Display Tests
Dead Pixel Test
Cycle through fullscreen solid colors to find dead, stuck, and hot pixels on any monitor, laptop, phone, or TV. Learn how to tell a real pixel defect from dust and what to record for a return.
Touch Screen Test
Draw across a fullscreen grid to find touchscreen dead zones and check how many simultaneous touches your phone, tablet, or touch laptop reports.
Frame Skipping Test
Photograph a numbered frame sequence to see whether your monitor drops frames at its overclocked or custom refresh rate. Includes camera settings and how to read the photo.
Uniformity Test
Check a monitor for uneven brightness, clouding, dirty screen effect, and color tint with gray and solid-color patterns, and learn what level of non-uniformity is normal.
Gamma Test
Compare your display's gamma against 1.8, 2.2, and 2.4 reference patterns, and learn how gamma affects shadow detail and how to adjust it.
Black and White Detail Check
Check black crush and white clipping with near-black and near-white steps. Find the brightness, contrast, and RGB range settings that keep shadow and highlight detail visible.
Response Time Test
Watch moving test patterns for ghosting, inverse ghosting (overshoot), and motion blur, and compare overdrive settings to find the cleanest motion on your monitor.
Refresh Rate Test
See the refresh rate your browser is actually rendering at, check frame pacing, and fix a monitor stuck at 60Hz with cable, port, and OS settings.
Burn-in Test
Check OLED and plasma screens for burn-in and image retention with solid colors and full-screen patterns. Learn the difference between temporary retention and permanent burn-in.
Color Temperature Test
Compare white point presets, Night Light, and warm or cool picture modes on one fixed white reference, and learn what 6500K (D65) means for photo and video work.
Backlight Bleed Test
Check an LCD for backlight bleed and IPS glow on a dark fullscreen pattern, learn how to tell them apart, and see how to photograph bleed without exaggerating it.
Gradient Banding Test
Look for color banding and posterization in smooth gradients, and find out whether the cause is the source file, GPU settings, color management, or the panel.
HDR Capability Check
Check whether your browser and display report HDR and wide-gamut support, then work through the Windows and macOS settings that decide whether HDR is actually on.
Flicker Test
Use your phone camera and a set of brightness levels to look for PWM backlight flicker, and learn which settings and monitor features reduce visible flicker.
Browser Reaction Time Check
Measure your click or keypress reaction time over five trials and see how mouse polling, refresh rate, and display latency each add to the total delay you feel.
Viewing Angle Test
See how color, contrast, and gamma shift as you move off-center, and compare typical viewing-angle behavior of IPS, VA, TN, and OLED panels.
Screen Info
See your screen resolution, device pixel ratio, color depth, and HDR support as your browser reports them, and calculate pixel density (PPI) from your panel size.
Viewing Distance Calculator
Calculate a viewing distance for any monitor or TV from its diagonal, aspect ratio, and the horizontal viewing angle you want, with the formula shown step by step.
Text Clarity Test
Compare text rendering, ClearType and font smoothing, scaling, and color fringing on sample text, and fix blurry or fuzzy text on Windows and macOS.
Multi-Screen Alignment
Line up dual and triple monitor setups with alignment guides, check that edges meet, and compare brightness and color between screens side by side.
