weird youtube resolution issue on series s. all content thats not uploaded in 4K just...

the series s support up to 1440p but to use that resolution you would need a monitor not a tv as most if not all tv's support 1080p or 4k.

series s will upscale to 4k though.

I recently upgraded from the S to the X, and I personally feel that speed and graphics are better. As others have mentioned the X plays 4K content and displays in native 4K resolution. Where as, the S can display up to 1440p resolution for games and 4k resolution
for Movie/Video Content (IE 4K UHD Blu-ray disc, content on the Netflix app, etc).

TLDR:

If you wanna play games and watch movies/shows in 4K you'll want the X.

Otherwise I would say the S if you just wanna watch 4K movies or shows.

Your information is not correct. Actually when you set the xbox one S console resolution to 4K UHD, everything on the console—Home, games, and apps—will display at 4K. 4K content is displayed in its native 4K resolution, and other content (like 1080p content)
is upscaled to 4K.

Hey there!

Have you gone through the steps and suggestions on our
Troubleshoot 4K on Xbox One S support page? One of the steps mentioned is setting the TV Resolution on your Xbox One S to 1080p, while ensuring the 'Allow 4K' box is checked within 'Advanced TV' settings. The TV resolution setting is specifically for setting
how non 4K content is scaled, and will still allow native 4K content to play at 4K on your display.

If the flicker issues persist with native 4K content after setting your TV resolution setting to 1080p, please post back the brand and model number of your 4K display so we can take a deeper look!

I use a capture card because of this and another problem I encountered is that if you capture 4k HDR videos on external when you upload them to Youtube only the 4k aspect of it uploads but not the HDR and the video ends up looking weird
