A couple of times a year I’m using an old Olivetti CRT - green monochrome with VGA input - on an old DOS machine (upgraded to IBM PC-DOS 5.0) I inherited from work more than 15 years ago.
It still shows a shadow image of the command interface for the online (pre-internet) database it was connected to 8 hours a day for ca. 10 years before I got it.
But it’s still fine for checking incoming diskettes (3,5 inch hard-shell diskettes, as the windows save-icon - NOT floppy as the 5,25 inch floppy-disks on the machine that predated it) before backing up the data.
Samo on older CNC machines in our mechanical shop. Some very large horizontal lathes (we make and repair rolling mill gear on them) are relatively old but work really well. They still have Fanuc and Sinumerik control modules with CRT on them. And yes burn in is there , and very strong. Last time when CRT died , repair Maister just replaced it with generic 12" industrial LCD.
