Question regarding the new LG IPS panels

So I'm thinking of upgrading my Planar PX2611w - which is still an awesome monitor but I think I'm getting greedy for more space... so I'm thinking of grabbing TWO new 27" panels, the primary motivator being the higher native resolution for the new screens (2560 x 1440)

The NEC PA271W-BK seems like the ideal solution, but what I want to know is like the situation between the Planar PX2611w and the NEC 26WUXi screens (which effectively had the same panel) are there similar siblings of the new 27" screens?

Are they a significant or worthwhile improvement over older S-IPS panels?

Doublesight have a 27" screen that would appear to use the same panel that retails for about $800 but has some build quality issues, as well as a smaller UK manufacturer that I can't remember the name of.

I have to admit that while I don't have much of a problem with the TN screens I use at work... my previous life as a graphics guy has left me a little snooty when it comes to accurate color reproduction and banding artefacts for home use. I just figgered if I spend a few hours a night looking at the thing, I might as well get the best I can manage.

The only improvement is in response time. The AG coatings are still junk as are the contrast ratios and off-angle glow. I've personally grown tired of all of the flaws my ZR24w has (black levels are just awful, contrast is awful) and I'm looking to get rid of it soon and replace it with a *va panel.

As far as accurate color reproduction goes, that seems to vary wildly from panel to panel. You're basically playing the lottery with your money hoping that you get a panel that is uniform. Unfortunately 99 out of 100 are not.

Do you have a *VA panel you're looking at?

Yes, the BenQ EW2430 that is soon to be released. It's a revision of the EW2420/VW2420h, and should hopefully correct some quality control issues that the ew2420 was having. There's a thread about these displays floating around here somewhere

It's c-pva I believe, with 3000:1 static contrast--3 to 4 times that of modern IPS panels, and it seems to have an AR (anti-reflective) coating (not glossy, but clear), rather than a very aggressive AG coating like the LG IPS panels.

Response/input lag is really a non-issue for me these days as I don't play FPSs competitively online anymore.

It isn't only slower pixel response when you move to a *VA panel. You also have higher input lag, black crush and color shifting. I've owned a Dell 2707WFP, Dell 2709W (both S-PVA) and just upgraded to a Dell U3011 (H-IPS). I do want to point out that I didn't notice the black crush and the color shifting didn't really bother me. I loved my S-PVA screens when I had them but I wouldn't move back to them now. I quickly got used to the AG coating and the IPS glow doesn't bother me at all anymore. Granted I don't have much of a choice since all 30" montiors now use IPS panels.

There is no perfect LCD panel type right now but I would say that the move to the U3011 was a worthy upgrade.

Hopefully the BenQ EW2430 will be better as the EW2420 has a lot of issues with the LED backlighting causing a ripple effect on the bottom of the display. Also, while the 3000:1 static contract sounds incredible there are some reports of it causing significant black crush.

I was also considering a 27", but beware that in 16:9 format the screen height is almost the same as in a 24" 16:10! Unless you really have a reason to use the extra width, I see more value in using a 30". 30" monitors from Dell and HP are roughly the same price as the NEC, although this monitor should be no less than amazing.

Eizo SX2761W is S-PVA but that will set you back in a few more hundred$.

There is no black crush whatsoever with these displays. If you had bothered to look up some reviews rather than just assume things you would have already known this.

While I don't have any practical experience with this particular monitor I was basing what I said off of posts in this thread:

http://hardforum.com/showthread.php?t=1529765

As far as I know there isn't a *VA panel that doesn't have some level of black crush. It is a symptom of that panel technology. As I said before, with the two S-PVA panels I've owned it didn't bother me at all so YMMV.

The bigger issue noted in that thread that I would be concerned with is the ripple effect caused by the edge lit LED backlight.

There's a link to the Doublesight screen. It appears to be simlar to the Hazro 27" IPS panel reviewed over at TFT-Central, Here

Both these 27" displays run at 2560x1400, and have a 16:9 aspect ratio.

The 30" displays are really too large for my setup and they're also too expensive as my budget hovers around the $2k mark. I found the 16:10/26" to be a sweet spot for me.

I'm fairly sure I can remove LED backlit screens from the equation. I want a full gamut screen and the LED price premium really doesn't seem to be worth it until the technology is more mature.

I went from a 27" 16:10 display to a 30" and I can tell you the size difference is noticeable, but not as dramatic as I expected. I'm glad that I went the 30" route vs the 27" 16:9 route as the extra height is very beneficial.

I have a Dell 2709W and I agree. I have tested it on the Langon black level page and I can see every shade of grey, but the darkest 3 have a red tint to them. My one and only gripe about the Dell 2709W is that it is wide gamut, and does not have a meaningful sRGB preset. I have an i1D2 so I can work arround that when I need to.

Be aware that when some people say "black crush", they really mean "viewing angle gamma shift". They can get confused because VA panels are often setup to black crush extensively to help mask the gamma shift.

These AOU MVA paneles have extensive viewing angle gamma shift:

IPS panels are nearly immune to this effect. This is among the main reasons many choose IPS over VA.
