Ooof, the other answers here make me think the answer is too many!

I have 6 consumer TVs ranging from 14" to 29", including one 28" 16:9 SD Trintron, which is a novelty for OG xbox… And 10 computer monitors from 15" to 21" (Sony G500, pride of my collection)

Majority were either free or under $10 usd, the only one I really paid through the nose for was the Sony monitor at ~$120 usd… and before the prices went mad for TVs at least in the last couple of years

However, people still sleep on PC CRT monitors, I have paid less for all of the above than some people pay for a PVM/BVM, and while none of the ones I have can natively do 240p, they can make a really good, clean emulation setup with a bit of scaling trickery and VGA conversion. Hell, one can take component or RGB directly via BNC if you can feed it a 31khz signal

I have two.

A 1981 JVC 5" radio TV, and a Sylvania 27" from like, 1998 with a builtin VHS+DVD combo unit.

None because modern CRT shaders are awesome on emulators, and real consoles are clunky and break down.

5:

1 - My main Sony Trinitron

2 - A smaller Philips vhs combo tv that I want to integrate to a retrocart setup

3 - PC monitor for my Intel 386 and AMD Athlon retro builds

4 - A cute 5-inch monochrome travel TV

5 - An Amstrad GT-64 monochrome monitor for Amstrad CPC 464, Commodore 64 and sometimes Gameboy games through the super Gameboy on SNES.

if we are counting only consumer TVs, three.

if we are counting CRTs in computer monitors and built into other devices, last time I counted I had 23.

I have a nice Magnavox 27" TV, as well as an old 17" gaming ViewSonic CRT that will do 1024x768@100hz

Got one. It works well.

I have a questionably broken PVM and that’s my only CRT TV I have. I have maybe 4 or 5 more CRT computer monitors.

I only use them when absolutely necessary. I detest CRT coil whine, and at least currently have nowhere to put them so I’d also have to dig them out to use them.

None. Got rid of my last when I got married. Owned since brand new, was a 27" Toshiba w Component and S-Video. It worked perfectly well as a kids room TV, but I also got really sick of lugging it when moving and furniture got cheaper and less stable to hold something so heavy too, so it was time to part ways!

None anymore. I’d like to get my hands on a CRT HDTV if I can find one. I saw a listing on Nextdoor a decade ago but it was old and the guy had wound up trashing it before I messaged him.

None, I’m all in on emulation and shaders now.

My last tube I got rid of around 2018. A 36" Sony Trinitron EDTV with component inputs for progressive scan. Ungodly heavy.

I currently own a 21 inch Sony TV and a 17 inch NEC VGA monitor. I’d like to get an older monitor or a smaller TV because I’m thinking about buying an MSX2 and my TV doesn’t have anything in front of it to put the MSX.

Sadly only one. Its a Commodore 1084-S D1 and it glitches out, its front cover is broken off and the power button is constantly pressed in. Its currently hooked up on my Amiga 600 while my inactive C64 sits idly around without a display.

Would it be sacrilegious to hook the Amiga 600 up to a 15 KHz LCD?

Zero. My cheap old LCD TV has a SCART and an RF in, that’s all I need!

Just one:

Commodore 1701 Monitor 13"
