NEC 20WMGX2 Backlight Bleeding

I recently purchased a NEC 20WMGX2 and after setting it up noticed there appears to be some screen uniformity issues (backlight bleeding). I also noticed one "dead" pixel and a small "smoke-like" imperfection (difficult to explain) behind the screen located within the same vicinity as the "dead" pixel.

Would anyone mind posting a few pictures of their 20WMGX2 with a blank screen saver with no ambient/direct light nearby? I realize the effect is somewhat difficult to capture with a camera, but I would like to determine if the uniformity problems I am experiencing are really bad, or if I am am just being picky. It would be much appreciated.

Thanks! :)

(I took some pictures tonight of the backlight bleeding, but they didn't turn out that great. I will take some more tomorrow and upload them.)
 
When the 20wmgx2 first came out people complained about lots of screens not having good back light. The newer ones seemed to have been made better or something, what ever they started to do differently. I have two of these panels and both of mine have no bleeding but if your thinking yours is bad enough for you, then i would suggest trying to change it out because for all you know once you have used it more, it could get worse or if yours is like the older 20wmgx2's yours could get better, who knows. If it was me i would take it back right away so you know you can get it changed with out any hassle.
 
Just bought this one new from the egg, been using it for a couple of weeks now. Pic taken with camrea set to manual and zero exposure. It is on and displaying a black background on UDPixel. The LED is set to 10%, Brightness to 50% and Contrast to 50%, Color on Native, DV is Standard, ADV is off.

The "smoke" spot might be where some one tried to rub away the dead/ stuck pixel.
 
Here is a pic I took last winter when I got first 20WMGX2. I left shutter open a bit to pick up any pattern in overexposure. I found screen to be relatively perfect compared to other LCD's I had. When I did this to my Dell 2007WFP with the S-PVA all the corners were on fire. I did get one 20WMGX that had a bad panel all around (backlight bleed, stuck pixel) and NEC replaced it with a display that had bad image persistance. Then they replaced that one with another perfect one so all was well that ended well. I don't care about dead pixels much but a stuck one is a no-no on a new monitor. The NEC's can break-in after a week or two. Even my good ones calibrated better.

 
Sorry for the late reply!

Thanks vick1000 and abcdelight for posting pictures! Very much appreciated. I wanted to also post some pictures but have been unable to take any that really capture the screen uniformity issue.

At this point, I'm not sure what to do. I purchased the unit from an online retailer that will not accept a return on an opened item and does not currently have any units left in stock. (I suspect they will not be getting more any stock ever again as the item has recently been discontinued). I'm afraid that I will have to send it to NEC directly and will be sent a refurbished unit as a replacement... I didn't spend close to $600 for a refurbished monitor.

Any suggestions?
 
I got a bad NEC once (backbleed/stuck pixels) and they sent me a new one. That one was bad too (backbleed/damaged panel) and they sent me another new one. That too was bad (bad image persistence) and they sent me another new one - which was perfect. This was about 2 months ago. They seem to have new ones available still. Thye told me they dont get many returns on the 20WMGX2. I probably ran into a bad batch and the end of production or something. I find tech stuff can be like that these days. Right now there are some bad memory chips on video cards. You just go with the good dealers. NEC was easy to deal with and did as much as I could expect them too. In my NEC boxes they said to call them directly instead of seller anyway. Call'em up then.

Thanks for the prompt reply and info! Just out of curiosity, was there anyway for you to verify the replacement units you received were new? (Did NEC suggest they were new or were you just able to tell based on the packagaing etc.?)

Thanks again. :)

Each time I called NEC the person I got (and I had several) said my problem was with a new monitor and they specifically said they would submit I get a new monitor in exchange for one I had. I never had to ask. I never checked the menu for the hours used or anything but last monitor looked new and unopened and worked so that was good enough for me. I will add the defective units were all black and the last one they sent me was white/silver. I liked the white one better (looks wise) then the black one I bought so I just kept it.
 
I called NEC and was told they had no more new units available for replacement (only refurbs). However, they did say they were "on order" and were unable to provide me with a date as to when they would be received. This model, of course, has recently been discontinued, and I dont have faith that they will be getting any additional new stock. If they were to receive more units in (God knows when/if it will happen), they will gladly replace it.

I will not accept a refurbished/used unit, so I find myself in a dilemma. NEC gave me a case # and has the monitor listed in their system as DOA. The reseller (Provantage) from which I purchased the unit has no more in stock. It seems as though my only choice is to contact Provantage and request an RMA for a "defective/DOA" item and pray they refund me in full before my 30 days (to return) runs out. To top it all off, I have a $100 MIR for this unit which needs to be postmarked within a few days if for w/e reason I have to keep the defective monitor. :mad:

Before I make any moves, anyone have any suggestions?
 
If they won't give you a refund, send in the rebate and deal with NEC. If all else fails, let NEC ship you a refurb and hope you get a good one. E-bay the one you have and try to recover some of the money (maybe more).

Or if your nuts like me...

You could take it apart and try to fix it by taping the edges under the metal frame. I took mine apart to blow the dust out from under the panel, and seal it up to keep out more dust (seems this model is quite open and succeptable to dust getting behind the panel). What sucks is, I got rid of what I thought was a dead pixel, but I missed/ moved a spec of dust to another location. I will have to do it all over again eventually. I know, I'm crazy for taking apart a brand new $360 (after rebate) monitor with no diagrams. It was really easy though, most all LCDs are assembled the same way.

Too bad they are out of units. Did you buy a black one? You could always ask if they have the white one still - or vice versa. They sent me a white one the last time (I had bought black) and I ended-up liking it better. "Refurb" means different things. I have seen people get refurbs that showed very little hours of use in service menu and worked perfect. I doubt they would send out a unit that was used much - probably not at all really. I would try the refurb myself if all else had failed. You would still have 3 year warranty and it would probably be good unit even if you were picky. Don't worry about the rebate. I sent my last one 2 months late because I had to send monitor back. They still redeemed it (I did include a letter and case number).
