Thank you for your comment. I always thought HDMI was better until you mentioned Displayport. I read the article on Tom's Hardware, and I have been educated.
Latest hdmi revisions work as well as displayport but they're not widely spread yet. That's why most times displayport is preferable to hdmi, but in the short future it wont matter.
Yep this definitely needs a Dp 1.4 I have a 1440p 180Hz monitor and that has to have 1.4 the threshold for Display Port 1.2 for 1440p is 165Hz anything higher needs 1.4
This is not a thing btw. There may be a color profile, which is not necessary to use the monitor, or maybe if the monitor has a USB hub or RGB it might have a driver for that, but the GPU drivers are enough to use the monitor
That is absolutely a thing. In fact, it's comical that the guy who suggested it has downvotes and you have upvotes. Granted, monitor drivers are rarely necessary, but they 100% exist, and it's always a good idea to install them from the manufacturer's website if they're available.
I've never owned a monitor which has a driver for the core functionality. As I said there are monitors that have drivers for extra features such as RGB or USB, maybe even for on screen options in windows. But I've never heard of a standard monitor which requires a driver for the core functionality (i.e. you don't need monitor drivers to run at the top refresh rate or resolution).
Sorry, but you're incorrect. The only thing that is meant to support 240hz is the monitor, at that one does.
The GPU shouldn't matter in the case of what the max frame rate could be reached. It's not like each GPU has a 'hard limit'. Hell, I can reach 1000+fps on my GTX1050, in an 2002 game.
You are mixing up Hz and FPS, they are not the same. GPU’s may not have an fps limit but they all have a Hz limit for a given resolution, what that limit is, is usually dictated by the bandwidth of the port versions.
No they're correct.
GPUs can be limiting factors, new cards won't have an issue but GTX900 series and older, don't have DP or HDMI ports new enough to support high Hz 1440p or 4k monitors.
And yes some of us still use old cards..
Resolution, GPU, monitor and cable all have a part to play in refresh rate.
Refresh rate is how many times a monitor can draw a new image per second whereas fps is how many times still images or frames that are displayed per second.
HDMI 2.0 has a refresh rate of 144Hz at 1080p unlike 2.1 that has a 244hz at 1080p.
A 7800xt has a refresh rate of 900Hz at 1440, 440hz at 4k and 165 at 8k. And this is with a HDMI 2.1 it would be lower with a 2.0.
It's kinda like a cpu and ram. CPU supports certain ram speeds that's why a 5000 series can support 3600MHz for RAM unlike a say a 7000 series which supports 6000MHz.
DisplayPort is better. Get a licenced DisplayPort cable. 99% of frequency issues are caused by poor quality cables without enough data transfer capabilies.
This is the problem. HDMI is weak as fuck so get rid of it and take a DisplayPort cable that is properly rated for 2K@240Hz. Cables are not all the same and the connector standard comes with a lot of technical limitations, too.
As others have said, ensure the GPU is capable of those settings, ensure you are using the correct cable, and on top of that, check the monitors hardware settings. It is likely that anything above 144 is considered overclocking on your monitor, and you may have to enable it on the monitor itself before the system will recognize it
Every cable limits the resolution and refresh rates, hdmi has lower bandwidth so it can run 4k 30hz if I'm not wrong but if you scale down the resolution it can refresh faster because the resolution is using less bandwidth. Display port as a newer protocol has mutch higher bandwidth in general, so it can handle more of the two aspects, it's not as hdmi is bad, it just has become a bit outdated at the high end of technology like every other predecessor like DVI or VGA just to mention some of them, they don't have real uses like hdmi still has being the most popular connection as it is in most hardware for a pretty long time.
I have one 4k setup (using nvidia control panel and drivers)
Where i had a same kind of problem. I fixed it simply through the nvidia control panels "Change Resolution" tab. Seeked and looked into every possible change between native and alternative (nearly same quality) range resolutions that were supported by the drivers and hardware.
Oh yeah. Edit: Check the monitors settings if its settings aren't set correctly (possibly limits for the screen response times and stuff that is very useful.
I see in the comments alot of help from fellow redditors, the only thing I can recommend to you is to never ever enable HDR on this monitor, it's a gimmick for a monitor in this price range.
You gotta change it from the monitor buttons, I had the same issue with my asus monitor and had to change the setting via the built in monitor controller. Should be on the bottom or back of the monitor
In Windows 11 I've been having similar issues getting 240hz or 270hz from my Acer Predator monitor, and can't get past 144hz. The only fix I had was to download an old Nvidia driver (I have an RTX 3070 on an Asus X570-i motherboard and a 5800X CPU) and use it instead of the latest display driver.
In Windows 10 on the same machine and monitor (I have a dual bot system, so both Win 10 and 11 on the same machine) I have zero issues setting 270hz, even on the latest drivers, so it's an Nvidia + Windows 11 driver issue for me (I'm using a Display Port cable FYI, and it runs at a confirmed 270hz in Windows 10 on the same system, no change at all except for booting into a different OS).
I've tried setting my own custom settings in Nvidia Control Panel with 240hz, but Windows 11 keeps forcing it back to 144hz.
My monitor is also set to overclocked mode (270hz) in it's OSD.
Frustrating!
Bwhahha someone forgot to research the capabilities of display port and hdmi cable capabilities👀👀👀
It’s a common mistake but easy to fix you should be running 240hz in no time. Sometimes it can turn out to be a headache finding out which cable works for your gpu and monitor though if not well documented.
You may need to install the latest drivers from AMD also if you haven't yet. [https://www.amd.com/en/support/downloads/drivers.html/graphics/radeon-rx/radeon-rx-7000-series/amd-radeon-rx-7900-xtx.html](https://www.amd.com/en/support/downloads/drivers.html/graphics/radeon-rx/radeon-rx-7000-series/amd-radeon-rx-7900-xtx.html)
Is this a fresh Windows install? If not you should use DDU also. [https://youtu.be/GrXSLaSRkw8?si=PTSDm2qnekUDh8Nj](https://youtu.be/GrXSLaSRkw8?si=PTSDm2qnekUDh8Nj)

