Playing video on my second monitor makes my 144hz monitor lag.

Whenever I play video on my 60hz Second monitor the first one starts to lag and become choppy in games. If I minimize the video but keep it running it fixes it so its not performance I don't believe.

And ive plugged the 2nd monitor into my gpu instead of the mobo and its still the same.

 

What can I do to fix this thanks.

i don't know why it does it when you have it plug in to the gpu but having the 2nd monitor plug in to the mobo will play the game on your cpu's interrogated graphics and not you gpu

This happens to me as well. If I play a video on the second screen, my game's fps would drop. If I play my game while the video plays, the video fps drops.

I don't think there's a way arounf this unless you switch off hardware acceleration. Never done it before tho so I don't know if it'll work.

set you refresh rate to 60hz on both monitors, probably won't work but try it

I think one with 60hz ond other with 120hz will work fine.

It was the same.

From what I've researched so far, if your desktop is not a surround desktop, the gpu will render only on the screen that has your active application on.

So when you click on your video in the second screen, it gives priority to the second screen and your game's framerates drop and vice versa.

I could be wrong tho. I hope I am because I want smooth video playback and high game fps too.

I play games on my 144Hz panel and play videos on my 60Hz panel at the same time - no issues.

do you have them both plugged into the gpu, nvidia/amd?

That's weird.

 

How do you guys do it? I always get framerate drops when I switch my active application. And both my screens are 60Hz too.

It's cause you basically "alt-tab" out.. Solution might be configuring both displays as one and gaming in windowed frameless..

I think it has something to do with windows/directX just not being able to run a high framerate window along with any more than a few other simple windows like afterburner or something else with not much movement. Chrome seems to especially tank your FPS, even with just a static image up. The best solution I found was just to suck it up and minimize most of my other windows.

The only solution I've found that works is to run games (whenever possible) in borderless window mode.

Have you found a solution for this? I'm having the same issue. FPS stays the same on the 144hz monitor but is laggy when a video/livestream is on the 60hz monitor.

You've tried disabling Hardware acceleration right? That worked for my google chrome but not for my Vivaldi browser, as Vivaldi seems to lag on the lower refresh monitor regardless of what I do. If your using an Nvidia card you can also try setting multi-display/mixed display acceleration and see if that does anything (I have no idea what it really does). On my other setup with 2 R9 390 I couldn't find a work around for the lag so I just had to deal with it or just close the browser, maybe it's just how the way AMD handles multimonitor or maybe there is a setting and I just couldn't find it.
