I wanted to connect my TV (Sony Bravia) to my Laptop. My laptop has a displayport and the TV a HDMI. So with the adapters, I'm able to connect those two, and that part works.
What doesn't work, is both screen are widescreen, but it does configure both of them automatically (Kubuntu 12.04) as 1048x768. With the gui tools of Kubuntu, it doesn't even give me the choice to change the resolution to a widescreen one.
xrandr gives me the following output:
xrandr --query Screen 0: minimum 320 x 200, current 1440 x 900, maximum 8192 x 8192 LVDS1 connected 1440x900+0+0 (normal left inverted right x axis y axis) 287mm x 180mm 1440x900 60.0*+ 59.9 50.0 1360x768 59.8 60.0 1152x864 60.0 1024x768 60.0 800x600 60.3 56.2 640x480 59.9 VGA1 disconnected (normal left inverted right x axis y axis) HDMI1 connected 1024x768+0+0 (normal left inverted right x axis y axis) 1600mm x 900mm 1920x1080 60.0 + 1280x1024 60.0 1280x720 60.0 1024x768 60.0* 800x600 60.3 640x480 60.0
How can I fix this?