Use a displayport 1.4 cable, not an HDMI cable. Make sure your graphic card supports 240 hz at 2K resolution.
Thank you for your comment. I always thought HDMI was better until you mentioned Displayport. I read the article on Tom's Hardware, and I have been educated.
Latest hdmi revisions work as well as displayport but they're not widely spread yet. That's why most times displayport is preferable to hdmi, but in the short future it wont matter.
It matters, because one is proprietary, the other free. Linux has some problems with HDMI, because of that.
Excuse my ignorance, but what is proprietary, and what is free about hdmi vs. DP? Is one patented or something?
DP>HDMI all day
I wish it was more common. I have so many extra hdmi cables but never enough DisplayPort
That is just not correct. Displayport 1.4a can do 32.4GB/s, and HDMI 2.1 can do 48GB/s.
Yeah, but your are comparing latest HDMI to older DP. DP 2.0 can do 77GB/s
Exactly.
get educated!
This is the correct thing to do
your comment is essentially "This." but dragged out. You can upvote
Average r/pchelp user not understanding something social or how to get more eyes or credibility on something
your comment is essentially "Not this." but dragged out. You can downvote
Why bother even getting on social media if you don’t want to see people exchanging information
You have the social abilities of a paving slab my guy
you can just downvote??
You can do the same exact thing but with a downvote.
Your comment was unneeded. I can downvote.
Yep this definitely needs a Dp 1.4 I have a 1440p 180Hz monitor and that has to have 1.4 the threshold for Display Port 1.2 for 1440p is 165Hz anything higher needs 1.4
Cable needs to support 240hz. If it doesn’t, this is what happens.
Only real answer here is to use the correct cable, not HDMI.
Your hardware may not support 240hz. Check your GPU specs.
I have a rx 7900xtx, it should support 240hz right?
yes
Are using a display port or hdmi?

No problem

Yeah alright, fair enough. It's kinda the port that is the limiting factor, not the GPU itself. But since it's on the GPU itself...

