Curved TVs Nothing But a Gimmick 261
Lucas123 (935744) writes "Currently, the hottest trend from TV manufacturers is to offer curved panels, but analysts say it's nothing more than a ploy to pander to consumers who want the latest, coolest-looking tech in their home. In the end, the TVs don't offer better picture quality. In fact, they offer a degraded view to anyone sitting off center. Samsung and LG claim that the curve provides a cinema-like experience by offering a more balanced and uniform view so that the edges of the set don't appear further away than the middle. Paul Gray, director of European TV Research for DisplaySearch, said those claims are nothing by pseudo-science. "Curved screens are a gimmick, much along the same lines as 3D TVs are," said Paul O'Donovan, Gartner's principal analyst for consumer electronics research."

The odd bit is at the end of TFS where they say that curved TVs are a gimmick like 3D TVs. There is a big difference, 3D TVs actually give an appearance of 3D when viewing 3D content, (all the brain-and-eye confusing tricks and deception notwithstanding). Every reasonably normal sighted person can see the 3D effect, most just don't think its worth the price (or the headaches).
Curved TVs on the other hand provide a picture that is indistinguishable from normal flat screens, EVEN when you see them side by side in the store.

I don't own a curved TV, nor am I interested in defending the concept, but one thing I do notice with flat TVs is that even matte displays are prone to reflecting at least some fixed outside light source to the viewer. I can't help but wonder if a curved screen would reduce this.
I have a window that reflects off of a matte display and is annoyingly visible on the screen during the day. The only way to get rid of it is to either put a heavy blanket over it or to turn the tv in a very uncomfortable angle.

If you have a glossy flat TV, then there will be one particular angle where light hitting will reflect right at you and annoy the crap out of you. For a curved TV, there the light will reflect off different parts of the screen for a wider range of angles, thus annoying you even more.

The whole reason why they went with 4k instead of 2160p for the name is because 4k is shorter, easier to say and looks like it is bigger than 2160p.
It's also a more accurate name in that horizontal resolution doesn't vary with a movie's aspect ratio. A "1080p" movie could be 1920x1080 (16:9) or ~1920x800 (21:9) or any other vertical resolution. The 1920 ("2k") is the real constant. I think the usage of lines was a holdover from the days of analog TV when vertical resolution was discrete but horizontal was continuous.

Then why are the screens in a real-life cinema flat?
The answer, of course is that the camera (either film or digital) uses a flat sensor. Taking a picture with a flat sensor, and then displaying it on a curved screen, is just distorting the image. So the consumer thinks they're cool - but in reality they are watching an inferior picture.
Re: (Score:2)

As TFA points out, only one person in the room would get an optimal view anyway.
Finally, if the whole problem is just a bit of geometric distortion, couldn't it be mostly fixed by performing the opposite transform on the image before displaying? That would allow you to optimize for your actual viewing position and come up with a happy average for everyone in the room, or turn it off.

When you watch a perfectly flat TV screen, Soneira explained, the corners of the screen are farther away than the center so they appear smaller.

In a theater, the screen covers a much larger percentage of your field of vision, and the difference in distance to the center vs the edges can easily be several feet if the screen is flat. This is enough to be noticeable. In the living room, the difference will be millimeters, and you'd need a ruler to detect it.
