Okay, not exactly a TV but worth a mention. I got this at a computer shop for 10 bucks. I have been wanting something like this for a retro-look PC build, and who knows what else it would be handy for with that jack pack.

I already had a NOS early ATX tower case, so this might get the Retrobright treatment.

Hope it doesn't have a whole lot of hours on the CRT. Otherwise nice find!

I mention that because every big monitor I found before LCD's replaced CRT's was used until the CRT got too weak to get a decent image, and the date on yours is 1996 so that thing probably saw use almost every day from 1997-2003 ish

Awesome! I picked up, nearly that same model some years ago. I used to play Sega Genesis and SNES with RGB, it has a great picture.

It seems to have plenty of life left. :) I'm using it for writing this post. Even at its lowest brightness setting it shows an image.

I wonder what that molex-type connector on the back is for?

The first high definition big screens had that type of plug ins, if you could find the hdtv box from the late 90's to early 2000's you could use it as a high def tv. The first hdtv's had to have the vertical and horizontal sync with the rgb. I need one with vga output for my zenith.

He means the recessed connector on the left, not the VGA socket on the right.

You can use any modern HD source with a computer monitor if you buy an inexpensive HDMI to VGA converter box. There are tons of them on ebay for around $10.

1080i requires the same horizontal scanning frequency that 540p would, and since virtually all computer monitors support at least 800x600, 1080i will be no trouble. 1080p will be doable by most 21" monitors since it's less demanding than 1600x1200 at 60 Hz. Just reduce the vertical size for 16:9.

Sweet! That thing brings back memories of playing Doom and Starcraft on my old family computer! I should never have dump my old CRT monitor...well at least keep one for retrogaming because its not as fun to play Diablo 2 in 4:3 on a 16:9 LCD monitor.

By the way, how would I use it with the BNC connectors? I have no idea what those marked H+V/H and V are for, or if it can be used with just the RGB connectors or what.

The H and V are for horizontal and vertical sync

and no you can't use just the RGB connections. You need an RGB source with seperate horizontal and vertical sync. Or RGB with H and V on a separate line as that's likely what the "H+V" connector is for.
