You’ve enabled “input signal plus” and change the HDMI input label to PC ?

After that all you should have to do is select 1440p from the GPU driver control panel resolution section.

Hi, yes i’ve done all of this, but it only shows 60Hz to 75Hz, tried to disable freesync and still, no 120Hz available

I’m able to get 120Hz at 1080p when disabling input signal plus tho

What does moninfo say in its report https://www.entechtaiwan.com/util/moninfo.shtm

It should list all HDTV resolutions supported by the TV, if it cannot see them then something is very wrong.

Hi and thanks for your time, it says “Detailed timing #1……. 2560x1440p at 120Hz (16:9)” under the IA/CEA/CTA-861 Information list.

Theres nothing more than 1080p in hdtv resolution, but 2k and 4k works

Well the resolution and refresh rate are there but for some reason the GPU driver isn’t presenting them as options.

My best guess is Windows + Radeon driver are the problem, unfortunately GPU drivers are difficult to fully remove.

If you have a HDD/SDD spare try a clean install of Windows on that and see if it gets the correct resolutions detected in the Radeon control panel. That could at least quickly confirm the existing Windows install is the source of the problem in some capacity.

Alternatively you could also attempt to uninstall all AMD Radeon software then after that run the AMD cleanup utility. https://www.amd.com/en/support/kb/faq/gpu-601

After the reboot attempt a fresh install of the Radeon driver.

Make sure you have backups and PC isn’t storing anything important.

It works! After desinstalling and installing again the GPU driver, i could finally see 1440p 120Hz showing in the advanced display setting, in the available listed resolution. Thank you very much for your help, really thought the tv had a problem
