The problem I have (and one I've seen other ATI users mention) is significant underscan when outputting a signal to the monitor. By that I mean, there is about 1 cm blank space around the desktop in HD Size 1 and nearly two cm of blank space surrounding the desktop in HD Size 2. I saw a mention of changing the refresh rate of 60hz to 59hz as a possible solution, but 59hz is unsupported by the Catalyst drivers when using HDMI (except for 1280x720 @ 59hz). Using a lower resolution still maintains the black bars around the desktop.
Interestingly enough, the PS3 I have hooked up to the HDMI input #2 displays a full frame picture just fine at 1080p.
For those of you using the TC-32S1 as a PC monitor, can you reply with your video card, driver revision, and operating system? Do you see a full frame? Or is there a blank surround on your desktop?
I'm using catalyst version 9.10, using an ATI 4870 with windows XP temporarily (waiting to install win 7 on this particular PC) and i have perfect 1:1.
I found the option for 59hz under ->
Catalyst control center -> "
Display manager -> Display properties". After i set that, i had to set it in the generic windows display properties as well (they both must be set to 59hz).
In the catalyst control center i also had to enable "
Image Scaling" and check off "
Centered Timings" or "
Maintain Aspect Ratio" (both work for me).
In the TV menu, set it to "
HD size 2" and leave it there. Disable all image processing extras, set sharpness to "0" for now, you can try messing with sharpness later btw.
Took a bit of tinkering,
and rebooting the TV and computer a few times to get it right. But once you get it working it should remain flawless. There were a couple of times when windows or catalyst would "secretly" revert back to 60hz. I say "secretly" because it would still say 59hz, so i would temporarily put it to 60hz, then back to 59hz to get it working again. This has only happened to me twice and not anymore, i've never been able to recreate the problem since. Pretty sure rebooting the TV would have worked also. Having two video control panels (windows + Catalyst) complicates things a little bit i think.
