Gaming Monitor Fundamentals

Essential Specifications Explained

Refresh Rate: The Foundation of Gaming

Refresh rate determines how many frames your monitor can display per second. Higher refresh rates provide smoother motion, reduced input lag, and competitive advantages in fast-paced games.

Common Refresh Rates:
  • 60Hz: Basic gaming, office work
  • 144Hz: Competitive gaming sweet spot
  • 240Hz: Professional esports
  • 360Hz/480Hz: Elite competitive play
Performance Impact:
  • Input Lag: 240Hz = 4.2ms vs 60Hz = 16.7ms
  • Motion Clarity: 85% improvement at 240Hz
  • Competitive Edge: 23% better tracking accuracy
  • Eye Strain: 40% reduction with high refresh

Resolution: Clarity vs Performance

Resolution determines image sharpness and detail. Higher resolutions provide better visual quality but require more powerful graphics cards to maintain high frame rates.

Essential Gaming Tests

Input Lag Measurement

Input lag is the delay between your mouse/keyboard input and the corresponding action appearing on screen. For competitive gaming, every millisecond matters.

Testing Equipment:
  • • Leo Bodnar Input Lag Tester
  • • High-speed camera (1000fps)
  • • Standardized test patterns
