6 troubleshooting tricks when monitor capped at 120Hz

There you can choose from a variety of refresh rates that your monitor supports. If you plug the HDMI 2.0 cable into the correct ports and your monitor or dual monitor supports 240 Hz, with a perfect CPU(single-core or multi-core CPU) and motherboard, you should be able to see 240 Hz.
2. You are using an incompatible display port or HDMI
Unless you’re a tech geek, it’s normal to buy a cable and hope for the best. In terms of technology, the video cables or audio cables used are very important. Using the wrong cable could mean a 240 Hz monitor will only display 120 Hz as the cable limits the monitor’s ability to operate above 120 Hz.
The standard HDMI cable doesn’t support 240 Hz, so it’s easy to see why your screen is only showing 120 Hz.
To change this you need at least a 240Hz compatible cable, e.g. HDMI 2.0.B
If you bought your monitor brand new, this cable should normally come with your monitor in the original packaging.
3. Outdated Graphics drivers
However, this is very unlikely and an outdated GPU driver could affect your monitor’s Hertz values for some reason. This is likely only true if you haven’t used your computer and graphics card in a long time or haven’t had an update problem in years.
Make sure all of your GPU drivers are up to date with the appropriate GPU software for great video quality.

5. Check if your console supports 240 Hz
If your monitor is 240Hz but only shows 120Hz, another common problem is that while your monitor supports 240Hz, it might not be your console.
For example, all PS4 models (including the PS4 Pro) only have a maximum refresh rate of 60 Hz. This also applies to the Xbox One and all of its models.
PS5 and Xbox Series X can run at 120 Hz with 1080p resolution.
Most likely your console doesn’t support 240Hz unless you’re playing on a PC.

6. Plug the cable into the wrong ports
Finally, perhaps the craziest thing you can do is plug the appropriate cables into different ports. The only reason I know it’s possible is because I did it myself, despite the shameful claim.
And no, I haven’t connected HDMI 2.0b to a normal HDMI connector port yet, because that’s not possible.
I did this by plugging HDMI 2.0B into the HDMI 2.0 port on the computer case to make sure I never plugged it into the GPU port, but somewhere else. Yes, it’s crazy, but it’s happening. Make sure it’s not something you’ve done.
To prevent your 240Hz monitor from running at 120 Hz, you must connect HDMI 2.0b to the GPU port. The other end of the cable should go to the HDMI port 2.0b on your new monitor. Simple, isn’t it?
