 Post subject: So I found an RGB monitor on the side of the road today.

On my way home from work, I saw a pile of computer junk on the sidewalk in front of this law office near my house. I don't normally stop and dig through trash but there were several old monitors there.

Anyhow turns out I score this great Magnavox CM8762 074G. Get it home. Drop it in TATE. Hook up my Dreamcast video cable to the "CVBS in" and audio cable into the "Audio in" and it works beautifully.

So it has this TTL RGB input on the back. Can I/ How do I take advantage of it?

One guy gets a Genesis from one of his co-workers for free...another finds a good tate monitor in someone's trash...the next time one of these stories pops up I'm gonna throw a brick through a window at eBay's headquarters. ;)

I upped a picture of the rgb input. I guess I'm sort of assuming that it would be beneficial to use this, but I've no idea what kind of cables/connverters might make it possible. If anyone here could point me in the right direction...I'd be much appreciative.

Found this scripture on the net.. not good news I think.


Quote:
TV to CGA:
---------

"I have a RGB CGA monitor and would like to use it to display a composite
or S-video signal from a VCR. I was wondering if anyone knows how to
accomplish this or knows of any economical products that will be able to
do this. Any info on S-video pinouts would also be greatly appreciated."

Is it strictly CGA? If so, that is TTL and you can forget about displaying
VCR S-video without extensive and not worth-it modifications. Some CGA
monitors have composite inputs or analog RGB inputs. With analog RGB inputs,
you need an NTSC to RGB converter. These can be built with a single chip and
some discrete components. There are probably converter boxes available as
well. If it accepts composite, then just use the normal video out from
your VCR. S-video won't gain you anything unless the monitor has separate
Y and C inputs as well.



I think the input you needed on that monitor is the one to the right which is blocked by a plastic cover. There is likely nothing behind the cover though.

That's another digital-only RGB monitor. You need analog RGB to play video games on it.

It is possible to modify the monitor for analog input (I used to have such a monitor two years ago, actually). But, I can't remember exactly how I did it, and unless you're very familiar with the things I doubt you could get it to work. You'd be better off just looking for a real analog monitor.

I've found a few good-looking RGB monitors on the street, but so far none have worked :?

I appreciate the info everyone.

Guess I'll just continue using the composite input. I am really surprised how much better it look than my television, so I'm still pretty happy about it - RGB or no.

Thanks again.

Hmm, it has slight geometry issues.. thats about it. Plus I don't have enough room for a dedicated monitor that I only use once in a blue moon.

Would rather get a PC montior and XRGB2 just to save space.

I'm thinking of heading down to my local second hand store to see if I can find a RGB monitor (for use in NTSC region).

Can anybody post a pic or diagram to the type of input I should be looking for? I'm a complete RGB n00b, been using composite all my life.
