I still believe the above is an appropriate patch to improve output of 576p given it is 50hz format you are right, fixed |

The TV out geometry of the intel driver is poor for the modes I use (PAL and 576p), although I suspect this is a general problem across all modes. The issues include not filling the screen (black bar at the bottom) and curved output that is not square on the screen. The patch below appears to help 576p somewhat, but is not a compete solution. Note the 576p refresh rate should be 50Hz. The windows driver works fine. Could someone with either access to the intel doco or the windows driver source code please look into this? --- a/src/i830_tv.c +++ b/src/i830_tv.c @@ -580,12 +584,12 @@ const static tv_mode_t tv_modes[] = { { .name = "576p", .clock = 107520, - .refresh = 59.94, + .refresh = 50.0, .oversample = TV_OVERSAMPLE_4X, .component_only = 1, - .hsync_end = 64, .hblank_end = 139, - .hblank_start = 859, .htotal = 863, + .hsync_end = 64, .hblank_end = 132, + .hblank_start = 852, .htotal = 863, .progressive = TRUE, .trilevel_sync = FALSE,
