Asrock arc 770 phantom gaming not getting above 4k 60hz

[Totaledm]

i got my asrock arc 770 phantom gaming 16gb today but i cant go over 60hz on 4k. i get that i can change to 120hz 4k but as soon as i do no signal... disturbing!!

gpu has hdmi 2.1 support for 4k 120hz.. displayport 2.0.
i have displayport cable 1.4 to hdmi 2.1 still can't get over 60hz on 4k... i can't even go over 60hz anymore with qhd 2580 x 1440p.

displayport cable 1.4 to hdmi 2.1 works at 144hz 4k with igpu at 11600k i5 without problems.

Can anyone tell me what is wrong? I have a Lg 55 qned nanocell 120hz tv 2023 model with two 4k 120hz hdmi 2.1 connections...

i have found a way around the problem, i get to run with igpu at 4k 120hz until intel fixes their problem with arc770.

I'm disappointed in intel properly!

so intel fix this by the week immediately..

I'll wait until I fix this or I'll return it!

Since intel where late to respond. Asrock said, the card needs return to the dealer because something is wrong with the card.

Now its to late, I did buy Gigabyte Radeon RX 7800 XT 16GB Gaming OC instead.

Fix your issues with arc..
