Extend Latitude 5300 display using USB-C

@SunSlick Yes, that will work.  The Latitude 5300 comes standard with a USB-C port that supports video output, and can optionally be ordered with Thunderbolt 3.  But a USB-C to DP cable will work in either case, and yes you will be able to run the display connected that way independently from your built-in display.

Nothing in particular to watch out for.  If you want some futureproofing, you could get a USB-C to DP cable that's rated for DisplayPort 1.4, which is sometimes advertised as supporting 8K displays.  But those cables are still somewhat uncommon, and your system doesn't support DispayPort 1.4, and obviously you're not trying to run a display that would require anywhere near that amount of bandwidth.  So I wouldn't go too far out of your way or pay too much extra for that.  Other than that, there are some USB-C to DP cables and adapters that also include a built-in USB-C port that can operate as a power passthrough, so if you think it might ever be convenient to be able to use a display and charge your system from a USB-C power source at the same time (rather than a traditional barrel-style charger), that might be worth considering.
