60Hz refresh rate

The first thing we need to establish is “What exactly is refresh rate?” Fortunately it isn’t very complex. Refresh rate is simply the number of times a display refreshes the image it shows per second. You can understand this by comparing it to frame rate in films or games. If a film is shot at 24 frames per second (as is the cinema standard), then the source content only shows 24 different images per second. Similarly, a display with a display rate of 60Hz shows 60 “frames” per second. It’s not really frames, because the display will refresh 60 times each second even if not a single pixel changes, and the display only shows the source fed to it. However, the analogy is still an easy way to understand the core concept behind refresh rate. A higher refresh rate therefore means the ability to handle a higher frame rate. Just remember, that the display only shows the source fed to it, and therefore, a higher refresh rate may not improve your experience if your refresh rate is already higher than the frame rate of your source.

What is HDR? 

High-dynamic range (HDR) displays create deeper contrasts by reproducing a higher dynamic range of luminosity. An HDR monitor can make highlights look brighter and deliver richer shadows. Upgrading your PC with an HDR monitor is worth it if you play video games with high-quality graphics or watch videos in HD resolution.

Without getting too deep into the technical details, an HDR display produces greater luminance and color depth than screens built to meet older standards.
