Multi-Touch Screen Test
Check how many simultaneous touch points a compatible touchscreen reports and visualize finger positions, movement, and release events.
Browser touch events are displayed as colored points so you can see simultaneous contacts and basic tracking continuity. Use the full test area and add fingers one at a time without resting your palm or triggering browser navigation gestures.
What does this test measure?
Browser touch events are displayed as colored points so you can see simultaneous contacts and basic tracking continuity.
Why is this test important?
Check how many simultaneous touch points a compatible touchscreen reports and visualize finger positions, movement, and release events.
How do you run the test?
Use the full test area and add fingers one at a time without resting your palm or triggering browser navigation gestures.
How should results be interpreted?
A missed point can result from hardware limits, palm rejection, browser gestures, operating-system settings, screen contamination, or a faulty region.
Normal and problematic results
A missed point can result from hardware limits, palm rejection, browser gestures, operating-system settings, screen contamination, or a faulty region.
Technical limitations
The test cannot calibrate the digitizer, measure pressure unless exposed, or override operating-system and browser gesture reservations.
Why can the score decrease?
Unstable measurements, denied permissions, unsupported browser APIs, background load, power saving, or an incomplete test can affect the result. When a score changes, the result screen explains the reason.
What should you do if a problem is found?
Clean the screen, remove interfering accessories, disable conflicting gestures temporarily, rotate the device, and compare another application.

Frequently Asked Questions
How many fingers should my screen detect at once?
Most modern touchscreens track ten simultaneous points, though some budget panels stop at five or two. Place fingers down one at a time and watch the count to find the real limit of your device.
Why do some touch points disappear when I add another finger?
That is the panel reaching its tracking limit, and it is a hardware characteristic rather than a fault. Points vanishing well below the expected count can also come from a screen protector or moisture on the glass.
Can I run this on a laptop without a touchscreen?
The test needs a touch-capable display. A touchpad reports gestures in a different way and will not register here, so use the touchpad test instead.
