It contains dozens of tests including explanatory science (eye tracking, persistence of vision, black frames, variable refresh) and tests designed for display analysis (pursuit camera test, scanout test), and many others selectable tests.
What’s very special about TestUFO? It uses a default motion speed of 960 pixels per second.
960 Pixels/Sec Is Closest Number To 1000 Divisible By 60, 120 and 240 Hz
There was a need for a motion speed divisible by futuristic refresh rates long before they came on the market. TestUFO launched in 2013, well before the first 240Hz monitors and the 480Hz experimental display! We wanted to use something that easily compares math to pictures, and pictures to math.
1ms translates to 1 pixel per 1000 pixels/second — the simplified Blur Busters Law formula.
960 Pixels/Sec Is Faster Than Many Outdated TV Benchmarks
A very old, formerly common motion resolution benchmark for televisions, monitors and displays was a test pattern used by plasma television manufacturers, FPD Benchmark Software (Blu-Ray Chapter 31). As I used to work in the home theater industry, old television engineers and old home theater magazines were using outdated “lines of motion resolution” methods that often varied with motion speed. Flaws of FPD are explained here.
To avoid this outdated test, TestUFO needed to come up with universal motion benchmarking that stayed consistent regardless of motion speed in the retina resolution race (4K, 8K+) and retina refresh rate race (120Hz, 240Hz+).
960 Pixels/Sec Is More Representative Of Fast Video Game Motion Speeds
Old benchmarks for televisions used very slow scrolling test patterns. Sports & gaming use faster motion than these benchmarks. Motion in esports competitive games such as Fortnite, Counterstrike: GO, and other games can go thousands of pixels per second, creating a massive amount of display motion blur.
960 Pixels/Sec Is Not Too Fast To Eye-Track
The speed of 960 pixels per second means an object takes 2 seconds to cross a 1920×1080 display. We needed a fast motion speed that was still possible to eye-track. We are very familiar with eye-tracking motion blur which is an important component of the science of display motion blur,
First, look at the stationary UFO, then look at the moving UFO. On most LCD and OLED displays, you are witnessing eye-tracking-based motion blur with the moving UFO. This is blurring from persistence (MPRT).
960 Pixels/Sec Is Easy To Double And Quadruple
The tidy 960 number is also very easy to memorize for testing faster motion speeds.
- 960 times 2 equals 1920, the horizontal resolution of 1080p displays.
- 960 times 4 equals 3840, the horizontal resolution of 4K displays.
- 960 times 8 equals 7680, the horizontal resolution of 8K displays.
Our UFO Trademark Is A Deliberate Test Pattern Easter Egg!
Did you know that our Blur Busters UFO logo was intentionally designed as a test pattern?
- At 16 pixels of motion blur, UFO landing legs are very blurry.
- At 8 pixels of motion blur, UFO landing legs are seen but saucer details are very blurry.
- At 4 pixels of motion blur, UFO saucer details are seen but can’t count alien eyes.
- At 2 pixels of motion blur, UFO alien 3 eyes can be counted but are still blurry.
- At 1 pixel of motion blur, UFO alien 3 eyes have clear eye pupils & eye whites.
Note: These images assumes insignificant GtG pixel response that is only a tiny percentage of a refresh cycle. See Pixel Response FAQ: GtG versus MPRT for more information how pixel response can degrade motion blur further.
960 Pixels/Sec Bridges Popular Science & Advanced Research
We understand display manufacturers have to use photodiode oscilloscopes and other complex measuring equipment, and to use VESA measurement standards that accommodates noise margins. However, many people need something easy to explain in images and video as a bridge between familiarity (looking at pictures) and what researchers and scientists do (using measuring equipment).
1ms of persistence = 1 pixel of motion blur per 1000 pixels/second.
Conclusion: 960 Pixels/Sec is a Universal Display Motion Test Speed
Test UFO Motion Tests paved the industry standard display motion speed. Many researchers, companies, reviewers now use variants of this motion speed, thanks to TestUFO being used by millions of visitors worldwide.
