Multiple Monitors Are KILLING Your Gaming Performance! Here's How You Fix It 

I wasn't even looking for this answer! Was definitely having this issue and low and behold you popped up in my feed and saved the day!

Thanks alot for this tip! I quite frequently have video playing in the other monitor while i play, and i noticed that either my game would lag or the video would drop to 480p. Interestingly, i did not have this problem with my old PC. Recently upgraded from Gtx1060 into 6800xt, i7 4770k into R5 7600x....well anyway, this tip worked wonders.

I’d be careful doing this, depending on your CPU this could make things worse as this adds a significant load to your CPU to play video as it does it without any decoding help from the gpu

DUDE! Thanks so much! You got a new sub here. I've been having issues running my RX 5700 with dual monitors. If I game on one and have a video playing on the other my gpu clock would fluctuate from 0 to max gpu utilization would be all over the place. Turning off hardware acceleration seems to have fixed it!

Short, concise and helpful. Thanks :)

Short and sweet. Love it!!

Straight to the point, great video dude

Thankyou for the tip... disabling h/w accelerator in browser has helped a lot with extended monitor.

Omg, thank you so much, you solved my problem! I've been having this issue for a long time and could've never imagined it was the refresh rate that was causing it. I have a decent enough PC and this was so annoying.

Question: Were you making sure to use different browsers for the testufo site and the video?

Thank you for posting this video 🎉. You have a new subscriber. Keep up the great 👍 work..

Of all the tutorials and multiple tech channels in YT. You are the first one I see mentions the hardware acceleration. Thank you this fix all my issues with the micro stuttering.

Thank you, this helped me a ton!

I don't have performance issues, but my 2nd monitor recently started going black for a second - randomly. I turned off the hardware acceleration to see if that might help...idk

This is the same reason why I was thinking about just getting two of the exact same monitor since I'm in the market for a dual monitor setup.

That last minute decision for the led fans was definitely the way to go on that pc!

Make sure to go into settings on the PC itself and set your monitor refresh rates accordingly. I have x2 165hz and x1 240hz monitor. Never had any issues and i use one pc to game and stream at the same time with obs running and the stream and discord all running.

Does using power toys fancy zones with a single monitor LGCX 55 inch cause stuttering during streaming or recording to OBX?

G'day from Australia. Just stumbled across this video by accident, and thought it'd fix my stuttering issue while gaming. I use FireFox, and turned off Hardware Acceleration as you suggested, and UFO Test Refresh Rate shows it actually worse when I run something like a RU-vid video on my other monitor. Going to turn it back on and see what happens. My Monitors are a Phantom Gaming 165Hz 1440P 32" and a Phillips 75Hz 1080P 27". I've subbed to your channel, and looking forward to checking out some more of your videos.

good video! really well explained things

hi i really need help with my monitor so my main monitor started flickering black while i was playing fortnite and it stayed black my second monitor works perfectly fine and idk how to fix it

Just a quick tip, if you are turning off hardware acceleration this will put all the browsers load on your your CPU instead of your GPU if your CPU is better than your GPU then you can turn this on, if you CPU isn't very good I'd leave it check on.

thank you so much! i was hopeless, i just wanted to watch a movie while gaming and my main monitor started stuttering so thank you so much for this amazing tip

hi, if u dont mind me asking what mic are u using & other things u have to have ur mic setup. it has perfect sound quality. wanted to copy ur mic setup. thank you . :)

Thanks for the video. I have 2 240hz screen. Can i leave them both at 240hz and do not touch hardware acceleration?

I post this in a different comment, for OBS I have no idea if it works, but for browsers like edge if, put a folder open from the main monitor with a width of 3 or 4 pixels above / inside the secondary monitor, the browser will stop exploding, although there are times that even so it will do it.

i have 3 monitors 165hz 164hz and 144hz would it be best if I set them all to 120hz so they all match? would that help with performance? 2 of the monitors are 1080p one is 1440p.

Thanks bro 👍

When it comes to using a secondary display alongside a laptop, can you set the main laptop to use the main GPU and have the onboard Intel GPU handle the secondary monitor? If so how do you set that up?

