A Sony Trinitron CVM-1270 is available here. I haven't found specs
for it but the manual for the PVM-1353MD and PVM-1953MD is at
https://docs.sony.com/release//PVM1353MD.PDF. On page 13 "Color system
NTSC, PAL". Haven't found anything about switching. Appears these
monitors recognize NTSC and PAL and switch automatically.

We are presently using a 30" Sony that switches between NTSC, PAL, SECAM, et.al. as needed. So, this does not surprise me. Also between 100, 120, 220 & 240, 50/60 HZ.
