Default multi monitor setup problem?

So, my motherboard has two graphic-outputs: one is HDMI, other is VGA.
I connected 1680x1050 monitor to my HDMI slot.
And another 1280x1024 monitor to my VGA slot.

I started my computer, and OpenBSD started, but my higher res monitor shows 1280x1024 resolution (resolution of my lower res monitor).
And I see the same image on both of my monitors.

I want to set native resolution on my 1680x1050 monitor. And have different displays on both.

xrandr -q
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 640 x 480, current 1280 x 1024, maximum 1280 x 1024
default connected 1280x1024+0+0 0mm x 0mm
   1280x1024      0.00*
   1024x768       0.00
   800x600        0.00
   640x480        0.00
Basically useless.
Not sure how to tackle this?

What you've posted so far is that xrandr(1) is only aware of one display device. More information could possibly be helpful:
  • Your dmesg(8)
  • Your /var/log/Xorg.0.log file
