Before you go out to purchase a new monitor, keep in mind how you’re going to attach it to your existing set up, and whether the cables you’ll need are included with the monitor, or whether you’ll have to purchase them separately. There are a variety of input connections that you might find on your monitor, with the most common being HDMI, VGA, DVI, or display port, and increasingly you might also find USB connections too. As for image quality, if you want HD, you should be looking for a minimum resolution of 1920 x 1080. This 24-inch LED monitor by Dell offers a resolution of 1080p in full HD, with a standard 16:9 aspect ratio. It’s affordable, too.
