I just got done setting up my second Nieman monitor and thought I'd post up some information on this new monitor.
Nieman 24.8 Multisync monitor, model # 3M25CH666
Noteworthy specs:
Horizontal sync - 15k, 24k and 31k (automatic) (cga, ega or vga)
Video input signal - 2.5v - 5.0v TTL OR 0.7v analog
Sync signal - seperate or composite
Connections - 15 pin D-sub with 6 pin adapter for wiring to existing Jamma harness
CRT - Flat screen CRT
Power - 100 to 240vac, no isolation required
Resolution - 560x240, 640x350 and 640x480
Adjustments - There is no on-screen menu (this isn't a digital monitor), but in addition to the usual adjustments there are pots for: pincushion, rotation, sub-contrast, trapezoid, sub V height and more. Really all the adjustments you would ever need to make (other than convergance) are provided for. Common adjustment pots are on a remote board.
This is the second one I've gotten from Amusements Plus. It got installed in a generic cab with a Carnival King Shooter kit. Out of the box this monitor has a great picture. Running in vga mode with the Carnival King kit the picture is very sharp with no convergance issues. Geometry was off some, but quickly corrected with the ample adjustments this monitor provides. Color and brightness is uniform across the screen and the light gun registers perfectly all the way to the extreme corners of the tube (something that can be tough to get on other monitors). Overall I am very pleased with this one, the picture has great color and excellent contrast and sharpness and works great with the light gun without having to be even the slightest bit over-bright.
The first Nieman monitor I got went into an Cruisin' USA and right back out on location so I didn't get the chance to play with it at all, but that one had very minor convergance issues, mostly at the extreme edges. Besides that, it too had excellent color and contrast and good sharpness, even at the medium res that Cruisin' runs at.
I have yet to try one of these at standard res.
First impressions of the chassis - All thru the hole components, no surface mount. Chassis is not too crowded, so servicing should be typical. Solder joints and assembly look to be good, no indications of cheap assembly.
I haven't had them in service too long, so I can't report any long term. But so far they are looking good and I intend on using them again next time I need a 25".

This is good news. Sounds like a good monitor and I like the fact that it's NOT digital. That's a big step up in terms of reliability and ease of repair.
Here's something you can do right now before you put the next one out on location somewhere. For future repairs or chassis swaps how about providing us with the following information too:
Yoke resistance and if it uses the usual red & blue wires for horizontal and green & yellow wires for vertical.
Yoke part numbers.
Flyback part numbers.
What adjustments are located on the remote board and what adjustments are on the main board and neckboard.
Does this monitor accept only composite negative sync or can it also accept positive sync?
Did it come with a manual and schematics?
Is there a website for the manufacturer?
-
Next one I get I'll try to get yoke information and part numbers.
Remote board adjustments are:
Bright, Contrast, V Pos, V Size, V Hold, H Hold, H Pos, P Cush, H Size
Chassis adjustments are:
Rotation, V Size 2, Sub Contrast, Trapezoid, V Line, 31k Freq, B+
Neckboard:
Red gain, Blue Gain and the three cutoff's
The documentation states it will accept seperate OR composite sync, positive OR negative. I didn't have the luxury this time of trying different sync's to see how it handles them.
It did not come with a manual or schem, only a single sheet with basic hookup information, specs and adjustment pot layouts.
Nieman's website appears to be mostly under construction. It looks like there will be a support page with schematic downloads, but for now it appears that they are handled on a request basis. I'll probably request a schem for the monitors I got so I can see how well they respond. The sheet that came with the monitor claims that if you register the warranty they will send a complete manual
Niemans web site is: niemandisplays.com

I see they are located in Canada.
I noticed on their website they make universal replacement chassis. :applaud:
This is getting interesting. I'd like to know how long it takes you to get a schematic and if that schematic is clear and readable.
Looks like this newcomer to the arcade monitor business might be ok.
-
Fine company. Good to deal with and has extensive technical knowledge.
-
How come nobody has ever heard of this (Niemen) company unitl just a few months ago?
-
25" multisyncs appear to be fairly rare, does anyone even know of a competitor to this? I can't recall seeing one myself. I could actually really use a 25" multisync monitor for my new cab project.
-
How much did you pay for the monitor?
-
I don't know, the op/owner pays the bills !!! All I ever see is the shipping invoices... ;D

Rick - Just FYI I e-mailed the guys in Utah who are supposed to distribute for you (forgetting the name off the top of my head) and never heard back from them. No worries for me personally, I'm on hold until I finish my fiscal year for purchases, but you might want to check with them if that's an issue for you. I'm still hoping you find someone to distribute in LA before I drop the $ on shipping. ;)

How does this compare to the Billabs BL27CB0P? I will be putting it in my cocktail table.

