bought a new 6570 to install in Dimension 5150 running with 2.5gb 533mhz ddr2, and ssd. Using latest catalyst and drivers. Monitor Logik FullHD 1080p L24DVDB19 tv on VGA and HDMI. Windows 7 Ultimate SP1.
After installation, the new card won't correctly detect a 1920x1080 display as available. Maximum working resolution 1440x900. When I turn off EDID in catalyst, and force 1920x1080 60hz, I get a visible display but lose a considerable portion of the left of my desktop as if to an extended display.
When I remove the card and run my Integrated graphics Intel 82945g, it detects the 1920x1080 display available and scales and displays correctly.
Also the card won't output HDMI, (or my TV won't detect any output). Whe I connect the HDMI and VGA at the same time nothing happens. Catalyst does not detect any difference.
