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 1024x768 (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

Type this into your terminal: sudo cvt 1366 768. It will output something similar to:
# 1366x768 59.88 Hz (CVT) hsync: 47.79 kHz; pclk: 85.25 MHz
Modeline "1366x768_60.00" 85.25 1368 1440 1576 1784 768 771 781 798 -hsync +vsyncYours 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.
21I added a 1504x846 res (16:9) for my Dell XPS since the highest it had was "1366x768".
cvt 1504 846 60
xrandr --newmode "1504x846" 104.50 1504 1592 1744 1984 846 849 854 878 -hsync +vsync
xrandr --addmode LVDS-1 "1504x846"I then went to the "Menu -> Display" panel and picked it. profit!
note, run xrandr| grep primary to get your correct display name. Mine was "LVDS-1".
It sounds like you need to manually set your display resolution:
The settings are under Settings --> Displays. You need to set your resolution for that monitor to 1920x1080. See this YouTube tutorial.
