Graphics Issue Help

[mikencha]

So My rig right now is: 

-I7 8700k

-Nvidia GTX 1070 FE

-16gb mixed ram

-1tb samsung 860 Evo

-1tb WD Blue

-main monitor: Benq XL2420Z 1080p 144hz

-secondary monitor: Samsung U28E510 4k 60hz

So my issue is, everytime I play a game on my main monitor and something moves on my secondary monitor my game has lag issues. It feels like the frames are dipping below 60fps but the thing is, fraps and the in game fps counter is showing well above 144 frames consistently. This doesn't happen if my 4k monitor is static but if even the slightest thing moves on my 4k monitor, the game lags. Please help I have no idea what the issue is. I tried putting a different graphics card in there and even tried seeing if my cables are messed up and nothing solved it.

So you game on the small monitor for fps but leave the big monitor on as a single desktop, and as soon as anything moves on the big 4K monitor which you don’t game on because it doesn’t have the FPS your game lags because all of a sudden you’re trying to push 4K.

 

have you tried simply shutting off the big monitor when you game?  That would reduce your desktop size.

thats the thing though, Im getting consistent frame rates on my monitor and this doesn't happen when my 4k monitor is static and if we are just looking at fps, I shouldnt be getting any lag at all. It always hovers around 180 frames

Well yes it wouldn’t happen.  The GPU isn’t drawing frames for your big monitor are all when it’s static.  You put anything ON the big monitor though and it has to draw frames so it switches gears and does what it’s told.

OK so is there no way to get this to work?

I still haven’t been told what “this” is.  I just offered the simplest solution to the problem you offered.

but also the problem is, it happens when i'm playing a lower res video too. It also happens when I start the game with the video already playing. So if it is because the sudden demand for 4k is making me lag on my first monitor then that shouldn't effect it right?

Shouldn’t affect the small monitor?  No, i think it would still do that.  I wrote a bit explanation of why I though so and then erased it.  I wasn’t sure it was true.  I can give you only what I got. Which is old, dusty, and of questionable value.  There may be better ways to do this. Ones that may get you what you want.  I do think this will work though:

 if you want to play a game so resource intensive that your 4K won’t work for it and you have to do it on your 1080p monitor, turn off your 4K.  Is it the best solution? Very possibly not.  I’m just saying I think it will work.
