Input Lag & Latency Test

Measure your system's input lag by timing click-to-visual response across multiple rounds. Lower latency means more responsive gaming and better overall experience.

Start Input Lag Test

Click the target as quickly as possible when it appears. The test will measure the time between your click and the visual response. We'll run 5 rounds for accuracy.

Understanding Input Lag

Latency Categories:

  • <30ms: Excellent - Professional esports level
  • 30-50ms: Very Good - Competitive gaming ready
  • 50-80ms: Good - Suitable for casual gaming
  • 80-100ms: Acceptable - Noticeable but playable
  • >100ms: High - May affect gaming experience

Factors Affecting Input Lag:

  • • Monitor response time and refresh rate
  • • Graphics card performance and drivers
  • • Display connection type (DisplayPort vs HDMI)
  • • V-Sync and other display settings
  • • Browser and operating system overhead
  • • Mouse/keyboard polling rate and connection

How to Reduce Input Lag:

  • • Enable "Game Mode" on your monitor
  • • Disable V-Sync in games and graphics settings
  • • Use wired peripherals instead of wireless
  • • Keep graphics drivers up to date
  • • Close unnecessary background applications
  • • Consider a high refresh rate monitor (120Hz+)

Typical Input Lag by Monitor Type:

TN (Twisted Nematic)1-5ms

Fastest response time, best for competitive gaming. Lower viewing angles and color accuracy.

IPS (In-Plane Switching)4-8ms

Excellent color accuracy and viewing angles. Slightly higher response time than TN.

VA (Vertical Alignment)5-10ms

Best contrast ratios and deep blacks. Moderate response time, good for media consumption.

OLED (Organic LED)0.1-2ms

Near-instant pixel response, perfect blacks, excellent for gaming and HDR content.

💡 Note: These are typical hardware response times. Total input lag includes additional factors like signal processing and your system's performance.
