    Dell UP2715K monitor, Windows 10 Update (1803) broke 5K support


    I have a PC that wasn't used for over a year, so it was a long way behind in Windows Updates.

    It has an Nvidia GTX 960 graphics card, which had been running a Dell UP2715K 5K monitor quite happily for a year or two at full 5K resolution, using 2 x DisplayPort connections.

    Yesterday I used the Upgrade Assistant to update to the most recent version of Windows 10 x64 (1803).

    This seems to have totally broken 5K support for the monitor. Even though it still shows in display settings as being 5K resolution it only shows half the image (stretched to the full width of the screen). So instead of the screen showing pixels 0...5120 it instead shows pixels 2561...5120.

    I've updated to the latest Nvidia drivers but it made no difference. At the moment the only way I can use the monitor is to unplug one of the DP cables and run it at 3840 x 2160.

    Does anyone have any ideas?

    :)

  2. Windows Creator Update Broke My Monitor

    Still doesn't work, confirmed with Microsoft tech support. Their advice is to not install the Creators Update until it is offered through the normal update process. DO NOT force apply it. The support person said that it would not be offered until the update
    process could determine compatibility.

    Working with no problems on Win 10 Anniversary Update

    As all 5K monitors for Windows are now out of production, it appears that 5K is now an exclusively Apple technology. Whether Nvidia and ATI are going to have any interest in continuing support or correcting problems is, well, up in the air. A funny solution
    is to run Windows 10 on an older iMac or MacPro, the ones with the dual Thunderbolt
    2 ports.

    My system for reference:

    HP Z420

    Xeon 6-core E5-1650

    40GB ECC RAM

    PNY Quadro K1200 video card

    HP Z27Q monitor: 27" 5K

    BTW, Adobe Lightroom is much nicer on 5K than on 4K. Probably even better on 8K but I'm not going to be a monitor resolution pioneer again. Would probably have to sell my car to buy the only 8K monitor on the market anyway (Dell).

    Research seems to indicate that this problem is unique to Nvidia Video cards and that the ATI FirePro seems to work fine. But I hate to throw away a 1 year old, $400 card.

    Dell to Price its 27-inch 5K Monitor Under $2,000

    Dell plans to launch the first consumer 5K monitor some time in December 2014, priced at just under $2,000 a pop. This comes in the wake of Apple launching the first consumer product with a 5K display, its latest iMac Retina all-in-one desktop. Dell's UltraSharp UP2715K is a 27-inch display with 5K (5120 x 2880 pixels) native resolution, which lends it a staggering 218 ppi of pixel density. Compare that to the 157 ppi of 28-inch Ultra HD monitors. 5K is four times as many pixels as WQHD.

    The UltraSharp UP2715K features a 10-bit IPS panel, with 99 percent Adobe RGB and 100 percent sRGB palette coverage, and a 12-bit LUT. It offers viewing angles of 178°/178°, 8 ms response time, 350 cd/m² maximum brightness, and 1000:1 static contrast-ratio, with dynamic mega-contrast. The display needs two DisplayPort connections for sufficient bandwidth, to beam those many pixels at 60 Hz. There's also a mini-DisplayPort, but using that would either cap resolution at 3840 x 2160 @ 60 Hz, or drop refresh-rate at the native resolution.

    Windows 10 April 2018 Update(SCU) Partially Breaks MKV File Support?

    Yeah, they play perfectly fine.

    Thanks, this did the trick perfectly!

    I'm scratching my head then, because so far every computer I update to 1803, even fresh installs, can no longer read the details of mkv files. But at least icaros fixes the problem for now. Hopefully the bug is fixed in Windows natively eventually.
