This is the smallest commercially made CRT monitor in the world, used in the viewfinder of a mid-90s Sony camcorder. The model number of the CRT is "MIYOTA 1-452-673-31". The screen size is approximately 10mm x 7mm. The length of the tube is about 5cm.

To use the monitor with my Raspberry Pi 3B, I installed the latest version of 64-bit Raspberry Pi OS and in the file "/boot/config.txt" I added the line "enable_tvout=1". The first Raspberry Pi model used to have a dedicated composite video port. With the newer Raspberry Pi models, the old composite video port is not gone, but has been moved into the 4-pin headphone jack. So any Raspberry Pi can still drive a CRT monitor without issues.
