Display Resolution – Unable to Set Screen Resolution Higher

displaydisplay-resolution

I'm running Ubuntu 16.04.5 LTS on this system

Processor: Intel Core i5-7400

Mainboard: H110M-Gaming3-CF

The problem is the highest resolution it can go up to is 1024×768, which is terrible. How can I set my resolution to a higher resolution (i.e. FHD which fits my screen)? Thanks.

Ubuntu or the other versions of it like (k,l,x,edu,etc.,) are required to add the resolution we want to set on some monitors.

So follow my steps:-

  1. Open a Terminal by CTRL+ALT+T

  2. Type xrandr and ENTER

  3. Note the display name usually VGA-1 or HDMI-1 or DP-1

  4. Type cvt 1920 1080 (to get the --newmode args for the next step) and ENTER

  5. Type sudo xrandr --newmode "1920x1080_60.00" 173.00 1920 2048 2248 2576 1080 1083 1088 1120 -hsync +vsync and ENTER

  6. Type sudo xrandr --addmode VGA-1 "1920x1080_60.00" and ENTER (replace VGA-1 with your display type (step 3) like HDMI-1 or DP-1)

  7. Now close the terminal and go to Settings >> Display settings and change it to 1920x1080

  8. Enjoy FHD.

To make the above settings stick when you restart your computer, do the following.

For integrated displays

  • goto your terminal and type vim ~/.profile ENTER
  • Paste in the shell command from step 5 and 6, then save.

For external displays

  • create a script called external_monitor_resolution.sh in the directory /etc/profile.d/. using sudo vim /etc/profile.d/external_monitor_resol.sh.

  • Paste in the shell command from step 5 and 6, then save.

(Note: if using sudo would require you typing a password, your system might freeze on startup while waiting for you to input a password. So when pasting do away with the sudo) Something like this:

xrandr --newmode "1920x1080_60.00"  173.00  1920 2048 2248 2576  1080 1083 1088 1120 -hsync +vsync
xrandr --addmode VGA-1 "1920x1080_60.00"` and <kbd>ENTER</kbd> *(replace **VGA-1** with your display type (step 3) like **HDMI-1** or **DP-1**)*
