How i can add a resolution in Zorin what don't appear me

i don't know what do help:(

You can use the terminal command


to list your Monitors. It might look like HDMI1 or DP1...
This depends on if your monitor is comnnected via HDMI or Display port or VGA...
If it is a Notebook computer with built in screen, it may look like edp1
Once you have that Identifier for your monitor, you can use the xrandr -- newmode and --add mode commands to add a custom resolution. Set the parameters as you want them to be... but you can check if your monitor supports your desired resolution (pixels by pixels and then hz or Refresh Rate):

cvt 1920 1080 60

here is an example you can use as a template. Let's say your display is HDMI-1:

sudo xrandr --newmode "1920x1080_60.00" 173.00 1920 2048 2248 2576 1080 1088 1120 -hsync +vsync

sudo xrandr --addmode HDMI1 "1920x1080_60.00"

You can also set the mode with xrandr:

xrandr -s "1920x1080_60.00"
