HDMI stands as one of the dominant interfaces in the audiovisual product market. With the booming growth of the gaming market, the HDMI 2.1 specification has introduced the Variable Refresh Rate (VRR) feature specifically for gaming products. This feature allows users to reduce issues such as screen tearing and latency while playing games, and is widely supported by gaming consoles like PS5, Xbox, and high-end graphics cards from NVIDIA and AMD. It has become a crucial evaluation indicator for consumers when considering the purchase of gaming monitors.
Risks and Solutions for Input Lag in Gaming Monitors
Gaming monitors are considered high-end products, and their performance is highly valued by consumers. Allion has long-term collaborations with mainstream brands and ODMs in the monitor industry. Through our testing, we have observed instances where monitors equipped with VRR functionality still exhibit screen stuttering issues. While VRR is intended to enhance gaming performance, why does it introduce the risk of screen delay?
Upon analysis by Allion’s professional consulting team, we identified that early HDMI certifications for VRR testing involved the use of static patterns. As a result, these tests could only confirm whether the screen colors are normal and if there is any flickering, but they could not thoroughly verify the proper functioning of the VRR feature.
Static Testing Pattern
To address this issue, Allion can provide the latest VRR testing using dynamic patterns, coupled with high-speed cameras. This approach allows for a comprehensive examination to confirm the occurrence of screen tearing or delays. Allion’s complete and comprehensive VRR verification solution will help ensure that your gaming products deliver optimal performance.
Dynamic Testing Pattern
Pattern Description: The testing pattern consists of 4 squares, each moving from left to right.
Verification Method:
1. Record the test screen using a high-speed camera.
2. Playback the recorded video using a player frame by frame to inspect and confirm that each square moves sequentially without artifacts or delays.
