Storage HDMI out -> DVI-D set resolution to 1280x1024 from 1280720

I am using Measy U2A Dual-core Mini PC dongle with original Android 4.1 and Compaq 1720 monitor which offers 1280x1024 resolution. I am using a HDMI to DVI-D passive converter to connect the monitor. I do get 1280x720 resolution so the screen look like stretched vertically.
Is there any easy way to change the resolution to 1280x1024 which will make it more appropriate?
I tried changing in the Screen -> HDMI Mode -> 1280x720P but there is no option for 1280x1024.
