    Not really no, because HDMI 2.0 has 18GB/sec vs Display port 1.4 11GB, but also this is being used at 60Hz so both can provide enough bandwidth. The problem you have with Gsync it can only use display port but it's not really the issue we are seeing here since HDMI 2.0 is being used.

    dp1.2 has 18gbit
    dp1.4 has 32gbit

    Hmdi2.0 has max 18gbit, real 14.4gbit
    Hmdi2.1 has now theoretical real 42.4gbit

    Yes it is. Almost 10 months worth of driver updates improved the perf a lot. Even the difference between 18.6.1 and 18.7.1 is around 5% on average. For many games had driver optimisations since also, some 20%+

    Hasn't AMD hardware & drivers been processing the equivalent of HDR internally for years now before downgrading to display? Shouldn't really impact AMD cards at all beyond margin of error for benchmarking.

    Doesn't have to be. Nvidia used to win tessellation tests quite easily because they were stronger at that. AMD even had to make a slider to cut down on the tessellation levels to keep up, not that it really mattered that much because not all games had tessellation at all but I do remember Crysis 2 taking a huge hit on the AMD card I had. (The tessellation addition was sponsored by Nvida though).
    Same is true here, how many have HDR screens? By the time they become more common Nvidia will put in extra effort to catch up.

    it is not as easy as that...

    AMD and NVidia don't use the same way to render the same thing... it's like comparing an american muscle car with a german hybrid GT both do the job, but not the same way.

    i agree.
    but as 4K display are on last year 1080P s price, HDR shouldn't be too far either in term of mass production... we will see.

    Interesting findings.

    The thing that puzzles me about this whole HDR craze is you can pick up a 55" LG 4K HDR TV for less than $400USD, but when it comes to a PC monitor, HDR is a $500+ premium. What a joke?!

    It's the single-most over-priced feature on monitors these days. It even beats the premium people pay for G-sync. Pure ridiculousness.

    Again, this isn't an issue. As long as the display is using RGB Full @ 4k when rendering HDR and it is set as such in the NVCP ( Which I posted in my previous reply.) there is no performance loss.

    You can find some good ones out there for not too bad. I got this one recently on sale for $440 and it's been great, granted the HDR implementation isn't the best out there: Acer XZ321QU. It's basically a Predator, however it has HDR instead of Gsync which was a bigger deal to me. Although it's HDR isn't the best out there it looks amazing when I have it turned on and is well worth it. I'm still surprised to hear it takes an FPS hit, although I haven't noticed it myself.

    Well, for instance on my 800euro Philips 55" 4k HDR TV it does not support the same color levels, 4:4:4 as my monitor does despite the monitor being 8bit and the TV 10bit.
    And when I scroll the text I can see more problems with the text for instance, it's not as high quality as the monitor on many levels.

    Yup the premium the manufacturers are charging is absolutely absurd and straight highway robbery.

    Interesting, my Vizio P55-C1 displays no such issue when scrolling web pages etc, I actually finally have a screen I prefer to my ASUS VG278H which came out in 2011

    but but but . . .RTX ray tracing!

    idk, it's like nvidia doesn't care except w/their own tech. i'm sure when the HDR adoption rate increases, they'll consider looking into it.

    until then:
    oh look! gameworks!

    There is only one important thing to note... Less than 60fps on average and dips to pretty low fps. 4K HDR is not for high end cards.

    It takes some time to notice this, and perhaps my setting was slightly wrong...but I don't think there is any TV that matches a proper monitor. It also seems harder to get a TV with no black light bleeding compared to monitors, or perhaps I've been lucky.

    ?

    You can't use RGB with HDR . you can't use Full Range with HDR . you can only use YCbCr 4:2:2 with LIMITED when using HDR . Also Dolby vision is only 4:2:0 LIMITED , so I don't understand where did you get this information . Also that's what Nvidia Automatically is doing . if you don't HDR signal won't be working on the TV or monitor
