I used to have one of these (GDM-FW900) at an old job, a long time ago. They were great monitors for the time, top of the line. They weighed almost 300lbs, IIRC. And like all CRTs they can put out some heat.

LCDs at the time still left much to be desired so VFX houses weren't rushing to replace them with inferior, at the time, technology.

I remember running mine at a higher refresh rate. 75Hz and 100Hz was easily reachable. 120Hz and you started to drop resolution and the coils would sing. I miss the wide range of resolutions you could run. LCDs still haven't been able to replicate that without making everything a blurry, boxy mess.

I was able to take the broken smaller GDM-F500 (21") home. It was dim and after a bit of research I found out replacing a capacitor and a few resistors would bring it back. But it was terrifying working directly on the HV board. Once it was working I had so much screen. Almost getting electrocuted was practically it.
