All Testing Tools

Test your device's rendering performance and measure FPS in real-time with stress testing capabilities.

Measure your reaction time and improve your reflexes with our interactive testing tool.

Measure your display's actual refresh rate and understand your monitor's capabilities.

Check your screen resolution, viewport size, device pixel ratio, and other display specifications.

Check your screen for dead or stuck pixels with various color patterns and tests.

Test your display for backlight bleeding and uniformity issues with dark patterns.

Comprehensive monitor testing suite for dead pixels, uniformity, gradients, color accuracy, and response time.

Find the middle of your monitor with on-screen center lines and a crosshair marking the exact center of your screen in pixels.

Calculate pixels per inch (PPI), pixel density, pixels-per-degree, retina viewing distance, and monitor dimensions from any resolution and screen size, compare two displays, or find the right screen size for your distance.

Test your mouse's polling rate and responsiveness for gaming and precision tasks.

Test your mouse scroll wheel performance, speed, and responsiveness with real-time measurements.

Measure and verify your mouse's actual DPI settings by comparing physical movement with pixel distance.

Convert your in-game sensitivity when you change mouse DPI so your aim keeps the same feel — keeps your eDPI and 360° turn distance identical, with a per-game eDPI check for 100+ games and an equivalent-settings table.

Convert your mouse sensitivity between games like Valorant, CS2, Apex, and Fortnite while keeping the same 360° turn distance, so your aim feels identical — across 100+ games with per-game yaw and eDPI checks.

Test every mouse button in one place — left, right, middle, and side buttons — with live visual feedback, scroll wheel test, CPS tracking, and double-click detection.

Check your mouse for unwanted double-clicks and switch chatter — single-click each button and the tool times the gap, flags faulty fast repeats, and logs every event.

Detect unwanted cursor drift while your mouse sits still — release the mouse and the tool reads raw sensor movement, drift rate, and direction to catch hardware faults.

Test your mouse drag performance and sensor tracking — hold a button and drag to trace the sensor path, measure speed, and catch drop-outs where the button lets go mid-drag.

Measure your mouse movement speed and acceleration in real time — track px/s, IPS, px/s² and G-force with a live speed chart, motion trail, and adjustable update interval.

Spin your mouse in circles and measure your speed in RPM with a timed test — track rotations, live, average and max RPM, spin direction, skill rank, and your personal best.

Test your cursor precision across four modes — path follow, shape trace, precision clicking, and steady hand — with accuracy %, deviation, difficulty levels, skill ranks, and personal bests.

Measure your mouse input lag and response time in the browser across three modes — visual lag, event timing, and click latency — with live processing lag, jitter, consistency, effective polling rate, and benchmark ratings.

Attempt to fix stuck pixels on your screen using rapid color cycling techniques.

Collection of full screen color display tools for testing, photography, video production, and creative projects.

Measure your clicks per second (CPS) with a 1 to 100 second click speed test, tracking your average, max, and best CPS.

Measure how fast you can right-click your mouse with a dedicated right-click speed test, with its own ranks and 1 to 100 second durations.

Measure your actions per minute by hitting moving targets on a 3x3, 4x4, or 5x5 grid, tracking live APM, accuracy, and max APM.

Count any key or a specific key and measure your keyboard speed in clicks per second, tracking your live, average, max, and best CPS.

Test your spacebar's responsiveness and measure your clicking speed and accuracy.

Test your keyboard's responsiveness, detect stuck keys, and measure typing performance.

Check your keyboard for unwanted double key presses and switch chatter — press each key and the tool times the gap, flags faulty fast repeats, ignores held-key auto-repeat, and logs every event per key.

Measure your keyboard input lag and response time in the browser across three modes — visual lag, event timing, and key latency — with live processing lag, jitter, consistency, an effective event rate, and benchmark ratings.

Measure your keyboard repeat rate in Hz — hold a key and the tool times how fast it auto-repeats, with repeat interval, initial delay, a live chart, and max and average rate.

Check your keyboard for ghosting and N-key rollover — hold several keys at once on an interactive on-screen keyboard that lights up every key that registers and tracks your max simultaneous-key count.

Measure your typing speed in words per minute (WPM) with live accuracy tracking, 15 to 120 second tests, and personal best saving.
