External monitor not displaying anything but OS see's the monitor

========================
Detailed description： I just received my brand new F15 (2022). When I connected it to my LG UltraGear monitor, the Operating system knows the monitor is connected. It shows up in the display setting and the Nvidia control panel but, I get no output to the monitor at all. If I open an application, of course, it opens on the monitor that I have no output on. I purchased a brand new cable that I have tried on my TV, PlayStation 4, and Xbox and it works perfectly. I have connected my monitor to my old desktop through HDMI and the monitor works fine. I connected the laptop to the monitor and unplugged the monitor hoping the power cycle would fix the issue, but it did not. I have updated all drivers and the BIOS to the latest version available and uninstalled and reinstalled the drivers to no avail. The laptop has the Nvidia 3070 RTX video card and I scoured the Internet for answers. I need some help with this issue, please.

Thank you

@MikeS
Do you have other HDMI cables that can be exchanged for testing again?
If you adjust the screen resolution, does the situation improve?
