NEC LCD20WGX2 review *** UPDATED 25/02/06 ***

Lately, I noticed that many people as soon as they discover that some monitor is based on the S-IPS panel they are confident that monitor will produce the equal performance as NEC. At some places, I even noticed that Dell 2005/2007 is quoted to use the same panel as NEC. It's definitely misleading. I would like to clear such possible confusion and give some right directions on this matter.

Yes, they are sharing the roots of the same IPS technology (S-IPS) ... but panel type is not the same; Fair enough, S-IPS are excellent panels capable of brilliant performance (and they are my favourite) ... but NEC is based on the AS-IPS (A = Advanced S-IPS and it may be related to DVM ... I think, but not sure) and it's faster as it's boosting the impressive 6ms g2g. In other words, NEC panel is using the improved (or different) overdrive and completely different panel control circuit because of the Advanced DVM. FYI ... even Dell 2005 is using the LG.Philips S-IPS (LM201W01), but it simply can't match the NEC performance and display clarity. In some sense, sometimes it's not just enough that people focus on the panel type or origin strictly. Improved overdrive or advanced panel control circuit my bring the surprising results also.

Anyhow, what is interesting about this monitor is that even in direct comparisons with the standard S-IPS panels (like Dell 2005) it definitely delivers the stronger picture performance in the terms of image clarity, colour reproduction and deepness, black levels and contrasts. Surprisingly, this is even happening with the stock monitor configuration and without the Advanced DVM enabled. I know that credit have to go partly to the OptiClear ... but this is not the major player. Somehow, I'm starting to believe that they maybe changed something in the AS-IPS panel itself (apart from the electronic control circuit) as this monitor even at the stock setup and without the Advanced DVM is above the S-IPS competition.

Unfortunately, no "downloadable" tech spec is available for the AS-IPS. I collected some statements from the manufactures itself about the AS-IPS. Quite possibly, it may confirm my theory from the above.

"
The advanced super(AS) -IPS mode system for use in televisions, large-screen monitors and other applications achieves an approximate 30% improvement in the aperture ratio over conventional IPS technology. Furthermore, AS-IPS realizes a higher level of brightness and reproduces colors more realistically thanks to high-purity color filters and other proprietary technologies.
"

"
This unique design ensures consistent illumination, excellent color performance and optimum contrast-even at wide off-axis viewing angles.
"

It may quite possible happen that CCFL backlight tubes have also been replaced in NEC by a new generation which is capable of a wider gamut.


At the end, here is some interesting comparison between the Dell 2007WFP and NEC LCD20WGX2 (response times & colour reproduction):

Could not agree more I've not seen a monitor produce a better image than the this NEC panel, it just makes everything look so much better, especially the advanced DVM. :)
The only monitor for me that I might buy over the NEC would be the 24" DELL and thats plainly just because the DELL is bigger, but the NEC is faster and gives a better picture. :)
 
Just now bad is this “noise” that I keep reading the overdrive causes in DVD playback?

I plan to be either buying the Viewconic or the NEC and this is the only issue stopping me from getting the NEC.
 
oh my!

heres a new one:

Been using my LCD no probs for the past week or two (except the bleeding in the left corner) and its been perfect - something REALLY wierd keeps happening now! - the LCD just switches itself off whenever it feels like it!

Used it fine last night till 0:00 - come today I start to reinstall BF2 - all went well - had to run it at 1400x1050 (closest I could get) - then suddenly the TFT started to switch off and back on again!.

I tried all sorts - tried the other video input (analogue) and same thing - monitor would sometimes switch on and off! - Idea - reset to factory defaults - did that and it seemed to be working ok again! Just in middle ot typing this and the screen went off again and back on! - :( :( :(

anyone else had any similar issues - i'm suspecting a dodgy DVI cable - but can't be too sure as I havn't got another to try - currently its very dodgy - sometimes off sometimes on :(

I'm glad I took your advice on the NEC. My mate has the 24" Dell, and it's nice, but the picture is no where near as nice!!

