Just confirm that your PC is able to output 60Hz on 4k resolution. Modern desktop PCs have DisplayPorts that will handle it (ver. 1.2 and up), but if you only have HDMI output to work with it needs to be version 2.0 minimum.
If you are using laptop with docking station, double check if docking station can support 4k 60Hz, especially if you plan to use more than one monitor (built-in LCD also counts). For example older Dell laptops with docking stations connected through dedicated bottom connector usually supported only 4k 30Hz when more than one monitor was connected. 30Hz suuuuucks real bad for anything other than watching movies.
