UHD HDR Blue Ray Disc won't play

I have got a problem playing a blue ray disc, that is also HDR (It is a Christmas gift and luckily there is also a "normal" Full HD Blue Ray disc in the box which I can play with no problem). The disc claims, that for the full HDR experience I need HDR compatible UHD TV, Ultra HD Blue Ray player, and High Speed(2.0) HDMI cable.
I knew, that my UHD TV has only HDR+ technology and is not HDR compatible, but I thought I could still watch the movie, just not see the best picture. Instead, the TV claims it lost the signal of the Blue Ray Player, and tells me to turn it on, and turns dark, whenever I try to play the disc. Is it utterly impossible to play the disc, or is there a workaround? Could it just be that my HDMI cable is not 2.0? (I am not sure) If I make sure it is 2.0 cable I still could play the disc, or I would in all case need a new TV for that?

Do you have a Ultra HD Blue Ray player? Such a disk doesn't play on a normal Blue Ray player.

In reply to: Re: player

Yes, and the UHD Blue Ray player and the UHD TV are the same brand (Samsung) too.

Otherwise, it’s a series of rough guestimates Happy

Model numbers

In reply to: All makes/models/titles needed

Well, here you go:

The UHD Blue Ray Player is a: Samsung UBD K8500 (

The UHD TV is a: Samsung UE55MU6449 (

So the thing is the TV is not HDR compatible, but I thought it should still play the 4k content just without HDR. Turns out it cannot, as the tv loses the signal as soon as I push play for the disc, unless the problem is that I do not have a 2.0 HDMI cable.
What do you think?

That model *does* support HDR

In reply to: Model numbers

You are confused.

Try another HDR source and/or titke and see if that works before we assume anything besides a problem with a specific title/settings. Also try to access HDR content via youtube on the Samsung.

Which one now?

In reply to: That model *does* support HDR

NOW I am confused because you are not specific enough XD
"THat model does support HDR"? Which, the TV or the Blue Ray Player? Because I know the player does, and the TV does not have it....

Youtube on the Samsung... both the TV and the player are Samsung, which one do you mean? Grin

Still confused...

In reply to: Re-read the first claim you made (n/t)

Well I am still confused but it does not really matter.
Youtube automatically downscales anything I try to play. I can play a 4k video on my HD laptop because it just gets downscaled. "YouTube will automatically detect which type of display you are watching this on and down convert this video to SDR"

I can play a 4k HDR video on my Pavilion HD laptop, in 4k resolution, it is just very laggy, and does not have HDR:

The TV only have HDR+, which is not actual HDR. The Blue Ray can play HDR, but that does not help. The TV cannot view it. Unless the problem is that I need a 2.0 cable...

It starts up even, the disc, as in there is a screen with a logo of the movie filling up with color, acting like a loading screen(which is same on the Full HD blue ray disc counterpart), but after that "Check device activation", as in the TV loses the signal, the connection with the blue ray player immediately once it tries to play HDR content.

HDMI UHD color...

In reply to: You must have a different model HDTV

I have always belived it could not support HDR because it does not have any option for that in the menus. Only HDR+. Now I am not sure.

As I posted below there is a "HDMI UHD color" option, and if I turn that on for any device it loses the signal for that device sooo, that is pretty suspiciously the cable's fault, or is not it?

I thought we chatted about cables.

In reply to: HDMI UHD color...

We know there are cases where it is the cable. The famous PS3 Slim debacle. Some LG TVs and skipping or dropping audio over ARC and so on but not a single tech would put their reputation on the line and tell us it's the cable.

This is a 7 dollar item that good techs carry with them to swap and see. If you want to test and know it's a cable I will share that years ago we had network analyzers that ran over 40K USD (in the military they buy them, IRL we rent them) that we could check out cable quality.

So back to Earth and we just open up a new 7 dollar cable and try it.

Make sure you have enabled HDR in the HDTV settings

In reply to: Still confused...

Also, make certain the HDMI port supports HDR.

(Hint: read both user manuals!)

In reply to: Yes

Once I had a DVD that glitched (first time I had that issue long ago) and I google the title and it turned out everyone was complaining. Sometimes they goof the title.

Here the HDMI 2.x cable is under 10USD.

In reply to: Nod to Pepe7

If you suspect that, what stopped you? NO ONE I know will tell you that it will fix this. No one.

You claim the TV doesn't have HDR so wouldn't that be the end?

In reply to: Here the HDMI 2.x cable is under 10USD.

This is the same arguement as "why don't you just google it"... This forum is to ask questions like this, is not it?
I cannot know if someone cannot tell me if I just need to switch cable type or it does not matter. That is why I ask, maybe there is someone who can help.

Collapse -

In reply to: Well--

If you expect folk to tell you another HDMI cable will fix it, I have bridges for sale. It's a good thing to get corrected since once in a while it can help but to say "this will fix it" is setting that person up to fail most of the time. So those that know will say try it and won't commit.

Not the same as a "google it."

In reply to: Nope.

I have not enough knowledge so I did not know what to expect, so I asked, to make sure.

High speed?

In reply to: The HDMI cables I use is this one most of the time.

Wait, the cable I currently have is also "High Speed". Does that basically mean 2.0, or that is separate?

Collapse -
Just try another cable

In reply to: High speed?

Labels mean very little.

In reply to: High speed?

But in the world of cables there is marketing that has made a mockery of standards. All HDMI cables are high speed to me.

As Pepe7 wrote, be sure you use ports that note HDR. Some devices and TVs don't do all tricks on all ports.

Cable, maybe, probably?

In reply to: Sorry

There are two ports on the Blue Ray player, one I currently use, and the other is "audio only"... And from all the 3 ports on the TV none mentions HDR ^^"

However I am now uncertain. Altough the TV only has HDR+ option in the menus, when I play content on Youtube that claims to be HDR, the "Picture type" (like Normal/Vivid/Movie ect) has a little HDR label next to it in the menus....

Also I tried to switch ports, and put the Blue Ray player in another one, but the same thing happens.

But also, there is an option in the TV-s menus that says "HDMI UDH colors". If I turn that on, it loses signal immediately. I think that means the cable is the problem, because it is not the correct cable so cannot carry the HDR signal, right?

Something is lost here

In reply to: Cable, maybe, probably?

You seem to make a lot of assumptions without referencing what is written in the user manuals. Start there and backtrack...

Collapse -
Manual is not so useful

In reply to: Something is lost here

THe paper manual is nothing and the online manual does not help much either. I'll just try that cable and if it still does not play it is the disc itself...

HDMI cable 2.0 E-bay

How could we possibly know for certain?

In reply to: HDMI cable 2.0 E-bay

Understand, ebay is ebay. Same risk for everyone.

Will try

In reply to: How could we possibly know for certain?

Well I bought it and will try it...whatever..if that does not work it must be the disc itself than.

Now I am a noob there a way for me to close the topic?

What country are you in?

In reply to: Will try

I think looking more closely at the disc/region/player settings might be helpful.

If you could post links to both user manuals, I will take a peek just to rule out other issues. No need to close a topic yet. Everyone can learn from the process here Happy
