This is on Ubuntu 10.04 with Gnome 2.30.2. The driver version is 7.7.1. glxinfo reports: OpenGL renderer string: Mesa DRI Intel(R) G41 GEM 20091221 2009Q4 OpenGL version string: 2.1 Mesa 7.7.1 I am using the HDMI output to connect to my KDE-P42HVX plasma TV. (This is a Japan model. The US equivalent is KDE 42XS955. The only difference between them is the tuners.) I have overscan in all 4 directions. The Gnome Monitor preferences panel says the monitor is a 'Sony 1"'. I gives me size choices of 1280 x 720, 720x480 and 640x480. The TV is 16:9 so I am using 1280 x 720. According to the manual the HDMI input supports 480i 480p, 720p and 1080i. About half the height of the panels at top and bottom of the desktop are cut off. Sometimes this increases to 2/3 being cut off. On the right-hand side the entire System menu is cut off. (Not sure if System is the menu name as I've never seen it. It contains Suspend, Restart etc.) On the left side, 1/2 to 2/3 of the show desktop icon is cut off. Is there a configuration file I can tweak to change the timings or screen size in order to fix this? I don't want to use 720 x 480 or 640 x 480 as that leaves too much of the screen unused.
I have discussed this issue with some of the engineers who work on the Intel drivers. It seems that the problem is entirely with the TV. There is nothing that can be done via HDMI to adjust the timings and if one reduces the number of pixels, you will still have overscan. It was suggested that I try the overscan control on the TV. On this TV it has 3 settings: standard, +1 and +2. It is set on standard. Needless to say, +1 and +2 make it worse. So I will close this as NOTOURBUG. For the record, the amount of overscan is the same in all four directions. The right side is no worse than the other directions. The rightmost System menu on the top panel is represented only by a small icon not text.
