Considering that S-IPS are the Holy Grail of screens, especially for people who value image quality and accurate color reproduction above anything, I was wondering if a S-IPS screen would always outperform any M/PVA screen?

So in terms of IQ and accurate color repro:
Best S-IPS vs. Best M/PVA screen | Best S-IPS wins

But:...
Best M/PVA vs. Average S-IPS screen | Average S-IPS wins?
Best M/PVA vs. Poor S-IPS screen | Poor S-IPS wins?

Or is it that an excellent (and expensive) VA screen can outperform an average (and cheaper) IPS screen in terms of IQ, viewing angles and color reproduction?
:confused:
 
Most IPS panels will have better calibrated defaults, and more acurate dark tones. Of course it all dpends on the individual panel, as of course they vary greatly even in the same model line.

For a more detailed explination, you will have to define your terms. What constitutes poor, average, and best to you?
 
I think your going to have to give some examples, be more specific.
What displays are you comparing, thinking about buying?
 
No, I actually want to keep this topic generic instead of boiling it down to 'screen brand model' vs. 'screen brand model'.

You hear everywhere... when it comes to color reproduction, lack of color/gamma/tint shift, the S-IPS panel is the best. So for photo editing etc. you really ought to get a S-IPS screen.
A lot ofcourse is based on the excellent LCD thread at Anandtech.

So this made me wonder if it always is the case that a S-IPS screen will be better in terms of IQ and color repro and therefore more suitable for photo editing and other professional design purposes. Or is it much more an issue of the viewing angle that makes the difference?

Or is it very well possible that a cheapish S-IPS screen (you can fill in the brand yourself) will be outperformed by a high-end and expensive PVA screen (fill in high-end brand name like NEC, Eizo, LaCie etc.)?
Ofcourse for the sake of discussion, I am puting it rather black and white. But I am very curious about your opinions!

* VA
o Decent response time (varies)
o Great dynamic range (1000:1 - 1500:1)
o Horizontal color shift (certain gray tones rapidly shift at just a few degrees, worse than TNs in many cases)
o Image details absent at perpendicular angle
o Good vertical viewing angle

o Good screen uniformity (white is uniform and does not shift at angles, contrast is decent)
o 8-bit gradient (16.7M colors) through true 8-bit DAC (although dithering is possible with certain models)
o True 8-bit DAC allows better reproduction of gradients and sometimes better dark tones than TN panels
o Unlikely to get image persistence
o High input lag (high latency in screen update)
o Good value, and the least QC problems of all panels

Target Audience:

Gamers, general use (Word/Excel) who want a more stable viewing angle. OK for photo editing, although beware of color shifting. Not bad for movies, but not always great due to color shift.


* IPS
o Decent response time
o Medium dynamic range (400:1) or higher for AS-IPS/H-IPS/A-TW-IPS (700:1)
o Minimal color shift at any viewing angle (only slight brightness reduction, and very little gamma/tint shift)
o Image details present across entire screen
o Good screen uniformity (white is uniform and does not shift at angles, contrast is amazing)
o 8-bit gradient (16.7M colors) through true 8-bit DAC (although dithering is possible with certain models)
o True 8-bit DAC allows better reproduction of gradients and sometimes better dark tones than TN panels
o More neutral grayscale reproduction and warmer, less harsh image (most like a CRT) than S-PVA panels
o Medium input lag (low or high depending on model)
o More susceptible to image persistence
o Tends to be very expensive although benefits can be visible to normal users
o Prone to quality control problems: read reviews

Target Audience:

Photo editors will crave this type of panel. IPS-type panels are suitable and generally better for anything else too, including gaming and general use. Some people may prefer an S-PVA for higher dynamic range but an IPS panel, due to its viewing angle characteristics, probably has a higher contrast (ability of the LCD to reliably reproduce tones and nuances).

Feature wise its going to be a wash, S-PVA will always have things S-IPS won't and vice versa. Both technologies are improving to the point that an S-PVA probably has better color than a S-IPS 4 years back.

Although most high end S-PVA seem to be used a lot in professional displays, I've heard reports that their visibility is one of the worst. I don't know how to describe it but it has a sparkly or grainyness to it that makes it very hard on the eyes. They say that it has to do with the quality of the production and that by contrast the ASV panels by Sharp is the easiest on the eyes. The same problem can be seen with S-IPS by LG Philips though this problem has went away with H-IPS. I think that performance wise you won't see a huge difference between the two, but the H-IPS should cause less eye strain.

