As part of its CES keynote, Nvidia announced that it will begin supporting variable refresh rates (VRR) on FreeSync gaming monitors, beginning with a January 15 driver update. It's big news, because up until now the selection of G-Sync monitors has been limited and pricey, thanks in part to a proprietary hardware module installed in the monitor. Now a software update will automatically expand compatibility to FreeSync monitors that pass Nvidia's quality standards.

The main question is: With hundreds of FreeSync monitors out there, how many will qualify to receive G-Sync certification?
