I have linked my Windows 10 laptop to the TV by using an HDMI cable. The laptop has a resolution of 3840×2160 and a refresh rate of 60Hz.

The TV’s resolution has been set to 3840×2160 automatically, but the refresh rate is displaying as 30Hz.

The option to increase the refresh rate is not available, which is why I am unable to make any changes to it.

I am able to modify the refresh rate to 60Hz after adjusting the TV’s resolution to 1920×1080.

I’m wondering why it’s not possible to set the TV’s resolution to 3840×2160 and the refresh rate to 60Hz. I’m unsure if the problem lies with the HDMI cable or Windows.

Although my TV can support a maximum refresh rate of 120Hz, I am unable to locate that option.
