-Or install arandr using this command+===== How to manually set a monitor resolution ===== 
 + 
 +==== Manual way ==== 
 + 
 +1. Check present resolution: 
 + 
 +   xrandr -q 
 + 
 +An example output is: 
 + 
 +   VGA1 connected (normal left inverted right x axis y axis) 
 +   1024x768       60.0  
 +   800x600        60.3     56.2  
 +   848x480        60.0  
 +   640x480        59.9  
 +   DP1 disconnected (normal left inverted right x axis y axis) 
 + 
 +2. Generate ‘modeline’ using ‘gtf’ command: 
 + 
 +   gtf width height refresh-frequency 
 + 
 +Example: 
 + 
 +   gtf 1366 768 60 
 + 
 +The result is: 
 + 
 +   1368x768 @ 60.00 Hz (GTF) hsync: 47.70 kHz; pclk: 85.86 MHz 
 +   Modeline "1368x768_60.00" 85.86 1368 1440 1584 1800 768 769 772 795 -HSync +Vsync 
 + 
 +Where is: 
 + 
 +  * 1366 - width 
 +  * 768 - height 
 +  * 60 - refresh-frequency 
 + 
 +3. Set your resolution copying the last output of **gtf** command, starting after **Modeline**: 
 + 
 +   xrandr --newmode "1368x768_60.00" 85.86 1368 1440 1584 1800 768 769 772 795 -HSync +Vsync 
 +   xrandr --addmode VGA1 1368x768_60.00 
 +   xrandr --output VGA1 --mode 1368x768_60.00 
 + 
 +It is only temporary solution, after rebooting all the changes will be lost. 
 + 
 +---- 
 + 
 +To make it permanent, do: 
 + 
 +1. Create a new file in your home directory, for example **.mymonitor**: 
 + 
 +   nano .mymonitor 
 + 
 +2. Copy previous 3 commands you used for manually setting the monitor, and paste onto the file:  
 + 
 +   #! /bin/bash 
 +   xrandr --newmode "1368x768_60.00" 85.86 1368 1440 1584 1800 768 769 772 795 -HSync +Vsync 
 +   xrandr --addmode VGA1 1368x768_60.00 
 +   xrandr --output VGA1 --mode 1368x768_60.00 
 + 
 +3. Make the file executable: 
 + 
 +   chmod +x .mymonitor 
 + 
 +4. Add the ~HOME/.mymonitor file to the system startup. 
 + 
 +More information about XRandR can be found via commands: 
 + 
 +   xrandr --help 
 +   man xrandr 
 + 
 +---- 
 + 
 +==== Randr/XRandr GUIs ==== 
 + 
 +There are a few frontends for Rand/XRandr, such as: 
 + 
 +   * LXrandr 
 + 
 +{{:lxrandr.png?300|}} 
 + 
 +   * KDE Workspace Randr 
 +   * Arandr  
 + 
 +To install arandr use this command:
  
     sudo apt-get install arandr     sudo apt-get install arandr
  
  
-and open terminal and enter+Then open a terminal and enter:
  
     arandr     arandr
