I agree with the OP. Airbus hit a home run back in the 80’s with the displays, but they haven’t really improved on them much since then.
Compare the original 757/767 screens that were developed around the same time to what’s in the 787 and 737 max now, and you’ll see what I mean.
I even prefer the displays on the 737/777 from the 90’s to the displays on our newest NEO’s.
Airbus leapfrogged Boeing’s 757/767 EFIS, and Boeing improved on the A320 display in the 90’s and again in the 2000’s.
I wouldn’t want a direct copy and paste of the Boeing displays though, because I do find them a bit cluttered (example: why’s the FD displayed on the ground?)
I’m not asking for the expansive display suite that the A350 has, but a facelift would be nice.
