Solved: IntelHD Screen Flicker under DX11 FullHD!

[AscheWandler]

I had the Problem with my P150SM (GTX770M) ´, that on various Games (ex. Homefront, both Metro Games, GTA5) under FullHD the screen flickers.

But only under DX11 and FullHD. Other Resolutions or the switch to DX10 runs everything fine!

The Problem most (me too) people had is an issue of the Intel HD graphics card switches 60p Hz in FullHD DX11 gaming back to 60i Hz on an external Screen.

That causes the screen flickers and made gaming annoying.

Searching the net made the most hits like "install newest driver" or "switch back to the driver of the brand" (Clevo in my case). Tried all of these suggestions but nothing worked.

The solution is (in my case) very simpel at all: (made with Driver 10.18.15.4256 (17.07.2015))

1. go to the Intel graphics options

2. under "Display" you can find "user defined Resolution"

3. Warning appears "changes can cause crashes" ect.

4. there you can choose between "internal Display" or the external (S273HL in my Case)

5. put the 1920x1080 60p in both Displays and "add" them to the List.

My Screen goes for 2sec. black and after it was back on every game works fine in FullHD with DX11!
