I've connected my laptop(Windows 10) with the TV using an HDMI cable. The resolution of the laptop is 3840x2160 and the refresh rate 60Hz.
Now, when I change the resolution of the TV to 1920x1080, I'm able to change the refresh rate to 60Hz.
Why can't I put the resolution as 3840x2160 and the refresh rate at 60Hz for the TV? Does the issue have to do with the HDMI cable, or Windows?
My TV's max refresh rate is 120Hz. Supposedly I should get that option also, but it's not showing there.
