Does the Series X console automatically upscale 1080p movie discs to 4k?

Your television is already upscaling it to 4K, it doesn't matter if the Xbox does it. Everything is displayed in 4K at the native resolution of the panel

Just keep in mind that upscaling is not real resolution

Your television is already upscaling it to 4K, it doesn't matter if the Xbox does it. Everything is displayed in 4K at the native resolution of the panel

Just keep in mind that upscaling is not real resolution, the TV is reporting the input signal, not what it does with it.

No, it doesn't do that. The movie will show in 1080p. Only 4K movies will show in 4K.

What resolution are you trying to run at

If 4k 120 Hz then no it won't run at thaf

The max for series s is 1440p at 120hz

It will play at 4k bur only some games and with issues

The series s is meant for 1080p 120 max

With suggested 90hz

The xbox series x and ps5 and switch pro are the only 4k consoles

One x does 4k at 30hz and ps4 pro upscales

Xbox One S is not really a 4K console,

4K Media Content - Yes

You can play 4K Blu-ray DVD's or Streaming services like Netflix in 4K just fine if your paying the the 4K subscription options,

4K Gaming Content - No

As for games, it only plays games at 1080p but it is upscaled to 4K, other wise a 1080p image without upscaling to 4K, will look much worst on a 4K screen than what it would do, if it was only displayed on a 1080p screen,

A 1080p image upscaled on a 4K screen does look a little better than a 1080p image on a 1080p screen, but it still a 1080p image made to fit a 4K resolution screen, which is what the Xbox One S does

Xbox One X is a 4K console,

4K Media - Yes

4K Gaming - Yes

The issues is not the TV, it's the Xbox One S not being an Xbox One X.
