How to make your resolution on second monitor on Ubuntu 16?

Question

linux

I connected the second monitor (4:3) to the computer via VGA,
the first monitor (16:3) via DVI is set
. The resolutions of the first monitor are set up perfectly,
but the square one has a maximum resolution of 1152x864, how can I do more?
Monitor 19", everything floats a little.

Answer 1

The last three commands in starup or .xinputrc if without DM launch
Example for 20" 16:9.
4:3 calculate with calculator.

gtf 1920 1080 60 -x # Определяем ModeLine
xrandr --newmode "1920x1080_60.00"  172.80  1920 2040 2248 2576  1080 1081 1084 1118  -HSync +Vsync # Устанавливаем согласно выхлопа gtf(Будет, разумеется,  наверняка другой)
xrandr --addmode VGA1 1920x1080_60.00 # Добавляем
xrandr --output VGA1 --mode 1920x1080_60.00 # Активируем

Answer 2

Perhaps your VGA cable does not support the DDC (Display Data Channel) digital bus, through which the video card receives its name and list of modes from the monitor. Try to replace it.
And you didn't write the model of the 19" monitor. What resolutions does it support?
