Looking for a new computer monitor? If you're rocking an AMD-sourced graphics card, you may want to wait a few months. Samsung just announced the UD590 and UE850, the first two monitors with support for FreeSync -- AMD's open-source answer to NVIDIA G-Sync. Both technologies sync GPU output to the monitor's refresh rate, a trick that eliminates visual stutters and tearing. Samsung hasn't announced pricing yet, but says the monitors will be available in 23.6, 27 and 31.5-inch variants.
