UHD is dead. Not really, but it would seem that displays bigger than UHD/4K will soon be coming to market. The ability of being able to stitch two regular sized outputs into the same panel is now being exploited even more as Dell has announced during its Modern Workforce livestream about the new ‘5K’ Ultrasharp 27-inch display.  The ‘5K’ name comes from the 5120 pixels horizontally, but this panel screams as being two lots of 2560x2880 in a tiled display.

5120x2880 at 27 inches comes out at 218 PPI for a total of 14.7 million pixels. At that number of pixels per inch, we are essentially looking at a larger 15.4-inch Retina MBP or double a WQHD ASUS Zenbook UX301, and seems right for users wanting to upgrade their 13 year old IBM T220 for something a bit more modern.

Dell has been pretty quiet on the specifications, such as HDMI or DisplayPort support, though PC Perspective is reporting 16W integrated speakers. If the display is using tiling to divide up the transport workload over two outputs, that puts the emphasis squarely on two DP 1.2 connections. There is no mention of frame rates as of yet, nor intended color goals.

Clearly this panel is aimed more at workflow than gaming.  This is almost double 4K resolution in terms of pixels, and 4K can already bring down the majority of graphics cards to their knees, but we would imagine that the content producer and prosumer would be the intended market. Word is that this monitor will hit the shelves by Christmas, with a $2500 price tag.

    Thumbs up!!!!!!

    5120x3200 or better 7680x4800 and Adaptive-Sync/G-Sync support.

    My head hurts, so if I take 2x 1440p screens which both have 3.7 mill pixels and place them next to each other then I have 7.4 mill pixels, but if I take 2560 x 1440 double that to get 5120 x 2880 and do that sum I get 14.7 mill pixels?

    Num_pixels = width*height.

    One display:
    2560x1440 = 3.7 million pixels

    Two displays next to each other:
    2*(2560x1440) = 5120x1440 = 7.4 million pixels

    One 5k display:
    (2x2560)x(2x1440) = 5120x2880 = 14.7 million pixels

    The key is that doubling both dimension, is quadrupling the pixel count :)

    If you take two squares and place them next to each other, you will get something with twice the space, right ? But only one of the axis will have double the length of one square. To get double the resolution, you have to double each axis, so you would actually need 4 1440p panels stitched together to get a 2880p panel.

    2560x1440 = 3.7 million pixels.

    Two 1440p screens = 7.4 million pixels.

    5120x2880 is double in both directions. FOUR (two horizontal x two vertical) 1440p screens = 14.7 million pixels.
  • TrevorH - Friday, September 5, 2014 - link

    Surely 5120x2880 would be 4 x 2560x1440 displays stitched together not two?
  • Ian Cutress - Friday, September 5, 2014 - link

    Derp, it's most likely two 2560x2880 lots through MST.

    I have a U3011 (last 16x10 display at 2560x1600) and it looks spectacular for images, but sitting close, small text is not that readable. This may have been from improper font smoothing though since I was mostly working via vnc connection. I don't think you need anywhere near this resolution for gaming, but it certainly helps with text readability. If you wanted to use it for gaming, you may be able to just run it at 2560x1440, although I don't know how well that works via MST or whatever you are using to drive this high resolution.
