UFO Test: Multiple Framerates. Blur Busters UFO Motion Tests with ghosting test, 30fps vs 60fps, 120hz vs 144hz vs 240hz, PWM test, motion blur test, judder test, benchmarks, and more.
Ghosting Test. This test reveals ghosting, coronas, and overdrive artifacts. See LCD Motion Artifacts 101: Introduction and LCD Motion Artifacts: Overdrive for some examples of motion artifacts. In full screen mode, you can also drag to adjust the vertical position of the ghosting test.
Good full-readability (zero stroboscopic effect & no motion blur) with rapid occulsion effects, can require quadruple-digit display/VR refresh rates to match real-life in this test. Spinning LED clocks, LED bike wheel effects, and old mechanical TVs (Nipikow wheels) use the same persistence-of-vision technique (very high Hz for individual ...
UFO Test: Moving Picture Response Time (MPRT) Type of Display: This test is primarily designed for LCD displays (steady backlight, sample-and-hold displays). Instructions: Watch the UFO. Slowly adjust the "Pixel Per Frame" by 1 until background looks like a perfect checkerboard with the dark and light squares as exactly the same size as possible.
UFO Test: Motion Blur Caused by Display Persistence. Type of Display: This test shows motion blur on common LCD displays and most OLED displays. (See Why Do Some OLED Displays Have Motion Blur?) - If you are using ULMB or LightBoost motion blur reduction, temporarily turn it off for this test.
Panning Map Demo of Display Motion Blur. Demo of fast-panning map, showing that display motion blur can make text unreadable while scrolling or panning. A related demo is scrolling text, which is another common mainstream operation that is affected by display motion blur.
What Is The UFO Test? UFO test is the first-ever website that introduced the concept of testing the frames per second of a user's device. This helpful tool displays your device's frame rate, refresh rate, pixels per frame, and pixels per second.
UFO Test: Display Flicker Test for High Speed Cameras or Photodiode Oscilloscope. Test Mode: High Speed Camera — To compare display refresh behavior. This test needs a camera with a high-speed-video function (480fps+). An example recording is . This test is useful for capture display refreshing behaviour, including .
UFO Test: Blur Trail. Instructions: Track your eyes on the moving line. Look for artifacts. This is useful for checking for temporal elements of your display refresh. Faster moving line is better/easier for detecting artifacts.
This test simulates variable refresh rate technologies including G-SYNC, FreeSync, VESA AdaptiveSync, HDMI 2.1 VRR, and others. Variable refresh rates (VRR) eliminate stutters of fluctuating frame rates, by varying the refresh rate to exactly match a varying frame rate.
