Your Eyes Aren't Sharp Enough To Justify This 9.6-Inch 4K Display

Today Ortus Technology, a Japanese manufacturer of industrial flat panel displays, announced a new 9.6-inch TFT boasting a whopping resolution of 3840x2160. For those keeping score, that happens to be the newly appointed 4K UHD standard, and the same as Sony's $US25,000 84-inch behemoth.

Except that on an 84-inch TV your eyes have an actual chance of discerning all those extra pixels, providing a more immersive viewing experience than HDTV. On a 9.6-inch display you'll never be able to get close enough to warrant all those extra dots. Your eyes simply aren't that sharp, and they never will be. The company claims the displays will be well suited to medical applications, and professional broadcast gear where high-resolution imagery is important. But at 458ppi Ortus' screen crushes even the iPhone 5's retina display, and when was the last time you were able to discern an individual pixel on that? [Ortus Technology via Tech-On!]


    Announcements are great and all, but it's still near impossible to find a 1080p or even 720p 8" screen out in the wild that isn't built into an existing device.

    Yep, your eye can totally tell. Its all in the sharpness - we use anti-aliasing and color space "tricks" at present to make displays look "nice", but nothing beats raw resolution.
    For reference, this is less than the dot-pitch of a high quality quality printed page or indeed an old-school film photo printed at this size. One other application for such resolution is a 3D heads-up displays, which needs much higher "static" ppi. Viewfinders in military applications can benefit from resolution like this. Once we get to 1200- ppi, then its ridiculous :-)

      This sounds like the sort of argument people use to sell $80 monster HDMI cables.

    I have an IPad with retina display that has 1 dead pixel and I can see it clearly, in fact it bugs the hell out of me :-).
