LG CX 4K 120hz OLED65CXPUA Issue resolved

To achive 4K at 120hz your TV needs to have HDMI 2.1 ports and supports 120hz, such as the LG CX TV,

The bandwidth limit of HDMI 2.0 will only allow 4K at 60hz.

Right now I’m on a 42 inch Samsung QLED 4K HDR set, but before the Series X is out I’m planning on upgrading to the LG C9 or CX in 65 inch. I need that HDMI 2.1 120hz OLED goodness in my life.

My panel has no issues, have tested with everything

CX is new model 2020 has 4k 120hz dolby vision full support

but if the video feed is not going though a HDMI 2.1 port, the signal / bandwidth to the TV is limited by the HDMI port the it uses, be it a straight connection or some sort a splitter,

4K 120hz requires a HDMI 2.1 port, no HDMI 2.1 ports, no 120hz at 4K

The LG CX has 4xHDMI 2.1 ports! The Xbox will be directly connected to it as I describe above.

eARC is not a signal splitter device. It is a feature of TVs the past few years that returns audio to an external device like a soundbar or amplifier.

hi i would like to have 120 fps on my tv with my serie x , i take yu a screenshot of settings tv, i dont understand why in settings xbox they dont proposed 120 fps at 4k but i can play 120 fps at 1080p ?

You won't get 120 fps on that TV, as it's only a 60hz display, 60hz = 60 fps at most

To get up to 120 fps at 4K, you need a TV that supports 120hz and has HDMI 2.1 ports and again your TV only has HDMI 2.0 ports, but most games on the Series X are locked to 60 fps at 4K,

Something like the LG CX is the best TV to get at the moment, and that's a TV that can go 4K at 120hz,

A 60hz display = up to a maximum of 60 fps

A 120hz display = up to a maximum of 120 fps.
