USBC-6950U - Two monitors flickering, overheating, with MacBook Air 15" M2

Hi there,

I’m using a 2022 MacBook Air 15 inch (M2 processor) with the USBC-6950U to run two Philips Monitors (Model ID 276E8VJSB/75) via HDMI

When I connect initially, everything works as expected. After about 30/60/120 minutes though (depending on the day) the screens start to flicker and eventually stop working.

I had tried different HDMI’s - eventually getting brand new ones. I used different USBC ports on the Mac. Still happens.

The Plugable unit itself, gets VERY hot, and I started to experiment with keeping it elevated, having a fan directly on it, etc.

When the fan is on it, it does help extend the duration of use, until it stop again.

I then need to wait until it completely cools off, to start again. I’m not sure what else to try here
