So here is my bother.
My first 2 LCD's were TN after I ditched CRT, I brought without any research, needless to say I was horrified with what I had, horrific viewing angles, trails behind the mouse when moving it, behind text when scrolling etc.
I eventually got a PVA (might have been MVA not sure now). Viewing angles much better, still bad trails when moving mouse etc. tho. But could at least watch stuff in bed (as on a TN it got too distorted).
Then a while after when dell released the brilliant one of a kind 2209wa I thought thats it the future of lcd's is sorted. a e-IPS panel, great near perfect viewing angle, I can stand at quite extreme angles and the picture is about the same as been right in front of it. The lag when objects mvoe on the screen is gone. So it was near CRT performance but as a LCD. However it seems things have gone backwards since.
So about 2 years after I got the 2209wa I got a 2nd e-IPS, the 2209wa was discontunued by dell very quickly after launch, no real obvious reason why as it sold very well, so this 2nd monitor was a different one, but also due that I needed hdmi input which the 2209wa doesnt have. This 2nd e-IPS is edge LCD backlit vs the traditional baclight the 2209wa has. I also think it has a lower spec 6bit panel vs the 8bit in the 2209wa. I was expecting possibly increased lag, and lower colour accuracy. I wasnt expect the much worse vertical viewing angles. When standing up on the new monitor a dim bar appears and moves depending on how much I am standing up, it dissapears funny enough when its an extreme angle but is viewable sort of in all the in between angles, it also has noticeble lag, eg. scrolling text has issues. It does have superior contrast ratio due to LED backlighting but thats the only improvement. So a 2 year newer monitor using same panel type is for the most part inferior.
On to tv's. Samsung seem the most favoured brand by a lot of people (I know not by everyone), I got a samsung lcd tv, my first lcd tc, about 4-5 months ago. It does have a samsung panel not an outsourced one. I checked on the service menu. Now after calibrating the tv, taking it out of the demo settings, it looks great but have to view it bang on in front of it, which I do most of the time thankfully but obviously is instances I may get up to do something and then look at the tv eg. whilst standing up. This is the current year model and VA screen but the viewing angle is almost 0. Is noticeable severe reduction of contrast ratio off angle both sideways and height wise. My sister's old samsung tv had the same problem but much less severe and it only had it for height not sideways. It was the same spec tv but the year's previous model and the same panel type, what was the difference? mine has edge led backlighting hers was the traditional backlight.
Now she has a newer samsung tv, a high end model, the panel isnt a samsung panel, its one of the supposedbly inferior panels that samsung outsources, it is LED edge backlit. However the viewing angle is very good, not as good as my 2209wa monitor but its leagues apart from my tv and her old one.
I do get the impression viewing angle isnt considered important by LCD manufacturers. As the 2209wa seems an oddity not something that became a trend, and my theory as to why the 2209wa got canned was it was "too good" hurting sales of premium IPS panels. I would like to be in a situation eg. where I can be confident every e-IPs has the same viewing angle but it seems even with the same viewing type there is huge variances.
I am also curious if manufacturers deliberatly hinder viewing angles on lower priced products that use tech thats capable of good viewing angles.
