Amazon Prime 4K HDR Series X Problem

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.

Have you looked through the Xbox Support channel on : "Do my TV and Xbox support 4K and HDR?"

If same problem persists, try other HDR apps like Amazon Prime, Netflix to test the HDR settings on videos. If you are still getting the same results for Xbox and the apps, I would lean heavily on your monitor not being capable as intended.

Since my TV does not support HDR, I cannot activate it and it is disabled by default.

As I really like Interstellar, it was offered to me in 4k without knowing that I do not have a 4k TV.

What I mean is Xbox series X has a very dark image with HDR blu-ray. But when I watch HDR blu-ray on my PS5 I have no problem.

I think Xbox series x is not converting HDR to SDR correctly but that the ps5 yes.

On the other hand, blu-ray 4k comes out very well on a 1080p TV.

I've bought a few HDR/4K discs.

I mostly watch HDR/4K content through Amazon and Netflix though

Amazon had Scorpio’s this morning, you have to click the Xbox one X and then change the “size”. So they are still out there. My 1-X will not display 4k on my Visio TV even though it detects the TV having 4k with HDR 10.
