My on-board Radeon HD 4290 video, along with my 24" LCD are having trouble displaying 1920x1080 resolution on Windows 7.
I have a new Asus M4A89GTG Pro motherboard with on-board Radeon HD 4290 graphics. I have a Sceptre 24" 1920x1080p capable montior attached via VGA (through a KVM). I know the monitor can do 1920x1080, as my Windows XP system displays it just fine.
The new motherboard, along with the latest Catalyst Display drivers from ATI seem incapable of displaying 1920x1080 resolutions. The Sceptre monitor doesn't seem to have Windows 7 drivers, so I've used the default 1920x1080 60Hz flatpanel as the monitor type (switched from Standard PnP). The Catalyst software will recognize the resolution, but won't allow 60Hz, but rather gives me some interlaced refresh rates, which the monitor can't display.
I'm not sure if the problem is with the drivers, monitor, or Windows 7. Any help much appreciated as this is frustrating me immensely!
