Xbox series S screen stutters when I try to play on my 720p roku but it runs fine on my...

Hi Sammyboba! My name is Ricardo an independent advisor ready to help you with this situation!

Probably the situation is because of the refresh rate supported in the Tv or you are noticing the display input lag because it's to high, but to know exactly what's happening you will need to contact the Manufacturer or check the manual to know the specifications and requirements of the device

Your resolution may be the reason it's working. I run my Xbox Series S at 1440p and have capture stuttering like many people in this thread. Maybe the video compression works just fine if you're running your Xbox at 4k.

My connection is 300Mbit down/20Mbit up. I can use the Roku 4's Netflix app fine and get content in 4k, but the XBOX One S is in a different room and used on a different TV. I usually keep my Roku in the bedroom on my old 1080p Samsung.

Wow....................erm....................ok.

1: Im guessing Roku TV is either a specific brand of TV or a set top box or an app.

2: Can this TV/set top box/app run the Series X.

I assume you mean can the Series X run on the TV? if that's the question then yes, the Series X can run on pretty much any TV (apart from old CRT TV's)

3: But missed out the other stuff?

what other stuff?

4: Will it work on HDMI 2.0? yes it will.

Ive got to say though why are you buying a Series X when you have a TV that maxes out at 720p? that's like buying a Porche but then driving it everywhere at 30mph. You would be better saving your money and buying a Series S, all of the benefits of having
a Series X are completely redundant if your are using it on a TV that can only display at 720p.

Actually my TV was in 720p mode and for some strange reason it doesn't have strong 3D and 720p mode but the 1080p mode is designed for 3D therefore the 3D looks better. As soon as I switched it to 1080p mode on the Xbox One S the 3D became more obvious.

The only reason I have it set to 720p mode before was because my VGA CRT can run 720p but not 1080p, at least not run it's without chopping off part of the screen.
