TN vs IPS vs MVA vs PVA vs S-PVA

[tuteja1986]

Which Technology do you perfer ?

Edit :

I wish I knew the differences...are there any articles you could link so I can learn?

 

[Gamingphreek]

He is referring to different types of TFT LCD displays.

I don't quite know why he is asking this. Just looking at an LCD without specs 99% of the people out there are not going to be able to tell the difference. In fact, I don't even believe which technology used is listed in the specification sheet. TN is the most common....I don't know if I care or prefer that. S-PVA IIRC has the most promise, but never really beat out TN.

TN is most common. That common that I doubt I have used anything but it.

Excuse me, thats what I meant. I don't know why I wrote MVA.

Yeah I knew that but I just don't know what the differences are. I've just heard that TN is not as good as the rest. And I think I read that IPS is the best for picture quality. Don't know if that's right.

 

[Gamingphreek]

Well they all have their flaws. Technically PVA and S-PVA have the greatest upside but simply have not caught on yet; and probably never will. TN, the most common BY FAR, is limited to lower color reproduction (6-bit compared to 8-bit) and a lower Contrast Ratio.

I don't remember much about IPS or MVA except that IIRC IPS generally has better color reproduction and a slower (~30-50ms) response time.

TN are lower quality and therefore will be cheaper. Supposedly what they lack in color, they make up in speed (low response times).

IPS do have better color, but higher response time, though I think we're getting to a point where they're becoming acceptable for gamers.

And as far as PVA, I'm not as sure. Supposedly their strong point is contrast ratios, but I'm not as keen with them.

I'll be in the market this winter, and will probably limit myself to IPS or PVA.

EDIT: Here's a good explanation of each type

well i might be wrong about this, since i'm basing this off some vague memory, so dont take this as gospel

TN = the cheapest panel. worst color(6bit) and bad viewing angles but fastest lat

PVA = really good color(8bit) but higher lat times.. a little more expensive than TN. i think these panels are made by samsung?

IPS = good color(8bit), good viewing angles, kinda fast lat (but slower than TN) also the most expensive

MVA = no idea



edit: if money was no object, i'd go IPS

20WMGX2 uses a S-IPS panel i believe

OK guys...Someone has to put you out of your misery :disgust:

TFT-LCD: A brief introduction

TFT-LCD: I want to learn more

 

[TheRyuu]

IPS should win outright in this one.
The S-IPS panel in the NEC is probably the best that's made.

P-MVA in my VX2025wm is also good but not as good as the IPS.

I dont even know why this is up for debate.

IPS is by far the most capable LCD technology. It offers the best viewing angles, the most accurate color reproduction and it is no where near as slow as gamingphreak implied.

The S-IPS panel some (like me) Dell 2007wfp owners were lucky enough to get offers a response time of 8ms gray to gray and probably has a max of 10-16ms response time for all transitions. This can be confirmed at the LG/Philips website. The S-IPS panel in question is the LM201W01.

The NEC 20WMGX2 uses the AS-IPS which is also manufactured by LG/Philips and is the best panel available. It offers better response time <10ms for all transitions and offers a much higher contrast ratio.

My list goes like this:
IPS
|
MVA
|
|
|
|
|
PVA/TN (tie)

TNs have by far the worst color reproduction and viewing angles. At 22" they also have a gut wrenching pixel pitch. TN's only saving grace is that it is fast, but what's the point when you're not even getting accurate colors?

It's also worth mentioning that the panel type is not the only factor in getting a quality LCD. Companies can offer seemingly good panels, but manage to make the worst LCD ever, think S-PVA Dell 2007wfp.

Interesting you mention the Dell S-PVA. I was no monitor maven when I ordered my Dell 2007WFP but as soon as I lit it up I could tell it was grubby and could not believe this was the panel getting rave reviews.

I went online and that's when I found out Dell was switching panels. I knew I had a crapper without checking model numbers (which I did latter anyway and was right). MAny people complain about having a bad view from an angle - but Dell's S-PVA actually manages to give you the crap view when you look head on. A sidways view actually ADDS details. Once you see this effect in action you won't mistake it .

Here is pic with a photo on a Dell S-PVA 2007WFP. The top photo is straight on and the bottom is the same photo at an angle:

I know not all S-PVA is bad and the way they are lit from back etc are important but the Dell is not so hot. Of course some people dont like the purple with the S-IPS but that shows up sideways and not head on.

After looking around and visiting freinds houses s well as my own adventures I generally would prefer a S-IPS although for video and such I could see an S-PVA or S-MVA being quite nice if its built right.

We'll have a new kid in town soon,A-MVA from AU Optronics,link and link ,so battle for best type of panel is still ongoing as always.

AU Optronics Corp. ("AUO" or the "Company") (TAIEX: 2409; NYSE: AUO) is scheduled to participate in the FPD International 2006 exhibition in Yokohama, Japan from October 18th to October 20th, introducing its latest products and technologies. AUO will be showcasing its latest TFT-LCD innovations, including Advanced MVA (AMVA) technology with low color washout and super high contrast ratio of 2500:1; HiColor technology with the achievement of high color saturation; AUO Simulated Pulsed Driving (ASPD) technology with the solution of blurred motion problem; and AUO Picture Enhancer (APE) technology featuring natural color images and clear depth of view.

AS-IPS if I could.

 

[CP5670]

IPS should be an obvious choice at the moment, as was explained earlier. Most of the current higher end LCDs use IPS panels of some sort.

i have AS-IPS.

S-PVA is not as bad as TN. but once you go IPS, you never go back.

honestly if you can afford it, get it. monitors last a long time anyway. TN maybe if you are really that sensitive to refresh rate. but i doubt most people are.

 

[keeleysam]

IPS, and I game on them.

 

[Tom33]

So can someone recommend a good IPS LCD ?

19 or 20", NON-Widescreen, less than $500.

Thanks
