Hello nhawk2,

thanks you for your question.

would you be so kind to provide me with the laptop brand and model number, then i am able to see what the specifics are with the particular model.

can you be a little more specific about the loss of metadata, im not really sure what you mean with it gets lost within the adapter?

hope to hear from you soon,

Kind regards

Dell Latitude 5285.
The TV shows when HDR10, Dolby Vision or HLG is active, but every mode with the laptop resulted in Normal (non-HDR) mode

Hello Nhawk2

Thank you for your reply,

as it seems your intel chipset should support HDR, but no where is mentioned that the output of the usb-c type port on your device support HDR as well. neither dell or any other sources mention this, so unfortunatly i am not able to give you a sound answer. HDR could be supported on your laptop screen but this does not mean necceraly that it can give that output by usb type-c. it is mentioned that the usb-c is 3.1 gen1 and has displayport but again nowhere it says what version of DP this would be. For HDR to work this output on usb-c should be a DP 1.4 port since i can not verify this i would advise you to contact Dell directly.

if you need any aditional assistance please leave me a message.

FYI

I have checked the following articles as a source.

I don’t know if it’s DP 1.4, but I went by this article written by Intel, which claims that Win10 RS3, Intel 7th gen CPU with HD Graphics 620 and DP or HDMI connection (with proper adapter to HDMI, such as Club3D specifically named there) should be able to produce HDR output such as HDR10

Can you review the article and let me know if I missed some requirement or need a different adapter?

Hello Nhawk2,

Thank you for the fast reply.

I have contacted Dell directly, unfortunately they have just confirmed the dell latitude 5258 does not support HDR output due to a hardware restriction. neither is there a work around by a software update.

this is also the reason why they do not advertise it or mention it in the manual.

Sorry to be the bringer of bad news, hopefully this answers your question.

have a good weekend.

Kind regards

When 5285 was released, HDR wasn’t really discussed (and Win didn’t support it) and thus Dell would have nothing in the specs that says whether HDR is supported or not.

Dell doesn’t implement some special pathways, etc.  That laptop comes with i7-7600U and HD Graphics 620, which according to Intel (who makes that hardware) DOES support HDR.  Furthermore, if HDR was NOT supported, then WIndows RS3 would NOT detect HDR capabilities for all 3 items (HDR video, HDR apps, WCG apps) like you see here (which 5285 did):

Hello Nhawk2,

I understand your frustration, however if you would like some aditional information please contact Dell directly. I am not able to rule against the manufactorer and neither is intel in the end Dell makes the statements, hope you understand that. Dell clearly stated that there hardware does not support the HDR output. they are able to choose for that due to hardware setup.

Again i would urge you to contact Dell directly.

Have a great weekend.

Hello Nhawk2,

thank you very much that is very supportive of you. this way we can keep each other informed and learn from one another.

kind regards

Got new firmware from support. So far, looks like it fixed the issues. Thus, all you need is a HD Graphics 620 and above, DP v1.3 and if course HDR10 capable TV.

Hello Nhawk2,

That is good news. May i ask if you would share the download link so others might be able to make use of the solution you found.

Again glad you solved the problem and you are able to enjoy the HDR.

Kind regards

alright that is good to know, thanks for sharing 😀
