Yeah this is a big change recently: on AlixExpress you can find genuine =
round and square LCDs with HDMI or similar interfaces for decent prices. =
This would make creating eg a real ISFD:

(sorry for the long link)

Annoyingly what still seems to be unavailable is a square LCD =
corresponding to the old square displays used in the 747-400/7373NG/777 =
era cockpits: thus would be something like an 8=E2=80=9D =E2=80=98square=E2=
=80=99 LCD and the largest truly square displays seem to max out at 4=E2=80=
=9D like the one above.

Kind regards,
James
