A monitor that’s positioned too high or too low — or too close or too far from you — is a recipe for neck and shoulder pain.Unlike the stand that comes with most monitors, a monitor arm provides flexibility to position your screen exactly where you want it for proper ergonomics and comfort. It can also free up space on your desk and help your workspace look neater.After assessing 25 monitor arms ranging in price from $50 to $335, we found that the Herman Miller Jarvis Single Monitor Arm is the best option.It moves smoothly into a wide range of positions and angles, holds monitors up to 32 inches in size steadily and securely, and is easy to set up. It’s also backed by the longest warranty we’ve seen for a monitor arm.If you’d like something that’s more of a desk shelf to raise your screen, we recommend the Amazon Basics Adjustable Computer Monitor Riser Desk Stand as a simple, inexpensive option.
