@book 3 out of 4 were specifically for niche flight sim purposes...
one monitor is just a normal monitor. the other is a large-ish (24"?) 1920x1080, so low res, but this gave a competitive advantage in one multiplayer flight sim where enemy aircraft and vehicles would literally be a single pixel at most distances, and this screen has physically larger pixels...
the smaller letterbox monitor, that was when I was briefly infatuated with an Airbus simulator, and it was cheap and at 1920x515 it's just about the right size for four Airbus screens. the larger letterbox monitor is 2560x720 and just about the right size for the slightly newer and larger displays in a Challenger 650 business jet - probably the best-modelled aircraft for desktop flight sims today
and by good fortune they all happen to run simultaneously off a fairly middle-of-the-road (I think) graphics card, a GTX 3060 with three displayport and one hdmi outputs
OTOH it could be the Best Sex of both your lives.
I have THREE monitors and I know where the button* is.
* the one that turns the lights off. Oh, and the other one, 'natch.
@SwiftOnSecurity I can fix* him
