Possible RGB Monitors?

[Tempest_2084]

My lab at work is throwing out two 20" flat panel displays that I think are RGB monitors. They have RGB BNC connectors in the back, and one even has a VGA port. The model numbers are:

Modicon MM-FMP9-100
Intecolor E20FPA-200

I can't seem to find much information on them. All I know is that they're industrial touch screen displays for PLC's. Anyone know anything about these?

Another question: Assuming that one of these monitors is a decent RGB monitor, is it possible to use Composite or S-Video systems on an RGB monitor? I don't mean convert the signals to RGB quality, but just somehow plug a composite or S-Video system into the RGB plugs in the back? Something tells me that no, you can't, but I I didn't know if there was possibly a converter of some type that could do this.

These are low-end LCDs from the mid to late 90s. Nothing you want or need even remotely interesting.

All I know for sure is that while PAL TVs receive RGB via SCART, plain composite can be also fed through SCART socket. Never heard of S-Video signal being applicable to SCART, so my guess would be other RGB sockets won't take it either.

At the end of the day, low (sub-native) resolutions will not look good on LCDs no matter which colour system.

standard in Europe. All mid-class+ TVs in the 90s were equipped with two Scart sockets. First one took composite and RGB, second one composite and s-video. S-video through scart uses the composite video pin for luma and the red pin for chroma.

Are you sure they're LCDs? They look like CRTs to me. They're about as big as my PVM and one is a curved tube and one is flat panel.

The Intecolor E20FPA-200 certainly is a LCD. I couldn't find any info on the other one.

So last century. SCART is (or was until very lately) still pretty standard even in PAL-region HDTVs, but only one per unit (and I think only RGB/composite comes through it). Didn't know the second SCART I see every now and then in older TVs was for S-video.

I think there's bad info or something on the web as these are both definitely CRTs. I think I'm going to snag them and try them out at home to check out the quality. I figure if I don't need them someone else might want to take them off my hands at Vintage Computer Fest.

[Tempest_2084]

Yep they're CRT's, I just cracked open the cases to take a look. I hope these work with my home setup as they look so minty I doubt they were used much (we're a small test lab so they probably sat in a back room for years without being turned on). The one also has a VGA port so I guess I can use my DC VGA box with it as well.

I see the ebay auction for the Intecolor E20FPA-200. That screen looks exactly like the one I have except mine is a CRT. I wonder if they updated the model without changing the number?

Dumb question: If these monitors also have VGA ports on them, does that almost 100% guarantee that they're 31KHz RGB rather than 15KHz or is it possible it does both? These are industrial monitors for PLC's so I'm not sure if there would be a reason that they'd go down to 15KHz.

[Fudoh]

does that almost 100% guarantee that they're 31KHz RGB

yes.

15khz is extremely unlikely.

That's what I figured. I don't think it's worth the hassle dragging these things home to test.

Might be easier to bring a 15 KHz signal to work. Though that might be frowned upon, depending on your work environment.

I'd take the chance. But that's just me.

[Tempest_2084]

I guess I could, but I really don't see why an industrial PLC monitor that was hooked into what is basically a 386 would do 15KHz RGB. There are a few monitors here in the lab that have RGB inputs, but they're all 31KHz (I've looked up the specs). I doubt these would be different, but I guess you never know.

I might just do that. I'm here late a lot so no one would care. The only problem is that I'd have to unhook my sync strike and a game system and hull those into work.
