Our Motion Score and Tests
How motion looks on a TV is a complex subject. We define this category as anything related to moving pictures. This includes motion blur and different kind of judder issues. A TV performing well in this category should display frames smoothly, yet clearly.
Our response time test evaluates TVs for how blurry movement will look on the screen. Given the amount of movement sports have back and forth across the screen, a TV’s amount of motion blur is a big factor in how good sports and video games are going to look.
Most people shouldn’t have problems unless a TV has a particularly high amount of motion blur, but there is a fair number of people who are somewhat sensitive to seeing blur, and for whom this test takes on a bit more importance. For that reason, we consider this test very important for evaluating a TV for sports or video games.
The image flicker test focuses on the type of blur caused by eye tracking over a static frame. It is most significant when following objects on the screen, such as for sports or video games. A lack of flicker causes smoother looking movement with more blur, but flicker can also be used to improve fast motion. As a result, this test is more useful to determine a TVs performance for sports or video games.
This set of tests verifies whether a TV is able to play 24 fps movies without judder. If you watch movies and are bothered by this kind of judder, these results will be pretty important. If you don’t watch movies or aren’t bothered by this kind of judder, don’t worry about these.
These tests verify whether a TV is able to use motion interpolation to smooth movement. If you like high frame rates and want all videos to have that smoothed-over look, you should make sure your TV can interpolate the media that you watch. If you hate the ‘soap opera effect,’ or just don’t care about making video extra smooth, don’t worry about these tests.
What is not included
A few elements that you might care about are not included in this score:
- Screen tearing: Screen tearing issues are related to a frame timing mismatch between the source and the screen. We don’t know of any TVs with a V-sync option to correct this sort of problem.
- Judder caused by poor USB playback by the TV
- Frame skipping caused by motion interpolation
- Frame skipping caused by poor playback by the TV’s apps
