The DisplayPort 1.2a spec added support for variable refresh rates in 2014, followed by HDMI 2.1 in 2017.īut manufacturers don’t simply slap on AMD’s “FreeSync” branding and move on. These boards do all the processing, rendering, backlight control, and more. It essentially builds a two-way communication between the Radeon GPU and off-the-shelf scaler boards installed in certified Adaptive-Sync displays. AMD began supporting this technology as FreeSync via its software suite in 2015. You also need a compatible monitor or TV that supports VESA’s Adaptive-Sync. If you’re unsure, check the specifications. Most modern Radeon cards - from budget offerings up to the super-powerful Radeon VII - support FreeSync. What do you need to use FreeSync? Asus’ MG279Q, our favorite FreeSync gaming display.įor FreeSync to work, you need a compatible AMD graphics card or an integrated APU, like AMD’s recent Ryzen-branded all-in-one chips. Nvidia also has its corresponding syncing technology called G-Sync, which is designed to work with its GPUs and is the primary alternative at this time (a bit more on this below). Note: What if you don’t have an AMD GPU? Then FreeSync probably won’t be compatible with your build. With AMD FreeSync, the monitor’s refresh rate scales up or down to match the frame rate, so the monitor never refreshes in the middle of a frame, and tearing never materializes. High refresh rates go a long way in eliminating screen tearing, so adaptive sync technologies are largely unneeded if your GPU consistently outputs high frame rates.īut if you’re playing a newer, graphically intensive game like Assassin’s Creed: Odyssey at 4K, even a powerful gaming desktop might only render 40 or 50 frames per second on average, falling below the monitor’s refresh rate. If you’re playing a relatively simple PC game like the original Half-Life, you probably don’t even need FreeSync. If the GPU’s output drops, the display’s refresh rate drops accordingly. If it’s a 60Hz display, then it only supports 60 frames per second. With FreeSync enabled, the monitor dynamically refreshes the screen in sync with the current game’s frame rate.
