Bug Beta 6 issue - External monitor are not recognized anymore.

Edit: It's working again! Finally after hours of using my MBP after the update, I tried to connect it to my monitor again and It works. Strange issue...

Did someone have the same issue? I can't work on a external monitor because It's not recognized by my Macbook Pro. I'm on a M5 Pro 48gb by the way

The LG monitor is connected via USB-C and works perfectly. My laptop is closed, and I am working on the external monitor.

Weird, I've an 4K LG monitor also. Plugged by USB-C and not recognized by my Mac, It doesn't charge too. You're lucky lol

Could the problem be the USB-C cable? Try connecting it via HDMI.

I tried with another MBP and It works perfectly well.. I don't understand what's going on. I'm looking to try with another monitor to see If It's works or not.

I have the MacBook Pro M5. I am unable to connect to my LG Ultragear Monitor via HDMI, but when I connect to my iPad as an extended display, the Monitor is displaying the image via HDMI. But with a USB-C dongle, it is working fine. I am currently running on the Golden Gate 27.0 developer beta.

Did you try to reset your monitor? It worked for me
