I found a cctv monitor at a thiftstore and am wondering if these are any good for retro gaming. I couldn't find the exact specs for it, it seems to be an intermediate model (at best it'll be 720 lines), it's a 14" colour monitor with controls on the front (hue, saturation, contrast & volume). The I/O is a bit disappointing though. It only has a BNC in and another BNC out (both females iirc?), two RCA audio IN and a unique RCA audio out. I couldn't test try it out properly but while powering on/off there were no noticeable screen burn and it showed a solid blueish color. I liked how compact it is and how it could possibly fit for some of my consoles. I know I need some RF Banana adapters but will I need a signal converter too? My doubt is I don't know what type of video signal it accepts or if I'll have audio through BNC. Since it apparently lacks a tunner, how could I connect my systems with the RF Banana cables I have for those?
As I work on cctv, your changes of it being a good monitor for gaming arent high. Most of these monitors are meant to just get a picture out to you, not always to show a quality picture since they are just meant for review. Some can be very good though. Im a little surprised there is no burn in though. if the price is right its worth a shot. Audio wont go through bnc as there is a breakout adapter for audio. You wont get RF into it.
What type of video signal do you think it accepts, given the only two bnc connectors? I can only think of composite.
Also some CCTV are just mono. It might be fine if you're programming 2600 game and wanted a legacy B&W switch to work as intended but B&W display for gaming have been not worthwhile for over 30 years.
I'd never trust an old CCTV monitor. Apart from the fact it's not RGB, it's going to have been thrashed 24/7 and you simply don't know when it'll die. Leave it where it is.
