3. 60hz CRT refresh rate is 16.67 millseconds of delay. Interestingly, I connected a VT220 to my 56' 4k Samsung TV via a BNC-to-RCA cable, and by comparing the cursor blinking on both screens there's a very noticeable and visible delay, like a 1/4 second.

4. CRTs are analog. It's as many bits as your output hardware can make up.

5. CRT is still supreme for contrast (at least over LCD) despite all the tricks and such for LCDs.

7. That VT220 I mentioned above is from 1986. It's monochrome, but works great.

Actually the horizontal resolution of a CRT is limited by: the dot pitch of the colour phosphors, the bandwidth of the amplifiers, and the electron beam spread.

The vertical resolution is limited by a combination of: electron beam scan rate, delay for horizontal flyback/retrace, delay for vertical flyback, desired refresh rate, and electron beam spread.

There are more details for the resolution limitations, but I think I covered the main ones.
