There's no H and V sync rates needed because they are implied*. If you have a fixed resolution the only variable will be the clock which will determine the snync rates. Just take a reasonable value there. As Ted pointed out TFT's shouldn't be too picky about sync rates; so don't worry too much and give it a go. An easy alternative: boot up a Live-CD (Knoppix, Freesbie) with X and check the xorg log (probably in /var/log). There you can find some values that work. regards Tino * There may be needed an hsync/vsync entry in xorg.conf though. Just specify a range big enough.
