AdaptiveSync v1.0
Performance Criteria
This information pertains to AdaptiveSync version 1.0. For current version information, see AdaptiveSync 1.1 Performance Criteria
The following table summarizes the Adaptive-Sync Display specifications that vary across the logo performance tiers.
Test | AdaptiveSync | MediaSync |
---|---|---|
Adaptive-Sync operation maximum refresh rate range | ≥ 144 Hz | ≥ 60 Hz |
Adaptive-Sync operation minimum refresh rate range | ≤ 60 Hz | ≤ 48 Hz |
Testing that Overdrive factory-default setting does not result in excessive Overshoot/Undershoot | ≤ 20% overshoot and ≤ 15% undershoot (on any of the 16 test cases) | ≤ 20% overshoot and ≤ 15% undershoot (on any of the 16 test cases) |
Limit in average of the 20 G2G tests from a 5 × 5 matrix with factory-default overdrive | ≤ 5-ms average over the 20 tests | N/A |
Flicker(max) on low-variability refresh rate tests | -50 dB | -50 dB |
Flicker(max) with high-variability refresh rate tests | -50 dB | Test is not performed as a logo performance tier mandate |
If SuccessiveFrameDuration IncreaseTolerance is present, minimum duration for variable | 8.5 ms | 1 ms |
If SuccessiveFrameDuration DecreaseTolerance is present, minimum duration for variable | 9.75 ms | 1 ms |
Video frame-to-frame jitter duration for 23.976- to 60-Hz video frame rates | ±0.5 ms | ±0.5 ms |
In addition to the logo-specific tests above, all qualifying devices must meet the following specifications that apply to all logo performance tiers:
Test | Requirement | Units |
---|---|---|
Video Frame Drop Tolerance between minimum and maximum refresh rates reported to the OS | 0 | Dropped Video Frames |
The 10 static frequency video frame rates that are to be supported within the Jitter specification limit, potentially by using display-side or GPU video frame duplication (e.g., frame-doubling, frame-tripling, etc.) | 23.976 24 25 29.97 30 47.952 48 50 59.94 60 | Hz, Locked Video Frame Rates |
