When using my 4k Monitor my GPU clock shoots up to 1100 plus all the way up to 1400 sometimes when booting a web browser or steam. I've tested this with two different GTX 970 with Drivers updated. Same results one has higher clocks because it came at a higher factory overclock. My best guess is Nvidia hasn't paid much attention to drivers when concerning 4k displays. The cons of using cutting edge technology I guess. Any idea's how to fix the idle clock spikes. I could flashes the BIOS and GPU BIOS though I know very little about GPU BIOS.
