Hi Remi,

Please keep it English on these forums 🙂 (Thankfully to Google Translate I can help I hope).

Have your tried connecting with a different cable other than the “HDMI 2.1” aoc cable? See if that works?

What HDMI2.1 AOC cable do you use?

Hello, thank you for your answer. I am using a CABLEDECONN 8K 2.1 Optic 30ft cable and it ‘s not working. actually with another common 2.0 cable it works. i need this adapter because the hdmi port of my graphics card is screwed up … so, it works in 1440p 120hz HDR. at first glance it’s cool that I didn’t need a higher resolution! but i have two problems which are very big for me. the adapter is not g-sync compatible, and in addition to that the sound does not work in 5.1, in dolby atmos either, and even in stereo I cannot exceed 16bits 48000Hz. disappointing all the same ….

Hi Remi,

I read a lot of bad reviews regarding that cable with the combo of hardware you have. I’m pretty sure the cable is at fault here. Also on the Club-3D site it’s pretty clear that you should use a cable no longer than 2 meter. And if you really want to try with AOC, try a cable that is at least certified by HDMI for HDMI2.1. Like the CAC-1376, but I don’t recommend it.

The adapter never supported G-Sync and this was never claimed or stated anywhere.
