Problem with displaying 240hz

[Bogdyoda]

Hello, I have purchased a new monitor which had just arrived today with a refresh rate of 240hz and a resolution of 1440p. I have had a couple of issues with it and I would like to know whether my PC or monitor is at fault here or if any of these are broken. First of all, i would like to point out that both my PC and monitor are new(self self-built PC is a couple of weeks old and the monitor is brand new). I have done all the needed settings to have my monitor display 240hz and it works for a while but after a while (shorter or longer) my display just goes back to 60hz, while set in-game and on Windows at 240hz and a screen tear appears, just this one horizontal line tearing my screen. I am using an Rx 7900xt card(AMD), so there are no settings that should be done from amd adrenaline settings, especially since it clearly works at 240hz for a while. Now while I am in that broken state where my display shows 60hz only and my screen is tearing what I have noticed is that when I change my refresh rate from 240hz to 120hz my screen tear goes away but the display is still stuck at 60hz. I have been working on this issue for a whole day and what i have tried was updating my GPU driver, reinstalling them, changing the display driver, and tweaking the settings on the monitor. Once it goes into that broken state, it sometimes goes back to normal, but after that, it would again break down and stay broken. I have also tried three DP cables, including the one sent with the monitor. One interesting thing that is happening is when the monitor goes into this broken state the menu on the monitor is working slower. Any help would be much appreciated!

you can try creating a custom resolution in the driver and using that(?)

Hi thank you for the response! Are you talking about creating a custom resolution in AMD Adrenaline?

I believe they are, yes

You could tru reinstalling your graphics drivers, and if that fails I would look at returning the monitor

Thanks for helping out, I have tried doing that and the process has been bizarre to say the least. A lot of times it would display errors and other times it would work partially, meaning it would never allow me to set it any higher than 200 hz, but even at 200 hz the display is still stuck at 60hz and the screen tears. At this point I am considering returning the monitor.

If you are looking to return the monitor, id recommend getting one with AMD freesync, which should help with the screen tearing issue in future, that is if this one doesnt already have freesync

Try setting a driver-side fps limit at 237 fps. Sometimes games can fluctuate a bit, so even if it should run at 240 fps, it can go slightly faster, going over the VRR range and effectively disabling VRR. The fps cap will alleviate that possibility.

 

If that doesn't work, your monitor is probably faulty. Samsung is known for it's constant monitor firmware issues. I wouldn't be surprised.

I will try that, what I have tried so far is capping the fps in-game which didnt lead to any improvement but i havent done it from the drivers yet so I will look into that.Thx for the suggestion, I will let you know whether that helped.

This one does have AMD freesync and it is recognized by the monitor and running. Thank you for the suggestion though.
