After I had my macbook update with latest OS, I can not connect with my monitor

On connecting with my monitor, my mackbook is freezed.

I tried to reset NVRAM and reset the SMC. However, it did not worked :-(

I have a old LG monitor and that is working well with my macbook.

Unstable monitor connection MacBook Pro Hi guys, I use my MacBook Pro (13-inch, 2017, Two Thunderbolt 3 ports) with two external monitors. USB C -> HDMI cable and HP EliteDisplay E243 monitor. I always have a stable connection from Thunderbolt port 1 and an unstable connection from Thunderbolt port 2. The monitor connected to port 2 blacks out every once in a while, and sometimes the monitor stays black. Only way to get it back to function is to disconnect and connect the USB C cable. Any idea why, and how to solve this issue?
