You need to adjust the display area of the mode relative to the total. For example: Modeline "1280x720" 74.50 1280 1344 1472 1664 720 723 728 748 -hsync +vsync Modeline "1280x720underscan" 74.50 1170 1344 1472 1664 660 723 728 748 -hsync +vsync Note that the total values are constant: 1650 -> 1650, 748 -> 748, while the display values have been reduced: 1280 -> 1170, 720 -> 660. Try one of those modes, or adjust your own based on the 1280x720 timing from your tv. xrandr --verbose will print the full modeline. here are some others I found on the web: ModeLine "1176x664a" 74.250 1176 1390 1430 1650 664 725 730 750 +hsync +vsync ModeLine "1176x664b" 74.250 1176 1338 1378 1650 664 697 702 750 +hsync +vsync ModeLine "1200x670" 74.250 1200 1208 1248 1980 670 700 705 750 +hsync +vsync Alex _______________________________________________ xorg mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/xorg
