no wonder we see so many posts asking what TV to buy, should I buy curved, 4K, etc.

What worries me about curved screen TVs is that they must be a bugger to view off axis. OK the far side of the screen would be easier to see from that armchair in the corner, but the near side of the TV is going to present itself almost edge on! How does that work?

I'm no rocket scientist, but "High Dynamic Range" is just a fancy term for contrast ratio, yes?

As for Samsung and their curved TV screens, they're selling a gimmick and they damn well know it.

I almost feel like getting a salesman at some electronics store plug the supposed benefits of the curve just so I can have a laugh.

Going by CES the new screens will be able to adjust between being a flat screen and curved by the touch of a button, so the best of both worlds. I've found curved gives you that sweet spot where you feel you are more immersed in the movie/game, it's fantastic for gaming after playing with one a shame I can't afford one for myself. There is an interesting article here:

http://www.immersaview.com/resources/why-curved

Some people try and get the same wrap-a-round effect by having three projectors projecting on to a slightly curved wall. The aim being a cinematic feel similar to what theatres and cinemas have been doing for some time.

Another feature is it blocks a lot of the ambient light coming in from the sides, and also reflects ambient light away from the viewer. Less ambient light = blacks appear blacker, colour accuracy improves etc.

Some people mention that they can't be wall mounted, there's only one model that can't be all the rest use the vesa standard. Price is where it falls down, the price is inflated but like anything this will drop over time.

As for phones with curved screens, this is just a gimmick on such a small screen whats the point.

When will I buy? I'd rather have a high end LED projector.

Good point about multi projectors. I bet I am not the only person here who angles their second computer monitor so that it is perpendicular to where I sit. With the big monitors we use now days, it would be daft not to.

Another example is multiple monitor setups on PCs, of all the installs I've done or have seen they are all on a curve/angle. So the new ultrawide slightly curved monitors make sense. It's just natural/comfortable.

The hard part with a TV is getting the curve right so multiple people get the similar viewing experience. Which going by what I read the new gen will have adjustable curves :-)

HDR refers to how an image is processed to make the very bright objects not so bright and very dark objects not so dark; so these pixels fit into a shade of pixel that gives a colour [there are only so many colours a jpg, a video file can store, within a fixed spectrum). once an image is burnt onto bluray i cannot ssee how a TV can recover these details. usually people processing HDR add oddles of colour saturation to top it off.

unless of course in TV HDR refers to making everything more vivid. if that's the case they will turn up the saturation and make badly encoded media very coloured!

or .. umm ... contrast ratio is a good start. but it won't recover any lost dynamic range in the encoding ... and contrast ratio is pretty good already ... and there are only (correct me if wrong) 255 shades of contrast in video encoding and you cannot improve on that however high dynamic a TV's range is. unless it paints its own shades

i hpoe they make 100" TVs cheaper. don't care about the resolution, as long as my Blu ray and Freeview comes in 1080p, 1080p is fine!

agree, I currently run a 1080p projector with a 100" screen would love to have a 100" LCD instead but I think you might start to make out pixels at 1080p so a 4K would be better. Plus they are more likely to make 4K screens at this size as you can already get 84" 4K in NZ.

$$$ ;p considering a decent 50" can be had for $500 on sale, a 100" "technically" is 4 of those ... so ... umm $2,000 ;p

Be it on a 22" CRT or a 80" 4K panel Shortland Street and all reality TV is utter rubbish :p

Here is a crazy notion, lets give peace a chance.

The big difference, of course, is that those multi-monitor PC environments are set up for one person who's quite close, not multiple people a few metres away.

The further you are the less curved the tv needs to be, till a point where it becomes flat. E.g. You don't notice the earth is round but that a soccer ball is round is pretty obvious
