#Nec 3D questions
31 messages in this thread
I just recently bought a NEC 3D monitor at a garage sale (Nice Monitor!)
Unfortunately, no docs came with it. 🙁
So, could someone answer a couple of questions for me?
What is the Mode button for?
Is therer a way to store preset screen postions, (so I can center
Super72 and the other modes)?
Is there anything else I might want to know? 😉
Any help would be apprectiated!

I've got the 3D docs. To be honest though I don't completely understand
the documentation of the MODE switch so here is the direct quote. The
MODE switch "selects the monochrome mode or color mode with a TTL video
signal input. With an Analog video signal input and the MODE SWITCH ON,
the monitor will give the user an additional user programmable memory
area." The following table is then given.
.MODE Input Video MODE
.SWITCH Signal
.—— ———– ———————————–
.OFF TTL General Color Mode (CGA,EGA)
.OFF ANALOG General Analog Mode )VGA, PGC, etc)
.ON TTL Monochrome Mode (MDA)
.ON ANALOG User Programmable Memory Area
If you can make heads-or-tails of all this let me know. All I know is
that my system (Flicker Free Video II on Amiga side and VGA on Bridgeboard
side) seems to work better with MODE switch off
I don't see anything in the docs about storing preset screen positions
(except I believe it does store the current settings). But again the
extent of my understanding is mostly "plug it in and fiddle with it until
it works."
Thanks! That's the info I need!

Considering how much I had to pay for my NEC 3D a few years ago, I don't
want to know how much you paid for it at a garage sale <g>. Quoting from
the manual the revalent info: "Mode switch – With an Analog video signal
input and MODE SWITCH ON, the monitor will give the user an additional
user programmable memory area." Basically what it's telling you is that
the 3D 'remembers' screen settings based on what kind of signal input you
are using. So having the mode switch on gives you more memory for those
settings. BTW, the AUTO switch does nothing in Analog mode, it's only used
in the TTL mode. The NEC 3D is not a bad monitor, but it does have it's
quirks. I have 1" black borders on the left and right of the monitor
display when used with the 4000 in the DBLNTSC mode. Some monitor's give
you the capability of eliminating those black borders, but the NEC does
not.

Thanks!
I have 1/2 inch borders on each side of my screen, but that doesn't bother
me to much, (not yet anyway 😉
The pictures a lot sharper than any other monitor I've had though, I can
see the dither patterns in lores stuff, not to mention the scan lines on
15.75 non interlaced displays! By the way, what is the dot pitch?
Bob Comer — Cruising the nets on AutoPilot from Cheyenne, Wyoming
The NEC 3D has a .28mm dot pitch. Some of the other specs you might be
interested in:
.Sync: Horizontal: 15.5 kHz to 38 kHz
. Vertical: 50 to 90 Hz
.Resolution: Horizontal: 1024 dots
. Vertical: 768 lines
.Video Band Width: 45 mHz

I like this monitor more and more 🙂

Are there still any NEC 3D's in the channel? A friend of mine is monitor
shopping for his 4000/40.
//Jonathan,

I've seen adds for them on omputer Shopper, they go for about $400
dollars.
Great monitor!

Bob…
That there Computer Shopper is a mighty big book…June issue is, like,
over 800 pages. Can you narrow that down at all? 🙂
//Jonathan,
\\//via AutoPilot
I seem to remeber that one of the places selling the 3D are in the glossy
pages in the very back. (They also sell the Mitsubihi multiscans as
well.)

How good a monitor is the Mitsubishi Diamondscans? The only experience
with them that I've had is with a 20" one my local Amiga dealer had, and
it wouldn't sync down to 15.75, not to mention that I didn't care for it's
display. I assume that the 14" (or was it 13") one does sync down to 15.75
as it has a composite input as well as the standard input.

I haven't had any direct experience with a Mitsubishi montior either, only
second hand stories, and most of those were good.
I do have a 20 year old Mitsubishi TV that still has a better picture than
most TV's today! And I definitely like the Mitsubishi Eclipse 4wd Turbo
(Cool car!)

