SER7 HDMI 2.1 Probrem! Monitor disconnects at random times

n-kase · Post time 2023-11-13 17:41:15

There is no problem when connecting with DP, but when connecting to the HDMI 2.1 port with the ultra high speed HDMI cable, it disconnects irregularly.
Irregular disconnections occur only when the refresh rate is 144Hz or 175Hz.
I think, The refresh rate needs HDMI 2.1 speed.
Does anyone know if the SER7 can be properly connected to a monitor with HDMI 2.1?

I would like to enable VRR and use it at 144Hz.

My monitor is "MSI MEG 342C".
The resolution has set to WUQHD (3440x1440).
I'm using the Ultra High Speed cable that comes with the monitor.
and I've checked the cable coming with SER7, but it's unstable, too.
The cable comes with machine is labeled "High Speed HDMI Cable with Ethernet".
Probably, it means HDMI version 1.4.

Can the SER7 be used with a monitor connected via HDMI with a resolution of UWQHD and a refresh rate of 144Hz?

I have a SER7 running on a Dell 3223Q 4K HDR and can run this without issue at 144Hz @ 4K, I usually run @ 120Hz but have been running for a few hours now @ 144Hz just to test without issue. I'm using a good HDMI 2.1 cable.

I replaced the monitor as initial failure.
It works fine now.
