xbox one x not displaying picture to my tv after preview build

The Sky Q box will only be able to see what it is plugged into, in your case its plugged into the Xbox One X.

Why don't you plug the Sky Q box into the TV, let the box "discover" your LG TV, once the Sky box knows what sort of picture it can display then plug the Sky output into the Xbox One X input.

It would depend on your TV how that is able to display the image of two different sources.

There had been experiments with 3D capable TVs and their shutter glasses, where the TV "flickers" the signal from two different inputs in sync with the 3D glasses, so one person sees their screen and the other person sees their own screen.

However, in that case you'd know that your TV can do that, and you wouldn't ask here 😉

Or if your TV can do Picture in Picture, a person can play with a large picture, while the other person has to live with a small preview picture in the corner. But that's hardly convenient.

However, the Xbox One is able to stream to a Windows 10 PC or laptop with the Xbox App. That way one person can play on the TV, while the other person gets the video feed of the console on their PC, and remote-controls the console through their controller
connected to the PC.

But to display the video from two different consoles on one screen is a function your TV needs to have. Not the console.

Had this problem contacted vizio and I had to uncheck the allow variable refresh rate in tv&display options on the Xbox one x and also had to turn off variable refresh rate in the pro gaming engine in the advanced picture settings.

Hi,

If you're wondering if the picture will look better, as in sharper, then the answer to that would be a definite no. Will it look worse? Well, that really depends on the TV rather than the Xbox and how
well your TV scales 1080P resolution on the 4K display.

Regardless of 4K display, if you hook up a 1080P console to it, it will display in 1080P, indeed, the TV will drop to this resolution. I have the One X, so my enhanced games will play natively in 4K and
look great automatically. I do also use a Nintendo Switch on my 4K TV and it scales really well at lower resolutions.

As long as you buy a decent branded model, it should scale fine.
