display overly bright after installing certain 158.XX drivers as well ...Go thru the drivers and make shure your MediaPlayer is up to speed as well...I know it suks ..Good luck
 
Here's the problem: if you're using ffdshow to configure your display settings now, you're doing something wrong. ffdshow can't interface with nVidia's drivers. For X.264, basically all you can use with FFDshow is libavcodec. You need to use purevideo, if I'm not mistaken, in order to take advantage of your card's X.264 decoding capabilities (I don't have an nVidia card of any kind so don't quote me on this).

Here's what I suggest:

- Download graphedit (http://www.videohelp.com/tools/GraphEdit) and drag anything with H.264 / X264 video (preferrably a .mkv so we can make sure the splitter is working correctly too) into it. Post up the picture or analyze on your own. Basically, this will tell you which directshow filter is being used when the video is opened.

- If FFDshow IS being used for H.264, make sure to disable it in the video decoder settings. Then drag the .mkv into graphedit again and make sure everything is hunky-dory.

- If nVidia's codecs are being used, great. Then it's a matter of finding out how to configure the video settings for it. My guess is that the contrast is turned down or that the luminance levels need to be fixed. You can probably configure it in video settings if it's anything like ATI's AVIVO stuff, but I don't know.

Of course, this is contigent on whether or not your video is X264 or not, since you didn't specify what format the video was in, but I can't imagine anyone encoding 1080p video in anything other than that...
 
Ohhhh good point !Do you use PowerDvd with it or some other DVD version it installs certain codecs for play back ...

well WinDVD or PowerDVD or NvidiaPureDVD which would be required for Codecs to optimize playback ...This will optimize it in AVI and Media player if i remember right and i installed the newest DivX as well ...Just a thought