Robert,
Thanks for the information. Narrows things down a tad!
Jonathan
Your welcome!

That's USA Flex. They had the NEC Multisync 3D listed for $399. The ad did
say something about limited quantities.
Jim
Try USA FLEX… they advertise peripherals on the back cover pages of
Computer shopper and computers inside.
US Flex…last 5 or 6 pages in the book.
Gary (I bought my 3D there…good service!)
I believe at one time, USA FLEX was selling new and refurbished NEC 3D's
for a good price. You might have your friend give them a call at
1-800-444-4900 to see if they have any more available.

I just now called USA FLEX (I expected to leave a message on a voice mail
system), and was surprised to find that they operate 24 hours a day! Well,
they no longer have refurbed NEC 3D's, but they do have new ones, and they
sell for $399.00. What is your experience with this monitor?

Well so far it's been a real nice monitor. I've been using the same one
about 3 years now and not a glitch. Has a very good resolution and
display. The only thing that bothers me is that the horizontal display
area cannot be fully expanded to get rid of the borders when used with the
4000. But on my 3000, the borders were hardly noticable. Otherwise it's
been a real good monitor and highly recommended.

John,
Thanks for the information…I'll pass it on.

Jonathan:
I'm also monitor shopping. My Tatung monitor has died. I've bought a
Panasonic Panasync C1381i, however it's not really a multisync as the name
makes it sound, but rather an SVGA compatible monitor, so I'm going to be
bringing this one back to the store I got it from (not my local Amiga
dealer, he was closed this weekend), and try and get a better monitor.
Does the 3D sync down to 15.75khz, and how high does it go? Do you know if
it's possible to get a monitor that will sync from 15.75 to 72khz?

Mike,
As far as I know, its impossible to get anything "mainstream" with that kind of
range. It might be possible to get a "specialty" monitor to handle it, tho.
I believe that IDEK's 50xx series of monitors has the greatest scan ranges
right now, from 15-50 or 60kHz. The 5017, BTW, is particularly sweet, and a
pretty good price as 17" monitors go.
Jonathan
The Nec 3D syncs from 15.75 to 38. I love this monitor!
Bob Comer — Cruising the nets on AutoPilot from Cheyenne, Wyoming
John, perhaps your NEC's idisyncrasies could be corrected by some internal
height and width adjustments. My secondhand 3D exhibits none of those large
black borders–I have narrow ones on the left and right and virtually none at
all on the top and bottom edges.
What else might you want to know? For starters, don't try prying off
that panel at the rear of the monitor. It looks like it might conceal
some additional adjustment controls, but in fact, it's only there to
cover up some marks left by the injection molding process.
I don't have a manual either, but it seems to me that MODE is best
left in the OFF position. I seem to get better centering overall this
way and a lot less fussing around with the controls every time the
Amiga changes video modes on me. I think that the NEWER NEC models
might have multiple memory settings (one for each desired video synch
speed), but I don't think that the 3D does. However, I seem to be
getting very fine performance as-is, so I'm not going to complain.
I was just about to pry off that panel, Thanks! 🙂 Does there happen
to be a degaussing switch anywhere on or in the monitor?
There is no manually-controlled degausing circuit that I can see. Most likely,
it is fully automatic. If you've got greenish or purplish spots on your screen
because someone once put a big magnet too close, why not borrow the biggest
bulk demagnetizer than you can lay your hands on, and sweep over the screen?
Should work fine. Of course, it should go without saying that everything should
be powered down while being demagnetized 🙂 One of those handheld
demagnetizers the size of a small grapefruit should work great on this and any
hard drives or large collections of floppies that you wish to completly erase.
It's wierd, but for the first half hour of my 3D being on, there is a
slight discoloration in the bottom right, but it goes away after that.
I've never seen a monitor act quit like that before. My computers are on
all the time, except during storms, so it doesn't really bother me.

My 3D has a similar discoloration (more of a slight darkening). Mine
doesn't seem to go away but it is just barely perceptible and in fact at
first I wasn't even sure it was real or if I was just imagining it.
