Hi Milah078 ,
Thank you for reaching out Microsoft Community.
I think both monitors will work just fine with the Surface Pro X since those monitors have one USB-C port for power & display. All you need to consider is the kind of cable you'll be using to extend your Surface device display to external monitors. The Surface Pro X has USB-C port, so you should be using a USB-C cable. If in case you'll be using 2 monitors, you have to use a Surface dock to make it work or a supported USB-C Hub.
