Interesting, they weren't on last night. I really wonder how it compares to the U2410

LED? Full array or edge-lit?
Because, you know, edge-lit sucks big time!
Is this downgrade from the U2410?
Looks that way
U2412M 6 bit e-IPS panel w/ LED backlighting, standard gamut ~82%
u2410 was 8 bit H-IPS w/ CCFL backlighting, wide gamut.
With 6bit panel, dithering is a real possibility.

Standard gamut is an upgrade for some people over the u2410, not everyone wants a wide gamut display, a lot of people should keep that in mind when suggesting one is "better" than the other. I personally do not want a wide gamut display because the support for it simply isn't there yet, so it causes more trouble than it's worth for the most part.
There are no full array LCD monitors.
But it is amazing how the misinformed opinions swing back and forth.
When LED first came on the scene, everyone was claiming that LED was so much better than CCFL. That somehow it increase contrast, improve black levels and fix backlight bleed.
None of which made any sense because in the end it is just a light source, just like CCFL.
Now when none of that turned out to be true we get opinion swinging the other way that now somehow LEDs cause more backlight bleed etc...
Which again makes no sense because LEDs are just a light source, just like CCFL and great many CCFL designs are also edge lit, but people just assume it is only LEDs that are edge lit.
Bottom line as always, LEDs are just a light source, there will be no immediate difference between LED/CCFL with regards to bleeding, contrast, black levels. Bleeding depends on quality of light spreaders/construction, contrast/black depend on the panel itself.
So Edge Lit/CCFL/LED make little difference to the actual outcome. It is all about execution and quality of design/materials.
RGB LED Backlighting - This type of backlighting is based on RGB triads, each including one red, one green and one blue LED. RGB LED backlighting ensures an excellent colour gamut and very pure colours, but is only really used in professional-grade displays such as the Samsung XL20, XL24, XL30 screens, and modern professional models like the HP DreamColor LP2480zx. This type of backlighting is only used in this sector due to its high cost and it is not economical to produce at the moment.
orly?
It is, but it doesn't necessarily mean it's a bad thing. If it turns out to be a 1920x1200 version of the U2311H, it's going to be a winner. Hopefully they don't screw up the panel uniformity.At its current price point I bet the U2412 is E-IPS 6 bit. But who knows I can't wait to see some reviews from websites...
What I don't understand about this whole E-IPS 6 bit plus dithering is. When people wanted to buy TN panels all the experts here and on other forums all said "Oh my God stay away from that 6 bit dithering crap colors are horrible on 6 bit" now that people have found out the E-IPS is actually 6 bit, the same people are now saying "Oh wait 6 bit isn't that bad" that is what confuses me

The cheap uncalibrated TN seems to match the calibrated NEC IPS pro screen for color!
Yes thats right. The "It's only 6bits" crowd don't have a clue what they are talking about. Normally when people drop a big load of cash on something like this they will try to justify it, but color IMO is not a justification. I poured through my collection of wallpapers and and test images and the that uncalibrated TN matched every tonal nuance of the expensive IPS on shot after shot. If TN has horrible color, then so does calibrated NEC 90 series IPS monitors. Or it could be that the "horrible 6 bit color" crowd are just blowing smoke.
I'm not saying that either claim is true/untrue, but you do realize thatorly?
Did you have a point? because it certainly wasn't obvious.
I'm not saying that either claim is true/untrue, but you do realize that
"That somehow it increase contrast, improve black levels and fix backlight bleed."
is not the same thing as
"RGB LED backlighting ensures an excellent colour gamut and very pure colours,"
...right?
I didn't say RGB LED is the same as edge-lit LED. I was trying to point out the obvious that contrast/backlight bleed is not the same thing as color accuracy. Snowdog said everyone claimed LED in general would increase contrast ratios & reduce backlight bleed, and DigitalViper-X replied with a wikipedia quote of how a specific implementation can increase color accuracy; an irrelevant reply/claim.RGB LED back light is not "edge" lit. which he said doesn't exist.
he's talking about full-array blah blah blah not existing but I'm going to assume he was talking about having actual back-lit LED, where you get a huge benefit over edge lit-anything.

actually, RGB-LED can increase contrast ratio as it can produce nearly black if not totaly-black / off crytals with localized dimming. My post had nothing to do with colour accuracy, had to do with the existing of RGB LED . Having the "black" light not on the edge also eliminates backlight bleed.

It also crushes blacks and creates inherent blooming. Not to mention that RGB-LED is not the same thing as local dimming and having one does not necessarily mean you have the other. E.g. There are Dell laptops with RGB-LED's that do not have local dimming.actually, RGB-LED can increase contrast ratio as it can produce nearly black if not totaly-black / off crytals with localized dimming.

RGB LEDs don't mean a full array capable of local dimming. Actually RGB LED has nothing to do with local dimming. You can have full local dimming arrays of W-LEDs or RGB-LEDs. This is why I asked you clarify your point before, because RGB-LEDs had nothing to do with anything I wrote.
There has NEVER been a full local dimming array of white or RGB-LED in a computer monitor and there likely never will be because of halo artifacts that would be much more evident in a computer monitor.
exactly how do you achieve local dimming with w-leds? it's not possible. not locally anyway.
lets say you have a rectangle with 200 equally spaced LEDs. You dim one of those 200. ta da!
? W-leds are generaly edge lit, you don't have 200 you have 2 or 4, on the edges of the panel
oops, my on the w-leds, that's just white, not edge and can still be used in led matrix back lighting.
Anyways again. my point was that full array lcds don't exit, and that full array LEDs do, at least in marketing speak.
I think we've derailed this thread enough. all from a single orly ~.~
Mine is coming this week, behind high hopes and crossed fingers. I'll be the guinea pig. This is my first LED backlit IPS monitor, and I'll do my best to post as much info as possible including potentially higher refresh rates over DVI, input lag, contrast ratio, gamut etc....
It's arrived at work. If I have time to pick it up before my softball game, I will. If not I'll go after the game tonight and hopefully get down to business barring defects or other issues.
