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.

    Assuming the software/hardware in the monitor can downscale properly.
    Because I have yet to see a 1440p 27" monitor properly downscale to 720p without being super fuzy, beyond what a 720p should look like at 27"

    Finally, an era where you can buy a computer monitor with a higher resolution than a cell phone screen.

    Keep 'em coming. I'll be reading the reviews on this guy for sure!

    Refresh rate? 60Hz, 120Hz, etc?

    "If the display is using MST to combine two outputs, that puts the emphasis squarely on two DP 1.2 connections."

    Errm, no, the whole point of MST on DP 1.2 is that you can do it over a single connection/cable, because DP 1.2 can normally do two displays per cable, and MST consumes both of them on a single monitor.
  • jeffkibuule - Friday, September 5, 2014 - link

    While you are correct about the purpose of MST, that only works for monitors around 1080p. At a resolution of 5120x2880, you need two physically separate DP 1.2 connections to make that possible.

    Keep in mind that regardless of the number of monitors connected to a single cable, the bandwidth limit is always fixed.
  • Guspaz - Friday, September 5, 2014 - link

    MST is used for 4K@60Hz monitors on DP 1.2, so I'm not sure where you're getting the 1080p from. Dell's 5K monitor is less than double the total number of pixels of a 4K display, so 5K@30Hz is therefore well below the bandwidth limitations of DP 1.2.
  • naxeem - Saturday, September 6, 2014 - link

    Aside from the fact that no sane person would use anything @30Hz.
  • DanNeely - Saturday, September 6, 2014 - link

    For some uses, eg medical imaging where you're looking at highly detailed static images 30hz is fine.
  • iceman-sven - Friday, September 5, 2014 - link

    Finally progress!

    And now in 30" 16:10 please. 5120x3200 or jump straight to 8k 7680x4800. And add Adaptive-Sync/G-Sync support. Please bring a proper HiDPI display. I do not want a 28/32" 16:9 3840x2160 display.
  • piroroadkill - Friday, September 5, 2014 - link

    30" 5120×3200 would be absolutely perfect. I'd be down for that.
