| My Samsung TV (LE26R41BD, panel resolution 1366x768) happily accepts
| any reasonable input over HDMI. If queried, it claims to only support
| the usual HDTV modes (720x480/576, 1280x720, 1920x1080i), but if
| another mode is forced it works just fine. For the VGA input, all the
| usual adjustments are possible through the onscreen menu.
Any chance it "works just fine" on frame rates below 50 Hz, like maybe at
24 Hz?
