You should also consider refresh rates, which affect the fluidity of movements on your screen. Typical monitors and TVs are locked at 60Hz. That's fine for spreadsheets and more static content, but if you like fast-moving video games, you'll benefit from a display with higher refresh rates like 120Hz. It's much easier to find a cheaper monitor with a higher refresh rate than a TV. Monitors are built for this.

Resolution: This is the big one you've probably heard of, and a higher resolution is generally better, but it's also worth considering the size of the monitor you're getting. The bigger the monitor, the more it will benefit from higher resolutions. That will allow you to have app windows that take up less space but are still legible. Refresh rate: This refers to how many times the display can refresh the picture per second, measured in hertz (or Hz). A higher refresh rate makes the action in games look smoother because you're seeing more information.
