The "best" attribute of VA technology just happens to be it's major flaw. Sure, they have great black levels, at the cost of crush. What's wrong though, is they only crush when viewed head on. The outer portions of the screen have more detail and don't crush while viewing head on, so that there is what appears as a "shadow" in the middle of the image. This is especially evident on grey backgrounds and dark images with uniform horizontal detail.
IPS have no issues with backlights, they use the same backlights as all other panel types. IPS panels have traditionally not blocked the backlight as well as VA, thus black levels have suffered. But that has been changing, the new H-IPS in the HP LP2475w has produced some of the lowest black levels when calibrated at or near 120 cd/m2...

"Best" is truly subjective, but there is no denying the flaw of VA technology. Some people are not bothered by it. But my money is on people that sit 2 feet in front of a monitor are going to notice it, and eventully get sick of it if they care about image quality.
Now on a TV that you sit 10+ feet from, it's not as much of an issue when sitting right infront of it anyway.
In regards to backlighting on IPS, I was not referring to what they use. I was referring to overall uniformity. Backlight uniformity of them just aren't up to par. Most VA panels I've seen have better uniformity.
I don't notice "black crush" on my 305t. I do heavily notice black crush on an older 21" samsung VA monitor I see my friend use (it's pretty bad on that), but I can't notice any on my 305t. It looks great...
You should stop posting comments on posters instead of posting on the topic.
My attitude is tests, measurements, pictures and videos.
I've posted links to illustrate that 2x2=4.
Neither 2709, nor 305T are any different in that regard - same PVA with black crush and colorshift.
It's not a matter of opinion - this is how a particular technology is designed. ABCs of LCD.
Opinion? Here you are.
In my opinion, 27"PVA (Dells, Samsung, Eizo) are good monitors. I like them. They occupy a certain niche in screen size and dot pitch, capable of relatively good colors and viewing angles, good for blu-ray and PS3, etc.
But one should be a zero noob to deny facts about standard limitations that panel technology puts on them: black crush of dark tones (can be relieved by screwing gamma curve at the cost of whiter black and lower CR), colorshift from vieving angles (not curable), color gamut issue.
If you can live without quality "printed photo looking" picture - those are stiil good in my opinion (even with PVA limitations).
Sorry, we cannot debate LCD basics in every thread. All tutorials are published already.
Detailed review of a PVA monitor.
If someone believes that 2x2 is not 4 - that's someone's own problem.
First of all, you are part of this THREAD, and you are part of the topic, so comments on how you comment on LCD technology are fair game.
Second of all, I KNOW about the limitations of VA technology. Yes, I do notice more colorshift on my 305t than my former IPS monitors. I did not deny that or some of its other limitations. There's a difference between you and me, however. You're the type of person who'll actually sit down and look for defects in your monitor and criticize the hell out of it to the point where you can't use it to get your work done. I just look at a monitor and see if I like the picture, and if I do, I'm good to go. I'm not going to sit there and look for shit and go "OMFG the colors shifted when I moved my head 10 inches to the right."
Look, in for the most part, LCD technology has several limitations, no matter what panel type. So once again, I will get what looks BEST to my eyes. You will not find a perfect LCD monitor, so you get whatever you like best for yourself.
Hell, a person could come out and say they prefer TN panels because they like the look of the inverted colors from wide angles because they "look cool." While, technically that is a limitation of a TN panel, someone else could look at it as a plus and prefer it. This is what I am trying to get to. People can live with certain things and prefer some things over others, and what is best is truly subjective. No where did I deny some of the limitations on certain panels.
For me, my biggest things are no aggressive antiglare coating that looks like dirt (which most IPS panels have), good backlight uniformity, and good blacks. So from my point of view, VA panels are better for my needs, and I'm willing to live with the limitations of VA panels (even though with any LCD panel type there will be limitations you need to deal with) But I will say, I view my monitor head on, so the worse viewing angles don't really matter to me. I also do notice if I look at a single block of color across the screen, the color will look very slightly different on different sides of the screen (no surprise as it is a 30" monitor) But I've seen that from IPS panels...and even crts. Nothing has been perfected yet, so that is why I think people should just get what they prefer, and there is no such thing as "best."