The last time I saw a screen with this kind of picture quality was my last CRT (a Sony Trinitron). I have a Hitachi CML1745SX running next to the NEC, which I used to think was a great TFT......my good, the picture is rubbish and the ghosting is very apparent :p

Amazing what your eyes get used to really...

i have'nt heard any noise during dvd playback, must say i'm impresed with the screen quality, picture and all that, like most the backlight bleed is there mainly left side with bottom left the strongest.
gonna leave it and see if it goes away.
overall very happy so far.

LOL ... mercyless such noise (and overdrive itself) is not the "audible" thing. He is referring to the "visible" noise, pixel pitch, twinkling or however you may call it ... during the movie playback ;) It's known phenomenon all LCD monitors suffers from (even LCD TVs) to some extent and it may or not be related to the overdrive ... but usually to the panel itself. It was already covered in this thread.

Movie playback was acceptable & pleasant for me, but watch your movies from the relative distance.

how does my website look for you ? it should be cool nuetral shades from white, supposed to look like paper not like yellow paper, I can calibrate the RGB amounts on the nec however this then tends to screw up mid tones, when I aim for my white.

Not sure what to do, backlight not an issue any more, but colour reproduction is important to me, what should I do ?
Click to expand...
Looks pretty much white here, almost "alpine" white. No yellowish traces. Not sure really how come that you have such drastically different representation of this colour spectrum. Do you use custom icm/icc colour profiles in the windows itself? Monitor backlight colour can be responsible, not sure really ... If you like the "cool" colour tones (especially white) did you try the 8200K or even 9300K colour temperature monitor modes ?

It just seems that any screen that makes use of an overdriven-overdrive has issues with DVD playback for some reason.

Up till now I have been using the original Samsung 710T TN 16ms which for a 2yo (Released just after the 172x) monitor is STILL up to the job is ask of it. No backlight bleed and certainly NO dead/lazy pixels means I have to force myself a bit :(
 
has anyone had any further response with regards to the bleed problem?

I tried ringing NEC on the number we used to contact them before - Sorry the number is no longer in service!

EDIT: looks like they're still waiting on an answer from JapanNEC, personally i've got a replacement due tommorow for my 'other' problem though.

OK ... if anyone would like to colour stress their NEC monitor, I uploaded some scenery pictures from my Thailand holiday quest :) I think that Raymond Lin is involved in photography, so he may find this interesting too ;)

http://62.204.32.7:10973/TH2006/

All of the pics are scaled down to 1600x1200 from the massive 2272x1704 original format.

Enjoy.

** EDIT **

Related to the pictures from the above post, some of them are looking just stunning on my NEC and they are definitely stretching the muscles of this monitor to some extent, showing up the monitor capabilities in full glory. There is a great sense of picture "depth", and wide colour gamut & contrast is greatly present on some pictures. At some point, you really feel that the figures from the first couple of pictures will jump off the screen any moment. Just great ;)

I am very close to ordering one of these. Being a tall guy (6'3") I was wondering how high the top of the screen is with the stand at maximum extension (if the stand is adjustable)?

Thanks.
 
Backlight bleed for me has calmed down a little more. Just a slight amount of bleed left on the bottom left hand side. Not really an issue. I have no dead pixels that I can see so think I'll be keeping hold of mine.
I have to say that gaming is excellent on this monitor :D

I'm relatively tall guy too ;) Anyhow, it's fine for me and I have pretty much standard working desk. Yes, stand is not height adjustable but you can tilt the monitor. If the issue is extreme, you may:

a) Purchase the adjustable chair :D
b) Purchase the LCD monitor arm and have really free style monitor movement
c) Use the additional stand (support) for the monitor
 
ok got mine today and its very good ,seems so much bigger than my old benq 17 inc TFT there is slight bleed on bottom left but it does not show in game or on desktop overall very nive monitor if your thinking about buying one do it im glad i did :)
