Recommend a DisplayPort 1.4(a?) to hdmi cable or adapter

I need a DisplayPort to hdmi adapter (preferably) or cable. It needs to be hdcp 2.2, 4k 60hz and hdr compatible. I've been looking at a few on Amazon but the details are sketchy (to say the least) and half the time the questions/reviews appear to be for totally different products to the one on sale.

Can anyone suggest one which can do exactly what I need?

I'm not sure about the HDCP 2.2, you will need to look into the specs, but they meet your other specs and more importantly as many of the reviews indicate, they work without issue. I certainly found this to be the case after buying/trying at least 4 other types with only varying degrees of success.

Hi. Thanks for the recommendation. Unfortunately that adapter only does 4k @ 30hz.

ah ok sorry, but good luck with the search, however it is possible they do a higher spec model for a bit more money that does what your looking for... worth a look

The DP standard isn't public and I'm struggling to find the information about what is supported by dual mode in DP 1.4.

Although given it pre-dates HDMI 2.1 there's a good chance it only officially support [email protected] if you drop the colour resolution by using YPbPr 4:2:0. If you're just using it for video that may be acceptable as they're generally already compressed that way.

But anything else and you may want to shell out the extra for an active adaptor. Something like the Club3d CAC-1085.

I'm just looking for a cable or adapter which I can extend my 4k hdr pc monitor to my TV or receiver for home cinema duties, supports HD surround sound passthrough and which supports hdcp 2.2. I've tried a few so far which claimed to do this, but which failed at the hdcp hurdle. It's soul destroying when you order yet another device which doesn't live up to its hype, and then have to start arranging returns etc.

this does not make sense

extend (my desktop from) my 4K HDR monitor to my TV

Club3D are a Dutch company and their products are sold through much more specialist and knowledgeable shops than Amazon, so I'd expect their claim of HDCP 2.2 support to be more likely to be true than some random chinese seller.

I don't have personal experience though. The only DP to HDMI adaptor I have is passive and only driving a 1920x1200 display.

I agree with with you on the HDCP 2.2 but if he is extending his desktop to his TV, (I think this is what this all means) then why not just get an HDMI extension cable?

What graphics card do you have? Assuming your using the DP for your monitor (and have more than one). Are you saying your Graphics card has no HDMI out? that would indeed be rare. I am yet to encounter a card that doesn't have one?

Maybe I'm missing something, but the original post is unclear anyway.
