Playstation 4 will support 4K gaming

One guy, super convincing argument. I personally wouldn't ever spend the money on anything over $3k because the returns diminish so quickly, but the utter BS numbers on the consumer side don't at all jive with the actual image quality and characteristics. And I'm not interested in convincing anybody that their preferred tech is better or worse, these arguments are soooooooooo 2009.

Jeff,
I believe the Red projector is LCOS spacial modulated laser light.
You know that you cant direct scan a laser onto a screen at this time, right ? Against the law.

Haha. Yeah, Tom, living in a truck has its disadvantages. Looks like the new digs in Dubai should cure a lot of that.

I agree with Andrew about the Sony projectors. The LCOS systems are milky and black/shadow detail really suffers. Unfortunately, they have the best resolution at the moment until the new laser units (like RED's) hit the market. The DLPs have superior color rendition and much better blacks, the "rainbow" effects have mostly been eliminated on the latest systems, it's rare that I see them and I'm highly sensitive to it. Where the DLP units currently suffer is they're "wobulated". This gives an artificial resolution boost while incurring some spatial and temporal distortion on the image. Effectively, the DMD unit rocks side to side as each frame is scanned so that many pixels/elements are used twice in the scan to boost the resolution. Full-raster 3840x2160 DMD systems are in testing now, but we probably won't see them in a commercial product for at least another 6 months.

I too am building a theatre / coloring room with the intent of adding a 4K projector. I've been talking about building it for the past 2+ years and it's finally time. I have my remodel permits in hand and will be starting in about 20 days when my schedule clears a bit. I have a 1080p JVC projector that was in a corporate installation and pulled recently and I'm going to install that in the interim until I decide which 4K projector to go with. My money is betting on RED at this point, but so far we haven't seen the goods. I was at RED Studios two weeks ago and in their theatre they had the RED projector, the Sony 4K and a Christie. Only saw the Sony one operate. The RED projector showing at NAB was a bit hard to quantify. It was running at 1/4 resolution and didn't have the proper screen to eliminate ghosting with the 3D. On the other hand, I thought the color rendition and overall range was excellent.

I see a lot of arguments over and over again about variouse things around here. What the reality was, is reality, numbers. People, super optimal people apparently can resolve like around 30k across in monochrome, or something. Us, non optimal, lesser mortals, apparently, struggle with a tenth of that (in each direction) or even noticing it, that is one thing that produces a lot of negativity against higher resolutions. Just because we don't notice it or enjoy it, does not mean that others won't, and it is not valid, so it is valid. What is not appreciated is the other uses, not just editing photographs.

Many, many years ago, I was excited about digital paper. I wanted to do a document editing work bench solution (think Microsoft surface) in 4k for my design work, so I could have over 8 or more sections of a design document open at once. But it is not just for design documents, a number of document and office work would really greatly benefit from this, even everyday home desks. The thing is you don't have to store things on your desk, you can store it on your screen. Reliability (design) in modern computing is an awful issue though. With these things you will need a lot of resolution, just to have full HD in your greater angle / focus of vision. Over 40 inches you will need greater than 4k. To get 4k (preferable) you will need over 8k. If you have a 80 inch office desk (or co-operative work desk) you now are talking 16k+. So there are legitimate drivers out there, but I think everyday consumer screen in front of you, in the modern scence, will struggle to get past 8k, even 4k unless they have a very large screen. I know a company with 8k display I am thinking of approaching on these issues.
