Display minimized, wrong max resolution

I’m trying to install Xubuntu on my GOT3177T-834, but I have some display/driver issues.

I see that my max resolution is 1280×1024 and I want to it, but resolution list has max resolution 1024×768. So, I tried to:

cvt 1280 x 1024 60
sudo xrandr --newmode "1280x1024_60.00"  109.00  1280 1368 1496 1712  1024 1027 1034 1063 -hsync +vsync
sudo xrandr --addmode eDP-1 1280x1024_60.00

When I apply this setting, the display has a worst view:

My video card is an intel, so I also installed mesa-utils, but same problem.

What can I do? The monitor is unknown.

Thank you!
