Does this projector support high frame rates in either 2K or 4K, i.e. 48 or 60fps? As this is where things are headed then this is something of a white elephant if it doesn't.
Will a 4K2K torrent blow-out the acceptable use policy on my broadband?
Suspect it might!
Why does a image with 4.267 times as many pixels as a 1080p image give rise to such a huge file? 114 50GB blurays is 5.7TB which for a two hour film is 0.8GB/s. I'd love a connection that could download a file this size in a month let alone 'many hours or a few days'.
It's a double-edged sword, this. First, don't forget that it's four times as many pixels as a Full HD image per frame of video. So if there's 24 frames per second, that's a lot more data from the get-go.
Second, there's no compression standard for 4K at the moment - there's no commercially available content that makes it necessary. It's all raw footage, which takes up boat-loads of space.
To put that in context, an uncompressed two-hour Full HD movie might run to something like 800GB, most of which has to be thrown away during compression to make it fit onto a 25- or 50GB Blu-ray disc. So when you look at it like that, it's easy to see how a 4K picture would be in the terabyte range.
It may only get four stars but for £16 I'll take two!

Weird, I updated the price first thing this morning, obviously didn't save in the CMS.
