 +===== Clean EFI Variables =====
 +
 +  * :!: Could potentially cause a firmware brick or other issues with improper EFI implementations, use at own risk ((personally tested fine on several Acer and Dell computers))

 +===== Custom Resolutions =====
 +
 +==== Generate Modeline ====
 +
 +  * Use ''--reduced'' only for LCD/Non-CRT displays, and only as-needed ((useful for reducing amount of bandwidth over cables, particularly in-case of unstable 4k@60Hz set-ups))
 +  * Syntax is ''horizontal'' (width), ''vertical'' (height) and ''refresh rate''
 +
 +  cvt '3840' '2160' '60'
 +
 +  cvt --reduced '3840' '2160' '60'
 +
 +<code>--reduced</code>
 +
 +==== Temporarily Apply ====
 +
 +  * Changes are lost after reboot
 +  * Values after ''--newmode'' are from the above generate command, and is everything after ''Modeline''
 +
 +  xrandr --newmode "3840x2160R"  533.00  3840 3888 3920 4000  2160 2163 2168 2222 +hsync -vsync

 +
 +  xrandr --verbose | grep *current
 +
 +==== Permanently Apply ====
 +
 +  * ''Identifier'' is the name of the port on the GPU the display is connected to
 +  * ''Modeline'' is from the above generate command, including the text ''Modeline''
 +  * ''PreferredMode'' is the custom resolution name generated
 +
 +<code>
 +Section "Monitor"
 +    Identifier  "HDMI-A-0"
 +    Modeline x