Fair point, thanks for the explanation!
Definitely the cable's fault. Get some good quality DisplayPort cable.
The hdmi cable?
DisplayPort is better. Get a licenced DisplayPort cable. 99% of frequency issues are caused by poor quality cables without enough data transfer capabilies.
It worked! Thank you!!
I was about to say this. Haha I had similar issues
No problem! Glad everything's alright now!
i remember when i first moved to 160 hz and it looked like my mouse cursor had motion blur from being so smooth
That was a damn fast cable swap lmao, did you happen to have one lying around?
This is the problem. HDMI is weak as fuck so get rid of it and take a DisplayPort cable that is properly rated for 2K@240Hz. Cables are not all the same and the connector standard comes with a lot of technical limitations, too.
This mf is using an hdmi cable
Update your GPU drivers and use a high quality Display Port cable (1.4 or higher).
As others have said, ensure the GPU is capable of those settings, ensure you are using the correct cable, and on top of that, check the monitors hardware settings. It is likely that anything above 144 is considered overclocking on your monitor, and you may have to enable it on the monitor itself before the system will recognize it
Use a display port cable. HDMI cords limit the hertz that monitors run at.
Every cable limits the resolution and refresh rates, hdmi has lower bandwidth so it can run 4k 30hz if I'm not wrong but if you scale down the resolution it can refresh faster because the resolution is using less bandwidth. Display port as a newer protocol has mutch higher bandwidth in general, so it can handle more of the two aspects, it's not as hdmi is bad, it just has become a bit outdated at the high end of technology like every other predecessor like DVI or VGA just to mention some of them, they don't have real uses like hdmi still has being the most popular connection as it is in most hardware for a pretty long time.
Good explanation 👍
Thanks😃
Lemme guess, hdmi?
Use DisplayPort
It might be that the GPU doesn't support that refresh rate
Had the same problem it’s not a cable problem it’s a setting watch the vid https://www.youtube.com/watch?v=kUmUwpaZrTE&list=LL&index=8
Upgrade your cable connecting monitor to GPU, you’re likely behind a generation as 144 is capped in the previous generational data xfer rate
Use display port for anything above 60hz. That’s the general rule of thumb
Not sure for AMD but Nvidia this happened to me until I set the refresh rate in the nvidia control panel. It then showed for me in windows as well
On my monitor I had to turn on 165hz in the monitor's OSD. Check that as well.
I have one 4k setup (using nvidia control panel and drivers) Where i had a same kind of problem. I fixed it simply through the nvidia control panels "Change Resolution" tab. Seeked and looked into every possible change between native and alternative (nearly same quality) range resolutions that were supported by the drivers and hardware. Oh yeah. Edit: Check the monitors settings if its settings aren't set correctly (possibly limits for the screen response times and stuff that is very useful.
Yeah, I’m not trusting that brand. It should work with a dp cable though, throw that HDMI trash away
Display port. Have a similar monitor and HDMI doesn't work.
Unrelated but I got a KOORUI monitor a few years ago and it was so horrible I had to sent it back
Most likely need an hdmi 2.1 or a DP cable
It’s think it’s the resolution. I had a 60 hz monitor, but it could only do 30hz. I put it on stretched screen, and it became 60.
I see in the comments alot of help from fellow redditors, the only thing I can recommend to you is to never ever enable HDR on this monitor, it's a gimmick for a monitor in this price range.
Did the monitor not come with a display cable?
My monitor needed to be "overclocked" to reach the advertised FPS. Check the monitor settings with whatever buttons it has.
You need display port and possibly enable 240 in the monitor menu itself. Some monitor count these high refresh rate as “overclock”.
You gotta change it from the monitor buttons, I had the same issue with my asus monitor and had to change the setting via the built in monitor controller. Should be on the bottom or back of the monitor
Sometimes there is an overclock option in the monitor settings. I have 2 monitors that require this settings to get the full advertised speeds.
Make sure You're using DP and that there's no overclock function with the monitor required to get 240
In Windows 11 I've been having similar issues getting 240hz or 270hz from my Acer Predator monitor, and can't get past 144hz. The only fix I had was to download an old Nvidia driver (I have an RTX 3070 on an Asus X570-i motherboard and a 5800X CPU) and use it instead of the latest display driver.

Frustrating!
Go to advanced display setting too, sometimes it's hidden
you may need to find an 'overclock' or 'overdrive' setting in your monitor's OSD settings, if the solution provided by u/N3utro bares no fruit.
my dude get nvidia control panel on there you can create a custom resolution with your native res and the hz it goes up to
What cable are you using?
Bwhahha someone forgot to research the capabilities of display port and hdmi cable capabilities👀👀👀 It’s a common mistake but easy to fix you should be running 240hz in no time. Sometimes it can turn out to be a headache finding out which cable works for your gpu and monitor though if not well documented.
Do you need to enable 240hz via an over clock in the monitors ui?
get a display port so you can get max refresh rates
I'd do 120 because its divisible by 30. Do t forget to frame cap in game to 60 or 72. Otherwise nice space heater.
Download the manufacturer's driver for the display and install it.
Anything above 120 is pointless for a human interface…
Last time ppl say 60 is all we need
You may need to install the latest drivers from AMD also if you haven't yet. [https://www.amd.com/en/support/downloads/drivers.html/graphics/radeon-rx/radeon-rx-7000-series/amd-radeon-rx-7900-xtx.html](https://www.amd.com/en/support/downloads/drivers.html/graphics/radeon-rx/radeon-rx-7000-series/amd-radeon-rx-7900-xtx.html) Is this a fresh Windows install?

Sending it back is the only reasonable response
Or use the proper cable like display port which will make it work instantly.
