[Bug 622347] [NEW] Can not increase screen resolution when connected through TV tuner card

 

You have been subscribed to a public bug:

I am using Ubuntu 10.04 in my PC. Now I connected LCD monitor through
LCD TV BOX (External Tuner Card) and hence I can not increase screen
resolution. I can only select only 800x600 and 640x480.

The out of 'xrandr' is

Screen 0: minimum 640 x 480, current 800 x 600, maximum 800 x 600
default connected 800x600+0+0 0mm x 0mm
   800x600        60.0*    56.0
   640x480        60.0

When I connect LCD monitor with out Tuner card there is no problem. Then
out of 'xrandr' is

Screen 0: minimum 640 x 400, current 1360 x 768, maximum 1360 x 768
default connected 1360x768+0+0 0mm x 0mm
   1360x768       60.0*
   1280x768       60.0
   1024x768       75.0     60.0     70.0
   832x624        75.0
   800x600        75.0     60.0     72.0     56.0
   640x480        75.0     60.0     73.0
   720x400        70.0

Please help me to solve this problem.
