IPS Information
- Thread starter icor1031
- Start date
Mainly IPS glow, except for ones with ATW polarizers, which I don't think are being made any more. If you look at an IPS screen at an angle on a black or dark screen (it's also more noticeable in a dark room) then the screen can appear blue/purple, gold/orange or silver i.e. this:http://www.youtube.com/watch?v=fPlx42Gj1Nw
IPS screens generally have poorer black levels and contrast ratios, about on par with TN panels, maybe a bit better with newer models.
I should add that I think traditionally, IPS monitors have slow response rates and/or input lag, but newer models such as the HP ZR24w, Dell U2410 and particularly the Dell U2311H are fast enough for the vast majority of gamers.

IPS have really poor viewing angles when viewing dark content. This is apparently fixed by a A-TW filter but no monitors that are on sale today have that.
Compared to TN IPS have a bit slower response time, although this isn't really an issue in my opinion (and I believe most that have tried it would agree).
IPS panels usually has the most agressive AG-coating of the three panels. This results in a somewhat sparkling surface (primarily on white surfaces) and can cause eye-strain unless you learn to cope with it (it can take some time getting used to but most won't be distracted at all after a few weeks of use).
IPS blocks more light than any other panel-type, this means you need a brighter backlight and a brighter backlight (which is also a huge part of the price for IPS) means that it draws more power which of course means it also gets hotter. My opinion is that this only really comes into play when getting to really large displays such as 30". But this is of course a big drawback when it comes to laptops which is probably one of the main reasons (other than price) for why IPS is so rare among laptops.
This post of course will seem a bit anti-IPS, but you only asked for the cons and downfalls
I still believe that IPS much better than TN and marginally better than *VA (although depending on the usage the difference between *VA and IPS is negligible (my opinion) and personal preferences can tilt the favor in any direction).

There are no real cons of IPS over TN. However, over the latest VA, the benefits and negatives must be considered.
The main benefit of IPS is its stable image, which benefits everything, but particularly means that IPS has no weakness in photographic applications. The main flaw of IPS is the contrast ratio compared to 3000:1 VA: IPS lacks the necessary purity in dark tones to deliver a reference result for films and games.
It is important to note that as of Q2 2010 IPS has 94% market share of the wide viewing angle monitor market according to LG Display citing DisplaySearch. Almost all partners except for Eizo are using LG IPS exclusively now.
3000:1 C-PVA and A-MVA panels can deliver the best result for multimedia, but some of their pixel response transitions are very slow, leading to trailing. Their narrow viewing angle effect is the main limitation; but even theoretically second place to IPS, PVA monitors are regarded as "acceptable tools" for colour work according to Quato. I would agree with this. An IPS monitor of lesser quality would not match a quality PVA monitor for colour work even considering gamma shift.

Okay, I'm going to try to redirect this thread now .. And thanks for the responses.
Currently I have an LN40B550, samsung *va (I believe) with 40" and 1920x1080. Correct me if I am wrong, but it seems like there are 'lines' through the image, I assume because of the very low PPI? It just seems like a dull image. My TN that I'm on now doesn't appear to do this.
However, the colors are pretty accurate, it gives a much more pure white than does my TN, and obviously - the blacks are far better.
This TN, an Asus 25.5", washes out a lot of color..
Mostly, I spend my time doing research/reading, etc. but I game a moderate amount too. I want something with a sharp image, and something comfortable to look at. This particular 26" I'm on, is not. As I said, the colors are washed out - it's very white, even though a dull white, it's hard to distinguish many things.
What should I get???
Note, I'll be using 3 of whatever monitor I get, esp. in games.

Hmm, a 40" is bound to show a screen door effect when used as a PC monitor. I think you're spot on - the PPI is extremely low for what you want to use it to do.
I have never seen a TV to be anywhere near close to ITU-709, which has the same color primaries as sRGB, no matter what you do. But it sounds like the contrast of the TV is higher than the 26" monitor, and that the brightness is also higher (i.e. the impression of pure whites).
As in what to get, it's a hard question. Do you notice input lag on the TV? Some/most S-PVA based monitors have high input lags, which some find to be too much for FPS types of games.
Do you know the model number of the Asus you have?

No lag issues.
VW226H for ASUS, but I hate it. On the black/white chart things, if I manually calibrate so I can see blacks - then ALL the white blocks look the same. If I can see white blocks, then ALL the blacks look the same...
this: http://www.imaging-resource.com/ARTS/MONCAL/CALIBRATE.HTM
...
also, here's two pix. Same settings (dslr), very close to same distance from monitor, each time.
I'm sure you can guess which is the VA

Aha!
What do you think, have I found the answer to my dilemma?
http://cgi.ebay.com/Samsung-F2380-2...6180?pt=Computer_Monitors&hash=item43a2f64074
c-pva(?) panel, and I assume it'll be sharp like a normal lcd monitor, right?

The base panel has a good columnar pixel structure like IPS. The F2380 itself has very poor image performance and needs hardware correction. Some people have said on this forum that the F2380MX has improved factory settings, but there isn't any evidence.
The Eizo EV2333W which uses the same panel has exceptional performance from the factory.

Cool story bro.
