Average response time (measured)
0.79ms6Reviewdisplayninja.com/benq-ex271uz-reviewRead 5 October 2026Exact EX271UZ 240 Hz response chart averages initial transition time 0.79 ms with fixed RGB 5 tolerance, OSRTT Overdrive Off metadata and V022 firmware. Complete 1.01 ms and perceived 1.05 ms are different endpoints. The reviewer explicitly attributes slower transitions and overshoot to OSRTT instrument limitations. Maker GtG 0.03 ms has no published endpoint or settings. Matching model, refresh rate and test conditions were rechecked because the values differ substantially. The shared OSRTT test paragraph explicitly says calibrated and warmed up. Chart metadata FPS limit 1000 and V-Sync True are preserved.

Current Japanese body specs match US, while older launch chassis/power figures conflict and are not transferred. Canonical EU fiche separately states supplier minimum guarantee 2 years. The stored 3 years retains the explicitly documented Japan launch policy and does not promise 3 years in every market.11EU energy label (EPREL)eprel.ec.europa.eu/fiches/electronicdisplays/Fiche_2448020_EN.pdfRead 5 October 2026EU fiche gives minimum supplier guarantee 2 years, versus Japan launch policy 3 years.
