The Viewsonic XG2401 (See it on Amazon) is the company's mid-range 24" gaming monitor and it costs a bit more than the base models due to the fact that it has FreeSync adaptive refresh rate technology, which is all the rage these days. It has HDMI and DisplayPort video inputs for fast-paced gaming, three USB ports for peripherals, and a 144Hz refresh rate too (DisplayPort-only) making it a well-equipped piece of gaming hardware.
