Intel UHD Graphics 770 HDR

[WSpamW]

I've got this PC ; https://www.dell.com/en-us/shop/desktop-computers/optiplex-5000-micro-form-factor/spd/optiplex-5000-micro/gctoo5000mffusvp?redirectTo=SOC It has the Intel UHD Graphics 770 . It's connected to my brand new, 2022 release,QE55S95BA screen. This via a HDMI Ultra High Speed cable. Now the problem is I can never tell my PC (Windows 11 64bit) that the display is HDR capable. Always grayed out in Display settings. I've updated all my drivers via Dell Command Update, didn't help. What else should I check?

WSpamW, Thank you for posting in the Intel® Communities Support.

In reference to this scenario, in the link below, you will find the "HDR White Paper" that describes the system requirements in order to be able to use that option, which includes the usage of HDMI version 2.0 TV and/or DP 1.3 monitor:

https://www.intel.com/content/www/us/en/support/articles/000025998/graphics.html

According to Samsung specifications, the monitor QE55S95BA supports it, still, I was not able to establish if the HMID port on this product is 2.0 or higher:

[Alberto_R_Intel]

WSpamW, You are very welcome, thank very much you for providing that information.

No problem at all. Based on the fact that your computer seems to comply with the system requirements to be able to use the HDR feature, we will do further research on this matter to attempt to find a possible solution for this scenario.

In order for us to be able to do that, once you get the chance, please provide the SSU report, since it will allow us to verify specific details from your machine, like the graphics driver version currently installed, the BIOS version, memory RAM, SSD /HDD, specific Windows* version, in the case that we have the option to try to replicate the issue in our Intel® lab:

https://downloadcenter.intel.com/download/25293/Intel-System-Support-Utility-for-Windows-?product=91600

Could you please provide a screenshot of the Display settings where it shows the option is grayed out so we can verify additional details on this section?

If you prefer, I can always send you an email, for you to reply back to it with the SSU report and the screenshots in order to keep them private.

Regards,

Albert R.

See attached stuff.

I didn't make the screenshot for the display settings, will do it later. 

Hope you have a great day!

[Alberto_R_Intel]

WSpamW, Thank you very much for your response and for sharing the reports.

In order to rule out a possible hardware problem with the processor itself, please install and run the Intel® Procesor Diagnostic Tool. It does an overall test on the unit and if it passes the test it means it is working properly:

https://www.intel.com/content/www/us/en/download/15951/intel-processor-diagnostic-tool.html?wapkw=intel%20processor%20diagnostic%20tool

Accroding to the information shown in the documents, as you mentioned, the graphics driver version currently installed on your computer is 31.0.101.3790, provided by Intel®"

https://www.intel.com/content/www/us/en/download/19344/intel-graphics-windows-dch-drivers.html? 

It is important to mention that the Intel® graphics drivers are generic and they might or might not work as expected with your device. Based on that, we always recommend to install the graphics driver provided by the manufacturer of the computer, since that driver was customized by them to work with your specific platform.

I looked on Dell's website and the latest graphics driver version they have available is 30.0.101.2079, A01. Even though you mentioned that you already tested many different driver versions, if you haven't, for testing purposes, please try a clean installation of that driver following the instructions in the links below:

https://www.dell.com/support/home/en-us/drivers/driversdetails?driverid=yyn2j&oscode=w2021&productcode=optiplex-5000-desktop

https://www.intel.com/content/www/us/en/support/articles/000057389/graphics.html

We also suggest to get in contact directly with Dell support to confirm that the latest BIOS version is currently installed in your machine or to gather the instructions on how to update it:

https://www.dell.com/support/home/en-us

Once you get the chance, please let us know the outcome of trying the steps above.

 Intel® Procesor Diagnostic Tool --> complete pass. All good

Updated to the newest BIOS version, released 19/12/22 

Installed the Dell provided video driver, 

Here some more screenshots

So as you can see, the PC still doesn't understand the TV is capable of HDR. 'not supported'. I suspect it's something to do with colours (lower bit needed?) but I don't really see where to set this. 

Thanks for all the help, I hope I'm following your instructions correct

[Alberto_R_Intel]

WSpamW, You are very welcome, thank you very much for sharing those details and the pictures.

We are sorry to hear the issue persists after following the instructions provided previously.

Based on that, we will do further research on this matter, as soon as I get any updates, I will post all the information on this thread.

Hello WSpamW, I just received an update on this matter.

After reviewing the case, we determined that the reason why you cannot use HDR is because of the bandwidth that is available on your platform.

Trying to reach 4096×2160@ 60Hz/12 bit color needs a high bandwidth.

HDMI 2.0 max effective bandwidth is 18.0 Gbps and that might not be enough to be able to use HDR. In the following link, you will be able to find further detail about this topic and a bandwidth calculator.:

https://www.intel.com/content/www/us/en/support/articles/000023004/graphics.html

As an option, we suggest to attempt to reduce the resolution to try to reach the best one, based on the video capabilities of your machine.

