At least, not if it uses the same display tech as my laptop's screen. If the angle is just a few degrees off vertical vis-a-vis my eyes, then I see a very heavily-shadowed image.

An overhead projector such as the DIY project in the youtube video uses would probably be best, if you're not going to go with a display that's expressed designed to be used in a flush-with-the-tabletop mounting.

BTW, if you go with an overhead projector, then you can avoid shadowing the map to at least some degree if you choose to use these particular minis:  https://www.kickstarter.com/projects/1534484023/flat-plastic-miniatures
