Screens won't draw on USB connected monitors

  • Anyone else seeing this on Mac or is it just my machine...

    Mac Book Pro

    If I use a USB 3 hub (in my case a Kensington model) to get usb, keyboard, and 2x HMDI monitors connected whenever I launch MA3 OnPC any windows dragged onto those external monitors don't draw. They either start blank white or black, or if they were already displaying something on the internal screen before dragging they stay frozen on that image.

    No other application has issues.

  • USB 3.1 Gen 1 or Gen2 or TB3? I have seen this before, but not with the console.

    The issue could be the required bandwidth for all of the devices. 1 x 1080 output at at 60fps can take 5Gbps, on Gen 1 that is almost the whole pipe, on gen 2 it's 1/2 the pipe. on TB2 and 3 that's 1/4 and 1/8 the pipe respectively.

    While some other applications may work it could be because they are not refreshing the screens at a constant rate. One way to test there would be to play back a movie or something like UFO test on both screens at the same time as see if you get the same issue.

    You could also try reducing the resolution of the external displays, but the mac makes this hard as normally it sometimes just scales and doesn't actually reduce the bandwidth.

  • Unfortunately other apps and movies play fine.

    This is an improvement over the last release where dragging a screen onto the external would simply crash MA3.

    Its usb-c out of the mac into an adapter to usb 3.1(pretty sure). Resolution is only 1920x1080

    If I ever get a spare moment I’ll try test with some other hubs.

    Its only on my admin desk which i rarely use MA at but still curious to get it fixed if I can find out why and pass on to the team.

  • The USB-C cable resting beside a USB-C port on a laptop of a 2-in-1 convertible or notebook, often these compact and portable devices won't cut it. Thankfully, connecting your device to an external display (or even in some cases four) A buggy, outdated, or corrupted graphics driver may be one of the main reasons why Windows 10 won't detect your second PC monitor. To resolve this issue, you can update, reinstall, or roll back the driver to a previous version to fix and restore the connection between your computer and the second monitor.
