E-IPS v AMVA Panel

Which Panel meant to be best E-ISP or AMVA?

bit of a broad question really

depends on uses etc. have a read of this, and determine what is going to suit you more:

I am trying to understand as best as I can. Can I view the E-IPS and AMVA at angle and seeing the images in a good way. I know on TN viewing on Angle is crap so I want to be able to view at angle good like my MacBook pro. If they both are good at viewing at angle that good

From what the internets say, the macbook pro is TN with an LED backlight, a good TN but still TN(6 bit panel not 8 bit). On IPS and VA you should be able to view the picture perfectly fine from pretty much any angle you can see the screen, it will just be a little less bright and squished from your perspective.

My Macbook Pro is a S-IPS i Believe as it one of the earlier version before the LED version came out. I can veiw my screen at any angle without a problem

VA panels are still good from wide angles, but they do show an off-centre contrast shift which is talked about in that article. Many people wont spot this or ever find it a problem, but some people do, which is why they recommend IPS panels. IPS matrices do offer the widest viewing angles

IPS isn't exempt from image deterioration when viewed from an angle; if the technology isnt backed up by an AT-W polarizer, then you will see a white glow.

The perceived effect isn't too dissimilar to the contrast shift seen in AMVA panels. In fact, I'd say it's slightly more intrusive.

the white glow from a wide angle is more of a characteristic you will see from IPs matrices which do have an A-TW polarizer, but yes, you will see this from a wide angle. The contrast shift i mentioned for VA panels is different though, and i was more referring to when you move your line of sight just off-centre, you can detect a shift in the contrast even then. You wont see this on IPS panels, but on VA panels, you can spot this shift by just moving ever so slightly around a central field of view

I found the gamma shift on a S-PVA panel much more noticeable than the white glow on an IPS, especially on this forum and on HardForum where two similar colours are side-by-side - the PVA shift can be seen from dead on, whereas white glow needs an off-angle.

Don't forget black crush as well on a *VA matrix, which you also don't get with an IPS.

I'm not sure "black crush" is intrinsically any worse on *VA panels than *IPS, if by that you mean the inability to resolve subtle differences in blacks and very dark greys (rendering them as an undifferentiated dark "hole" in the image). If anything, I thought *VA panels traditionally had the advantage here, although certain recent IPS models seem to have caught up.

The terminology is confusing, as some people use "black crush" to describe the *VA off-centre contrast shift mentioned earlier, as this can also have the effect of reducing black detail in the area of the screen you're viewing directly head-on.
