I have a Dell s2409w, 24" 1080p monitor. With nVidia, I would plug-in the monitor and voila, it automatically knew it was 1080p (1920x1080).

I have both a Windows laptop and Ubuntu laptop. Neither is capable of using the fullscreen even though the monitor reports the input is 1080p.

I am connecting the monitors via HDMI, is there a 'special' setting I am missing to make this work?

Otherwise, I like the performance of my ATI video cards, the drivers seem to be stable and reliable.

Thanks,

Walter

What model of ATI video card do you have?

It seems that with driver release 9.10 of ATI Catalyst they fixed some problem with Overscan/Underscan, I suggest you to update to latest driver release and see if it solves it.

ATI cards seem to interpret 1920x1080 HDMI as a TV mode and set an underscan of 15% by default.

I have connected up my HD3200 to both a 1920x1080 TV via HDMI and a 1280x1024 LCD via DVI and this only happens on the TV.

For some reason they hide this setting away as well.

In Windows you need to go to the ATI Catalyst Control Center and select the Desktops & Displays section.

Then use the dropdown menu from the triangle on the small screen icon at the bottom.

Select Configure, then the Scaling Options tab.

Have you tried the custom Radeon Mobility drivers at DriverHeaven.net?