Hey all, i'm considering getting one of these monitors but I want to hook it up to a PC. I guess I'd need an arcadeVGA. Anyways, I'm confused about a few things. How do these specs:
Horizontal sync - 15k, 24k and 31k (automatic) (cga, ega or vga)
Resolution - 560x240, 640x350 and 640x480
Compare to these specs from the FAQ:
What is the resolution of my monitor?
Monitors are classified by their horizontal bandwidth and number of visible lines. This effectively describes their resolution. You can roughly estimate their vertical refresh rate (frames per second) by dividing the horizontal bandwidth by the number of visible lines. For a standard resolution monitor this would be 15750 / 240 =~ 65 Hz.
resolution horizontal bandwidth # lines # colors comparable
standard 15.75 kHz 240 unlimited CGA or NTSC TV
extended 16.5 kHz 288 unlimited CGA or PAL TV
medium 25 kHz 380 unlimited EGA
high 31.5 kHz 450 unlimited VGA
Will this monitor be able to support all the MAME Games?
-
Yes, this will support pretty much all MAME games. The truth is anything that runs at this monitor's high res setting probably isn't even emulated well enough to be playable, almost everything is going to be standard res. More likely than not the 640x480 picture will only be used for your front end.
-
There are actually quite a few older games that want 480 horizontal lines (512x480, 480x480). Spy Hunter, Arch Rivals, Discs of Tron, Tapper, Two Tigers, Wacko, Xenophobe, Rampage, Pigskin and others. Of course, Tron/Satan's Hallow are 480 lines but mounted vertically (480x512). These particular games look just fine on a standard arcade monitor running 640x480 interlaced though.

Ok Guys, I am very anxious to know more about the mame application..
I am still trying to find time to do the testing myself, but am not there yet...
This offer is not meant to short circuit my distributors but is meant to help us all.
If you want one of the 24.8" Tri Res, normal retail pricing by my distributors is $485 plus freight.
I will try my best to get the monitor to you at the $485(USD) including freight, worst case a $50 add on, but I want feedback.
This offer is time limited and requires payment by credit card, money order..
It is also not available if you are in a State where we have a distributor, sorry but I value my distributors, my customers and my friends.
Good feedback is nice, but problems are only opportunities to get better.
Contact me by e-mail if you are interested and serious (keep in mind serious as every once and a while I try to find time to sleep)
Thanks again

Rick,
For Info about MAME, try:
www.mame.net
www.mameworld.net
www.mamedev.com
www.retrogames.com
The hard part for MAME is getting ROM files. You either need to dump them from authentic arcade boards, download a few sets from MAMEdev.org, buy a Capcom Coin-op Classics CD from HanaHo Games (www.hanaho.com), license them from a game company, or get them from ROM sites (Violates Copyright Law). I wish more game companies would legitmately license them for MAME. I know Atari did a while ago (through the Defunct StarRoms), Capcom Did (Through HanaHo Games), and several other smaller people made a few ROMs as Freeware (Jamie Fenton, Howard Delman, Duncan Brown, Exidy, etc).
-
FYI - I have my Nieman monitor now, but it's not in my cab yet and I'm still testing some stuff out, so I won't give a proper review until I've got things running how I want. Rick is super responsive as always to my questions and Larry in AZ who I bought it through was awesome. :)
-
this monitor will plug right into a vga video card right?
-
Yes the monitor is fitted with a standard 15 pin sub-d cable that will plug in, it also comes with an adapter and instructions to connect it to a 5 or 6 wire connection such as Jamma.
Hope this helps...

Just a shameless plug for Rick but as you can see, Customer Service is a top priority for him!
I've met Rick and his crew and they are a great bunch of guys. I suspect that he loves his work so much that he "never has to work a day in his life."
Try getting good tech support (or products) from WG... need I say more?
Again, this is a "good guy" plug for Rick and his products (and his support!)
Davester.

I see this thread has jumped back to the top so I thought I'd use this to update:
I now have 5 Nieman monitors out on location, 24.8's and 27's in a variety of shooters and driver games.
The monitors have been working great, no failures of any kind.
I'd like to vouch for Rick's tech support, but I haven't needed it! (that's a good thing!)

if you ever decide to ship to auz, let us know on aussiearcade.com.au,
i'm sure a few peeps will club together for some monitors
-
I have actualy been in touch with Joey, the thing that kills us is freight.
A skid of monitors is 12 or 16 pcs, freight is about $100 each. So to sell to a distributor there who needs to make some $$ is almost impossible.
Anyway, rough guess ig you get a bunch of buddies together to take 12, somewhere between $515 to $585 landed.
Thx for the interest.
Rick

If I was an aussie, I'd go for that. I can imagine how scarce new, or even used, arcade monitors are down there. Buy the 12, and I bet you could sell them for 100% profit.
