Enlarge (credit: Nvidia) A 24-inch PC monitor with the ability to update its image 500 times per second will be available soon, Asus and Nvidia announced Tuesday. The monitor should boost desktop monitors from the 360 Hz max native refresh rate they see today while putting a mysterious new spin on an old panel technology. Aptly named the Asus ROG Swift 500 Hz Gaming Monitor, it manages high refresh rates with lower resolution.
