How to use my Mac as a display for my (windows 10) work laptop.

Hi, I have:

a 2017 iMac, with thunderbolt 3 ports (home)
a Dell Latitude 5285 table PC, with USB-C ports specced at usb-3 speed, not thunderbolt (work)

How can I work from my iMac? e.g. use a desktop on my iMac as a screen for my Windows PC.

I have tried:

1) Using Remote Desktop and VNC, to connect to my PC. (laggy and work don't like this)

2) AirServer type apps, AirPlay, I never go this working.

3) The native windows remote display. I never got a Mirriorcast Server on my mac to work ... :(

4) Cable and the mac "display mode" Command-F2. This does not appear to work on my Mac.

Thank you for any advice from anyone who has got this working.

Craig, no can do... Apple dropped the Target Display function after Mid 2014 iMacs. :(

27-inch iMac models introduced in 2009 and 2010: Use a Mini DisplayPort cable to connect your iMac to a Mini DisplayPort or Thunderbolt or Thunderbolt 2 port on the other Mac.
All iMac models introduced in 2011, 2012, 2013, and mid 2014: Use a Thunderbolt cable to connect your iMac to a Thunderbolt or Thunderbolt 2 port on the other Mac. If the other Mac uses Thunderbolt 3, you can use the Apple Thunderbolt 3 (USB-C) to Thunderbolt 2 Adapter with your cable.

Target display mode requires macOS High Sierra or earlier on the iMac used as the external display. It does not work with macOS Mojave or later.

Craig,

+1, that isn't going to happen. If your work laptop needs an external display then you need to order one or work with your IT department to see if they have one you can use. iMacs are computers, they are not displays for other devices.
