I'm not interested at all in the AMD FreeSync/Nvidia G-Sync feature.

My relatively new XPS 8930 has the onboard Intel UHD 630 video. 

I'm seeing some bargains on 27" AMD FreeSync/Nvidia G-Sync monitors and wonder if they'll also work as "conventional" monitors, plugged in to either HDMI or Displayport?

I'm still using my ancient 19" 4:3 monitor at 1280x1024, and it's time to upgrade.
