sotti, my GTS250 also expands to desktop levels. Did a test with DVE HD BD reverse grey ramps pattern.
1) Opened TMT3 on my main Dell 2407WFP RGB monitor and minimized and maximized program, and then did the same on my Samsung LCD connected via HDMI adapter, and which only accepts 16-235. Pattern looked exactly the same (calibrated for 0-255).
BTW HDMI Digital Color Format set to YCbCr444 and Video color Settings to "With the Nvidia settings".
2) I then opened another 1080p grey ramp pattern from .ts file with WMP and it was OK on the Dell, and compressed on the Samsung. Just went to Nvidia CP, and adjusted Video color Settings to "With Video Player settings" and now got no compression with minimized and maximized WMP window, exact same pattern as on the Dell.
3) With these same settings I opened 7MC and put AVIA DVD to display ramps gray pattern, and moved MC to both displays. It showed fine on the Dell but definitely with DOUBLE COMPRESSION in MC
(using MC player). Using 7MC native decoders.
4) Tried now with WMP and it worked just fine in both monitors.
SOOO ... after more than a year since the release of Vista I have to conclude that the dreaded Media Center double compression bug
is still there with Nvidia drivers for 16-235 display devices (so beaups is utterly right! Thx beaups!
). I didn't notice because I really do not use MC that much, and when I do I use other decoders like ffdshow.
