4k passthrough bla bla bla. what does that actually mean. I am thinking over my dilemma. If I spend too much on a projector now and in 18 months time, the standard quality for viewing is Ultra HD or 4K, then my projector is not only outdated, it is missing out on a significant development in home viewing since the introduction of High Definition.
This is my point. People who are thinking of buying a projector this year need to work out if they're likely to move over to a 4K PJ in the very near future. If so, it is pointless sending a lot of money on the current (albeit excellent PJ's that can be had between £2-3k. You have to take into account that whatever the carrier is for 4K video, it won't yet be streaming due to slow broadband speeds, and probably not download for similar reasons and due to vast amounts of storage needed for larger collections. Personally I think it'll initially be a disc based format, which will more than likely be a new player that is needed - and probably like DVD and Bluray before it, start around the £1k mark and drop over a period of 12-24 months. I'm guessing discs will initially be more expensive too, maybe £25-30 at a guess. Of course, this sort of format will start out as something for your very favourite movies, and only become the norm when disc prices get down to current Bluray prices. Having said that, the first "RedRay" player is available and is download based - storing films on a 1TB drive, which I'm guessing won't hold many without compression. Personally, I don't see the point in 4K if they're going to compress the hell out of it, so we'll have to wait and see what happens on the source front.
So what does 4 K passthrough mean? Is it possible that source products such as blue rays will be able to play 4k discs and send the signal in Ultra HD through the processor which has a 4k passthrough certification, into the projector which has a similar certification and then display a 4 k image? does that mean that the projector also has to have the 4k passthrough (I am not aware of any yet), in order to carry the signal through the the screen? Is it a case that provided one of the items in the loop has true 4k capability and the others allow the signal to 'passthrough' then the image will remain Ultra HD?
4K pass through means that the AV receiver can pass through a 4K signal to your screen - of course, there is no 4K currently to do that with, so it is marketed as a "future proof" thing. Currently, it is a pointless feature, as chances are 4K players will have dual HDMI2 outputs, so one can be used for the receiver, and one directly to the screen, so not a great loss if current AV receivers didn't have it.
As above, current Bluray players can't play 4K material, not without heavy compression anyway. The projector will need to have be of native 4K resolution to be able to show a genuine 4K picture. The only 4K PJ on the market at the moment is the Sony VW1000ES at just under £17k. All products from source to screen (TV or PJ) will need to be 4K capable.
The exciting thing about 4K is that you will be able to see a movie in exactly the same resolution that it has been shot in. Here's a list of movies so far that have been shot on the "Red One", which is the nickname for the camera: http://www.red.com/shot-on-red
Many classic movies have been or are being specially digitised and remastered to 4K to produce higher quality Bluray releases. But with RedRay, you'll be able to see them exactly as they're shot. That's pretty special for any film fan.
