The certification framework, introduced at ChinaJoy in July 2026, addresses a growing industry issue where overclocked displays often fail to maintain visual stability during intense use. By mandating a "same mode, full-system testing" principle, TÜV Rheinland excludes overclocking from its evaluations. Instead, it assigns a Gaming Performance Index (GPI) based on fourteen indicators across motion performance, image quality, and visual comfort. The process incorporates dynamic visual acuity assessments and eye-tracking analysis to quantify the subjective experience of gamers.

Lenovo saw 16 of its Legion monitors achieve ratings between three and five stars, covering everything from entry-level gear to flagship models like the Legion Pro 32UD-10. Meanwhile, four models from the Shenzhen-based brand ANTGAMER—the ANT25ASF, ANT255TQ, ANT275TQ, and ANT272TUE—secured the top-tier five-star rating. Jay Yang, a Global Senior Vice President at TÜV Rheinland, noted that the initiative aims to shift industry competition away from marketing-driven metrics toward performance validated by real-world usage scenarios.
