Buyer's guide

How to choose

When selecting a 4K monitor under $400, prioritize screen resolution and color accuracy for productivity tasks. Look for IPS panels for better viewing angles and color reproduction. Consider the refresh rate if you plan on any casual gaming, but understand that high refresh rates are rare in this budget segment. Also, check for essential connectivity options like HDMI 2.0 or DisplayPort 1.4 to ensure full 4K@60Hz support.

Common pitfalls

  • Be wary of monitors advertising 'HDR' at this price point; budget HDR implementations are often not meaningful and can even degrade image quality.
  • Low refresh rates (60Hz) are common and can make fast-paced gaming or even smooth window dragging feel less responsive.
  • Many budget 4K monitors may skimp on build quality or ergonomic adjustments, potentially leading to discomfort during long work sessions.

Marketing to ignore

  • 'Near-4K' resolutions or upscaled content should be avoided; aim for native 4K (3840x2160) for true sharpness.
  • Overly aggressive marketing around 'gaming features' on budget 4K monitors can be misleading; verify refresh rates and response times carefully as they are often compromises.
  • Claims of 'professional-grade' color accuracy are unlikely at this price; focus on monitors that offer decent out-of-the-box color and the ability to calibrate.
