Thanks. It turns out that I need different values to fit the screen (probably due to native 1366/768 != 1280/720). This is of course at the cost of slightly changing the rendered ratio, but that's fine with me. Any plans to make those values tunables? Also, I kind of was hoping that once I could use 1280x720 for both the console and the X screen, it would would allow me to switch between the two transparently. Instead, the TV takes notice of the switch and needs some extra syncing time. Is this expected behaviour? Thanks Marius
