Mob.1 mode never appears I have followed all the steps but I just can't do it
I tried instead done in this way and it is perfect the resolution is has 1920x1080p
in monitor I replace LCD Monitor and choose:
samsung syncmaster 20GLsi 1920x1080
then I choose:
1920p 50hz 56.25khz
then I go to screen
and it's perfect
everything works perfectly the monitor automatically configures the coordinates of the resolution.
but on reboot everything is as before
it's as if he hasn't memorized anything.
if you need I can make a video to explain myself better
thanks again for any help i really appreciate it.
I did not think I would encounter problems with the resolution of the monitor
