With my TV I've tried running vdr-sxfe at 1360x768 at 60 (which the TV does
accept over HDMI, but not VGA), 1280x720 at 50 and 720x576 at 50. Surprisingly
720x576 seems to look a bit rougher to me than the other two
resolutions. I find 1280x720 is slightly better than 1360x768 for VDR
because of the matching refresh rate.
