Quote:TechSpot has now tested seven FreeSync displaysSEEAMAZON_ET_135 See Amazon ET commerce with an Nvidia graphics card to try and determine exactly what kind of problems Nvidia gamers might or might not encounter. There have been literally hundreds of FreeSync displays, but by testing some of the more prominent models, reviewers should be able to spot-check whether the problems with FreeSync compatibility are as dire as Jen-Hsun predicted. First, the website tested the following six:
- Acer KG251QF (24-inch, 1080p, 30-144Hz)
- BenQ EL2870U (28-inch, 4K, 40-60Hz)
- Viotek GN24C (24-inch, 1080p, 48-144Hz)
- AOC C27G1 (27-inch, 1080p, 48-144Hz)
- Viotek GN32LD (32-inch, 1440p, 48-144Hz)
- Philips Momentum 43 (43-inch, 4K, 48-60Hz)
Each of the displays above worked flawlessly, with all features and supported capabilities enabled.
The seventh and only panel that failed to work with Adaptive Sync on an Nvidia GPU wasn’t a surprise. The Viotek NB24C only supports FreeSync over HDMI, which AMD implemented via a custom protocol, whereas Nvidia is only supporting FreeSync via DisplayPort. HDMI won’t add support for Variable Refresh Rate (that’s the formal name of the term) until HDMI 2.1. This does have implications for TV support since most-to-all of the FreeSync TVs currently available only support it over HDMI. (It’s not clear if any TVs are implementing this capability over DisplayPort.)

There’s always the possibility that specific displays will prove to be incompatible with GeForce cards, but TechSpot’s findings echo our own expectations that there’s no fundamental problem with FreeSync as a standard. Features like HDR and Low Framerate Compensation appear to be fully supported as well. Despite the negative conversation around FreeSync support at CES, Nvidia’s engineers appear to have done their job well as far as compatibility and support.
