the system is saying that my 22'' screen is 7'' and all the UI is very large to this screen

[Filipe]

the resolution is ok 1920x1080 but for some reason the system is recognizing my 22'' Toshiba TV display as a 7'' display and for that reason all the UI is extremely LARGE :P

Looks like its the same problem we have.

Try this in ur terminal:

$ xrandr --newmode "1920x1080" 173.00 1920 2048 2248 2576 1080 1083 1088 1120 -HSync +VSync

$ xrandr --addmode DFP1 "1920x1080"

u can change DFP1 for VGA1, etc...

@wishbon Unfortunately your hint didn't work for me. The problem still remains the same.

I have found a workaround to solve the problem which is propably caused by a bug in Gnome-3.

Qoute {

Here is command to execute in terminal as ordinary user (not root):

gsettings set org.gnome.desktop.interface scaling-factor 1
This command should immediately set some display elements to correct scaling, but to apply change for whole desktop you will have to logout and login. Set key can be read back with “get” option:

gsettings get org.gnome.desktop.interface scaling-factor

}
