Cable Matters 8K Unidirectional DisplayPort 1.4 to HDMI 2.1 Adapter

I've been through at least 5 displayport to hdmi adapters over the last month and ALL have failed to output 4K @ 165hz. Sure they can do 120hz with VRR, but not 165hz. THIS adapter actually does exactly that, and very much more cleanly than all the other dapaters I've tried. No visual glitching or cut outs, it just works. The only downside is lack of VRR, but it seems to be alot more stable because of this. Cable Matters have clearly developed a superior chip here. Hopefully in future they'll develop a VRR capable version, but until then, imho, this is the best Displayport to HDMI adapter on the market.

Works well so far on my set-up an HTPC with Madvr linking the graphics card display port to a fibre optic hdmi cable to a 4k 60hz projector.

Well I took a chance. Finding a display adapter/cable that could display 120 hz - freesync - HDR on Linux is not easy. VRR included. My previous cable which was DP to HDMI was causing issues and wasn't working properly. My TV has 144hz and is a great display but no Display Port and HDMI standards have ruled out HDMI 2.1 coming to Linux. My TV is basically a 55 inch monitor and with this adapter - it brings everything that is blocked to those of us with perhaps a 7900 xtx AMD card (which I have) to life. I now have a stable display at 120hz and the TV reports that Freesync and HDR are working. I have confirmed they are working and the display looks superb. HDR now fully functions and it's awesome. I have the TCL C6K and it now rivals OLED in contrast and colour reproduction. Previously my display was 120hz with the older cable but HDR was washed out and not functioning properly. VRR was causing blank screens in games and it was unusable. VRR is now working perfectly. This is a must for Linux users. Spread the word.

Doesn't work for ps5. I have a 240hz monitor so don't waste your time buying this for ps5 pro

I bought this for the purpose of being able to use 4K 120hz on my LG C9 with a GTX 1070 to play some Older Games in crisp 4K and it worked straight out of the box for me. All I did afterwards was enable 10 bit colour in the Nvidia Control Panel, as well as enabling HDR when I need it for certain games ( HDR works great with the adapter at 4K 120hz ) . The only issues I've had with the adapter is the screen can sometimes cut out when exiting a game ( Hasn't happened often ) or when using Custom Resolution Utility to setup 1440p which requires a restart to get the image back, GSync also isn't supported with the adapter either. But other than that, couldn't be happier with the result.

Disclaimer: 4k 120Hz is not supported out of the box, it will require manual tweaking The process of enabling it is straight forward and requires less than 5 minutes of work. You will require a Windows machine with a DisplayPort to plug in and flash the adapter. The firmware and instructions are found online after searching: DP/USB-C/Thunderbolt 3/4 to HDMI 2.1 4k@120hz RGB4:4:4 10b HDR with Apple Silicon M1/M2/M3 now possible ! The Cable Matters USB-C to HDMI 2.1 solved all my issues. I've long wanted to embrace the one cable life with my Macbook but always had to compromise. All docks I've come across are limited to 4k 60Hz when connected to Macs just like the HDMI port on the device itself. This adapter was outstanding and singlehandedly resolved my issue. Using the firmware update tools and an older firmware version I was able to utilize the DP 1.4 port on my dock and display 4K 120Hz HDR to my TV. If you're planning to replicate this, for the smoothest experience ensure the adapter is the 102101-BLK model and you're using a certified HDMI 2.1 cable. The build quality on the adapter is great, even though it's made of plastic it is durable and doesn't get as warm as other adapters. Highly recommend this adapter!

IT WORKS!!! 4K120Hz VRR/FreeSync HDR 4:4:4 RGB works on Linux and Windows on my Radeon 7900XTX. Tested on Samsung TV Q90A and Hisense TV U7KQ. Just a small warning that you must use Firmware 7.02.120 specifically and non other. If you have any problems you can try to disconnect and reconnect. There is some luck involved it seems but I've got very lucky with both TVs on Linux and Windows. I had some problems at first but it worked out at the end. Removing and power draining can help. Added screenshots for confirmation.

I have been using the item for 3 days now and works great at 120hz, but make sure you flash the latest firmware first to 7.02.123 the adaptor will get warm which is perfectly normal but won’t be hot to touch, I guess this is because it processing DP to HDMI signals. I have tried CB 102103 and the Ugreen 8K cable DP to HDMI and they both work but they will heat up very quickly on the HDMI end and the screen will start to flick and lose signal. It got so I hot I thought the cable might melt, so I sent them back I hope this helps everyone.

Le plus cher sur Amazon mais fonctionne parfaitement. J'ai un long câble HDMI qui traverse la pièce pour aller du PC à la TV et avec les autres adaptateurs DP vers HDMI l'image se coupait régulièrement. Avec celui ci aucun soucis. Testé entre un PC et une TV OLED LG, la 4K fonctionne et le HDR est reconnu. Je n'ai pas poussé les tests plus loin car c'est juste pour regarder des vidéos.

Funziona perfettamente in 4K 60Hz insieme al cavo "HDMI 8k 20M" di Ubluker.

I little bit expensive compared to other offerings but it did save me from buying a new GPU.

Does exactly what it says on the tin!
