Anyone got a 4k TV/Projector yet?

I have an upscaling JVC Projector. 115" wide screen (not diagonal) at 11 feet viewing distance.
Looks very nice.

The actual beamers deliver already a slight improved color gamut over HDTV (current 1080p standard). The HDTV norm is described by the black triangle. For best video results is a calibration necessary.

Do you own a JVC DLA X55 or X70? A very good projector. Yesterday I have ordered a Mitsubishi HC5 with a nice price, which is identical in construction with a Mitsubishi HC9000.
I have seen so far a picture comparison of 4k vs 1080p by screenshots. The 4k results were subtle better. You have to go very near to the screen. But personal experiences with the result of upscaling to 4k are better than screenshots.

I'm far more excited for 4K DLP projectors than anything else. While the JVC projectors are very nice, I wish they would implement a dynamic iris, and I dislike the softness inherent to three-chip devices.
I wish projector manufacturers would move to LED/Laser light sources already. I really miss having a projector, but I don't really want to buy another one until 4K is mainstream and we are done with replacing lamps every year.

Offering a wider gamut than your source requires is not an improvement - it's actually detrimental to image quality because you're throwing away gradation to bring it into spec.
JVC's projectors are probably the only consumer ones that actually come close to the BT.2020 standard right now.

I think you have to wait for three years until this will be mainstream on the market. The first prototypes are coming by Osram with its phaser projector. This technolgy is to be deliver a lifetime of 20,000 hours vs. up to 5,000 hours of actual technology. http://www.heise.de/newsticker/meldung/Laserprojektion-Osram-holt-den-Phaser-raus-1883352.html
