I concurr on the monitors. I bought two new Dell's and got their 17" monitors
and gave them back for NEC 5FGs.

Hey Doug…
I just picked up a 5FG too. Do you notice any ghosting at 1024×768 while
under windows? I think I might need a better graphics card to push this thing.
Oh, edit your Navcis global.sig file to get rid of their commercial on your
messages.

Steve: Ghosting on these monitors is usually caused be improper
shielding on your cable. Most of the cheap monitor cables sold are
single shield cable. The best monitor cable should be ISP which is
Individual Shielded Pair. The type of cable would have a reference
of 3ISP plus 2 which is an ISP for each of R, G, & B plus H sync and
V sync which do not require shielding. All of the cables are then
jacketed in an overall shield. In addition the cable should have
ferrite chokes at both the monitor end and the card end. I had quite
a problem with this on my monitor / keyboard switch box until I
resorted to this method of ISP throughout including the switch. It
was quite a job custom wiring it all but was worth it to get rid of
the annoying ghosts.
Nice description of shielding! <G>

Don:
You're absolutely correct! I have a 6' extension cable connected to the
factory NEC cable. When I remove it, the ghosting disappears! Now, where do I
find an extension cable that meets the specs? I tried Cables To Go and they
don't have it. BTW, thanks for jumping in!

I've delayed answereing this because I've been at Comdex all week. 🙂
I asked about that cable at all the cable suppliers and they just drew a blank!
I guess your best bet is to do what I did and custom build them. I bought the
cable from a local supply house but it can be purchased atr any large
Electronics supply like Newark Electronics. The cable is also common to the
A/V business and is used to feed RGB to video projectors from computers. Check
with your local A/V service companies. The solder type (I don't like crimp
type) DB15 High density can be obtained from Markertek. or Newark Elect.
While Evan is correct is using the cable with BNC connectors it still won't do
if you have DB15 HD at each end.
IDEK vs. NEC? I think you asked about this troo. I chose it because of the
screen glare constantly gave me a headache. The Idek was easy on the eyes
after long viewing periods. I saw a comparison of the new 17' IDEK at Comdex
and they had it side by side with several others and the Nanao had it beat. Of
course at 1275 vs 799 the price was much higher. The Nec had richer reds but
still suffers tremendous screen glare. Of course if viewing in a darke room
this would'nt be a problem. Also the IDEK has a much smaller volume for a
given screen size than the NEC which is also a consideration here.
It has separate BNC and DB15 jacks that is switchable from the front panel.
The new IDEK also has the color cal. and memory capability. If I had to choose
a new monitor, though, I would spring for the Nanoa 21 inch which had the
sweetest picture I have ever seen.
Thanks for the info, Don!
How long have you been using the Idek? We have had some monitors
lose their brightness after a year or so. I'm not sure what causes
the problem, but it sure is a nuisance to have to take it in for
repairs.
I have a source for true coax DB-15HD to DB-15HD cables. They are
quite reasonably priced. If anyone is interested, they can contact
me via email, and I will connect them with the source.
Coax DB-15HD to DB-15HD? Where's the coax? <g>
The coax is in the cable. It provides impedence control and noise immunity.
Evan
Ah… shielded DB-15HD's.
Sorry, I thought you were going to throw a BNC or two in there
somewhere. <g>
Steve:
Get a cable with a VGA connector on one end, and BNC connectors on the otehr
end. It'll reduce the ghosting.
Evan
Are BNC sets more tolerant than standard HD-15<->HD-15?
I use my BNC sets on my VGA card now, and the standard HD-15 for the
SVGA… should I switch (it's no big deal…)?
Hi Evan!
The NEC 5FG's cable is built-in to the monitor, so BNC cables are not an
option. BTW, why did you choose the IDEK monitor over the NEC?
