After latest update , my series X no longer does 4k

Hi QuiDonGinn, my name is Rodrigo. I'm an Independent Advisor and a member of the Microsoft community and I'd love to assist you today.

I am sorry to hear that.

Please, reset your console, so we can rule out settings issue.

Before you continue, make sure you've got the account sign-in information. You'll need it to log back into your console after the reset.

You can follow these steps:

Press the Xbox button to open the guide.

Select Profile & system > Settings > System > Console info.

Select Reset console.

Select Reset and keep my games & apps.

Let me know if it works!

I had the same / similar issue with my old 4K 60hz none HDR / HDMI 2.0 monitor when watching movies and some times in games with the Series X,

As soon as i upgraded my monitor to a 4K 144hz monitor that has HDR / HDMI 2.1 ports, i no longer had this problem,

I'm not sure what the problem is, but my guess is that the HDMI 2.1 port on Series X doesn't play well with HDMI 2.0 port of monitors, or it's the Series X trying to force HDR on, even if the monitor does not have / support HDR and the HDR in Series X menu's is turned off.

Yes, I currently own an X Box One X

When does the new X Box series X release this year?

Will it have blue-ray?

I have a 65 inch, 4K television.

Will I see a difference in graphics with the new X Box on my 4K?

Xbox Series X will release Holiday 2020, given Xbox's track record of releasing new consoles, they've usually been around November.

It will have Blu-Ray.

With the Xbox One X, it uses checkerboarding to get 4K resolution, though it's not true 4K, it's what allows the One X to get to 4K,

With the Xbox Series X, it will use true native 4K, you may see that the Series X will look a little better at 4K than the One X at 4K.

Yes but as mentioned you will have issues

It upscales not native

Only the xbox one x and series x are 4k native

True 4k vs 1440p

Most.games will.only run 1080p max on series s

It will do less CPU intensive stuff like 4k streaming

Series x does 4k 60hx with possible 120hz (dropped fps )

Xbox one x does only 4k 30hz

Nothing does 8k except for tech demos because disks can't hold 8k and player does 8k you have e.to wait for a future update

And series s isn't capable of 8k it only upscale to 4k only series x and maybe the refreshed ps5 coming out soon could possibly do 8k

Series x we have to wait and see when the update happen
