OTish: WMP, AMD (ATI) Cards, & Video Levels

Well here's a fun waste of a couple hours: I suddenly noticed the video levels were wrong playing mp4's with Windows Media Player.

I checked my laptop and found no troubles there, so I started thinking what did I change on my desktop. The answer was my video card--the old one died.

My new card is an AMD model, and in the 'hydravision command center' there is a setting to seize control of the player and enforce 0-255 or 16-235 levels. Neither setting worked, though, and neither did leaving the player on its own. The levels were wrong no matter the setting (though they did shift).

Finally...I found a setting in another screen called 'dynamic contrast'. That was on by default. Turn that off, and finally WMP is back to normal. Sheesh! Thanks a lot, AMD.

FYI, the VLC player showed normal levels regardless of these settings. Maybe Hydravision doesn't recognize it as a player and doesn't try to seize control of it?

Anyhow, if you're experiencing something similar, turn off dynamic contrast.

Thanks for sharing. I'd like to have a video adapter that just turned pixels on and off without "getting all up into my bidness", but alas it's not to be anymore.

Yes, on AMD (and likely others) one should turn OFF all their custom video tweaking options.

In AMD the "Advanced video color" options and the options under "Video quality". All these alter the video as encoded. Nor the better as they might say. AMD defaults to all these options on.

Also, with AMD when you update the driver your settings get reset, so remember to go in and clear them again.
