Browser-fill is only a preview. Use its visible exit button, Esc, or hold the chart for 1.6 seconds to return.

Chart settings are also saved automatically when browser storage is available. Offline shell is not confirmed yet. Native-video packs must be saved separately in Downloads.

Fullscreen: Esc to exit. Arrow keys change the chart; B toggles blackout; L toggles labels. Hold still on the chart for 1.6 seconds to exit without a keyboard. Browser-fill preview is explicitly not fullscreen.

A projector test chart, wherever you work

ProjectorTest is a free browser tool for setting up projectors, displays and video systems. Start a fullscreen geometry chart on a computer, or choose iPhone HDMI for a native 1920 × 1080 reference video. No account or app installation is needed.

What can I test?

Use grids, circles and corner markers for alignment and keystone checks. Focus, pixel, grayscale, color-bar and solid-field patterns help reveal blur, scaling, clipping and unevenness. Safe-area guides and aspect, throw, raster-fit and frame-delay calculators support setup planning.

How do I check true 16:9?

Select a 1920 × 1080 source, disable projector overscan and use an aspect-preserving mode. Show all four corners, check that the circle is round, then measure the border: height should equal width × 9 ÷ 16. Use Verify to record your physical checks.

Does a 1080p chart prove 1080p HDMI?

No. The source dimensions are exact, but your browser, operating system, adapter or projector may scale the picture. Confirm 1920 × 1080 progressive in the projector’s input-information menu. iPhone video routing varies by hardware; the HDMI troubleshooting lab helps compare playback paths.

Are the colors broadcast-certified?

Browser color bars and Rec.709 code calculations are reference tools, not measured signal certification. Color management, range conversion and display settings can alter the output. Use a signal analyzer or scopes when broadcast compliance matters.

Settings and verification notes stay on your device. Offline charts need the app shell to finish caching; iPhone video packs must be saved separately.
