Samsung SyncMaster 721S
The SyncMaster 721S is in fact a successor to the above-described 720B and features a faster matrix with a specified response time of 8 milliseconds. Externally, it is the same silvery case of the DualHinge design that gives you almost unlimited freedom in positioning the screen relative to your desk.
The functionality of the 712S is the same, too. It is equipped with an analog input and an external power adapter and has the same menu with identical options: MagicColor and MagicBright modes, color tone correction, ten color temperature settings, and ten gamma compensation settings. The only difference is that the color temperature settings of the 720B were named just “Warm” and “Cool” in the menu, while the 721S uses specific numeric values. But this is not very important considering the traditionally slipshod color temperature setup in consumer monitors.
