JVC X70 Projector Design and Setup
From the outside, you could easily confuse the X70 for the X30 model. The main difference you can spot is a motorized lens cover that opens and closes when using the projector. Of course there are major differences on the inside, with none being greater than the e-Shift technology that JVC is using here.
e-Shift produces an image with greater pixel fill and potentially greater resolution by producing a second image that is shifted half a pixel over and up. When this was first announced many people were quick to refer to it as 4K, but it still only has a 1920x1080 sensor and as these pixels overlap on the shift, it isn't producing a true 4K image. The X70 projector also has no ability to accept a 4K signal, so it can only interpolate a 1080p signal into something higher.
Beyond the new e-Shift, the X70 also includes THX and ISFccc certification as well as a fully user accessible CMS system. This is the first projector I've seen that includes a chart of popular screen materials, so you can input your screen type and have the projector automatically account for color and tint shifts introduced by the material. The e-Shift technology also allows for a very precise 121-point alignment grid for fixing any convergence issues. Getting perfect convergence out of a three-panel projector is hard to do, and is perhaps the biggest benefit of the new e-Shift technology.
JVC relies on an external emitter for their 3D glasses, but it can simply be setup on top of the projector and reflect the signal off the screen. For those that have harder placement issue than I do, I wish JVC used a generic Cat5 or Cat6 cable for connecting this emitter than their custom cable, as it makes long distance installation easier and cheaper. The lens memory system works quite well, so I setup 1.78, 2.20, and 2.40 aspect memories for my 2.40 screen in less than 10 minutes. For my initial viewing I chose the THX profile and entered the code for my screen, a 122" Screen Innovations SolarHD 1.3 gain, as I imagine this would be the most common way for users to set it up. Advanced calibration will be covered in the bench test section.
