Hey Manjaro Forum folks.
This is been driving me crazy. Finally figured out what works for me so I thought I would share my results.

PC is hooked up to a Vizio P55-F1 HDTV Max Res 3840x2160 60hz refresh rate. Initially I installed the latest NVIDIA driver 455.38.1 and every time i change the input on my TV HDMI and back to this PC HDMI input the screen won’t recognize it and the screen remains black. Also this happens when I turn off the TV and turn it back on. Researched HDPC compatibility issues and these didn’t bare fruit so I decided to revert back to older kernels to see if that would solve my issues like 18.104.22.168,22.214.171.124, and finally 126.96.36.199 and still the same even with 455.38.1 NVIDIA driver. Then I went back to kernel 188.8.131.52 and used the Manjaro Settings Manager (GUI) Hardware Config and uninstalled NVIDIA 455 and installed 450 and now no issues. I noticed that when you uninstall an NVIDIA driver it wipes out the /etc/X11/mhwd.d/nvidia.conf file and any settings you may have made. Since it wiped out the old nvidia.conf I thought maybe i could reinstall the 455 driver and that may work but what ever i try the only one that works is the 450 driver.
Just thought I would document this in case someone else is going through this.
I even purchased an HDMI switch from Amazon so maybe if it was do to HDPC issues but now I know its software.
Thanks Great work Manjaro Team.
