New Monitor Question

[Dudejoss]

hi,

I've been looking at getting a new monitor but i've been reading online that if you have multi-display and both are not the same hz it will drop the faster monitor.

eg. if you have 144hz screen but you have something on your 60hz side monitor it drops both down to 60hz is this true or do you guys know any way around it other then buying multiple 144hz screens?

Thanks

josh

It's not true. Atleast not in my experience.

What is true however is that mixing refresh rates causes your GPU to run its memory at max clock constantly. Normally it would downclock when idle. It's a bit annoying considering it causes higher temps, more power and thus more noise when idle.

oh okay i read this about windows 10 and something to do with the aero and windows interferes with it.

i dont know about other other OS's

here is a link to the issue i have read about

I've currently got 3 monitors up and running, one of which is 144hz and two are 60 hz. I never experience any hz issues. I game on the 144hz and it's working brilliantly, and I've not noticed any problem with my GPU running at max clock constantly either, it goes up and down as it normally does, depending on the workload required. My GPU's idle temp is between 38c - 44c, while under load (depending on what I'm playing or doing) it goes between 70c and 85c.

Might be a Nvidia issue then, I've never noticed such a thing with my setup.

Look only at the GPU memory clock, the core clock isn't affected. I see in your signature you have an RX 580 which is very similar to my RX 480. It should have an idle memory clock of 300Mhz whenever you're not gaming or decoding high resolution video or something similar. My memory clock however is at 2000Mhz constantly, i.e max clock. This is with 1 144hz and 1 60hz screen. With my previous 2 60hz screens it did idle down to 300Mhz.

maybe this might be a NVidia issue i noticed the posts are from a while ago so i was wondering if anyone has seen this with a NVidia card?

Nvidia had some problems with monitors of different refresh rates and monitors with very high rates (144-165hz) on older drivers (~2014?), I think it's fixed now?

Afaik, overclocked monitor refresh rates (either by manually created custom resolutions in Nvidia panel OR some panel gimmicks from some manufacturers) prevent the gpu from downclocking on Nvidia cards (AMD cards downclock just fine). Don't think there's a workaround, I've read it's hard-coded in drivers.

So this issue should now be fixed I just don’t want to get a 144hz monitor then playing twitch or someone on one of my older monitors to cap at 60hz
