I dont mind if it gets streched. =) Its native resolution is 1920x1200 at 60hz. Standard 24" 16:10 LCD
I can try HD720 but that will only be for workbench I guess. Need to get rid of color shift on PAL to get the games running.
I've tested standrd PAL (last screenshot), PAL-Interlaced and HighGFX in 1024x768. All looks "good" with old default core.
