Buying Guide for the Best Second Monitor
Picking a second monitor can greatly improve your productivity, gaming experience, or entertainment setup. The right choice depends on understanding how you'll be using the extra screen—will it be mostly for work, gaming, creative projects, or just casual browsing and video? Once you're clear on your main uses, you should look at several key features that determine the monitor's overall performance and suitability for your needs.Screen SizeScreen size refers to the diagonal measurement of the display, usually in inches. It determines how much content you can see at once. If you need lots of space for multitasking or viewing large documents, a bigger screen—typically between 27 and 34 inches—can be helpful. Smaller monitors (21–24 inches) work well for limited desk space or if you want something compact for reference or chat windows. Match the size to the space you have and how close you'll sit to the monitor to avoid eye strain.
ResolutionResolution describes how many pixels the monitor displays, which affects image sharpness and clarity. Common resolutions are Full HD (1920x1080), Quad HD (2560x1440), and 4K (3840x2160). Full HD is usually enough for basic work and web browsing, while higher resolutions like QHD or 4K are better for design work, watching movies, or if you want sharper text and images. Choose a resolution that matches the size of your monitor—larger screens benefit more from higher resolutions.
Panel TypePanel type refers to the underlying technology of the display, usually IPS, TN, or VA. IPS panels offer better color accuracy and wider viewing angles, making them great for creative work and everyday use. TN panels have faster response times, which can be beneficial for gaming, but narrower viewing angles and less vibrant colors. VA panels provide deeper contrast and good colors, often a middle ground. Pick an IPS if you want all-around good quality, or TN for fast-paced gaming.
Refresh RateRefresh rate measures how many times the screen updates per second, shown in hertz (Hz). Higher refresh rates—like 75Hz, 120Hz, or even 144Hz—make motion look smoother, which is especially noticeable in gaming or video editing. For basic office or general use, 60Hz is typical and sufficient. If you do a lot of gaming or fast-paced work, a higher refresh rate might be worth seeking out.
ConnectivityConnectivity covers the types and number of input ports, such as HDMI, DisplayPort, USB-C, and VGA. Make sure your monitor has ports compatible with your computer or laptop. HDMI and DisplayPort are common and support high resolutions and refresh rates. USB-C can be useful if you want a single cable for video and charging, especially with newer laptops. Think about what devices you'll be connecting and choose accordingly.
Ergonomics and AdjustabilityErgonomics refers to how much you can adjust the monitor—like tilt, height, pivot, and swivel. A more adjustable monitor is easier to set up for comfortable viewing, which is important if you spend long hours at your desk or have a specific desk setup. If you'll use the monitor in portrait mode for coding or reading, look for pivot adjustability. Pick a monitor with good ergonomic options if comfort and long-term use matter for your setup.
Color AccuracyColor accuracy is about how true the colors appear on your monitor compared to real life. It's measured with coverage of color spaces like sRGB or Adobe RGB. This is most important for photographers, designers, and anyone doing color-sensitive work. For normal office tasks or entertainment, excellent color accuracy is less critical. Consider this spec if your main tasks require precise color representation.
