anyone in the Tuscaloosa/Birmingham AL area looking for a decent quality CRT by any chance? Goodwill won't take CRTs and it's a shame to let them go to the dumpster since no one makes them anymore

Might as well ask here before going to craigslist, but I don't think we've seen a single other person on here from around here in the first place so.... not really expecting any answers

if you *are* interested, it's a security monitor that was never on the consumer market so there isn't a ton of information out there for it, but it's a large screen (about 26"? can't measure now so that's an estimate), and has two S-video inputs as well as two RF inputs (BNC connector as common in security systems, instead of the F connector common for TVs). Mono speaker. Good for video games from the 90s to mid-00s; S-video is the best quality you'll get out of an unmodded SNES for example

@Felthry what kind of crt is it, and how far are you willing to travel to meet for it?

@trwnh How far? I dunno, really. Could probably go to birmingham or something

As for the type of CRT I posted out it in a follow-up just now, can get more details if you want (it''s out in the car right now)

@trwnh We have no idea what it's worth, were probably only going to ask like $10 for it on craigslist if we went that route

I should note, while it turns on, we do not know whether it actually works. we don't have anything to give it a signal; don't have anything that outputs s-video (or at least don't have cables for it)

@trwnh Yeah but I forget what it was, give me a minute to go out to the car and check--i'll measure the screen size too

@trwnh it's a panasonic CT-2010Y, and it's a 21" screen so I had overestimated the size

@Felthry ah okay, that's far more manageable. let me look at any specs that i can find, and maybe we can coordinate a meeting time and place?

@Felthry hmm, doesn't seem terrible, but maybe not so great either: broadcaststore.com/store/prod_

450 horizontal lines is not very high but should be roughly enough to not be fuzzy -- pic 1 attached is 250 TVL vs 450 TVL. pic 2 is 350 vs 600 vs 800.

@trwnh I'll be honest, we don't know a ton about this stuff; I thought the number of horizontal lines was fixed by the NTSC standard?

@Felthry resolution of the input signal and the output on the display are not the same, afaik

@Felthry @trwnh it is standardized but there's always less because overscan

@Felthry @trwnh also you can just draw more lines with the same info I guess

@trwnh oh hold on I see it; it's the *horizontal resolution*, aka the number of vertical lines; the number of horizontal lines is the vertical resolution and is relatively fixed

@Felthry @trwnh technically the horizontal resolution is infinity, at least in luminance
or are we talking about the lines of colored phosphor?

@noiob @trwnh Horizontal resolution is technically infinite in a black-and-white CRT, but not in a color one

@Felthry @trwnh that's why I said luminance, as color tv is backwards compatible with b/w tv

@noiob @trwnh that's still not actually quite right since color CRTs are built differently than black-and-white ones; they don't have continuous phosphor over the whole surface

the backwards compatibility is by lighting all three of the phosphors at once, just like how an lcd panel illuminates all three subpixels at once to do greys and whites

@Felthry @trwnh a dot of phosphor is still not one pixel, it'll still light them up just like it would on a b/w tube, you'll just have the colored stripes over the image