I can vouch that S-IPS has a grainyness that I can see in solid colors(whites and light colors), it can't be the matte because it's too fine. The TN E207WFP has significantly less which is also matte.
 
It depends on the category you are evaluating,

VA type screens have better (or darker black levels, but worse "straight on" dark detail. When you shift your head left and right you see dark details better on the VA panels as compared to straight ahead, whereas with S-IPS, until you move your head left and right things don't really change much.

Some S-IPS panels have a slight violet tinge to things on somewhat extreme and close-up viewing angles, but that's mostly only seen on very bright, or very dark screens.

Probably the ONLY other category (according to my personal taste) where S-IPS isn't as good is in the panel smoothness, but that varies with vendors. I find my S-IPS TV from LG has a very smooth panel with just the right amount of anti-glare, whereas my Dell 2005FPW is a bit more grainy or sparkly. This varies due to amount of anti-glare coating applied.

For color reproduction, if the S-IPS panel is decently calibrated regarding gamma levels for each color, it is definitely best.

For response time I find S-IPS to be great, better than VA with overdrive and without. Running the response time test on www.lagom.nl, my S-IPS screens have handily shown less color shift on the blinking boxes. Only TNs may outperform in this regard. Input lag can vary but S-IPS can come very close to TN, especially when heavy overdrive is not employed. VA with heavy overdrive can be really laggy.

Subjectively, viewing angles on S-IPS displays are best. VA is close, but on angle performance is not as good, and grey sometimes looks silvery (such as the hardforum background).

For bright and vibrant colors, and highest contrast ratio, S-IPS does not match VA panels but accuracy out-of-box always seems better.

Quality control of S-IPS can vary. LG has improved in that regard, and from personal experience I've never had a S-IPS panel with a bad pixel ever, but stories will vary. My LG TV is devoid of clouding or mura, and backlight bleed is near non-existent, as is the panel on my Dell 2005FPW.

Ultimately, I like S-IPS best, but it really comes down to personal taste. I also have a 24" TN that I like and cannot see dithering or FRC blinking, and a 24" A-MVA that I am happy with, but my favorite is still IPS.

I would take the worse IPS panel ahead of the best VA panel, since I consider VA panels unusable do to this:

And in reality since IPS seem to be the most expensive panels to produce, they don't make it into many poorly done monitors.

I swear... if one more person links to that retarded picture I'm going to shoot someone. That picture shows how crappy the 2407 HC viewing angles are, but it does not represent *VA technology in general. My L246WP (P-MVA) doesn't shift anywhere near that bad.

That picture may be a worse case scenario, and few have seen anything that bad, but I bet if you placed the 2407 and L246wp side by side and compared a number of images, they would shift in a very similar manner. After getting burned by the 2405 and 2007fp, I checked out a number of monitors in stores and the MVA screens were just as bad, if not worse than PVA screens.

When I complain about the gamma shift in *VA screens(without being specific to PVA/MVA) I invariably get one of two responses:

PVA owners stating that it's MVA screens that are very shifty and their PVA is fine.
MVA owners stating that it's PVA screens that are very shifty and their MVA is fine.

In my experience there is practically no difference to the *VA shift, just varying degrees user sensitivity to it.

IPS is the only screen type I would consider for imaging work and if I wasn't doing any imaging work, I would consider a Cheap TN screen like the the Benq G2400W, because it will be lag free, fast responding and less shifty in the horizontal than *VA, and much less expensive.
 
I've been curious about this also. I'm stuck right now between a high end PVA (LG 246WP) or a lower end IPS (DS-263N).
 
Alright, due to the fact that my camera blows and I just blew up the image from that website in paint, we are NOT comparing image quality and colors. The purpose of this shot is to compare gamma shift...

And if you had the Dell and took the same picture, under the same conditions, it would look very similar to your LG picture. I have no idea what he did to get the Dell image, because as much as I dislike VA screens, I have never seen anything that bad.

His movies (on the link I included) probably more realistically illustrate the problem.

I agree that the Dell probably has about the same amount of gamma shift as the LG. I'm just trying to show that there is something whack about the picture on that website and it does not properly illustrate *VA gamma shift.
 
