Has anyone tried this? I only to have something that works in dos, and don't really want to buy a new video card.

what exactly is it you want/already have? The way I see it, you have a standard vga card and you want to have an rca out? If so, might have solution.

Hey, someone else from Austin. I knew I wasn't alone here.

Looks like he just made his own vga -> composite adapter. Nothing wrong with that. If you got the know-how why go out and buy when you can build? Unless, of coarse the latter choice is cheaper.

BUT...Might I just add that I'm so against converting signals. If you are going to use a computer in a car, you really should use computer parts. Just like you don’t watch TV on a calculator display, you don’t want to watch VGA graphics on a standard TV monitor.

hey, I have built a comptuer to fit into my car, now the problem is, I need to somehow get the VGA signal, from the comptuer (where you'd normally connect a monitor) to a compsite singal (RCA). What would you do? I can't buy a video card, because I'm usuing a FlexATX style case, there is no room!

BTW: I tried one of those VGA cable to RCA composite for DELL laptops off ebay, those didnt work for me

Question · 04-08-2002, 06:22 AM

well at the local computer store I saw a vga to rgb cable for a few bucks...that's probably similar to the dell laptop cable you tried...anyway you could post a pic of it or model number so I could tell you if it's the same thing? I can check it easily...I go there 2 - 3 times a week...heh.

I remember back in HS my english teacher used this device that plugged into the room's PC and output to TV (via RCA cables) You need something like that. A VGA to RGB cable will not work. I still talk to that teacher. I'll email him and ask who made it. I'm sure it wasn't that much, he's cheap and so is the school...it looked like hell though. I say go VGA, spending this money on a all these coverters is BS. But if in the end you save money and don't mind the quality, or lack of more power to ya.

That VGA to RCA cable you tried was most likey made for a laptop that's video card has tv-out built in. The conversion takes place internally rather than on the cable end.

I know of those devices, the problem is they require a power supply too, so I'd have to attach that to my power inverter too

I think you're right about the cable I purcahsed, and the reason I'm sticking with composite is because my display is a motorized 6.4" LCD that uses a composite signal

I looked at other options, and this works nicely...my comptuer however doesnt like to work with it.

any other ideas?

So what?

5 volts DC at 700 milliamps. You can connect that to your computers PSU.

Here's a link to a few other of those vga - tv out devices:

Yeah, I bought that cable for 5 bucks just to see if I could help...

Sufficed to say, I'm glad the place has a 2 day return policy..heh

Ok guys...I'm gonna make someone's dream come true...I just found this Maxmedia Tv Mini by Umax...it looks like it'd cost around $170 new BUT I got it for much less than that, so make an offer.

This thing looks to be pretty cool, it's only about 4 inches by 1.5 inches...I got it brand new, as well...so EVERYTHING comes with it...Drivers (read below), tiny flathead screwdriver, manual, 5 din keyboard pass-through to power jack (read below) and ps/2 keyboard pass-through to power jack, S-Video cable,10 ft RCA cable

Output TV Video:
switchable ntsc and pal,
s-vhs, composite, and rgb videos
horizontal overscan and underscan
vertical and horizontal position shifted
(S-VHS TV Video out, RCA out, Mini Din 9-pin female RGB TV out)

Front Panel Control with
adjustable tv brightness
adjustable tv color phase
horizontal and vertical position control

Driver:
No drivers required for NTSC under VGA 640x480 60 Hz graphic mode
Supports resolutions up to 800 x 600 (PAL) and 640 x 480 (NTSC) true colors
-Vertical and horizontal position control utilities for Windows and Dos

Power (one of the coolest parts)
Powered by the keyboard port! (5v)

Input:
VGA video input

Like I said, I got a spectacular deal for this, so whoever wants it, email me with any offer at f*c*c@mail.utexas.edu (remove the *'s...spam protection) and I'll give it to the highest bidder or person who convinces me they need it most.

here's some pics:

sorry bout the quality, my digital cam sucks

I can't believe nobody's said it, so I will: These devices are called Scan Converters, are nothing new, and are pretty ubiquitous. Chances are your school owns a few. A search on eBay turns up plenty. If you've got the money (expect to pay $75-200 for one on eBay), your problems are solved.

Question · 04-14-2002, 01:02 PM

And my point is that I'm willing to sell it for much less than that and that this is another solution available to those who need an external solution for VGA to NTSC. Please read the entire post before commenting.
