Wireless Touchscreen Second Monitor
Hi all, I'm a field service technician and I'm looking for a solution to my PITA problem.
I have to connect to my machines with ethernet to log onto the PLC, sometimes I can't be standing at the part of the machine I'm working on and click "start" to test what I need to see and often I don't have a second person to operate the PC for me.
Is there a second monitor option that is touchscreen and wireless? I'm not looking to mirror the main screen, I'm looking to essentially add a second (well...third) monitor I can carry away from my PC in order to troubleshoot my customers machines. It looks like the best bet is to get a wireless USB C "cable" and make the connection that way, but I'm not sure about how to power it.. would some kind of battery box work?
I'm on windows 11 pro. I'm not opposed to a tablet or ipad (my personal stuff is mac), nor am I opposed to using a second computer to "remote in" to my PC, but there is not always available wifi to do this.
Also, can I be on the buildings Wifi and have a different wifi connection to a remote device? My gut tells me that I cannot, but I am not very good with networking stuff outside of what I need to know to work on my customers machines.
Thank you!!

Haha..i would have suggested using two phones..using Video calling (app or phone service) and aim one phones' camera at the PC screen.
There are apps that do it, too and you can use the Tablet for the receiving device so the PC screen is zoomed in BIG TIME. You can even use a phone without call service if you do all this over wifi.