Before I post the next picture... let me first say that I think most IPS screens are better than most *VA screens. However, I do think that on occasion a nice *VA screen can be better or on par with an old or mediocre IPS screen. Apparently a lot of older and cheaper IPS screens have a white or purple glow to them when viewed from an angle.

EDITED: verylostindeed thinks his monitor is messed up so I swapped the image for this one.

i would agree about that pic - the benq in my sig doesnt do that at all. the shift is actually quite minimal.

I'm glad that someone was able to get my pics to post in thumbnails, because I wasn't. ;)

Anyway, I'm pretty sure there is something wrong with my DS; I don't think anyone else has glow that bad, and most people have reported getting a polarizer, which I evidently did not.

This isn't an "older" IPS screen; it's an H-IPS panel, the same one in the NEC, in fact.
 
I've owned, TN, VA, IPS

Short answer: IPS was the best in all categories including Gaming, and color reproduction. Although on some IPS panels one side of the screen looks a bit darker than the other side, but on most colors you can't notice it.

We have a bunch of the older S-IPS screen HP 2065 screens here at work. While you can see a purple tint on black at an angle, nothing looks remotely as bad as those images. That looks like an aberration to me.

Sitting behind behind the 2065 and using it, you can move all over the place and the image is rock stable. Sitting behind my PVA Dell 2007fp and you couldn't move at all or different parts of the image would start shifting. These screens are the same vintage and size (and nearly identical specs), the difference in using them is night and day.

After the 2007fp, I got a cheap TN screen that is much more usable. There are some weird effects of using a *VA in person that you just don't get in a picture or even a movie (Do to gamma shift between eyes, making weird unpleasant 3d effect).

The only new H-IPS screen I have seen is on the new iMac 24" it looked great as all the older ones I have seen, except it didn't have the purple tint on blacks at an angle. There was no weird glow.

In that case, I changed the picture above to show a different example.
 
For me, the problem with PVA screens is the black crush. Looking straight on at pictures, especially darker areas, the detail is lost. But even more disturbing is my left and right eye see different images and I get a sort of 3d effect that is a bit uncomfortable. It's kind of like the feeling you get when you try to view a TN screen with your head turned 90 degrees to one side. This black crush also forces me to be about 30 degrees off axis to see darker tones. But then there is slight color shift as well when you move slightly left and right and up and down too.

For color critical work I wouldn't trust PVA as I don't know which head position gives me accurate colors, or to be more accurate, which eye pointing at which part of the picture is giving the accurate color. This is at least the case for the 1905FP I use at work which is calibrated and profiled. Trying to match a color from a picture I took to a sample in front of me was impossible because that color solely depends on the exact eyeball to pixel viewing angle. Different eyeball = different color.

For color critical work s-ips only. If color doesn't matter, then there are pros and cons for both that can help you decide.

Huh? The gamma shift on my *VA screen is definitely not bad enough to make the image look different from each eye lol. I have to move my head a good bit to the side to see the shift.

*EDIT*

*And black crush depends on the monitor. Some *VA panels don't have much black crush to begin with, and proper calibration can remove all black crush from them.*

Lenovo L220X HAS colorshift typical for *VA panels.
From an angle black becomes gray, red becomes yellow, more picture details appear.

BY NO MEANS it matches the viewing angles of IPS. Blue sea turns green, blue sky turns gray, the girl gets 10 years older.
 
I just spent some time comparing my LG L246WP to the 23" Apple Cinema Display and if I had to choose I think I would go for the LG, but it's close. The colors of the Apple didn't shift as much as the LG, but the white glow made blacks and very dark shades look worse on the Apple. The Apple also had more "sparkle" than the LG and didn't have as good out-of-box calibration as the LG.

You don't notice it, doesn't mean others don't. A lot of people insist *VA has perfect viewing angles and no tone shift, no lag etc... It doesn't mean these things don't exist, it just means you don't notice them. I do.

I have a TN screen now and is more stable in the horizontal direction. I can see the vertical shift, but it doesn't bother me. Flip the monitor 90 degrees into portrait mode and I get that fake 3d effect again and can't stand using it. This is clearly to do with different view to each eye do to tone/gamma shifting. With *VA I get it all the time and can't stand using *VA for any purpose unless as a TV from 6ft away or more (reduces viewing angle problems).

Bottom line for everyone: at some point you have to try/buy the screen that works for you. You win if you are not very picky, as you can buy a much cheaper VA or TN screen.

