Is it wise to mix different refresh rate monitors on multiple display setups?

[Deleted member 209350]

I've seen a lot of varying reports on this. Some people say they can use a 60hz and 144z display in a dual screen setup and use each monitor fine, but there are others who are saying that the refresh rates mess up when mixing it together.

I ask this as currently I have 2 60hz monitors, but I want to add in a 3rd monitor thats 144hz for gaming use. Just not sure if it will actually work so was wondering if anyone on here has had similar experience

No issues at all here, running one 4k 60hz and another 1440P ultrawide at 120hz with gsync.

Have you ever had any issues with this, or at least heard of anyone else having this issue?

I'm 144Hz G-Sync on screen 1 and 60Hz on screen 2. My screen 1 ends up getting capped at 60hz if I run anything full screen on monitor 2. Cannot for the life of me fix it either.

This is what I was talking about!

For some reason it doesnt seem to affect everyone, but it certainly does happen which is making me question whether to bother getting a 144hz screen f its not even going to work properly

It's only really video content that does it. SLOBS is a main culprit. If I "just" have something like Discord open though it's fine. Just graphically accelerated stuff.

What if, for example:

plyaing game on 144hz monitor full screen, but on secondary 60hz monitor, just running a regular youtube video but NOT full screen?

Am I still going to see issues there?

The problem seems to be very hit and miss. I would say on my machine yes you'd see a problem as it is now. Some people say they have no problem and don't know what all the fuss is about. It is supposedly to do with how Windows 10 handles the displays.
A "cheap" way of fixing it is to pin your 144Hz display to 120Hz as apparently then it would come down but who buys a 144Hz to run it at 120Hz? <Although you probably wouldn't be able to tell.

Yeah ive also heard as 120hz is just double 120hz that it works better than 144hz.

I wish there was some detailed report somewhere explaining it in detail so I can get a better understanding

Me neither, but there obviously is some kind of maths/science behind this.

@Praz94 here's a turn up for the books. I tried a different game over the weekend and didn't have the problem of monitor 1's FPs capping to the same as monitor 2. Odd as the game is extremely more demanding but it behaved fine. Lots of variables and no way to give a straight answer.

Me and others report that mixed refresh rate monitor setups result in GPU memory locked at max speed constantly resulting in hotter idle gpu temps, posted this before but some people said it didn't on their system but the issue is known, I dunno if it effects newer GPU's but it does this on my 580

I guess all this thread has done is confuse me even more
