[suggestion of 50hz booter deleted] The TV is flipping because the program successfully set the video to 50hz already and the TV is having trouble syncing up. A 50hz booter won't help the situation. You really need to be able to tweak the vertical hold... I'm sure the TV has the control internally. (Dunno, maybe these modern all-digital ones don't. Haven't looked.) Just fyi, another reason to switch to 50hz - you get 100 more scanlines on the physical display, of which the ST can use maybe 80 more, max. But also, getting vertical blank interrupts at 50 instead of 60hz probably does free up a chunk of CPU time... total aside... I'm looking into hooking up a 25" Proton monitor/receiver to my ST. This model has an RGB input, so it oughta look pretty slick. Apparently new video equipment is all going with S-connectors, tho - anyone have a nice kit to convert RGB to YC video? -- -- Howard Chu @ Jet Propulsion Laboratory, Pasadena, CA Disclaimer: How would I know, I just got here!