If you are really picky you need something like an NEC 2490 and that cost 2x-3x the price of other 24" panels.

Objectively: *VA screens gamma shift the most in the horizontal direction. TN panels shift the most in the vertical direction. IPS panels are the most stable.

Subjectively: to some people it doesn't matter at all, to some others they can't stand TN panels, to others they cant stand *VA panels, some can stand neither TN nor *VA...

In the end, it is not the objective behavior of the panel that matters to the individual, but the individuals subjective response to it, and unless you are extremely suggestible, no one can tell you what your subjective response will be, you need to discover that for yourself.

Calibration does not remove black crush/colorshift from *VA - this paragraph is tought in elementary school.

*EDIT*

I didn't say it removes color shift genius, but yes it can remove *a small amount of black crush if the monitor doesn't have much to begin with*. If all of the numbers on this page (http://www.lagom.nl/lcd-test/black.php) are not distinguishable from each other and the background then you have black crush. However, *depending on how bad the black crush is, it may be possible* to calibrate a *VA panel so that all shades on that page are distinguishable from each other and the background, thus removing black crush. When black crush is removed, images still appear lighter when viewed from an angle, but more detail does not appear.

That's an opinion that could change from person to person. It could also depend on the *VA panel you're comparing it to. However, I will say that IPS panels without any glow are hands down the best, and no *VA screen will ever approach them.

Calibration does not remove black crush.
Black crush is a part of *VA technology. Calibration does not change technology. We cannot wash and wax a Corolla to convert it into a Lexus.

You just don't understand what you are talking about.
With so-called calibration you can play with cubes on lagom. Nothing more. You can pull your cubes out of darkness making everything grayish, spoiling all the rest. Nothing about real colors or the picture quality in the whole.
If you don't understand that 2x2=4, nobody can help you.

the samsung 275T+ (pva) looks better to me than the doublesight ds-263n (ips) i just got a couple days ago. this is because of the annoying white glow that my ds-263n has, as well as much less contrast

Lol those videos and images are beautiful, but they don't help your argument. The black crush effect in those images is exactly what I fixed by calibrating my monitor (note that gamma shift is a totally different concept which cannot be fixed through calibration). Like I said, when I move to the side, the image gets brighter or more washed out, but it does not show more detail, implying that there is no black crush. Black crush is when you lose detail in dark areas when moving from the side to directly in front of a *VA screen, is it not? Well, after calibration I don't lose detail. And no, it didn't make everything grayish. However, you are correct in saying calibration does not help gamma shift. When I move to the side, I don't get any more detail, but everything does become somewhat washed out.

If you don't think I understand what black crush is then why don't you thoroughly explain it instead of just posting brainless comments like these:

Could be worse on some *VA screens than others, but I definitely notice black crush on mine. As to the gamma shift picture in an earlier post, I could not get a shift that severe on my setup to make everything pale white

Now on to the calibration, both my VA screens are calibrated using the gretag macbeth eye one display V2 and net the same result. There is still black crush. If you think about the physics of things, it'll make sense that many calibrators would not be able to solve the issue of black crush.

The colorimeter samples the color in an area. The colorimeter sits right against the screen, with the sensor only slightly above the surface of the screen. Well, when it samples an area, only the pixels directly perpendicular to the sensor pixel would show the black crush effect. However, because the sensor is so close, all the neighboring pixels would be at an extreme angle already and be lighting up more than the pixels directly in front of it. Since the sensor averages, the few perpendicular pixels would represent only a small amount of the average, with the other pixels around providing more of the light. Thus, on average the black crush could not be calibrated for. I guess if there were a colorimeter that only took light coming at a perpendicular angle, this could be resolved. The monoco optix pro XR mentions something about light tunnels, maybe it is to help those with PVA monitors calibrate so straight on viewing becomes more accurate than with other colorimeters. But it is pretty apparent the eye one display V2 does not resolve the black crush issue.

I have calibrated 2-TN, 2-PVA, and 1-IPS monitor using the same colorimeter to the exact same settings, and it is clear from straight on that the PVA monitors have black crush. Both the TN and IPS panels show the darker shades fine, on the PVAs it is just a dark blob until you move your head off center. At the right viewing angle on the TN and PVA, you can get it to look close to the IPS monitor in terms of detail and color tone, however that narrow position (which only reflects one part of the screen being accurate) is a chore to find.
 
