Color uniformity? or backlight uniformity?On a side note: I have noticed that uniformity of my monitor is at its worst when first powered on. Any tint appears to fade after about half an hour of use. The backlight obviously needs time to warm up.
I have heard reports from other people that have uniformity issues that their monitors appear to get better with this problem over time. Maybe IPS monitors need to be worn in?
Same here. I have to say I did not notice it (not even when I was checking the uniformity) until I used one of the dead/stuck pixel test images. I tried JScreenFix for 20 mins. Did not help. Not sure if I'm brave enough to try the other way of fixing...I've checked the backlight on a black image and I do not see any problems. It looks 100% uniform. The only problem I see is a stuck pixel - it's red on a white background or black on a darker (blue) background. I'm going to try one of the stuck pixel videos to fix that.
Color uniformity? or backlight uniformity?
I'm using TFT Centrals color profiles and it looks great - Native, 60 brightness

Interesting, thanks. I did notice on the bluer side of my monitor that the color temperature was higher, but I seem to recall that the luminance was actually lower than the right (warmer) side. I'll leave the monitor on for a few hours and re-measure to see.AFAI am aware the colour bias which appears on screen is causally related to uneven backlighting.
So for example pink tint on the right side of your screen, this is actually a result of the backlight being dimmer on one side of the screen compared to the other. When you measure the screen with a calibration device you should see results along the lines of: lower luminance on the right side of the screen with a correspondingly lower Kelvin figure for color temperature and hence warmer (or redder -> pinker) looking colour.
The reverse applies when you have a green/yellow tint on the other side of the screen -> brighter backlight -> higher luminance->higher colour temperature-> bluer/greener colour tint
Amateur explanation I know, but then I AM an amateur (and learning as i go). However you can read up more about this on eizo forum's,luminous landscape forum, prad and tftcentral (and I think also dpreview forum).
Some quite knowledgeable people and their explanation for colour bias on screen is similar to my own admittedly fumbling explanation.
Don't you find brightness at 60% too bright?![]()

