Please help - I recently purchased a Pro Display XDR- I use it because of my eyesight as a mirror for my MacBook pro laptop - it works great - however, I also need Windows - I tried Parallels but it does not work with the latest apple architecture - so I purchased a Dell Insperion 3020 desktop from COSTCO - along with a USB-C to Display Port 1.4 (8K) - I cannot get the Dell to display on the XDR - any suggestions? thank you
