I saw one of these in JB Hifi the other day. It was an UHDTV running one of those UHD demo loops.

My initial impression was that it's a gimmick. It didn't appear to add anything to the viewing experience for me.

What do you geeks think of them?

I agree with you that 4K is money down the toilet, as there is no native content in NZ. This is throwing something different into the equation with the curvy thingymabob.

I suppose it will make you more cross-eyed and have hallucinations.

Yeah, prolly will. I can't watch 3D movies at the cinema. My vision is kinda messed up already and that 3D gives me real eyestrain.

I'm going to hang out for when you can get an operation and have a USB port surgically implanted into your scull and wired directly into your visual cortex. The ULTIMATE viewing experience. tongue-out

why does everyone think you need 4k content to benifit from a 4k screen?

An upscaling 4k TV would be a nice luxury item.

A concave TV is a silly luxury item IMHO unless you are a geek and don't have friends visiting who want to watch the TV with you.  Why else would you put up with having one 'sweet spot' for viewing?

Perhaps if they wrap one around 180 degrees it might be awesome for use for a flight simulator or racing car simulator.  :)

I would see the concave part of the TV only being useful in smaller rooms, otherwise it's just a proof-of-concept gimmick to show off Samsung's flexible screen technology.

4k on the other hand is a very nice upgrade though the TV market is still expensive. I purchased a 28 inch 4k computer monitor for $900 and it was a very good purchase indeed, especially with Samsung's split screen feature that allows two computer inputs to be displayed at the same time.

4k is worth it but just a little on the expensive side at the moment. As was mentioned, even though there is no native 4k broadcasts, upscale content still looks great and games can also be displayed at 4k (just don't expect to be running the quality at ultra).

+1 regarding the sweet spot but I recall that earlier in the year at CES in Las Vegas, both Samsung and LG showed 4K tellys that could be remotely changed from flat to curved and back again. However these were only proof of concept and not actually on the market yet.

IMO curved is still a gimmick though but upscaling to 4K would be very nice as you say.

I agree with what's already been  said the curved screen would only be ideal in a smaller room due to a lesser viewing angle. As for 4k tv's they do look great but are horribly overpriced and although there is content out there it's not easy to find somewhere that stocks it so your best bet on that would be to buy online. Probably find that a lot of the available content is also upscaled as I couldn't imagine a lot of film makers naturally filming in this way.

Full HD is fine for current TV's, but the larger TV's get the higher resolution/smaller pixels of 4k and 8k is needed to maintain the clarity in the picture. Who wants to see pixels?

The winning blow with 4k and higher is with passive 3D. Which is a far more comfortable 3D compared to active, and the glasses can be had for a $1.

With passive 3d loosing half the vertical resolution under Full HD it is very noticable when compared to active 3D. However under 4k or higher this isn't an issue any longer, your still loose the half the vertical resolution but under 4k it doesn't matter because of the higher resolution.

Full HD passive 3d - 1,920x540 per eye
4k passive 3d - 3,840x1,080 per eye

With Full hd passive 3d you end up with a scanline effect, which is completely gone under 4k.

Up-scaling to 4k is really a gimmick, as with up-scaling DVD SD content to full hd.

I would buy the Sony4k ultra hd media player if I was to get a 4k TV. Netflix is moving into 4k streaming too, so content is coming a long. Of course 8k TV's are being released...

The concave TV is only worth while if it's 100" or more, then it gives a "going to the movies" like experience. On the average size TV 40-55" it's not needed.

As for price if you can get a 50" 4k TV for $2000 that's a bargain, not really that expensive. Plus if you wait the price will drop further when 8k becomes the norm.

The guide below is quite good...

4K would be good in an apartment with smaller lounges thus shorter viewing distances. We are currently looking to move from the burbs into a central city apartment and may sell our 65" Panisonic and get a 4K to replace it.

4K content is not that far away with fibre able to carry 4K and over without issue.

If there was 4k when I was buying the bedroom tv in could have gone for a bigger size. As it is 55" is too big as I can see the pixels on some colours.

I was really intending for this thread to be about these new-fangled curved screens, not the pros and cons of 4K resolution. Anyhoo... smile

Well if the screen is curved I'm not getting it. That only makes sense when a screen is big enough to be your complete field of view and there isn't the content for that size screen available.
