I recently changed from win7 32bit to win7 x64. During the process I updated to latest ATI video drivers etc. (I'm using integrated Radeon 4200 video).
Now I'm having problems with full screen video that I've not had before.
OLD:
- Dharma 10.1
- Set the overscan setting in the video driver to "0" fill the screen.
- Set "adjust display refresh to match video" in xbmc to ON
- Set "sync playback to display" in xbmc to ON
- Set TV to film mode (24hz)
When launched, the indicated display (on tv) for windows applications and xbmc was at 1080p and when a video was launched in xbmc the TV would automatically sync to it, indicate "1080p 24hz", and the video would play in full screen right to the bezel. No jerky playback etc, just smooth video. When the video stopped, the tv indicated "1080p" and the display would remain filling the screen for whatever apps I was using.
NEW:
- Dharma 10.1
- Same settings as above
- Changed OS to win7, 64
- Updated video drivers (cannot go back)
Set the overscan to 0 in ATI/AMD driver to fill the screen. System performs the same UNTIL I launch a video. At that point the screen size shrinks to underscan by about 7%. TV indicates 24hz, but the video plays in that underscanned mode. When I stop the video, the display (for xbmc AND windows apps) stays in that underscanned mode. When I go back into the video driver the scaling setting has reverted back from 0 setting to 7. I can reset the overscan to 0 in the driver and the display is once again filled, but as soon as I play a video in xbmc it happens again. Why?
I can force the vid card to output 1080p 24hz, and the issue goes away. But I never had to do that before. I'm also finding the video is not as smooth as it used to be. Mouse seems to be laggy too. (I'm not sure how to post a log)
Thoughts on how to get back the quality I had (without going to back to win7 32bit)?
TTG
