Lower Sol/s when card is disconnected from monitor.

I currently have a 6 gtx 1070 mining rig mining Zclassic fulltime. I have configured TightVNC so I can see the screen of the miner without having a monitor connected to the gpu.

However, I can get around 470 sols from the card connected to the monitor via DVI. When I disconnect the monitor and look at the screen from the TightVNC viewer(wich is basically like teamviewer), the sol/s tank to like 300…

Is there anyway I can stop this?

you still need to setup onboard graphics and NOT use the gpu… since the computer is still “using” the gpu when you look at it via whatever program that is…
