10 Best 4k Monitor Test 2025 in the United States

The ASUS ROG Swift 32” 4K OLED Gaming Monitor is a robust option for gamers seeking a high-performance display. Its 4K UHD resolution at 3840 x 2160 pixels ensures sharp and detailed visuals, crucial for an immersive gaming experience. The standout feature here is the QD-OLED panel with an impressive 240Hz refresh rate, which delivers ultra-smooth motion clarity, and the incredibly low 0.03ms response time minimizes motion blur, making it ideal for fast-paced games.

HDR support with VESA DisplayHDR 400 True Black adds to its appeal by enhancing contrast and color accuracy, further complemented by 99% DCI-P3 gamut coverage and true 10-bit color depth. These features ensure a vivid and true-to-life display, suitable for HDR gaming and media consumption.

Ergonomics and build quality do not disappoint either, with a 32-inch screen size that strikes a good balance between immersive viewing and desk space. The matte screen surface effectively reduces glare, a beneficial feature for long gaming sessions in various lighting conditions.

In terms of connectivity, the inclusion of a 90W USB-C port is a modern advantage, allowing for convenient power delivery and data transfer. G-SYNC compatibility further smooths out gameplay by reducing screen tearing.

However, potential buyers should consider the device's heat management features, including a custom heatsink and graphene film, which suggest a proactive approach towards OLED burn-in, yet may not fully eliminate concerns over long-term durability. The monitor's weight at 19.4 pounds could be cumbersome for some setups, and its price point might be on the higher side due to its advanced features.

For gamers prioritizing performance and visual quality, this monitor is a strong contender, but those focused on budget or with specific ergonomic constraints might need to weigh these factors carefully.

The Dell 32 Plus 4K Monitor (S3225QS) offers a sharp 4K resolution on a large 31.5-inch VA panel, delivering detailed and vibrant images with strong color accuracy—covering 99% sRGB and 95% DCI-P3. Its 1500:1 contrast ratio and HDR readiness provide deeper blacks and brighter highlights, which is great for movies, photo editing, and general use. The refresh rate goes up to 120Hz with AMD FreeSync Premium, providing smooth visuals and reducing screen tearing—an advantage for light gaming or watching fast-paced videos.

The ultra-low 0.03ms response time is notably fast, although VA panels typically have slower response times than IPS types, so actual motion clarity might vary in very fast scenes. The matte screen helps reduce glare, making it comfortable for long hours, and the ComfortView Plus technology cuts harmful blue light without dulling colors, enhancing eye comfort. The monitor's design features a clean, modern look with ultra-thin bezels and an ash white finish that fits well in a neat workspace. It also improves on sound quality compared to previous models, making the built-in speakers better than usual, though not a replacement for external audio systems.

While the monitor supports HDR, its brightness may not reach the levels of higher-end HDR displays, so HDR content might not appear as vivid as on premium screens. Ergonomics such as height adjustment or swivel are not prominently highlighted, so users should verify if the stand meets their comfort preferences or consider a separate mount. This monitor suits those seeking a large, crisp 4K screen with good color and smooth motion for mixed use—work, streaming, and casual gaming—without stepping into very high-end or professional-grade displays.

The Dell S3221QS 32 Inch Curved 4K UHD monitor offers a lot for those seeking a high-resolution display with a large screen size. Its 4K resolution ensures detailed and clear visuals, making it ideal for watching movies, gaming, or even multitasking with multiple windows open. The curved design adds to the immersive experience by expanding the field of vision, which is great for both entertainment and productivity tasks.

With a 60Hz refresh rate and a 4ms response time, it is not the fastest for competitive gaming but should be sufficient for general use and casual gaming. The 90% DCI-P3 and 99% sRGB color coverage ensure vibrant and accurate colors, which is especially beneficial for photo and video editing. The inclusion of AMD FreeSync helps reduce screen tearing for a smoother viewing experience during gaming sessions. Connectivity options like HDMI and DisplayPort provide flexibility in connecting various devices, and built-in speakers are a nice touch, though they might not replace a dedicated sound system.

The monitor is also VESA certified, which means you can mount it on the wall or a custom stand for better ergonomics. Speaking of ergonomics, it has good adjustability with options to pivot, tilt, swivel, and adjust the height. A flicker-free screen with ComfortView technology helps reduce eye strain during long usage. While the monitor is quite feature-rich, its brightness level of 300 cd/m² might not be ideal for very bright environments. The Dell S3221QS is a solid choice for users looking for a 4K curved monitor with good color accuracy, decent response time, and multiple connectivity options.
