I recently built a new computer and am having an incredibly difficult time getting the graphics card (XFX Radeon 5770) to function properly with Windows 7 (via HDMI).
Everything looks a bit blurry, especially the text. HDMI, DVI, and VGA connections all look terrible. The only success that I have had is by using a "Composite Sync" feature with VGA, that is stated not to be supported by Sony. The text became clear with that feature, but the corner of the screen was cut-off/folded-over and flickering. My goal is to get things working with HDMI.
A few notes:
* Running the the most recent ATI drivers (10.6)
* Pixel ratio set to 1:1 on the TV
* Using native resolution (1080p/60hz, also tried 59hz without improvement)
* Overscan set to 0%
* ClearType text has been adjusted
* Tried older drivers: 10.5, 10.4, and 9.8 without success
With the "Composite Sync" feature for VGA connections having been my only partial success, I'm wondering if Catalyst is actually outputting the signal with the displayed 60hz refresh rate, or if there is a problem with one/both of the vertical/horizontal frequencies.
After spending dozens of hours on Google and reading posts about similar issues that had been solved by simply setting 1:1 pixel mapping or eliminating overscan, I'm fresh out of ideas and starting to go crazy.
I would return the card, but I'm only eligible for a replacement card of the same model, and this seems like it is probably a Windows or ATI software issue.
Does anyone know what might be causing this and how to fix it?
