    4k Dilema

    I recently purchased Samsung U32J590 4k monitor to try hands on 4k gaming. I have attached it to my 1080 GTX which got 3 display ports and 1 HDMI where as monitor got 2 HDMI ports and 1 display port.

    Now if I attached them via display port, I can't get 4k resolution at 60Hz as only option is 29/30 Hz but I can turn G-sync on through nVidia control panel.

    On the other hand, if I connect it with HDMI cable; port 1 on monitor, I can get 4k resolution but again 29/30 Hz where if I connect it to port 2 on monitor, I can run 4k with 60 Hz but then no G-sync.

    How to get around running display port with 4k 60hz with g-sync?

    (I have checked in monitor settings that display port is set to 1.2 not 1.1)

    Does Miracast support 4K?


    We suggest that you check with the manufacturer of the 4k display device that you are using if it is certified to work with Miracast. If your display device is certified to work with Miracast, then check if your PC device supports Miracast. You may do so
    by following the steps below:

    • Click Start, then go to Settings >
      Projecting to this PC
    • Check if your device supports Miracast.

    displaylink (dynadock 4k) not working with windows 10 laptop

    I have a Toshiba dynadock 4k with an external monitor but I cannot see this monitor listed in my Windows 10 laptop display settings and cannot make my display appear on second monitor.

    DisplayLink website suggests this may be a Windows 10 issue.

    How do I get this working?

    HDR and WCG will not turn on for 4k 60hz, only 30hz.

    Hi UmeedMalik,

    Issue like this might be due to an outdated videocard driver. I'd like to get more information regarding this so we could further check and provide a more established workaround. Please answer the following:

    1. What is the current build and version of your Windows 10?
    2. Is this the first time that you are trying to connect your PC to your TV?
    3. What type of cable did you use to connect your computer to your TV?

    In the meantime, try the following suggestions to isolate the issue:

    • Download and install all the suggested Windows cumulative and security update.
    • Install the latest video card driver. Download it directly from the manufacturer's website.
    • Use a different HDMI cable. Check if your video cable supports 4k 60hz resolution. Some HDMI cable only supports 30hz at 4k.
    • Try connecting your PC to you TV alone. This will help us eliminate hardware conflict issues.

    If you would like me to provide additional advice, simply respond to this thread. I will get notified and I’ll reply to you as soon as I can.