Omg I will have to try this out! But I wonder what coses the issue exactly.

what if im not doing anything on the other monitors? can I solve this with a separate graphics cards for the additional monitors?

I switched to 240hz from 165hz .. and my performance drop while live streaming. Is there any setting I need to setup ? Just turn off the HW acceleration? P/s : only use one monitor setup and its 1080p

This is why for years I use two browsers. One for everything with hardware acceleration off as modern CPUs are far more capable these days of doing it all themselves. And in another browser with hardware acceleration on for when I need it

I have two monitors , cpu 12900K , gpu 3090Ti , should I connect two monitors to gpu or second which I need just for looking in chat (while streaming) I can connect to motherboard ( CPUs GPU) to have a best performance on my main monitor ?

i already disable HW acceleration in Chrome but the stuttering issue is still in there. But this issue is absent when using Microsoft Edge. It looks like Edge have better handling at GPU rather than Chrome.

Hello. I’m testing it right now on my main gaming pc but it’s picking up the hertz from the 60hz lol I’m I doing something wrong been dealing with this problem where my obs is lagging when using a elgato capture card I’d appreciate any help! Thank you

thank you soo much m you fixed my problem

Hello! I have 144 Hz and 60 Hz and sometimes (mostly when im gaming) my both displays just start flickering and pixsels are all over displays. Then i need to restart pc from behind to work again. Is there a fix for this. It also happens sometimes when im alt tab or chaning resolution

CAN SOME ONE HELP when i go into apex or any game it messes up my other windows like it makes them squished idk if its the resolution idk whats wrong pls hlp

That was a good one! Subscribed :)

Thanks i love when get perfect video like that

this still didnt fix it but im having the exact same issue. i cant find anything on it and i hate it. someone help pls

I have 2 240 hz monitors, when I use the ufo motion blur test it always pops up with the orange stutter message. Hardware acceleration is turned off, both monitors are set to 240 hz but I still get stutters, especially playing a game. Any idea?

THANK YOU BRO!!!!!!!! Was wondering my shit started lagging all of a sudden, and this fixed it!!!

Hey, since i also got that nzxt case - you can remove the two coolers in the front because they wont do anything at all :) inside that case only the two rear fans will make a difference because in the front the holes are placed badly and air would need to be pulled in at an angle to actually do smth :)

Is there any problem with RTX 4090 with two 240hz monitors?

I had this issue too, back 8 years ago.- then i found out about graphics plateauing. so basically multi-monitor users should mix monitors ONLY as multiplications. IE, 60hz+120hz, 60hz+240hz.. this will help to mitigate the issue SOMEWHAT. but then it's just microsoft programing issue.

Can you lock the secondary monitors' refresh rate to match whatever the primary monitor is and solve said issue?

wasn't having a problem but i was curious what turning off hardware acceleration would do, and it actually made me start to have stutters

What do you mean by disable preview window?

Started having problems after getting a 144hz 1440p side monitor in addition to my 120hz 1440p ultrawide. Does being ultra wide / aspect ration hurt performance as well? Can I cap my refresh rate on both monitors to 120hz to help them sync up? Kills me playing tarkov.

Very useful, Thanks , I have RTX 2060 8 GB, and I have two monitors the main one is Samsung odyssey G6 - 32 inch - 2K - 240 hertz and the 2nd one is LG 4K 60 hertz, I do heavy gaming and streaming and record games using elgato, my question is can I run dual monitor without any issues? I will use display port to G6 and HDMI for LG, please help, and Thanks for the video

I've been having an odd issue. While gaming on my main which is a 34" ultra wide and 24" on the side my screens will go black. I can make this happen if video on the side is at 1080. Upon checking the refresh rate which I thought they were both at 144hz, it turns out my second monitor has refresh rates that are a little off. So 144 is 143.855 and 120 is 119.982. Hopefully using this fix will stop the problems I've been having.

Oh boy my tv says it’s running at 30 what do I do? Help!

