10 Best Second Monitor 2026 in the United States

The Dell 32 Plus 4K Monitor (S3225QS) is a strong choice if you want a large, sharp secondary screen. Its 31.5-inch size with a 3840 x 2160 (4K) resolution provides plenty of workspace and clear visuals, making it great for multitasking or detailed work. The VA panel gives good contrast (1500:1), so blacks look deep and colors pop, enhanced by wide color coverage (99% sRGB and 95% DCI-P3), which is a plus if you care about color accuracy for photos or videos. The monitor supports a refresh rate up to 120Hz with AMD FreeSync Premium, offering smooth motion that can benefit gaming or video playback, although the 0.03ms response time mentioned may be marketing-speak since VA panels usually have slightly slower response times than IPS panels.

Its matte screen surface helps reduce glare, improving comfort during long use. The ultra-thin bezels and ash white design give it a modern look that fits well in most setups. Dell’s ComfortView Plus technology reduces harmful blue light without dulling colors, which helps reduce eye strain over time. Sound quality has been improved compared to earlier versions, delivering richer audio if you rely on built-in speakers.

If you want a sharp, vibrant second monitor with smooth visuals and decent built-in audio, this Dell model is a solid pick, especially for work, media consumption, and casual gaming.

The LG 27GS93QE 27-inch Ultragear OLED Gaming Monitor is a compelling choice for gamers and power users looking for a high-performance second monitor. Its 27-inch screen size with a QHD resolution (2560x1440 pixels) offers sharp and vibrant visuals, making it suitable for both gaming and professional use. The standout feature is the 240Hz refresh rate, ensuring ultra-smooth gameplay, paired with an impressive 0.03ms response time to virtually eliminate lag and motion blur, which is crucial for fast-paced games.

The OLED panel provides excellent color accuracy and deep blacks, enhanced by the VESA DisplayHDR True Black 400 certification and a 1.5M:1 contrast ratio, delivering stunning visuals in dark scenes. Additionally, the monitor supports NVIDIA G-SYNC and AMD FreeSync Premium Pro for a tear-free and stutter-free gaming experience. Connectivity options are robust with HDMI 2.1 and DisplayPort 1.4, allowing for high-resolution and high-refresh-rate inputs. The monitor also features adjustability with height, tilt, and pivot options, ensuring ergonomic comfort during long gaming sessions or work hours.

The advanced features and performance come at a premium price, which might be a consideration for budget-conscious buyers. Additionally, while the anti-glare screen is beneficial, some users might prefer higher brightness levels in very bright environments. This monitor is best suited for gamers and professionals who prioritize fast response times and superior image quality.

The Philips 24-inch 241V8LB is a solid choice if you're looking for a reliable second monitor with good image quality. Its 23.8-inch screen offers Full HD (1920x1080) resolution, which is sharp enough for everyday tasks like browsing, office work, and watching videos. The VA panel delivers deeper blacks and brighter whites compared to basic panels, helping images look more vivid and true to life. With a 100Hz refresh rate, it provides smoother motion than standard 60Hz monitors, which can be nice even if you're not gaming. The wide 178-degree viewing angles mean colors stay consistent even when you’re not looking straight at the screen.

Connectivity options include one HDMI and one VGA port, covering most common setups, though it might feel limited if you want multiple modern devices connected at once. The screen is nearly borderless on three sides, making it easier to use alongside other monitors without bulky edges in the way. The monitor has a glossy screen surface, which can reflect light and cause glare in bright rooms. The included EasyRead mode is a nice touch for reducing eye strain during long document reading sessions, especially useful for office use. The 4-year advance replacement warranty adds peace of mind.

This monitor is a great pick for office workers or casual users looking to expand screen space with decent color and smooth visuals, but it may not be ideal if you want ultra-high resolution or extensive ergonomic options.
