Determining the best gaming monitor for your setup used to entail narrowing your list down to FreeSync and G-Sync options, depending on your graphics card. That still applies in many cases, though with Nvidia now supporting G-Sync on some FreeSync monitors, it's no longer cut and dry. To help make things easier, MSI shared a list of its own FreeSync displays that it says are compatible.

"Following Nvidia's announcement of their newest drivers, MSI monitors are effectively G-Sync compatible! This technology allows G-Sync to be used on adaptive sync monitors," MSI says.
