Mac Studio Ultra + LG 43UN700-B = Headaches

[cloudnoize]

I recently got my Mac Studio Ultra and I'm using an LG 43UN700-B monitor. Great setup, except, every time I boot the Mac from being turned off for a while, it seems the LG monitor doesn't wake up and the Apple logo and status bar don't show, so basically a black screen. I have to physically pull the USB-C cable out of the Mac Studio Ultra and then push it back in again to see my desktop. I've also tried multiple USB-C cables and it's still an issue. It works well when using it with my 2018 Mac mini. Being an M1 Mac, does this pose a problem? Thanks!

Have you tried using HDMI?

I have tried an HDMI cable as well and I'm still getting the same result. The strange thing with either USB-C or HDMI, if I restart the Mac (under the Apple logo), I will see my Login page asking me for my password but I won't see the Apple logo/Status bar. If I leave it shut down all night until morning and boot up the Mac, I won't see either Apple logo/Status bar OR my Login screen. The screen remains dark. Thanks.
