LCD and PC connection via hdmi

[Andrew_12345]

Hello,
My Sony KDL-26S2000 LCD and Asus 6670 graphics card both have hdmi ports. However, when I connect them via hdmi ports, the resolution is 480 and I cannot change it. Does anyone know why?

Do you have latest catalyst drivers installed from http://support.amd.com/us/gpudownload/Pages/index.aspx ?

Yes but I still couldn't change the resolution. My LCD also has a VGA port but I think the HDMI port would be better, right?

Yes, it definitely would. DVI Would be great too if you monitor has that port.
