DELL G2724D works fine with DP-but less good with HDMI

[atiiis]

Hello Guys.

recently bought a new monitor, because I have a fresh PS5 as well, after a really active search for the best/budget monitor I decided to buy the DELL G2724D which has VRR support over HDMI. RTNGS listed it as the best budget monitor for ps.
Well it seems its only working on paper, and if I play on my monitor, for ex EA FC 24, it has HUGE input delay, I was really frustrated so i tried to connect it to my TV LG 55UK6500MLA (more than 5 years old), and its working just like FINE, i mean its perfect, no delay, no stuttering, smooth as hell..
but when i play on monitor everything goes bad, its really annoying.

what can cause the issue?
i have console mode on (you can only activate VRR when its on)

I use my PC via DP on the same monitor and its working fine on 2k 165hz at the same time, I dont know if this can cause any issues.
really appriciate any idea.

thank you!

Test the HDMI port using your PC and see if the issue persists or not.
