Either that or keep googling X org and PAL TV's. I think it is something with the refresh rates though. Also the H-sync should prolly be 50 hertz locked as this seems to be PAL's standard refresh rate. X might be defaulting to the low end which is causing the flicker. It might help to define the resolution you want the screen to have as well. PAL supports a few different ones at different levels of fidelity. Again X might go to the low end of things to be safe which is just causing the interlacing to occur too slowly and flicker on you. good luck -brian
