I am struggling with WMC on Windows 8 Preview. After installing I start the setup in order to use WMC with TV card (Working fine into Win 7). Playready installed fine, TV DAB-T found 33 channels, then I goes to full screen to adjust resolution. Alas .. Into the list the maximum res is 1600x900, my native resolution is 1920x1080, but no way to got it working it does not appear. First I think about GPU card a GTX-460 Nvidia. Un-installed drivers, perform a clean install with the latest drivers 301.xx whql , but no luck still 1600x900 max in WMC. Is there a way to force wmc to use native res at full screen ? any advice will be appreciated.
