HDR making my screen dim when playing

Hello,

My xbox one x has an issue with loading games in HDR. When a game or netflix starts up. My screen dims dark. Like it fade away. All colours are dark and not bright.

I have a 4K/HDR tv with a 10 bit panel. And it doenst work.

I tried everything. Switching settings from my tv and xbox, hard reset, different HDMI 2.0 port and cabel. Only HDR in 8 bit mode doenst go dark. But I know my TV has an working 10 bit panel that works with other content beside my xbox one x.

Same here. It looks as if you have screen dim on as a power saving feature. The problem with this bug is that dims the screen as soon as you start and play an hdr game or app.

I am having a similar issue on my Xbox One S connected directly to my Samsung JS8500 tv. When I open the netflix app the screen becomes very dim and the screen doesn't return to normal until the app is quit. HDR content looks great using the Netflix app
on my TV by the way, not dim at all.

You will see a slight change in colors on your monitor when you turn on HDR. To activate on the console a TV with 4k is required.

I'm not sure why and if that's the main reason or one of the reasons but a 4k TV screen has more nits than a monitor screen and when you turn on HDR the screen dims a bit

So the higher the NITS of the screen, the higher the illumination.

… it does say this one that link you gave - When using the NU8000 for HDR PC Gaming, there is currently an issue with the 'Standard' picture mode where the screen became very dim and we were unable to change it. So maybe
there are issues with this TV and dimness.

Hi,

What happens if you turn off both allow 4K and the HDR setting? (turning off Allow 4K should turn of HDR anyway).

When your playing games in HDR and go back to the dashboard there will be a momentary pause or black screen. This is normal as the Xbox dashboard operates in SDR and both the monitor and the Xbox should switch back to SDR.

I'm just curios to see if there is an issue with switching between HDR and SDR on this monitor.

Also, if I'm not mistaken, the M27Q is an older HDMI 2.0 display and that can be bandwidth limited. Besides, this is only an HDR 400 display which means it doesn't get bright enough for HDR to really stand out. Decent HDR needs HDR 600 or more to actually make much of a difference together with good local dimming.

Just because it can do HDR doesn't mean you need to have it on. On displays with poor HDR implementation having it on can actually make the picture worse.

Have you updated the monitors firmware?
