I've been trying for the past couple of weeks to fix the overscan on my KDE destktop (Orbiter displays fine). I'm out of ideas, and I could use some help.
My 1080p Samsung DLP TV is connected by HDMI to the hybrid. Orbiter displays nicely. KDE desktop is overscanned by a couple percent on all sides, top & bottom: on the bottom, I can't see about half of the panel. I've customized the modeline ad nauseum to no avail. Here are some of the websites I've looked athttp://forum.linuxmce.org/index.php?topic=7732.0http://ubuntuforums.org/showthread.php?t=1003099&page=2http://wiki.linuxmce.com/index.php/Display_Drivershttp://en.wikipedia.org/wiki/Modelinehttp://www.mythtv.org/wiki/Working_with_Modelineshttp://www.mythtv.org/wiki/Modeline_Databasehttp://www.mythtv.org/wiki/Configuring_TV_output
I've tried various EDID settings, with no effect.
I've tried countless different "customized" modeline settings using calculators, the MythTV Modeline Database, and Google + Samsung + Modeline. When I tried making my own tweaked modeline using the instructions found here (http://ubuntuforums.org/showthread.php?t=1003099&page=2
), I was able to change the size of the screen, but not the position. Some background numbers:
148.5 1920 2008 2052 2200 1080 1084 1089 1125 (This is my default 1080p setting, slightly overscanned on all screen edges).
148.5 1800 2008 2052 2200 980 1084 1089 1125 (This makes the display region smaller, so that I can see the right & bottom edges of the generated display...ie: the mouse pointer stops moving at the black edge on the right & bottom)
148.5 1800 1887 1931 2200 980 1084 1089 1125 (This should
have moved the "screen edges" to the right, but nothing changed(?!?). Very confusing).
148.5 1800 1886 1930 2200 980 1084 1089 1125 (This gives an unusable display)
Also, using or excluding +/-hsync or +/-vsync made no difference to the result (yes, I tried all the iterations on several of the modelines. I even tried using HSync & VSync, since there's a disparity on some of the MythTV pages about capitalization).
My PS3 displays 1080p content on the TV without problem, so the issue should be in the hybrid somewhere.
I'm running 7.10 on the hybrid.
Any help? My head's starting to hurt from this wall it keeps banging on.
