This is the second time that I buy a type c/display port to HDMI 2. The first one was
ULT-WIIQ-US 6.6ft, DP 1.4a to HDMI 2.1. Unfortunately, this cable had audio issues, it stutters every 30 seconds and after 4 days it stopped working on 4k 120hz RGB. I researched a lot on these adapters and I found out that my RTX 2070 support type c video out display port alt mode, so I searched these adapters too. It seems that many of these adapters suffers from overheating, signal loss when switching in and out of HDR. Also, some of them require USB power. It seems the most of these adapters use the same chipset, but, it is the firmware that cause these issues. Then I saw that Cable Matters provide firmware update for some of the display port/type c to HDMI 2.1 that mention many bugs fixes related to issues that I mentioned. I decided to buy the short adapter and buy a hdmi 2.1 cable instead of the cable type, as the adapter is more expensive than the cable and it reduce the chance for it to stop working properly. The longer the cable is, there is a higher chance for failure. As soon I got it I download the latest firmware update from Cable Matters website and saw that the cable is on older firmware, so I update it . It takes very short time, and it works without issues. I can send HDR signal without losing signal, the audio does not have any issues and as I wrote in the title, it works on 4k 120 Hz 12 bit RGB. I will update the review if the adapter will fail.

Great stuff
Yes, turns out it supports 4k/120. However, the firmware is not on the cable matters' website, but on macrumors.Google for "macrumors HDMI 2.1 4k 120 VMM1700", there are (custom?) firmware for the VMM1700 (chip model), flash in the "VMM7100_4kRGB120hz10b_V7_02_112" firmware.Then, activate the 4k120 10bit mode from the open source display driver "BetterDisplay" as the screenshot above. It works perfectly.

HDR -> OK
120hz -> OK
12bits -> OK (ouai même le 12bits dans le panneau de contrôle Nvidia est sélectionnable en RVB). Faut-il encore avoir une TV en 12bits. Perso, j'ai laissé sur 10 bits
Par contre, quand je met le G-Sync, dans les jeu, l'écran s'éteins et il recherche une source. Donc faut zapper direct le G-Sync (mais franchement G-Sync, on s'en fou un peu, je préfère avoir du 120hrtz en 4K que d'avoir G-sync...
Un problème par contre, c'est le son qui fait un peu déconner l'affichage, souvent l'écran passe en noir et se remet. J'ai donc désactivé le son de la télé dans le panneau de contrôle et ça fonctionne nickel. Le mieux restera une carte graphique génération HDMI 2.1 mais pour le moment on va se contenter de ça.
Pour ma carte, c'est une 2080ti Aorus 11G, il est clair que si vous voulez faire du 120fps sur cyberpunk, ça va pas le faire du tout avec cette carte, mais des jeux style crossout, c'est 120fps constant et l'image est superbe avec une TV MiniLED
Donc voilà, si vous voulez pas changer de CG pour avoir la 4K@120hz et que vous avez une Geforce série 2000 avec le port usb-c à l'arrière, foncez prendre cet adaptateur ! C'est pas cher pour résoudre le soucis =)