Does monitor technology affect too? My main is on fixed refresh but my 2nd monitor is on G-sync I have similar monitor (27 & 24.5) with same refresh rate

Nice. I use one 144hzas main and two 75Hz monitors. Never saw any problemsin ages

thank you so much for this info

Thank you my guy you the goat

mine says vsync failure how do i fix this

Im running 144hz 2k monitor and 1080 60hz. And im experiencing flicker on my 2k monitor this only happen when i added my 1080p monitor.

should i play with hdm1?

YES! This fixed my issue. Just added 2 more 1440p monitors to my 3080ti for a total of 3 and couldn't figure out why RU-vid full screened in 1440p was stuttering like CRAZY while my cpu/gpu/memory were all barely at 10% to 20% utilization with my temps very low! Big time appreciate the video! I knew about turning off hardware acceleration.... totally forgot to turn it off with a clean install of windows.... Thanks again!

thank you i never knew about hardware accelerations

I’m using 2 Neo G9s and an LG C3 for my monitors and having no issues here. But I’ll have to try these tips.

I have a question. What if both monitors are connected to different GPUs, like say, you’re using a laptop without a mux switch (one external monitor connected to dGPU, internal one hardwired to iGPU) or a desktop with two graphics cards

I run three monitors and have no issues. 4070 TI might be the difference? Who knows...

I have a 240 and a 165 and I saw a big fps drop for my 240 when using my 165 (which u mentioned in the video). Are there other ways to fix it other than just turning off hardware acceleration?

I love you Cyrus! I think it worked

can i use my 1st 160HZ monitor for gaming and 2nd 60HZ for YT or other application , will it affect gaming ?

sorry to say but not in my case at all. ive tested this with multi monitors on running vidoes ec and having them both off got me more stutter and hit the red once i put hard accel for both and also using chrome and opera gx. they both barely lost 4 -5 hz

I've been gaming on an Omen 25l computer and I have an XP pen 24 inch tablet also connected to the same gaming computer. I've noticed lately that my computer will crash during gameplay and will restart my computer even thought I have Auto restart turned off. Is it possible that my XP pen drawing tablet is causing the problem?

So if all of my monitors are 75Hz, then I'm just good?

Have you had this issue before?

Before ultrawide monitors were available I always run 3x identical screens and never had issues.

I have a question is it possible to match my two monitors hz by reducing the higher hz monitor to the lower via display settings? I'm using a 165hz and a 144hz

Anyone know what 2 monitors are those

I have a surface book on the side. Use that to watch RU-vid etc instead of plugging both my monitors into on pc

Is that still a thing with windows 11 ? are people all aware of this and removing hardware acceleration everywhere because I see alot of content creators with like 3-4 monitors sometimes with 60/144/165/240 all at the same time and they never mentionned anything about it. I tried the remove hardware acceleration thing it might be better but not perfect. Maybe one hdmi and one display port could be causing this both plug inside my gpu.

I am no expert, but in theory if ur GPU is bottlenecked by ur CPU this would make it even worse no?

i have two 60hz monitors, running a 3060. just added the second monitor but my monitor that i game on is dropping significantly in FPS. i usually average 130 but now im only getting 90. any recommendations?

My pc mouse starts lagging when I connect my second monitor main monitor: 1440p 144 Hz second monitor: 1080p 60 Overdrive 75hz It's not the browser it's the monitors or windows or my RTX 4070

I wonder if you can do this if your CPU is a KF variant which doesn’t have integrated graphics. Also, if you do this for Discord, does that mean when you stream on discord, it utilizes the CPU instead of GPU?

This whole time it was my monitors? And here I thought I had to upgrade my Ram from 16 to 32 to run obs and game at the same time. I even changed my fps limit setting on HELLDIVERS 2 to 60 fps, thinking that would fix the problem. And Subscribed!!!👍

Is there a way to do this with Opera GX? Whenever a video ends while I'm gaming, it causes the game to stutter and sometimes I get weird artifacting and I'm on a 3080..

