Xbox one s causing screen flickering with lg tv and monitor at 4 k 60hz only.

what is your Problem?

Flickering Screen on Xbox

Flickering Screen on Xbox with HDR

Screen goes Black on HDR with Xbox ?

You talk about going black but have flickering on Topic.

There was an official Problem with HDR Flickering on that TVs and Xbox but that should be fixed a time ago

The screen flickers when HDR or HDMI ULTRA HD Deep Colour is on in the TV, after a while of flickering it goes black, then the TV loses the signal from the Xbox. That's
my problem.

If I deactivate HDMI ULTRA HD Deep Colour, then there's no more flickering and no more black screen.

Well it isn't fixed yet, I'm 100% sure I am on the latest firmware on both the LG C9 and the Xbox One X.

I've been looking at the LG

27" LG 27UK650-W 4K UHD HDR Monitor, IPS, 3840x2160, 60Hz, 5ms, FreeSync, 1000:1, 450cd/m², HDMI/DP

only looking at max 28 inch screen size due to working area where the monitor is going to go

My xbox one makes my tv flicker black non-stop when i open games and apps. I switched HDMI cords to see if it was the issue and it still flickers. It's not the tv either cause i've tried a separate xbox one and no issues. I need to know the issue here with
the xbox that keeps making the screen flicker black. I did the hard reset with holding the power button down and it didnt fix it.

Your Dell monitor's
manual suggests that it is only using HDMI 1.4, which is only sufficient for 4K@30Hz. It seems 4K@60Hz is only feasible when connected with DisplayPort, which is not supported by the Xbox.

Xbox One S requires that the 4K display has at least HDMI 2.0, which has the necessary bandwidth to display 4K@60Hz.

4K TV sets are pretty much expected to carry this HDMI specification, but 4K computer monitors are more of a mixed bag.

Hey Miss Bijoux,

If I turn off "Allow HDR" then the content plays as normal. The washout only happens during HDR video playback and nowhere else.

I contacted LG support on this after some investigation on my own. I noted that by checking my signal on the receiver HDR video playback on the Xbox One S is 10-bit RGB at 24Hz.

All other devices I've used seem to use either 12-bit YCbCr 4:2:2 60Hz (PS4) or 10-bit 4:2:0 60 Hz (HDR Blu Ray Player) for their HDR content. LG Says they don't support 10-bit RGB.

Now here's where it gets interesting. HDR Games on the Xbox One S come through at 10-bit YCbCr 4:2:0 60Hz. So I tried disabling the 24Hz signal in the Xbox One S.

Now it puts out a 10-bit YCbCr 4:2:0 60Hz signal when attempting to watch HDR video... but the dimming issue still persists.
