49" Neo g9 hdmi issue

[gthin]

Hi 
I've got a 49" Neo G9 which connected to my ps5 and it was working fine as i can play games at  120hz  on this monitor without any issues. But all of a sudden monitor is not recognising the ps5 input if the hdmi version from monitor menu is 2.0. Now i can only see something on monitor if i downgrade to 1.4 which limits the 120hz refresh rate on monitor. Most of the options are greyed out now in the monitor menu.  Please note that i haven't changed the cable or anything. I was playing around with the monitor menu to see whether i can fix it but unfortunately nothing worked out and even contacted the samsung support they said they have never seen something like this before and will refer to some technical team. I haven't heard anything back from them after. 

Has anyone experienced this before or any solution that would fix this issue?

Hi, same situation, still not found new firmware does not exist, also have 1.4 and 2.0(arrow up) in monitor menu, also cannot stay in PS5 VVR mode - unsupported monitor. But on all review all inform me that that monitor have HDMI 2.1 and support VVR on PS5, also in my monitor not working CoreSync - it's RGB LED flashlight on backside of monitor. Also in menu in gray color.
