HDR output to Decklink Mini Monitor 4K

hello All,
I cannot get the Decklink card to play HDR material...
Don't know if i have a setting incorrect, or something else...
Has anybody else had any luck with getting the Mini Monitor 4K card to play HDR?
It plays regular video just fine.

below are my settings,
and my preferences settings
and the settings recommended in the resolve manual

Any suggestions are Welcome!!

Thanks!!!

What are you color management settings. Are you outputting HDR?

yes, it outputs HDR10+ no problem . Looks very nice on the TV when played from a USB drive.

Post a screenshot of your Color Management page of Resolve.

Do you mean it won't output 4K? Or do you literally mean only HDR has a problem? Like some HDR metadata is not getting through to the monitor?

it outputs UHD to the HDMI TV no problem
it looks fine, for regular footage -- nice color balance, etc

it just does NOT make the image HDR while i am outputting through the Decklink card... while monitoring / color correcting it
i am back to just trying out settings,
rendering,
playing on the TV via a flash drive plugged into the USB port on the TV,
then going back to Resolve and wiggling some dials,
rendering... etc

i "guess" it is not getting the HDR metadata... but i am no expert ...

Also
when i open up the rendered files ( h265 HDR MP4)
in Blackmagic Media Express,
it connects to the Decklink card and plays UHD video just fine...

it just does NOT trigger the HDR on the TV

the same rendered file
played from the USB port on the TV
triggers the HDR on the TV ,
the little marker that says "HDR" appears in the corner of the TV,
and it looks like HDR.

so the Blackmagic Media Express and Resolve Studio are doing the exact same thing.
HDR is not being triggered.
so i guess its NOT a setting in Resolve, since Media Express has NO settings to change...

Any ideas?
thanks!!!

From the Reference Manual.

Monitoring an ST.2084 image is as simple as obtaining a ST.2084-compatible HDR display and connecting it to the output of your DeckLink 8K, DeckLink 4K Extreme 12G, or UltraStudio 4K Extreme.

Decklink Mini Monitor 4K supports HDR. I have one at home and it activates HDR with Resolve on my Samsung QLED.

Well...I didn't wrote the manual.

What kind of TV do you have? You may need to activate HDR manually.

Well...I didn't wrote the manual.

It was a later addition. I forgot which driver version they added it.
The manual may not reflect that change.

I don't see a way based on the manual.
Try enabling Dolby Vision in the Color Management page of Resolve. See if that triggers Dolby and activate HDR.

okay, i turned on the dolby vision checkbox in the color management page
and restarted Resolve ...
still no bueno...
Still just outputting normal image through the decklink card...
you think its my TV? Time to upgrade to a OLED?

I dont think it is a hardware issue (OLED vs LED). It is likely a software issue. Either Resolve is not transmitting the proper HDR metadata or your TV is not respecting the HDR metadata.

I assume all of the HDMI ports are HDMI 2.0 or better?

yes , the TV specs say HDMI 2.0 ports,
the cable says HDMI 2.1,
and i assume the decklink card is transmitting at HDMI 2.0 spec.

Is there any easy way to check to see if Resolve/ Decklink-card are transmitting the HDR signal?

i have a Ubuntu install on this same hardware, and i tried to get Resolve to work on Ubuntu, so i could test the hardware-- Decklink-card--- TV, but since i have a AMD RX580 GPU, i have not been able to get Resolve on Ubuntu working... Sigh...

What specific monitor? How is it connected to the Decklink?

A stupid question but - how does the picture look on the TV, does it look good or washed out, greenish, colorless, dull? Perhaps you're getting HDR but not the right brightness?

the image looks very nice-- color is great, well balanced, better than the computer monitor etc...
its just overly bright and not HDR.. no dark blacks, etc --
its just like a render of the file without the HDR metadata turned on .
also, the TV triggers a little "HDR" logo for 3 sec when each HDR clip starts playing ... and the Decklink card does not trigger the HDR logo at all..
so i am pretty sure that no HDR metadata is going through to trigger the TV

55R625 TCL TV
the decklink card and the TV are connected via a HDMI 2.1 cable i just bought...
at least it is printed on the box HDMI 2.1
so i cannot iron-clad guarantee it isn't a Chinesium ripoff...
but seems legit...

The cable naming doesn't matter (and there are no 2.1 cables per se, only ultra high speed premium), HDR metadata goes through any cable. If you're on Windows, can you try connecting your regular GPU to the TV, activate HDR in windows and see if that works, i.e. whether HDR label pop up and whether you get HDR picture settings unlocked.

i have MacOS 13 ventura going right now for the Resolve machine
and a Ubuntu bootable install also on the same hardware, but have had NO luck getting resolve to run on that install
so no windows currently on this machine...
maybe i will try a windows install and test your concept
Thanks man!

Good morning
I have the PC workstation in the same room where I have my old LG 65B6V OLED and I would like to use it as a large HDR monitor to check the preview.
For this I have been thinking of purchasing the DeckLink Mini Monitor 4K PCI card.
Before purchasing it I wanted to confirm, after setting the HDR rating on "Color Management> Color Space and Transformation", does the OLED display automatically switch to HDR?
Thank you very much for the confirmation.

Do you mean it won't output 4K? Or do you literally mean only HDR has a problem? Like some HDR metadata is not getting through to the monitor?

