Peterson pointed towards evidence of ghosting in FreeSync displays, which PC Perspective thoroughly documented in its FreeSync impressions piece. (Check out page three for the ghosting discussion.) Evangelho says he saw ghosting effects in the FreeSync monitor he's testing, though the LG 34UM67 monitor we tested here at PCWorld didn't have evidence of it. AMD told PC Perspective that the components chosen by display manufacturers can affect the ghosting.
The story behind the story: Forget 4K, adaptive refresh is the display technology most gamers need. It's wonderful in action. But the competing FreeSync and G-Sync standards introduce a scary new potential for lock-in. Since each type of monitor can only use G-Sync or FreeSync's adaptive refresh technology when paired with a GeForce or Radeon card, respectively, buying one of these displays likely means pledging your allegiance to either Nvidia or AMD for years to come. Displays tend to last far longer than graphics cards.
Choose wisely. Or just sit it out and wait for an open standard to hopefully emerge if you don't want to lock yourself into buying Radeon or Nvidia cards exclusively for the next decade.
