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?
I chose kde and 1920 1080
I’ve also used 180 hertz on windows so I know it’s a Linux problem
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
Desktop
Hdmi or displayport?
HDMI
Can you try DP? Or perhaps another HDMI cable?
Could try another hdmi but dp currently not yet
Please do, there’s a chance it may help
Okay will do
Let you know what happens
You can also try different inputs on your monitor if it has multiple HDMI ports
On my monitor HDMI port 1 has more bandwidth than 2
Welp I tried all my hdmi even in different ports too and nothing
Alright
I’ll get a display port soon and see how that goes
It should help, as it has higher bandwidth than most HDMI versions
True thanks for the help
What GPU and monitor do you have?
Rtx 3070 and a acer nitro
That goes up to 180 hertz
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

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 ...
Right, so it has dual HDMI 2.0 ports
So that means?
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
I am not sure but there is also a chance that it could be driver related. Nvidia support on bazzite is very fresh still
You could try to see if you’re able to hit 180hz at a lower resolution, such as 1280x720
If it does that, it’s probably an indicator that the your HDMI connection is somehow limited to 1 .4 speed
It won’t even let me change the hertz on 1280x720 it’s stuck at 60
Oh funky
That could be an EDID issue tho
This is very weird
That’s a HDR screen you have too, so that also uses some bandwidth if enabled
I have that disabled
Your max hz will be lower with HDR on than off
Alright
Has to be a driver issue
Possibly. I don’t have any experience with nvidia as I use AMD myself but it will be interesting to see if DP helps
For sure
I’ll see soon
So 144hz isn’t an option you can choose?
At 1080
That also goes black
Anything above 120 just doesn’t work
