As I understand it compatibility is more for the sim than hardware. Incompatibility would be from assigning them to the wrong place. Using brake instead of brake axis for example. As far as monitors the only thing Dell and I believe Asus does is buy them and rebrand them which most others do to. so, I would look for the speck you want or need and then look for the reputation of the reseller and how they stand behind them and buy from the seller who does the best job. There are only a couple of manufactures of screens so software is where one will stand out above others.
