Acer Predator XB281HK , gsync on , still some tearing

[kanva90]

Hi , I bought a new acer predator Xb281hk, it's a 4k 60hz monitor , I m using gsync yet I can notice some tearing while playing doom 2016, tried with gsync and vsync on , vsync off , gsync on , still tearing occurs, its minute but I expected with gsync it's absolutely no screen tearing , also whenever I change resolution to 1440p , there is a keyboard input lag, mouse works fine, tried enabling and disabling filter keys still have to always restart or log out and log in to computer for removal of input lag, if someone could help it would be greatly appreciated

In a few weeks the new 144 Hz 4k predators (AcerPredator XB272-HDR) will drop .... If still within the return period, I'd send it back and wait for the new models.

As to your question, what's driving the monitors card wise ?

Using a gtx 1070, i5 6600k , 16gb ram

Even the 1080 Ti can't maintain > 60 fps in all of today's games at that resolution. We recommend:

4K @ 144 Hz - 1080 Ti in SLI
1440p 165 Hz - 1070

Start here to see what you can expect at 4k in various games:

Most are in the 25 - 45 fps range. Only one game (WoW) breaks 60 fps at 4k w/ a 1070

Gta5 very high settings , battlefield 1 dx11 medium settings , doom 2016 high settings, all work at 60fps at 4k , my issue is input lag that comes along with vsync , isn't there a way to play without vsync and switch on gsync only and not get screen tears ?

There is also this issue , whenever I change any game resolution to 1440p or 1080p , keyboard input lag starts, if I plainly run at 4k without changing resolution no input lag, even if i revert to 4k from a lower resolution it's starts lagging
