Resolution & scaling
Confirm native resolution and device pixel ratio at 100% OS scaling before chasing ghosting or color issues. Open test
TipWrong scaling makes text fuzzy and wastes panel pixels
Display test center
Pick a dedicated test below — each has its own customization panel, fullscreen inspection, and keyboard shortcuts. No install required.
Suggested new-monitor workflow
Run these six tests in order during your return window — each opens a dedicated instrument with its own controls.
Refresh rate
Verify the panel actually runs at its advertised Hz — many 144Hz monitors ship stuck at 60Hz until you fix the cable and OS setting. Open test
TipUse Display settings + our live Hz chart
Dead & stuck pixels
Fullscreen white, black, and RGB cycles make bright dead subpixels and dark stuck pixels obvious in a dim room. Open test
TipBlack finds stuck-on pixels; white finds dead ones
Uniformity & bleed
Grey fields expose vignette and tint; pure black in a dark room separates IPS glow from fixed edge bleed. Open test
TipDim the room — ceiling light hides edge leak
Ghosting & banding
Moving patterns reveal VA smear or slow overdrive; gradient ramps catch 8-bit banding before you keep the panel. Open test
TipFinish with refresh rate again if gaming or VRR matters
Color & HDR
Check grey ramps and sRGB mode, then stress peak brightness if you bought an HDR display — banding shows up on cheap panels. Open test
TipUse factory sRGB or calibrated mode for the final pass
All display tests
Each test has its own settings panel, fullscreen mode, and keyboard shortcuts.
Dead pixel test
Custom color sequence, cycle speed, and keyboard navigation for stuck and dead pixel checks.
Uniformity test
Custom grey fields, grid overlay, and crosshair for vignette and tint checks.
Backlight bleed
Bleed-focused preset — pure black fields with grid overlay for IPS glow.
Color calibration
White balance D50–D75, 24-patch color checker, and skin tone references for display color accuracy.
Gradients & banding
RGB and grey ramps with step count, direction, and bit-depth controls for banding checks.
Monitor ghosting test
UFO-style motion patterns for screen ghosting, motion blur, and inverse ghosting.
Refresh rate
Live Hz sampling with adjustable chart, spike threshold, and motion block speeds.
Resolution checker
Resolution, viewport, DPR, color depth, and HDR capability readout.
Screen size calculator
PPI and physical width/height from diagonal inches and resolution.
Aspect ratio calculator
Simplify ratios, resolve missing sides, and compare common formats.
Burn-in test
Sliding bars, checkerboard, and gradient sweeps with adjustable speed and cycle time.
HDR test
Reference white patches with live HDR detection and customizable patch sequence.
Color blindness test
Fullscreen hue-separation plates and red-green / blue-yellow pairs — a screen color check for UI and panels.
RGB channels
Pure primaries, per-channel ramps, and repeating RGB bars for subpixel isolation.
Flicker / PWM
Free monitor flicker test online — PWM, OLED, and screen strobe checks at low brightness.
Crosshair / alignment
Precision dot, geometry, and alignment cross for monitor center and overscan checks.
Sharpness & text
Pixel grids, fine lines, multi-font text samples, and subpixel rulers for clarity checks.
Screen tearing
Fast-scrolling stripes to detect VSync-off tearing and verify G-Sync or FreeSync.
Color gamut (sRGB / P3)
Side-by-side sRGB and Display P3 patches to verify wide-gamut coverage.
Blooming / halos
Bright highlights on black for local-dimming bloom and HDR halation checks.
Viewing angle
Grey ramps, primaries, and skin tones with guided off-axis position prompts.
How to use the display test center
Open a dedicated test, adjust its panel, then inspect in fullscreen — no install required.
-
Step 1
New monitor? Follow the six-step setup checklist at the top of this page — resolution, Hz, pixels, bleed, ghosting, and color.
-
Step 2
Open any test card — adjust settings in the panel, then press Start or click the preview for fullscreen.
-
Step 3
Use arrow keys and F on most tests to cycle patterns and toggle fullscreen without leaving the test surface.
Why use display tests?
Each check targets a different panel flaw — pick the right tool instead of one generic slideshow.
Dead pixel test
Custom color sequence with adjustable cycle speed — the dedicated dead pixel test replaces basic solid-color cycling with full control.
Panel uniformity
Grey fields, grid overlay, and crosshair for backlight bleed, vignette, and tint — with a bleed-focused preset on its own route.
Full monitor QA
Gradients, ghosting, refresh rate, HDR, and burn-in tests each expose useful parameters so you can inspect like ScreenTester without leaving the browser.
Display test center FAQs
What is a screen test?
A screen test displays solid colors or diagnostic patterns on your monitor, laptop, phone, or tablet so you can inspect pixels, contrast, and color accuracy. TestMyGears runs a free screen test in your browser — no app or download required.
How do I run a dead pixel test?
Open the Dead pixel test card — select colors, set cycle speed, press Start, and enter fullscreen. Arrow keys cycle colors; F toggles fullscreen.
How do I run a stuck pixel test?
Open the Dead pixel test, enable black in your color list, enter fullscreen, and inspect for bright dots. Any dot that stays lit on pure black is likely a stuck subpixel.
How do I test my LCD screen?
Use the dead pixel test for pixel defects, uniformity test for tint and bleed, and gradient or greyscale tests for banding. Each dedicated page has its own settings panel.
Is this a monitor test?
Yes. This is a free online monitor test covering dead pixels, stuck pixels, gamma ramps, contrast splits, brightness gradients, and motion patterns — the same checks used when reviewing a new display.
What is a display test?
A display test uses reference colors and patterns to inspect pixels, uniformity, motion, and refresh rate. TestMyGears splits each check into a dedicated page with its own customization panel.
How can I check my display?
Start at this test center, pick the check you need, adjust settings in the side panel, and use fullscreen for a clean test surface. The suggested workflow covers new-monitor QA in six ordered steps.
Is this the same as UFO Test?
TestMyGears offers similar dead pixel test and monitor test patterns to UFO Test — solid colors, gradients, and motion tests — but runs entirely in your browser with no separate download.
Can I test my phone or OLED screen?
Yes. Open the Dead pixel test on your phone, tap Start, and enter fullscreen. Pure black reveals stuck pixels on OLED; pure white reveals dark dead pixels.
