4K TV getting much higher FPS Than 4K Monitor

[dderek2018]

I'm using two Maxwell Titan X's in SLI. When using my 4K TV as a monitor using HDMI 2.0 my FPS are 20+ higher than when I connect my cpu to my 4K Gsync Monitor using displayport 1.4. Getting About 77-80fps in 4k on ultra settings on the TV when bench marking with Valley. When Using the monitor getting about 55-57 fps.

The display at the other end should have zero effect on how many frames the GPU can pump out. The only thing I can think of is that Gsync is somehow reducing FPS; you can try disabling it as a test to see if it has any impact.

Its really weird. I tried disabling Gsync and the results are the same. Its almost like the monitor is causing some kind of bottleneck. Which I think is impossible.

It should be; Windows, the game, and the GPU shouldn't care. Either there's a really odd driver problem with your display (and I can't imagine a TV driver is better then a Display driver), or there's some setting *somewhere* which is causing some Vsync like effect.
