Hi, All!
I can't set a fullhd resoulution on my second monitor. I don't see
1920x1080 in xrandr's output, so I used cvt to create a new one, but in
the end I got intel_crct errors in dmesg.
Here are some outputs.

Optimal resolution for my external monitor is 1920x1080 60Hz and I
definetely know that my VGA output support FullHD
