Can this 20" 15KHz Mitsubishi monitor be used for my setup?

[DeLuSioNal29]

Hi Folks!

I recently came across two 20" Mitsubishi Diamond Scan 20M (model HC3925KTK) for free.    However, after hooking them up to my standard VGA port using the cable (5 BNC to VGA cable).  The monitor would not show an image.

I had assumed that the monitor was standard.  However, I did some more research and it looks like it is a 15KHz monitor with a maximum resolution of 800 x 600.  It came from an Avid editing system, so is specialized.

Here are the specs on the monitor: 
http://www.monitorworld.com/Monitors/mitsubishi/diamondscan20mhc3925atk.html

So here are my questions:
1)  Since it's 15KHz, would I be able to pop an AVGA2 card in there and see something on the display?
2)  There are 2 VGA ports on the monitor and 5 BNC connectors.  Which one should I use to connect it to my PC?
3)  If I were to use the BNC connection method.  What goes where?  There are 5 inputs.  (see attached pic).

** edit **  I found this guide on how to connect here but I am still unsure of what to do:  http://www.monitorworld.com/Cables/hd15male_to_5bncmale.html

Thanks in advance for your help!

I am pretty confident that:

1) Yes, would connect fine to the AVGA
2) Use the VGA port (Signal A)
3) The colours match up to the back of the monitor ports exactly in the order you have them in the cable pic, starting from the top down corresponding to left to right on the monitor. However, you should be fine with just VGA.

I have this exact model of monitor and it works beautifully with MAME and 15khz resolutions.

You can search my posts here for more information.  I've posted about it in several different places.

A few notes:

You need to use the Signal 3 option on the switch on the front of the monitor to display an image from the BNC ports on Signal B.

I've never been able to use the VGA input.  I'm not sure it is for what we think it is.  It might be a VGA out for all I know.

You will also need to adjust the luminence controls in the back.  I can't remember whether you use the High setting or the 75 ohms setting, but if your image looks dark then change the setting.

The maximum resolution for this monitor is indeed 800x600 so you will need to have a low resolution set before you try this monitor, or you can start windows in VGA mode.

Don't give up on this monitor.  You basically got a 19" Digital Multisync arcade monitor for free.

So this monitor requires an AVGA card?  I was hoping I can get away with using a soft 15KHz hacked ATI card.  I tried it in my current setup (I have a Betson and and ATI HD with soft KHz installed) and I could not get anything to display in the monitor.

Thoughts?

It's possible your graphics card doesn't work with that computer.  For some reason when I first got my monitor it didn't want to work with the computer I had set up for it.  I have no clue why this happened, but I hooked up another PC and everything worked perfect.  That motherboard still doesn't work on the monitor.

You don't need an ArcadeVGA.  I use Nvidia cards.  I have a Geforce 3 and a 6800 and both work well with advancemame and soft 15khz.

I use Nvidia cards.  I have...a 6800 and both work well with advancemame and soft 15khz.

HOW did you get your 6800 to work with AdvanceMAME??

[Jack Burton]

My mistake, I was mixing up video cards I own. 

The cards I use with advancemame and soft 15khz are my Geforce 3 and a 5200 FX.

I have  a  6800.  It seems to work fine with soft 15khz but has troubles with advancemame.  I'm not sure what the deal is. 

[DeLuSioNal29]

Thanks for the reply.  I'll have to give it a shot.  So far I could not get it to work.  I'm suspecting it's a bad BNC cable.  One of the connectors is frayed.

I'll order a new one and revisit.

Thanks again.

If you can get pictures Delusional, always like seeing the unique look different monitors bring to the classics.

AHHHH, ya freakin hooligan, ya got me all excited.

The specs show it as 15-38Khz on the page you found.   You should be able to display both MAME and Windows up to 800x600.   I would try setting your windows to 800x600 or lower and at 60hz before connecting it.  A standard card will work for that, but using ArcadeVGA or Soft15Khz will get you the arcade resolutions.

Hey is this a Arcade monitor or a PC monitor. Did you get it working yet. Any pics of the screen woith classis on it

I'm interested in how these specs compare to a typical arcade monitor.

[mytymaus007]

Looks like a PC monitor! Are these specs close to an arcade monitor I need one of these for my desktop!

[Jack Burton]

The 15-38hz scan rate means that it supports the native resolutions of arcade games, and you could even connect an actual game PCB to it if you wanted to.

When I first got my MK cab the monitor in it was broken and I used this one for a while.

The other specs say that this monitor is of a higher quality than most arcade monitors, and the dot pitch means that the image will be much sharper than a typical arcade monitor.  This is either a good or bad thing depending on what type of games you want to play.

[mytymaus007]

So if i dont have a cab an want to get a monitor for my desktop would this be the best bet or can i get a tv that would be better. I would love to have an arcade monitor but there is no case on so i can use it on my desktop. iI want to play the classics

[Jack Burton]

It would make a decent desktop monitor, but you would have to live with 800x600 for your resolution.  This is livable if you mostly just want to use your desktop for gaming, but is unsuitable for daily computing. 

If you used this monitor for your desktop I would combine it with a typical PC monitor and go for a dual display setup, using the regular PC monitor for internet and other pc functions, and leave the Mitsubishi for MAME and older console emulators.  I do this a Sony PVM 12" monitor and a monitor switch and it works very well.

[mytymaus007]

i actually just use my pc for MAME anyway but is this monitor as close as im going to get to an arcade monitor or is a TV better.

[Jack Burton]

It's miles better than a TV.

For all intents and purposes it IS an arcade monitor.  It just happens to have  plastic casing around it.

[mytymaus007]

thats what i was looking for Awsome!! is there any other monitors like this one with the casing around it.

[EvilDindon]

This multi-sync monitor is just perfect for a mamecab prject.

It has similar specs than WG D9200.

[Ummon]

This is the same as those 19" multisyncs. It's just in a PC monitor housing. If you can find one, major bonus for those who don't want to large, but want all the benies of a multisync.


DeL:

a) need some close-ups of the screen to see the pretty lines.

b) when switching above SVGA, Windows might be setting the refresh above 60hz.

Update to an old post:  It was indeed a bad BNC cable.  I order a new one and it worked like a champ!

[markoshugogc]

hi there! i recently got 2 of this babys, i want to see your profile to dig more info about them but access is denied. can u send me some picture how the look with mame in 15khz?
