This old lady is the monitor of my Pentium 3 retro daily driver!
It's a Crystal CM-1402E made in 1989 by Intra Electronics, 14" shadow mask monitor with a .31mm dot pitch. It was made under several brands such as Arcus, ARX, Ancer, MGC, Crystal, Intra, Socos, JET and many others. It's one of the earliest "8514/A compatible" VGA monitors and supports only three resolutions (640x480, 800x600 and 1024x768 interlaced) along with a few sub-resolutions. It's not a real multiscan monitor and makes it akin to an IBM 8514 in terms of features. Picture is kind of fuzzy but it's not blurry and unreadable: the "fuzziness" of the screen smooths out fonts and graphics giving to the overall appearance a very pleasant look and doesn't make 640x480 look huge. It's also not a quite flickery monitor despite I run it at 60Hz. What I love most of this monitor is its colours, as they are very deep and vibrant, something I could only dream of on a flatscreen display.
I had some niggles with it the first time I got it: red tended to flicker and disappear randomly until it finally stopped flickering for good, for a period it jittered when being turned on at cold (fixed the issue by using a non grounded power cord, I suspect it was a ground loop issue) and its connector is quite mangled since it was a bit mistreated after two decades of storage.
Thankfully all these issues have been fixed but in future it definitely needs a capacitor replacement to make it work as good as it was back when new. I love this monitor to bits.
