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. So, what's the difference? As an open standard, AMD's kit is free to implement, meaning Samsung can integrate it into its new monitors without paying out licensing fees. Samsung hasn't announced pricing yet, but says the monitors will be available in 23.6, 27 and 31.5-inch variants.
