Son, all we get is edge. The few models that come with an actual, usable array cost north of $1500.
Also, it's not the LED's that are expensive; it's the electronics involved in controlling them.
LEDs and controlling chips cost cents. It's only low quantity single units that you want to buy cost whole $/EUR. In bulk these things are dirt cheap especially compared to the price of monitors. Sure the LED cost ads up when you use 1000 of them and they are of decent quality but I highly doubt it's suddenly $500 for LED backlight array as current crazy pricing would have you believe. Or that the processor cost $500 as well.

For that reason, I was looking into VA panels... less than .10 nits black level when brightness is 120 nits or less. My current calibrated black level is like .17 nits... best is .14, but screen is way too dark. I see some VA panels go all the way bellow .05 nits. Most of my use is in a dark room... like pitch black when watching movies.
Anyways, for those that have IPS and VA, do you notice a lot of color shift or anything really "bad" like a lot of gamma shifting with viewing angles between the two?
Since I'm still sticking with SDR, the only real improvement for me would be black levels, contrast ratio, aspect ratio, resolution.
Anyone have a 1080p 34" ultra-wide? I might get one of those if it's not too blurry, but I'd prefer a 1440p.
For those who went from IPS to VA and back?
Roughly black level, contrast:
TN 0.3, 700:1
IPS 0.2, 1400:1
VA 0.1, 2800:1
It's not a big difference between IPS and VA black level and contrast, 2x is noticeable yes but nothing impressive. If they would use glow removing filter on monitor sized panels then IPS would be king, but with the glow most people get annoyed that corners have lower contrast.
Local dimming is the way to go but those are rare, often limited in number of zones and speed of control.
Yes I notice plenty bad on VA compared to IPS
Especially at an angle, on sides of monitor when using it. VA has poor color viewing angles, often poor black viewing angles and poor glow, Samsung HG70 tends to have a little better color viewing angles but awful black and glow, AUO VA 31.5" 1440p 144Hz has worse color viewing angles but better black and minimal glow. HG70 comes with local dimming 8 zones, limited but nice to have anyway, curved and that is a big no no.
Almost all VA smear blacks, badly, only some VA TVs may actually have good enough panel and OD according to rtings that they may not smear blacks.
The shift of image on VA occurs in all directions, circular where as on TN it's in 1 direction, this is mostly for the blacks viewing angles. With most VA you get a small perfect looking center image but the rest is way too different and it gets annoying as you tiny bit move this perfect center follows you on screen. IPS doesn't have infinite viewing angles either but they are much better and this issue of center following your vision is minimized.
1080p is to be avoided nowadays really, especially ultrawide.
You are missing 1 important difference: response times, VA is often terribly slow with out of blacks transitions and this is noticeable even in movies, browsing web, ... for me it's unusably slow because it's in the range of 20ms+, often around 40ms.
If you want to see it side by side I made these comparisons:
On VA you get this smearing, ghosting, colored trails, etc. It really is visible when watching movies, web, games, ...
On a 24fps movie played back on 144Hz monitor and recorded at 60fps it takes 3 frames for the ghosting/smearing to go away, that's 50ms and about same as 1 movie frame 1/24= 41.67ms. It is really that slow, 27" HG70 Samsung VA 40-50ms for out of blacks transitions
Also HG70 Samsung strobing has crap ton of crosstalk making it unusable. Otherwise yes strobing is great sadly only very very few implementations are calibrated or adjustable enough to be usable and not have crosstalk. Samsung blew it big time, they even use the local dimming zones with it but still could not be bothered to minimize crosstalk and you get a lot of double images especially middle, bottom of screen and when transition times are slow.
If someone thinks their VA doesn't smear... drag this in game screenshot around your screen:
