gaming at 4K = the future?

The "best" interface we have right now is DP1.2. I'll quote what I've written before on bandwidth / refresh limitations for high-res screens:

Displayport 1.2, with a quad-lane interface, can manage ~17Gb/s. That's enough for 120Hz at 2560×1600, or around 60Hz at "4k" resolution. To get 120Hz at "4k" you would need, at least, two DP1.2 connectors. The GPU would need to output (say) alternate frames from each displayport adaptor. Either that, or output half the image from one port and half from the other.

New standards are always on the horizon, but using an existing displayport interface, the obvious way to increase bandwidth is to use more multiple displayport adaptors. For 4k at 120Hz you would need at least two DP1.2 adaptors.*

Note that HDMI 1.4 (the latest and highest bandwidth spec of HDMI) has around half the bandwidth of DP1.2, and so would be capable of only around 30Hz on a 4k screen.

Indeed. Which is what i was trying to point out. The screens are more than capable but the interface sucks at the moment unless you go DisplayPort 1.2 which as the info says, requires 2 to get 120Hz. We're only interested at least 60Hz, unless you want 3D.
When its actually affordable, before mainstream, i'm sure they'll of got a suitable interface sorted out. We have at least half a decade yet..

It'll be at least 10 years before 4k TVs are available in the mainstream, another 5-10 before they are common.

4K terrestial tv will be about 30 years off... BBC and all the rest will never transmit in 4K, they cant even manage 1080p yet

i disagree that a single card pc can handle 4k, because mine can only just handle Borderlands 2 at 1080p maxed out, i would not touch a 4k tv for gaming with my present rig, because it would deffo need upgrading.

borderlands 2 only really runs fast if you turn off PhysX plus downgrade to 4X.........4K, no way it would deffo crash

We'll see, there's no plans to start broadcast of 4k content at all at the moment, we're still transitioning over to digital and HD after years.

I wouldn't let 100" £20k specialist niche screens get you hopes up that in 5 years we will be anywhere near considering 4k screens as being mainstream.

My assessment is based on two factors. First, the existing 3D technology has not caught on in quite the way manufacturers were hoping and a lot of people are now waiting for 4k to upgrade their current set. Second, an advantage of 4k screens is that they can display passive 3D at 1080p. This means all 4k displays can be made 3D by default without increasing material costs, and the people who want 3D but are being put off by the need for expensive active glasses will lose their chief demotivator.

These factors combined make it sensible for manufacturers to shorten the upgrade lifecycle on the current technology. The sooner the next generation appears, the less likely it is that the 3D bubble will have burst and the more 3D upgraders they will get early on when 4k TVs still command premium prices. Also, by shifting focus to 4k now they will save development costs for new 3D screens that might not sell if the bubble does burst, instead spending the money on a technology that will only become more relevant as time goes by.
 
3D TV was never going to suceed anyway, simply because it failed 3 times in the past, so why release 3D yet again when the only major difference from 20 years ago is HD !!!!! crazy isn't it

1080p would be far better in the future if they could improve the refresh rate/ engine process speed etc, because the sharpness/ pixell size is perfect already.

it's the movement that still looks jerky, maybe it's my old tv, plus i keep seeing flickering etc
 
So what speed connection will you need to stream 4k over the internet?

Isnt that where everything is supposed to go, online streaming and all that. It wont be mainstream till our internets can handle it.

4G should be able to do it

My work wifi gets 30mb/sec download and 4k samples on youtube steam ok

You raise a valid point.

IP TV, screw all these other interfaces.
4K can stream easy if you have a fibre connection, but it does depend on codecs and also the sound quality/resolution and the amount of channels.
