I recently got a new 4K monitor and now whenever I play a video on this monitor, VLC only displays the video in the upper left quarter of the screen, when it's running in a window or full screen. When running in a window, the video display is actually somewhat falls slightly outside (to the left) of the main VLC window.
The resolution of the video makes no difference.
I tried a different player, Media Player Classic Home Cinema, and it plays it perfectly, but I would rather figure out how to get VLC to work.
I am running Windows 10 with a GTX 1060 video card.
I have completely no idea where to even start looking to troubleshoot this, I've done a fair amount of googling but haven't found anyone else with this problem.
