Multiple replies here:
1. I did convert a laptop display in the past, and while it was a fun project, the cost and the "ugliness" of the finished product makes this route not suitable
2. Projectors came to mind, but they are bulky to carry and not everywhere has a clean wall I can use, again, my goal here is "crash cart scenario"
It worked.. "OK", niot great, my main complaint is that the USB-C connection is a hit or miss, it worked on an Android phone for example, but it did not work on my souped up Dell/Windows laptop, and the support response is "just use USB-C for power and use the HDMI for display". Yup, it's going back.
I think I'm just going to drag my beast to CanadaComputers and test things with them before buying anything.
Thanks for all the responses
