Disappeared videocard parameters when boot from onboard video

[Fiber]

 I have a rig of 290X and everything is working grate when monitor connected to one of this cards. This card is just heating more than others, uses more memory etc.
So I decided to switch monitor to onboard video (Intel).
CGminer is working, but video parameters are not displayed (fan speed, temperature, clocks...). And also I cant set this parameters in CGminer (--gpu-fan, --gpu-powertune, --gpu-
engine, --gpu-memclock).

Any ideas how can it be fixed?