Now we are arguing semantics. I'll agree "black crush" is not the best term, but some reason is the one that caught on to try to describe the phenomena. I called it washout when I got my first *VA. The reason why black crush stuck is the default calibration of most *VA panels tends to have black quite crushed when looked at straight on, with more tones becoming visible as you move your position/viewing angle. Since most people don't calibrate the name tended to stick. Most *VA panels will show crushed dark end when viewing angle is perpendicular.

Now it might be possible to calibrate to the point that you could see all shades when viewing perpendicular, but I expect the monitor would look quite awful and washed out when not viewing perpendicular.

It is the tone shift that drives me nuts. I don't care if you call it washout, black crush or Shirley. It sucks by any name.
 
I should revise my statement. Maybe you can't always fix black crush through calibration. It must depend on how bad it is to begin with. The LG L246WP doesn't have much black crush to begin with, so maybe that's why I was able to easily get rid of what little there was with calibration.

Here's a couple quotes from reviews of the L246WP:

From HDTV Reviews:
"a large amount of detail showed up in darker areas of our test videos. We had no complaints with the black or white levels"

From Generation X-Tech:
"It was able to differentiate between subtly different dark and light tones"
 
No.

(Maybe rule out TN if you want, because of lack of 8 bit color. Otherwise, I'd take each display on its own merits and make sure you've got a good return policy. Buying an LCD is a lot harder than it should be...)

Exactly an issue I have with *VA. It is something that no simple picture can show you because you need both eyes active with the panels strange angular tone shift to get this effect. That is why I don't think pictures generally do justice to how bad VA shift really can be if you are sensitive to it.

This is why I find using *VA intolerable while I can tolerate TN panels which have even more shift but in the vertical direction.

My TN panel has a swivel stand, to swing 90 degrees into portrait mode and immediately I can't stand using it, just like *VA. The shift may be worse on a TN panel, but it is in a much more tolerable direction. Now if I were a cyclops I would prefer the *VA panels to TN as the nasty stereo vision phony 3d effect would not longer bother me. But IPS would still be better.


I will say again: some of this always depends on individual reactions. No VA panel would be better for me than even the worse IPS panel, because I can't tolerate VA. YMMV.

...ASV panels by Sharp is the easiest on the eyes...
Click to expand...

The Sharp I had (GP3U) seemed fine on the eyes. Text was slightly less clear due to the multi-pixel technology. And it did have a noticeable color shift when viewing a white page, as there was more yellowing of the image than I've seen on other displays...
 
Snowdog, I know the "3D effect" you're talking about, but I'm not so sure it's caused by your eyes seeing different gamma tones. I'll test when I get home to see if the effect goes away when I close one eye, but I'm pretty sure it doesn't. Also, I think the effect can be reduced through calibration. I remember thinking it was noticeable before calibration, but I haven't noticed it since.
 
3d effect most certainly did go away when I closed one eye. That is also why it was only bothersome on the TN in portrait mode. Anyway I am tired with arguing about this, let's just say *VA won't work for me. YMMV.

In the end everyone has to see what monitor works for them as we all have different tolerance levels for the various issues with LCDs (lags, smearing, viewing angle issue, inverse ghosting from overdrive, color banding, excess brightness, poor blacks etc....).

My best advice for anyone who doesn't know what works for them. Buy where you get a good return policy, because what looked good in the store may drive you nuts 20 minutes after getting home.

The Lenovo L220X does not suffer the problems that typical S-PVA panels have. It has no color shift even at extreme angles: http://forums.lenovo.com/lnv/board/...ion&thread.id=2&view=by_date_ascending&page=1

In fact this panel matches the viewing angle of S-IPS screens: http://www.notebookreview.com/default.asp?newsID=4241

You can't tell from those pix, which are exhibiting extreme gama shift, and to be expected from that extreme of an angle.

We need pix of head on dark detailed screen shot (pic with varying dark colors) and one at a angle of about 20 degrees off center. I still don't think people understand waht is happening with the shift/ crush, it's there even viewed head on, as the side are bieng viewed at an angle. You don't need to view the screen from the side to notice it.

Now if Smasung has somehow emulated the crystal structure of that panel to match Sharps ASV, the crush would be reduced and not as apparent. The only way to "calibrate" the crush away, is to bring the black point out of the crush zone, thus defeating the purpose of owning a VA panel.
