The best monitor for you depends on how you use it, and a few common slip-ups can leave you with the wrong one. Shopping for a new monitor the same way you'd buy a TV can come back to bite you. Unlike a TV, which usually sits across the living room, your monitor sits much closer to your eyes. A screen that's too big (or even too small) will end up straining your eyes and make work much harder. A good rule of thumb is to match the screen size to how far back you sit. If your eyes sit around 24 to 36 inches from your current monitor, a 27-inch monitor is ideal. At roughly 28 to 42 inches, a 32-inch monitor works well.
Not checking whether your PC and ports support the monitor is another frequent error. Before you buy that new 6K HDR10+ monitor, don't forget to consider your other devices and see if they're compatible with such astounding specs, especially if they're relatively old. For example, not every laptop can push out 4K at 60Hz through every port, so a 4K monitor could be limited on your current setup. Older HDMI ports, like HDMI 1.4, top out at 4K 30Hz, while HDMI 2.0 and Display Port 1.2 support 4K at 60Hz. Even everyone's favorite, USB-C, can't always support video because the port needs to either support Display Port or be a Thunderbolt port to do so. Not checking the monitor panel type before you buy is also critical. Monitors don't just come in different sizes; they also come in different panel technologies. Each has its own pros and cons, and the ones you're likely to come across are IPS, TN, VA, and OLED. The first three are all LCD panels, while OLED is a separate technology. TN panels are great for gaming because they are fast and more affordable than the others, but they have poor viewing angles.
