So for a while I have had an old EMA 15" monitor hooked up to my Ubuntu machine running Ubuntu 15.04. The Monitor runs 1024×768 (4:3). At this point all is fine. But I hooked my computer to my Sansui HDTV and it will not let me have a 16:9 ratio so it is in letter box. How do I fix this?
NOTE: I am using a VGA cable between the TV and COMPUTER. Also I am used to Ubuntu and the terminal so please HELP!!!
$ sudo xrandr -q
Screen 0: minimum 8 x 8, current 1024 x 768, maximum 32767 x 32767
VGA1 connected primary 1024x768+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
1024x768 60.0*
800x600 60.3 56.2
848x480 60.0
640x480 59.9
VIRTUAL1 disconnected (normal left inverted right x axis y axis)
Best Answer
Type this into your terminal:
sudo cvt 1366 768
. It will output something similar to:Yours may be different than what I have, so copy everything after "Modeline" from your terminal.
Now paste in what you copied into this command, e.g.
sudo xrandr --newmode "1366x768_60.00" 74.50 1280 1344 1472 1664 720 723 728 748 -hsync +vsync
The final step is to add the new resolution to the VGA1:
sudo xrandr --addmode VGA1 1366x768_60.00
That should give you the resolution you want for the TV.
To keep the settings after restart use the answer here with your settings and you won't have to redo it.
