Native resolution problem

When I connect monitor to onboard VGA it doesn't work properly, can not set it on NATIVE RESOLUTION, it shows many other resolutions.

I can only set it on Native resolution when I connect monitor to GPU, GPU sees the correct resolution but onboard graphics doesn't.

What can be the problem here? 

The GPU somehow manages to use native res but onboard graphics doesn't while other monitors work properly on onboard VGA....

When you're connected to your onboard video, do you see Windows Basic Display Adapter in Device Manager? If so, you don't have drivers installed for your onboard graphics.

It doesn't work with or without drivers, but works good on other monitors.

This monitor has some problem with onboard VGA but it works properly on GPU...
