Hi guys,
Since the Nvidia Driver Update 378.49 and Windows 10 Update on 26 January 2017 (KB 3216755) my both screens are flickering on SLI and Fullscreen Games.
My Rig:
CPU: Inte i7-6800K
Cooler: Corsair H115i compact watercooler
RAM: 64 GB Ram 2400 Mhz Corsair
GPU: 2x MSI GTX 980Ti SLI
Mobo: MSI X99 Pro Gaming Carbon
Powersupply: Seasonic X-1050
SSD: Samsung 840 Evo
Monitor: Samsung 4K U24E590D and some random Samsung 1920x1080
Since the update when I start a game in fullscreen and SLI enabled the screen starts to flicker black and I get around 10-20 FPS. Here is a video for demo: [video="https://www.youtube.com/watch?v=OU-9p-g4BFc"][/video]
What I tried already:
Now the really strange thing
When I reduce the resolution on the 4K Monitor to 2560x1440 the flickering goes away it only happens on full resolution scaling. The strange thing is when I use for the game my second montior (1920x1080) and also the game in full scale on 1920x1080 the game also flickers. When I reduce there the resolution the game also stops flickering. For me thats something I call definitly a bug and not something to do with hardware besides cables. Before the GPU Driver update everything worked fine.
Now when I disable SLI and play the same game it works fine. I tested it with both cards and they are both healty and running good.
Maybe someone of you has a fix for this or could help me. I will appreciate any help

What I tried already:
1. Post on the NVIDIA Forum. Got some response but no fix. They say I should contact Microsoft.
2. Reinstall older NVIDIA Drivers with DDU and complete GPU Driver purge and reinstall. After the latest patch none older driver did work anymore and threw the same error. Maybe GPU Rom was overwritten??
3. Swap SLI Bridges with new ones and also replace Displayport 1.2 cables.
4. Tested the monitor with a other PC. Everything worked fine there. But this rig had still older drivers and not the Windows Update on it.
