It’s an obvious tip when you think about it, but in actual practice, when I am called in to build a simulator and the client has already purchased the hardware, inevitably the selected monitors are not identical.
There are two other tips that are relevant:
In the old days it was necessary to remove the actual monitor from the plastic bezel, but nowadays it is possible to purchase monitors with very thin bezels like this:
The other tip is something you need to watch out for but is difficult to ascertain if you are buying online.