Once you get the chance, please let us know the results.

[WSpamW]

Thanks for the continued support

I've lowered the resolution and this enables me to increase the refresh rate to 120 hz. Which is handy but not what I want.

The colours, I still see no option to change this.
Could you tell me where you would expect this setting in Windows? I check in Windows Settings --> Display & in Intel Graphics Command Center.

HDR is still not supported according to Windows.

So I can't say this is solved yet. I do think we're on the right track.
Unfortunately my Optiplex 5000 only has the HDMI 2.0 equivalent output, HDMI 2.1 is still too early for this machine. 

[MUC]

No, it's not to early for your machine for HDMI 2.1.

You can use a DisplayPort 1.4 > HDMI 2.1 converter cable als suggested. This cable contains the Synaptics VMM6100 protocol converter chip. If I get 4K@120Hz HDR 10-Bit Color Depth on HDMI connector side with the same chip by using an Intel NUC 11th gen processor launched Q1'21 as source then you should get it too with your 12th gen device. Please try this. The converter chip transforms DisplayPort HBR3 video (and audio) signaling to HDMI Fixed Rate Link (FRL) suitable for your Samsung display device. Please refer to the instructions below.

My result:

[WSpamW]

Thanks for your reply, that is hopeful. 

Would this cable be good? Seems correct but I don't see this convertor chip or HDR specificially named .

Does have enough bandwidth though, more than my current setup

[MUC · Accepted solution]

Yes, this is good. If you look at the manufacturer's website:

https://www.4xem.com/product/4xems-1m-8k-and-4k-displayport-to-hdmi-cable-copy/

In "Specifications" they say: Chip ID Synaptics VMM6100.

The current firmware is 6.05.120. If you buy this cable and it is not operating as expected you can do a firmware update to the cable when it is plugged in.

[WSpamW]

Does the length of the cable matter? If it's 2 meters instead of 1 meter, can this hamper with the signal? 

Thanks so much btw, I'll order such a cable and hope for the best.

[MUC]

The length does basically matter. But if 1 or 2 meters will make no difference. I've tested 1,8 m and 3 m and it worked. It should not be longer than this but vendors don't even offer more length since they know that this is critical for converter cables. If possible one should always use a cable instead of an adapter. An adapter with a socket where a separate cable has to be plugged in may cause more signal degradation due to longer traces and multiple connectors in the path.

[MUC]

You can try this:

Product	Connection	Chip Type	Current Firmware
Cable Matters 102103-BLK	DisplayPort > HDMI FRL	VM6100	6.05.120	Firmware Update

It worked for me establishing a connection between DisplayPort output to HDMI 2.1 FRL input with 4K@120Hz HDR 10-Bit Color Depth. This would be the maximum capability of this Samsung display device.

[n_scott_pearson]

I would also add that there are a lot of absolute garbage cables out there, with crap (or missing) insulation, crap connectors that break easily, etc. Remember, you get what you pay for - or not, as the case may be.

I have a rule: If the cable came with a monitor, it is, by definition, cheap crap and should be discarded.

[WSpamW]

Ok the cable finally arrived and it looks great. 4K, HDR is recognized in Windows 11, I can go upto 120 Hz, just like the TV supporrts. Great! 😄

Now, this Active Signal Mode, how do I change it? Seems like my PC isn't outputting on 4K yet, yet the display now is . 

But without a PC which is actively signalling in 4K, it's not done yet!

Thanks a ton btw, updating a firmware for a driver is new territory for me. Thanks for getting me 1 step further

[MUC]

Please try as follows:

1. Click the Display adapter properties link shown in your picture above. If you use more than one display, select your TV from a drop-down list at the top of the window.
2. The system will open a window with your GPU properties from the classic Control Panel. Click the List All Modes button.
3. Select desired resolution in the next dialog. Note that Windows lists a single resolution several times with different refresh rates. Make sure you pick the right one.
4. Click OK to save your changes.
5. Click OK to leave the property window.

If changes don’t take effect, then it may be useful to repeat the steps above using another resolution and then again repeat the steps reverting back to 3840 x 2160 @ 120 Hz to “synchronize” the Desktop Mode with the Active Signal Mode.

[n_scott_pearson]

@WSpamW,

Your problem could simply be that Windows thinks 4K is too hard to read (or something just as asinine) and is applying a scaling factor. Go into the Display Properties Settings page and check that the Display Scaling (in the Scale and Layout section) is set to 100%.

Hope this helps,

[WSpamW]

Thanks guys, it kind of works. It's a bit flaky, sometimes the PC forgets about it and I need to adjust the settings again. 

Not super userfriendly that way but maybe I'm asking too much. Pretty happy overall

Thanks for all the help!
