Yes. I am holding off. I am waiting to see what the next generation Intel chips bring to the table.
are you sure you want to output HDR and not just HD ?
im sorry im so lazy here is a quote from another site about laptops and HDR output
""""""""""""""""""
How DO you output 4K @ 60 Hz and HDR (meaning HDMI 2.0b) from a Laptop?
The answer is...
Via the USB-C or DisplayPort connectors. Check your laptop manual to see if your USB-C port will work or not. This guide does
not cover the USB-C method, since I prefer leaving that port free for USB-C peripherals instead. However, the
DisplayPort output will
always work, as long as the DisplayPort output is rated as Version 1.4 or higher. DisplayPort is a much higher-bandwidth port than HDMI and is made for high resolutions. Just check your laptop manual or spec sheet to see if it's DP 1.4 or higher. The reason why you need DisplayPort 1.4 is that HDR was added in that version. Older versions (such as DP 1.2) have enough bandwidth for 4K @ 60 Hz too, but they will NEVER give you HDR output. You
must have
DP 1.4 if you want HDR support.
Also check which
type of DisplayPort your laptop has. Mini-DisplayPort is the most common, but there's also regular DisplayPort. The only difference is the size of the connector.
To connect your laptop's DisplayPort to the TV's HDMI, you'll need a conversion cable. There are passive and active conversion cables. Passive cables contain a small chip which tells the DisplayPort that it wants to output HDMI instead, and the chip also converts the DisplayPort's 3.3 volts to HDMI's 5 volts. The problem with passive cables is that converting 3.3 to 5 volts also puts high pressure on the chips. To be able to do that voltage conversion at very high speeds is problematic, and as of 2020, no manufacturer has ever designed a passive cable which can output 4K at 60 Hz. They limit themselves to about half of HDMI 2.0b's bandwidth to keep costs down.
Therefore, anyone who wants the full scope of HDMI 2.0b capabilities (up to 4K 60Hz, HDR, etc etc), will need an
ACTIVE DisplayPort 1.4
(no lower versions) to HDMI adapter. That's what you get in the renowned
Club3D "CAC-1180" (Mini-DP 1.4 to HDMI) and
"CAC-1080" (DP 1.4 to HDMI) cables. They contain a MegaChips MCDP2900 chip, which converts DP 1.4 to HDMI 2.0a. Yes, that's "a", not "b". But "b" is just a software extension which changes how HDR metadata is transmitted, and is usable with "2.0a" chips. So the chip
does in fact
fully support HDMI 2.0b. Club 3D are the most famous brand within the area of converting DP to HDMI, and their products are certified by the HDMI Licensing company. But there are also others that make adapters, such as DeLOCK, Lindy, etc. Many of the other manufacturers are sloppy and mislabel their product info. If you check any of them, be
very sure to research
carefully that the cables are
active converters that
MUST CONTAIN either a MegaChips MCDP2900, or a Parade PS186. (In the future there may be even higher model chips, but as of early 2020 those are the only two "DP 1.4 to HDMI 2.0b" conversion chips.) Any other/lower chip versions will NOT work. It must be specifically those two chips, or newer models of them in the future.
The two cables I mentioned above are very short dongles, with a male DP to female HDMI connector, which are intended for you to insert your own HDMI 2.0b cable into. Club3D also sells cables with built-in longer cables, but I
highly recommend getting one of these shorter female dongles (mentioned above) instead, because Premium High Speed HDMI is a very demanding cable type, and if you get the long version, there would be several meters worth of possible points where the cable could get pinched and break. You definitely do NOT want the expensive "active adapter" part to sit in such a long cable! By buying the short one, you ensure that there's only a very small portion that contains the converter, thus much less risk of that part breaking. And of course, having the removable cable version also lets you swap out the HDMI extension for an even longer one (up to 5 meters, which is the max recommended by Premium High Speed HDMI).
Personally, I went with the Club3D "CAC-1180" (Mini-DP 1.4 to HDMI 2.0b), as well as their fully certified Premium High Speed HDMI 2.0b cable "CAC-1310" (3 meters). Note that they have CAC-1310 (3 meters) and CAC-1311 (1 meter). I chose the 3 meter version. And I'm happy to report that I have rock solid 4K, 60 Hz, HDR output from my RTX 2070 laptop to the big screen TV!
You can see someone's review of the "CAC-1080" (the DP 1.4 to HDMI 2.0b version) here on YouTube:
Good luck with your own HDMI setup! You are awesome! :-D
(Addendum: Some laptops natively contain Intel's "LSPCON" video compression chip, which achieves HDMI 2.0a output from the processor's HDMI 1.4 output, by compressing the signal. Read this post for more details. You must therefore check your motherboard manual to find out if your laptop has that chip, or perhaps even has native HMDI 2.0 support, which was added as of the Intel Ice Lake architecture released in September 2019. If you don't have a LSPCON chip in your laptop, and don't have an Ice Lake or newer CPU, AND you also don't have any sort of sufficiently-modern USB-C/DP/Thunderbolt-to-HDMI2.0 dongle already included with your laptop, then you definitely need to follow my guide to get high-bandwidth output! Have fun!)
