1280x800 resolution on Intel BayTrail minipc

Hello,

I'm trying to set native resolution when viewing on my BenQ MW516 projector.

Initially it starts with 1920x1080 resolution and does not have 1280x800 in its settings.

After trying this:

Code

xrandr --newmode "1280x800_75.00"  106.50  1280 1360 1488 1696  800 803 809 838 -hsync +vsync
xrandr --addmode eDP1 "1280x800_75.00"

I can set this resolution, but the projector says the resolution it gets from pc is 1280x1024, and the optimal is 1280x800.

This trick previously worked on my other PCs, with intel or nvidia GPUs. How to make it work on this minipc?

I do not know, why it says eDP1, because the projector is connected to its VGA output.
