Using IGPU and Dedicated GPU for multi monitor, corruption issue.

[Needles]

Hello all, sorry if this is not the correct thread (if not feel free to move mods), I have recently bought a second monitor and a the moment I don't have the right cable to connect both monitors to the graphics card (980ti).

I then remembered there is a setting in the BIOS of the motherboard to enable the igpu on my 6700k to use it for multi monitor. Having enabled this and downloading the correct drivers for it, multi display works.

Issues start appearing after awhile (30 mins to 1 hour), part of the screen starts to wobble, image cuts in and out and sometimes becomes completely corrupted.

CPU is overclocked (via XMP, 3200 mhz), is this the cause of the issue or is my igpu faulty?

May have figured it out, igpu needs to be set as primary in bios.

May have figured it out, igpu needs to be set as primary in bios.

So it's not possible to use the igpu for the secondary monitor and have your main GPU power the primary monitor?

I still have the primary monitor driven by the 980ti and the secondary on the igpu.

It is in the bios where the igpu is set to primary (as in first initialized).