For me, when I connect my laptop to my tv and only keep my tv screen on, only then the fps drops. How do I fix this

Since there are still people commenting here's a solution: You don't have to match 1:1, you only need to make sure main monitor hz is divisible by side monitor hz clean. I.E. New monitors at 240hz works with 60hz since 4*60hz=240hz so the gpu can update them together. If you have something like 144hz or 165hz + 60hz they will always be on different cycles and that seems to be the issue. Some games will stutter immensely unless you use bandaid solution and set your 165hz monitor down to 120hz so it matches with the old 60hz monitor. Then it runs perfectly fine. Weirdly this is not a universal issue and occurs only with some games. I personally tested this with the surge 2.

so i recently just got an elgato prompter and ever since i plugged it in i feel like my val games took a performance hit and my game doesn’t feel as smooth as it should be. HELP

I have the same setup one main monitor and a secondary one that is in portrait mode but when I move my mouse to the second one it is flipped aswell if that makes sence it behaves like it is not flipped at all what should I do

So I have an RTX 3070, and my main monitor is 244hz, 2nd is 60hz and now I added my samsung 60hZ 1080p TV. MY pixel drop rate is just -1 per second. FPS staying around 230-240. Is that something I should be like worrying about and adjusting somethings or just dont even worry about it. Sorry for being a bit ignorant.

hello i actually got a question what if i put 1 monitor into gpu and another one into motherboard to use cpu graphics?

So diffrent refresh rates matter, but do diffrent resolutions matter as well? I've got a 1080p rn and looking for a 1440p to go with it

You saved my life , thank you very much :) my animated overlays on obs were lagging as hell......i got my first 2k-165hz ips monitor , 5 days ago, and i use my old 60hz monitor as a "second" one, and i thought it was lack of ram, cpu, or even gpu. I was panicked :D Now the problems is better for 85%....maybe the rest 15% is hardware, probably i should upgrade my RAM (i have a ryzen 7 1700, 16gb ram on 2400mhz and a good old gtx 1070oc (not oc by me, its oc by default). :)

I have two monitors setup but unlike this video mine show the duplicate image. Will running things this way be of a concern? Thanks in advance guys.

Thank you for the excellent video! Do you happen to know if using multiple video cards mitigates this issue? If I run my games on a big card, and then run the 2nd and 3rd monitors, which are non-gaming, through another video card, does this resolve the issue as well?

Omg I totally forgot that 😮 I wonder if this is why I can’t drag anything that’s open over from my 2nd monitor namely a game keeps opening on my tv monitor but I can’t access it from my pc monitor its driving me mad! My pc monitor is 144 the tv is probably 60 and the windows settings are giving me a headache 😂

If you have a graphics card as well as integrated graphics, Is there a way to use integrated graphics gpu for browser acceleration instead? Would this fix stuttering?

Hello, i play on triple screen simracing ( 3 identical 240hz monitors ) plugged in displayport and use a fourth screen ( in reality a 60hz hd tv ) plugged in hdmi. The 4 screens are pluged into my rtx3090. I use the fourth screen to monitor obs and read the chat. As soon as i start a live i have this kind of fps loss. Sometimes they are real..i know the games i play are a lot demanding for my gpu..i can see the drop on the steam fps counter but sometimes fps are high and i have this feeling of fps drop. I changed my cpu because he seemed overloaded but now the new one is half utilized and i still have this kind of fps drop ( some call this stutter or microstutter ). So i did the modifications you said and i thank you for that. I did a test with UFO..Strange thing is that he always tells me potential browser stutter occurs while all my apps are closed, only UFO is opened in chrome. Other strange thing is that if i move the UFO window opened in chrome to my 60hz tv monitor..he still indicates 240hz..I hope the modifications will stop the stutters..Thanks again

unfortunately my second monitor is already the same refresh as my main 165hz. I will try these fixes though

I'm running a 4070 TI Super and a 3070 TI with each GPU hooked up to a monitor. Both monitors are the same (Nitro E12 curved monitor 2560x1440 165hz) but I was wondering if the 4070 TI super can support both monitors since they are both running 165hz? Google AI said the 4070 TI super can run 4 monitors (non-4k) and 2 4k / 8k monitors).

can't you just set both monitors to 144hz per say?
