Welcome to FrameRateTest.org! Test your screen's Frames Per Second (FPS) to check fluidity, verify advertised refresh rates, and assess whether your display is ready for movies, gaming, or competitive play.
To run an FPS test:
Warning: Measured FPS and resolution are approximations — browsers and devices each impose their own limits.
Watch the rectangles and note any choppiness. Try changing Speed, Canvas FPS, Opacity, and Colors to see how each affects motion. If your measured FPS stays below your monitor's refresh rate (often 60Hz), your browser or hardware may be the bottleneck. High resolution, large rectangles, and transparency can all reduce FPS — watch the Tool FPS ratio to see if the test is hitting its own targets.

Frame rate is the number of images ("frames") shown on screen each second, measured in frames per second (FPS). A 60 FPS display shows 60 images per second, creating the illusion of motion — like flipping through a stack of photos quickly. Higher frame rates mean smoother motion, which matters especially for action movies and competitive gaming. See our article on what frame rate is for more.
FPS stands for "Frames Per Second" — how many images are shown each second. More FPS generally means smoother motion: 60 FPS looks more fluid than 30 FPS.
Two rectangles move left to right across your screen. You can adjust their color, spacing, height, width, and speed, and lower the test's update rate to better appreciate your screen's fluidity at full speed. The tool also displays your current resolution, measured FPS, and the test's own refresh rate based on your settings.
FrameRateTest.org and its affiliate websites offer you other screen tests to make sure your display works well. You may find them below.
DeadPixelTest.org helps you check your screen for any dead, bad, or stuck pixels that might impede your media, work, or gaming experience. By running this test, you can make sure that your monitor is flawless and has no odd dots that can reveal annoying. You will be able to display colours on the full width of your screen in order to check for any dead pixels or stuck pixels. DeadPixelTest.org also provides a dead pixel fixer that might help you revive your bad pixels.
With BacklightBleedTest.org, you can check for something called backlight bleed. This usually happens on LCD screens when the light from the back of the screen leaks around the edges, causing bright spots or patches, especially when the screen is showing dark images. This test displays a black screen so you can easily spot any uneven lighting. It's a quick way to see if your monitor or TV has this common issue.
DeadPixelTest.org's screen resolution test is a simple tool to find out the resolution of your screen. Your screen's resolution is the number of pixels it can show, like 1920x1080 (Full HD) or 3840x2160 (4K). Knowing your resolution is important for getting the best picture quality and making sure your computer or other devices are set up correctly. This test instantly tells you your screen's native resolution and many other useful information about your display.
You can use DeadPixelTest.org's screen contrast test to see how well your screen shows the difference between black and white. Good contrast means you can see all the details in both very dark and very bright parts of an image at the same time. This test shows a pattern of black and white gradients to help you adjust your screen's contrast settings for the best possible image quality, so you don't miss any details