I'm dealing with this problem, Decklink MiniMonitor 4K won't output UHD to my monitor, an EIZO CG2700X.
BMD european support is resisting to admit that the card is faulty, well into the warranty period...

Also, to really work in UHD/HDR, some settings from the initial photos of this thread should be reviewed:

my_video_moitoring_settings.png (108.25 KiB) Viewed 4021 times

"Use 4:4:4 SDI" should be checked, as it affects the HDMI output as well;
SDI configuration should be "Single link" for the Decklink MiniMonitor 4K
Video bit depth should be "12 bit"

And sticking to the manual:
"Monitoring an ST.2084 image is as simple as obtaining a ST.2084-compatible HDR display..." especially one that really shows the kind of signal that's coming in.

You need HDMI 2.1 in order to output anything higher than 8-bit. There is not enough bandwidth with HDMI 2.0 to do 10 bit or higher in 4K.

My mistake. I didn't realize you are working at 30fps.

Per BM Spec

"8, 10, 12-bit RGB 4:4:4 in all modes up to 1080p60, and 8, 10-bit YUV 4:2:2 in all modes."

Hello,
i just tried your settings in Resolve... with my TCL TV...
and i still get no HDR from the Decklink card...

here are my settings now -->

i think my TV is at fault ...
but maybe its the decklink card... if your card is also acting up and not outputting HDR...


thanks!!

Try switching to 1080p and 10bit.

12 bit or 10 bit did not make any difference ... same result...
1080P 30 got me this-->

Good morning.
I am intent on purchasing the card, but I have a doubt that it cannot transfer 4K HDR files @59.94fps or 60fps coming from camcorder.
As from the specifications it should transmit signals :
Ultra HD video standard
2160p23.98, 2160p24, 2160p25, 2160p29.97, 2160p30

If so, it is not useful for me with shooting @60fps, can you confirm this?
Thank you

Unless your TCL TV really does have SDI connection I would suggest your turn off 'Use 4:4:4 SDI' in the Video Monitoring settings you show here. Not sure if its your cause, it makes no difference here when I tried turning it on, but then I'm using a 4K Extreme 12G Decklink which is HDMI connected to an Eizo.

That's correct. I needed to switch from the Mini Monitor $K to the 4K Extreme 12G for my UHD HDR 50p work. Never looked back though

So the model that allows 60 fps, after DeckLink 4K Mini monitor is Decklink 4K Extreme 12G or are there lower cost models?
Thanks

Not that I know of unfortunately.

Wouldn't it be possible an alternative solution such as to set the timeline for example at 30fps display all color grading corrections on the monitor and then only before export reset the timeline to the clip value (60fps).
Why might this not be possible?
Thank you

Just thought to share a fix here (for MiniMonitor 4K) that I have to do every so often: unseat and reseat the card within the computer. Shut down first and do it with A/C power turned off (usually the power supply has a switch). Then disconnect input cables to monitor and do a hard shutdown to that as well (if it has a switch, or just leave it unplugged for a few seconds before turning it back on).

Might not be a fix for every problem, but for me at least, whenever the card is stuck outputting only 1080p or is not triggering HDR, this is what I do and it fixes it.

To prevent the card from acting up, and the monitor, I now have stopped switching off A/C power in my computer after every shutdown, and I also don't turn off the monitor, but let it go into power saving mode automatically once it detects no signal.

Now I understand why I've seen some colorists mention they don't turn off their monitors even when not outputting anything because it "acts up."

Thanks for the advice, it is helpful to know this procedure.

You can keep your timeline @ 60 fps and set Minimonitor output to 4K 30 fps.

Thank you Infinite.
Can you also act via Timeline setting or is it more correct via Video Monitoring?

It's up to you, I like to set it up per timeline since I can have multiple timelines in a project with different settings/resolutions.

This is an older topic that doesn't appear to have provided the answer to the op's question. Although the op's tv is HDR compliant, it's HDMI2.0 input is not, a rather unfortunate oversight. In other words, it's potentially HDR compliant through the built in smart tv apps and USB port, but for HDR signaling with HDMI it must be version 2.0a or later. The devil is in the details, the little "a" following the 2.0 version number is required. Google or Wikipedia HDMI 2.0a for more information. This tv in addition to not being HDR compliant with the Decklink Mini Monitor 4k would also not be compliant with HDR from any UHD-Bluray player as well. Sorry about that.

I don't think that's the problem, it's just not specified in the link what the exact HDMI 2.0 version is...my TV is also specified there as being just HDMI 2.0 without the "a" or any other extension, but it auto-switches to HDR on the HDMI port Mini monitor 4K is connected to, also Dolby Vision, HDR10+ and HLG signalling is passed from other compatible HDMI devices ...

Incorrect specification adds the possibility of unnoted hardware revisions to all the other speculations. Decklink Mini Monitor 4K has been outputting HDR for me without issue.

The op posted also posted a screen capture of recommended settings from a Preferences page showing "global and default settings" for Output Pixel Format 10 bit RGB which I can't find. This has been a question in the past just what the output pixel format for the Mini Monitor 4k is, the prior conclusion (for 4k) being 10 bit 422. RGB would of course be 444 as noted for the selected 1080p, but I'd like to see this shown in some place, if it exists.

@Tom Roper: those settings you refer to are found in Fusion preferences.
Video devices seem to default to 422 output when 4K HDR 10 or 12 bit is requested.