20 min was the suggested time on the instructions. Altough I was already planning to do a longer run later.You're gonna have to leave it on for longer than that. I had a stuck pixel on a BenQ TN panel:shudders:
I tried out last year. Left JScreen on for a few hours and it seemed to have largely went away.
Well...I was doing a bit of post purchase validation last week.
Yes I was already happy with my monitor but I just had to see how it compared etc etc. Confirmation and all that.
Well I thought I would mosey on down to the local store and check me out some NEC 2490's again. I was considering these at one stage and they were/are reputed to be the best displays ATM.
Ultimate comparison? Maybe
Preparing to be let down by my NECEA231? You betchya
Now before I continue let me just say that pic quality of the EA231 was in my head but I see it everyday so its kinda fresh and I tested veiwing angles of the monitor to excess.
Talk about post purchase validation!!!
I don't know whether I was shocked at the less than stellar image quality of the 2490wuxi x5 or whether I was rapt that my EA231 (in my mind at least) matched the 2490wuxi in picture quality/viewing angles/graininess.
The NEC 2490wuxi upon close inspection did have grain and compared to EA231 looked to be about the same level of coating. IOW grain would not have been avoidable by going the NEC 2490 route.
Viewing angles: Wow. This is were the 2490 is supposed to shine esp. with the A-TW polarizier. So disappointing! At 170 up/down left/right I was seeing a semi washed out picture with (and this is hard to believe) white glow! Does the A-TW polarizer need to be turned on/activated or something? Maybe the shop forgot to do this with their 2490wuxi's?
Because viewing angles sure weren't better than the EA231wmi and on reflection may have even been worse!
Picture quality head on was about the same. This was a tie. I could not seperate the monitors. The EA231 would have had to be side by side to discern any differences.
Needless to say I am grinning.And I re-asses my view of the NEC2490wuxi. The Apple Cinema Display is the king of the pro monitors (but its Apple EWW!
)
And I re-confirm my opinion that the 2490wuxi is overpriced (cos the advanced electronics don't seem to making for a better picture).
For those claiming 100% uniformity: pix or it didn't happen
Hmmm... are you really sure it was the original 2490 and not the 2490WUXi2?
You can find some photos I took of the one I got from Provantage a few pages back. Basically, it's got some bad color uniformity problems, but otherwise is alright. I'm exchanging it, though.For recent purchasers of this monitor:
Did anyone buy from provantage? If so, can you report on the quality of your display? Mine shipped out from New Jersey, should be arriving tomorrow.
I'm seriously thinking about getting this monitor, but I have a quick question. Can this monitor do 1920x1080 @ 75hz? The reason I ask is because 75hz on my old LCD almost completely removed tearing without me having to use vsync.
Bad news: I can't get it to do 75 Hz at 1080p over DVI.
Good news: It can do up to 74.6 Hz at 1080p over DVI and 81 Hz at lower resolutions without skipping frames! It can also do 81 Hz at 1080p over VGA, but VGA is a bit blurry. I bet it can do 81 Hz at 1080p over DisplayPort, but I don't have a DisplayPort card. I will get one to test this.
These are the timing parameters I used to get 74.6 Hz at 1080p:
Horizontal active: 1920
Horizontal front porch: 25
Horizontal sync width: 35
Horizontal back porch: 45
Horizontal total: 2025
Vertical active: 1080
Vertical front porch: 3
Vertical sync width: 4
Vertical back porch: 5
Vertical total: 1092
You can also use those settings to do 72 Hz at 1080p.
For 1080p at 81 Hz over VGA, I just used the default timing parameters:
Horizontal active: 1920
Horizontal front porch: 88
Horizontal sync width: 44
Horizontal back porch: 148
Horizontal total: 2200
Vertical active: 1080
Vertical front porch: 4
Vertical sync width: 5
Vertical back porch: 36
Vertical total: 1125
You can also use those parameters for lower resolutions over DVI, like 720p at 72 Hz:
Horizontal active: 1280
Horizontal front porch: 88
Horizontal sync width: 44
Horizontal back porch: 148
Horizontal total: 1560
Vertical active: 720
Vertical front porch: 4
Vertical sync width: 5
Vertical back porch: 36
Vertical total: 765
That also works for 720p at 81 Hz.
This monitor handles the PlayStation 3 perfectly without screwing with the colors or distorting the aspect ratio.
1080p is perfectly 1:1 mapped without any banding or distortion, no 24 Hz support though
1080i is supported but the deinterlacing isn't great
720p is scaled properly
480p can be scaled to 16:9, something most monitors can't do, but aspect scaling is still 3:2
None of the modes have overscan.

They are an authorized NEC dealer and last I checked had it for $327.41 free shipping.
That is where I got mine from. They seem to be a great company.
So I went ahead and got two NECs from pconnection.com for $659.92 ($329.96 each) with free shipping + no tax. They say they won't get them til the 6th, so I'd have to around two weeks before I get them.
Hey guys!
First, has anyone come across any noise issues with the monitor? Specifically, when you turn the brightness down passed a certain point? I ask because I just took back a Samsung 2494HM that produced a nasty hummmmm when turned below 88% brightness.
Thanks!
Looks like Buy.com dropped the prices on the monitor to 307.99. I emailed them and asked for a price adjustment since I purchased mine for 341. Just got email from buy.com saying they would honor the lower price.
Buy.com is being accused of deceptive billing and privacy practices (also see here), so you'll want to be careful. They certainly won't get my business.Just to keep those updated and informed: I've made my decision to try my hand at the lottery and am returning/exchanging the NEC (via Buy.com) for a new one in hopes it either has less uniformity issues or none at all.

I noticed TFTCentral's panel database now lists "LM230WF2 -SLA1" for this NEC. I am fairly sure when I last time happened to check it, only "LM230WF2" was listed (same for ViewSonic VP2365wb and still is - without "SLA1"). What this "SLA1" means? I noticed some other LG panels have "SLA1" and "SLA2" too, so I guess this additional model name comes from LG. But what it means?
For those of you that are interested, Amazon has this monitor at $330 with free shipping. Picked one up, we'll see how it goes.
Best deal out there for those of us in California right now.
