Hey everyone!

I'm interested in buying a monitor that can sync down to 15kHz (supporting digital TTL video) and also support SVGA. I don't really care about brands or models, so long as it's in good condition and still has a sharp picture with little to no geometric distortion. If anyone has one close enough for me to pick it up, that's what I'd prefer, but I'm willing to pay shipping provided the monitor cost isn't all that high. Let me know what you have, and please send pictures if you have them!
 
I have a NEC Multisync JC-1401P3A in excellent condition. This model is the original NEC Multisync.

Here's some excerpts from the spec sheet:

Synchronization RangeHorizontal: 15.5 kHz to 35 kHz
Vertical : 50 Hz to 62Hz

PC Compatibility
640 x 480: 56 to 62 Hz vertical refresh
800 x 560: 56 Hz vertical refresh


It's in excellent condition.

It's a beast, ~ 40 lbs. when packed, so just the shipping would be roughly $80 - $90.

It's the only monitor I use on my bench.

That's really close to what I'm looking for, although 800x560 is a weird top resolution (I was kind of hoping for 800x600 since that's the top resolution of the graphics card on the machine I intend to hook it to). But that shipping is killer! I could pull it off, but I'd have to offer you next to nothing for the monitor itself.
 
i have a JC-1401P3A in not so good condition (yellow, little fuzzy, green tint on everything) I got it to do 800x600 @56hz but it complained loudly about it
 
The NEC Multisync 2 will also do that and it is better because the picture doesn't lurch sideways after a format change. Even better is the Sony 1402.
 
I'll still stick by an early Mitsubishi Diamondscan, if you can find one. Does pretty much everything: MDA/CGA/EGA/VGA as well as composite TV-type video.

If you're interested in LCDs, there are some NEC Multisync LCDs that will do that--check specs, though.

An LCD would be fantastic, actually (takes away a lot of the geometric distortion issues I get worried about with CRTs, even if it is a trade-off for contrast and/or motion blur), but I'm having trouble finding any that are verified to work down to 15kHz. And I'd also probably want one that's 1280x960 or better (1280x1024 was common, wasn't it?) so I could use even pixel doubling for 640x480 screens.

My Mitsubishi AUM-1381 Diamond Scan monitor is also rated at a max resolution of 800x560, but it works perfectly fine at 800x600, and even at 1024x768 interlaced (if you can stand the flicker).

Here's a cheap Tandy CGA monitor:

I have a mitubushi e85 LCD, which is just a 18 inch NEC in a black case, and while it will support a lot of screwball signals, and I bought it brand new in year 2000, it wont accept 15khz or TTL level signals

and yea its 1280x1024

the JC-1401P3A might do 800x600 mine just needs some TLC, always has ever since I bought it, back when my 386SX with EGA graphics was a boss machine so a nice one may not have issues ... mine displayed just fine but there was quite a wine coming out of it lol

what about one of those fairly inexpensive CGA blah blah blah to VGA arcade converter boards, 30-40 bucks use whatever monitor you want, and I hear they are pretty decent

look it up on fleabay or amazon, for example

The screen that can display absolutely everything seems to be a bit of a unicorn.
Personally I'd go with an early multi-sync for MDA/CGA/EGA, and just keep a $5 LCD on the wall for VGA/SVGA.

What I'd really love to see is a quality MDA/CGA/EGA to VGA converter for a reasonable price.

I'm amazed you have any left, these are fantastic monitors for PC collectors.

Yes, they're fantastic and they do VGA quite well, too! :)

After doing some searching, I saw that this monitor will apparently sync to an Atari ST even though it isn't officially specified to do so, so I just bought one and we'll see how it goes.

Keep in mind that the Atari ST (as well as the Amiga and Apple IIGS) puts out analog RGB video, whereas CGA puts out digital RGBI video. Using CGA with a 15 kHz-analog-RGB-capable monitor will require some custom circuitry to convert the signal type.

Yeah, I'm aware of that. I actually wrote some PAL equations not too long ago that convert a 4-bit RGBI signal into a 6-bit digital RGB signal suitable for feeding into an R2R array as a DAC, so that won't be too difficult for me to set up.

or you could just get the already made adapter that works fine ...

And suck all the fun out of it?

If you mean one of those GBS converter boards, I've had one for a couple of years now and it's kind of a piece of crap.
 
There used to be hardware that could adapt CGA signals to a VGA monitor.

Those of us with Amigas do this all the time. I've always found this a much better solution than a monitor that can sync that far.

Okayyyy you guys are already discussing this. Somehow i didn't get the last five posts till now.
 
Some of the NEC monitors are very flexible (i.e. the ones with 5 BNC connectors). They'll do RGB SOG, RGBS, RGBHV. Perhaps not RGBI, but that's simple to accommodate.
