MacOS Install via USB Installer on MacBook Pro with damaged display
crwdns2934249:0crwdne2934249:0:
I have a mid-2014 MacBook Pro 15" (Retina) with a damaged internal display. I use this system in clamshell mode as my primary desktop (it has fast i7 cpu, 16GB RAM, and 1 TB SSD, so it's super-capable). I have an external LG 27" HD display connected via HDMI cable to my Mac. I also have external MagicMouse and Magic Keyboard for this desktop config.
Now, I need to re-install a clean MacOS. The latest supported version for this system is Big Sur v11.7.9, so I have that MacOS installer on a USB thumb drive, per Apple Support.
So, to use the installer, I power-on the MBP while holding the Option (Alt) key. But this boot mode does not display anything on my external display. If I boot using Command-R (or its corollary key-combos), I get the Restore menu and Disk Utility, but Restore menu does not support installing MacOS from the USB drive.
How do I boot from the USB drive MacOS Installer and get this boot mode to display on my external HD display??

PS: A new OEM internal MBP display for this model runs over $500, so repairing that issue is not a feasible option.
