as described in README, I changed /etc/S17hdmicfg to 1080p@60 and recompiled the kernel for serveral resolutions: 800x600,1024x768,1368x768,1680x1050 and 1920x1080. However, no greater fb/LCD resoluion than 1024x768 (and the default 800x600 of course) will work.
Is it possible (how?) to get a full screen fb window?
