Refresh Rate Test Online
A refresh-rate visual test helps you confirm that motion looks smoother after switching to a higher display mode.
Live screen test
Start with the real patterns.
Check visual refresh rhythm and frame pacing.
What it checks
Use this test when you need a clear visual answer.
Refresh Rate Test is built for quick inspection, not lab measurement. It gives you controlled browser patterns so you can decide whether the screen needs setup, retesting, or warranty attention.
Smoothness changes
Wrong OS refresh setting
Frame pacing irregularity
Result guide
How to read the refresh rate result
Start with the refresh sweep pattern, then switch to adjacent patterns before making a decision. A real display problem usually stays in the same area when the pattern changes. A reflection, viewing angle shift, browser zoom issue, or temporary image setting often changes when you move your head, adjust brightness, or repeat the test after a restart.
Smoothness changes
Use this page to isolate smoothness changes under controlled screen patterns. Scan the center, edges, and corners, then confirm the same area with a second pattern before you treat it as a panel issue.
Wrong OS refresh setting
Use this page to isolate wrong os refresh setting under controlled screen patterns. Scan the center, edges, and corners, then confirm the same area with a second pattern before you treat it as a panel issue.
Frame pacing irregularity
Use this page to isolate frame pacing irregularity under controlled screen patterns. Scan the center, edges, and corners, then confirm the same area with a second pattern before you treat it as a panel issue.
Workflow
How to use the refresh rate test
Set the desired refresh rate in the operating system or GPU control panel.
Open the moving pattern fullscreen and compare smoothness with your previous setting.
If motion still looks like 60 Hz, recheck the cable, display input, and OS setting.
Use cases
Where this screen test is most useful
New gaming monitor
Confirm the panel is not accidentally running at 60 Hz.
Cable troubleshooting
A wrong cable or adapter can limit available refresh rates.
Laptop external display
Check whether the external monitor is using the expected mode.
Reading the result
Practical tips before you decide
Browser tests are visual
They show smoothness differences but do not replace OS-level refresh readouts.
Use fullscreen
Fullscreen reduces distractions and makes motion judder easier to spot.
Check the display menu
Many monitors show the active resolution and refresh rate in their OSD.
Device setup
Use the same screen test across real viewing setups
The refresh rate test works best when the test matches the way you actually use the display. Keep the room lighting, brightness, scaling, and viewing distance close to normal, then repeat the pattern only after a setting change. This keeps the result practical instead of turning the page into a lab claim.
Desktop and laptop monitors
Use native resolution, 100 percent browser zoom, and the monitor picture mode you normally use. If you change brightness, contrast, overdrive, or color temperature, repeat the refresh rate pass before comparing results.
TVs, projectors, and large panels
Step back to your real viewing distance after a close inspection. Large screens can exaggerate small edge, glow, focus, or processing issues, so confirm anything suspicious with normal video, games, or desktop content.
Phones and tablets
Rotate the device if the browser supports it, clean the glass, and reduce reflections before judging the result. Some mobile browsers limit fullscreen behavior, but the same pattern sequence still helps with quick display checks.

Response Time Test
Moving blocks and high-contrast edges make slow transitions, dark smearing, and overshoot easier to see.
Ghosting Test
Ghosting appears as visible trails behind moving objects. This page gives you a quick motion target for tuning the display.
Monitor Test Patterns
Test patterns combine grids, lines, gradients, and color blocks so you can check geometry and image processing quickly.
Contrast Test
Use stepped tone patterns to see whether your display keeps dark and bright details separate.
FAQ
Refresh Rate Test questions
These answers match the visible test on this page and avoid warranty or measurement claims that depend on your specific display.
Can a browser measure my exact refresh rate?
Browser animation timing can estimate motion behavior, but the most reliable setting is in your OS or monitor OSD.
Why is my 144 Hz monitor stuck at 60 Hz?
Common causes include OS settings, cable limits, adapter limits, or using the wrong monitor input.
Does fullscreen matter?
Fullscreen helps you focus on motion and reduces interface interruptions.
Should I use this with VRR enabled?
You can, but fixed refresh comparisons are easier when you know the exact display mode.
Can I use the refresh rate test on more than one device?
Yes. Open the same page on each monitor, laptop, phone, tablet, TV, or projector, then compare the refresh rate result under similar brightness and room lighting. Device browsers can handle fullscreen differently, but the visual patterns are still useful for a practical check.
Does this online refresh rate test replace professional calibration?
No. This page is a browser-based visual test for finding obvious display problems and setup issues. For color-critical work, brightness targets, or measured calibration, use a hardware colorimeter or professional display workflow after the visual pass.
How to Check a Monitor for Dead Pixels
A reliable dead pixel check uses fullscreen solid colors, steady lighting, and a repeatable inspection path. The goal is to separate real panel defects from dust, reflections, scaling artifacts, and temporary cable issues.
How to Test a New Monitor
A new monitor should be tested before you mount it, remove packaging, or let the return window pass. Start with panel defects, then verify uniformity, tone, text clarity, refresh rate, and real content.
Monitor Calibration Guide
Browser tests can help you set a monitor to a sensible baseline and spot obvious problems. They do not replace a colorimeter, but they make brightness, contrast, gamma, sharpness, and banding easier to judge before hardware calibration.
