>I've always wondered whether there is a market for just a panel with a single HDMI input.
Checkout the Korean white label TV's and monitors Ebay they use LG and Samsung panels usually come with the most basic features (the vast majority of them don't have a tuner cheaper, and avoids hideous import taxes for most the world) but then again you get a 65" 4K TV for less than 2000$.... e.g. http://stores.ebay.com/Dream-Seller/UHD-3840-x-2160-/_i.html...
How is that cheating? Display technology goes through a bunch of stages before being ready for mass consumption and the first stage after getting 'off the drawing board' would be to feed it data and to see what it looks like with stills. Still images are much harder to get right than motion in display technology because you have just about forever to determine what it looks like. With moving images the eye is much more forgiving.
Display calibration is always done with stills.
Really, this is a huge step for display tech and it seems a bit much to demand systems integration at that same level right away as well. This is not a product, it's a technology demo.
