Thunderbolt interface to MacBook M5 screen goes black for a few seconds

I am using your docking station with my macbook air m5. I use a LG monitor with 60GHz refresh with HDMI while my Mac is connected via the provided thunderbolt cable. While working throughout the day every now and then the screen goes black losing all video. Audio continues. What is the problem here? Is it bad docking station?

Hello Sakid,

I noticed that you reached out to us directly over email as well, so I will be continuing conversation there to avoid redundancy.

Thank you,
