My TV used to support HDR, but now it doesn't.

my tv doesn't support hdr.

Hi,

Not all TV's support HDR on all HDMI connections.

On my Sony Bravia 4K TV, only two out of the four support HDR even though they all support 4K resolution.

This could very well be the issue,

I have a Samsung 4K HDR TV, with 4 HDMI 2.0 ports, but only one of my port's supports HDR, ( HDMI 1 ),

If i want to use to my PS4pro with HDR, i have it in HDMI 1, but then if i want to use my Xbox One X with HDR, i have to swap my HDMI cable's around, so that my Xbox One X is now in HDMI 1,

Best check the TV's manual to find out which HDMI port uses HDR,

Or try connect the Xbox One X into the HDMI port where you're PS4pro is, and see if HDR then works.

Samsung 28 inch 4K UHD monitor is the one I've used before. It doesn't support HDR, btw. Get a monitor with HDR atleast 2.0. Superior response than TV? I guess TVs are also decent.

Hey l am BATMAN,

That TV doesn't seem to have any HDR capabilities. Looking at the
LG 55UB8500's Spec Sheet, there's no mention of HDR or UHD Deep Color, where as their other TV's that do support HDR have it included in their spec sheets.

The next best step I recommend taking is reaching out to LG support to double verify if the exact TV model you have supports HDR or not. So far with the info we were able to find, it doesn't seem like it does unfortunately.

Keep us looped in!

As far as I can tell it does not specifically state that HDR10 is required just to set the 4k resolution (just that it is required for HDR), that wouldn't even make sense. HDR10 is not required for something to display content in a specific resolution, the
resolution 3840x2160 doesn't require HDR to work, resolution is independent of HDR.

And I already know that my TV doesn't support HDR or at least doesn't support the HDR10 protocol, but that is fine, I don't care about HDR, but I do care about running things in the 3840x2160 resolution at 60Hz (which my TV definitely supports). If this
is the case MS has made a device that only works with like 10 models of TV's... why are they even selling this?

Seems to me like either a bug or an arbitrary restriction put in place to make people go spend $1500-$5000 on a brand new 2016 OLED TV supporting HDR10. I see no legitimate technical reason that the resolution can't be set to 4k without HDR. Even 4k blu-rays
with HDR do not require the TV to have HDR, it just shows the film minus the HDR details when played on a non-HDR TV.

This is what I like to call total hog wash and MS needs to fix it.
