refresh rate wont go over 120

I tried many times to change my refresh rate to 180 hertz but it gives me a blank screen for 30 seconds every time i change it is it any fix to this?

On what type of system at what resolution?

dinoOP•1/27/25, 5:56 AM

I chose kde and 1920 1080

dinoOP•1/27/25, 5:57 AM

I’ve also used 180 hertz on windows so I know it’s a Linux problem

mefLL•2/1/25, 2:45 PM

there's a chance that windows is using chroma subsampling 4:2:0 or DSC to slightly lower the image quality and make more bandwidth for higher refresh rate though, if you're being limited by the type of cable you're using

can you provide info about what type of system you are using? like, a handheld, laptop, desktop PC, and how it's connected to your screen. what cable, through any dock/adapter, etc

Hdmi or displayport?

MmefLL Hdmi or displayport?

dinoOP•2/1/25, 6:12 PM

HDMI

mefLL•2/1/25, 6:12 PM

Can you try DP? Or perhaps another HDMI cable?

dinoOP•2/1/25, 6:14 PM

Could try another hdmi but dp currently not yet

mefLL•2/1/25, 6:15 PM

Please do, there’s a chance it may help

dinoOP•2/1/25, 6:15 PM

Okay will do

dinoOP•2/1/25, 6:15 PM

Let you know what happens

mefLL•2/1/25, 6:16 PM

You can also try different inputs on your monitor if it has multiple HDMI ports

mefLL•2/1/25, 6:16 PM

On my monitor HDMI port 1 has more bandwidth than 2

MmefLL On my monitor HDMI port 1 has more bandwidth than 2

dinoOP•2/1/25, 6:25 PM

Welp I tried all my hdmi even in different ports too and nothing

mefLL•2/1/25, 6:26 PM

Alright

dinoOP•2/1/25, 6:26 PM

I’ll get a display port soon and see how that goes

mefLL•2/1/25, 6:26 PM

It should help, as it has higher bandwidth than most HDMI versions

dinoOP•2/1/25, 6:27 PM

True thanks for the help

mefLL•2/1/25, 6:27 PM

What GPU and monitor do you have?

dinoOP•2/1/25, 6:28 PM

Rtx 3070 and a acer nitro

dinoOP•2/1/25, 6:28 PM

That goes up to 180 hertz

mefLL•2/1/25, 6:29 PM

I see. If you can find the exact monitor model number on the sticker of the back of the monitor I can investigate how much bandwidth it should be able to support on each port

dinoOP•2/1/25, 6:30 PM

Found it right here https://www.amazon.com/dp/B0CJQ95GW3/ref=tsm_1_tp_tc

In competitive gaming, every frame matters. Introducing Acer's KG251Q gaming monitor - the Full HD (1920 x 1080) resolution monitor that can keep up with your game play. Through AMD FreeSync Premium technology, the game’s frame rate is determined by your graphics card, not the fixed refresh rate ...

mefLL•2/1/25, 6:32 PM

Right, so it has dual HDMI 2.0 ports

dinoOP•2/1/25, 6:33 PM

So that means?

mefLL•2/1/25, 6:34 PM

That should support up to 246hz at 1920x1080. But if anything drops it down to HDMI 1.4 (such an the cable being old or bad, or any type of adapter/splitter/HDMI switch you may have between the GPU and the screen) then the refresh rate will not go higher than 146hz without DSC or chroma subsampling

mefLL•2/1/25, 6:35 PM

I am not sure but there is also a chance that it could be driver related. Nvidia support on bazzite is very fresh still

mefLL•2/1/25, 6:35 PM

You could try to see if you’re able to hit 180hz at a lower resolution, such as 1280x720

mefLL•2/1/25, 6:36 PM

If it does that, it’s probably an indicator that the your HDMI connection is somehow limited to 1 .4 speed

dinoOP•2/1/25, 6:38 PM

It won’t even let me change the hertz on 1280x720 it’s stuck at 60

mefLL•2/1/25, 6:39 PM

Oh funky

mefLL•2/1/25, 6:39 PM

That could be an EDID issue tho

dinoOP•2/1/25, 6:41 PM

This is very weird

mefLL•2/1/25, 6:41 PM

That’s a HDR screen you have too, so that also uses some bandwidth if enabled

dinoOP•2/1/25, 6:41 PM

I have that disabled

mefLL•2/1/25, 6:41 PM

Your max hz will be lower with HDR on than off

mefLL•2/1/25, 6:41 PM

Alright

dinoOP•2/1/25, 6:42 PM

Has to be a driver issue

mefLL•2/1/25, 6:42 PM

Possibly. I don’t have any experience with nvidia as I use AMD myself but it will be interesting to see if DP helps

dinoOP•2/1/25, 6:43 PM

For sure

dinoOP•2/1/25, 6:43 PM

I’ll see soon

mefLL•2/1/25, 6:43 PM

So 144hz isn’t an option you can choose?

mefLL•2/1/25, 6:43 PM

At 1080

dinoOP•2/1/25, 6:44 PM

That also goes black

dinoOP•2/1/25, 6:44 PM

Anything above 120 just doesn’t work

Ddino Anything above 120 just doesn’t work

mefLL•2/12/25, 7:59 AM

How did it go? Did you try with DP yet?

MmefLL How did it go? Did you try with DP yet?

dinoOP•2/12/25, 10:39 PM

Yep just got delivered today and surprisingly that was actually the problem

dinoOP•2/12/25, 10:39 PM

The display port works

mefLL•2/12/25, 10:39 PM

ohh, so now you can run it at full hz huh?

refresh rate wont go over 120
