Source4Reviewtechradar.com/televisions/lg-g5-reviewRead 5 October 2026Tested 65-inch. Filmmaker Mode HDR white-window measurements. 10% peak and 100% full-screen. Sustained durations and firmware are not stated. The reviewer identifies a 65-inch unit but does not state its regional suffix. No other size is inferred. Regional 65-inch performance equivalence is explicitly supported by the separate RTINGS Differences Between Sizes source.5Reviewrtings.com/tv/reviews/lg/g5-oledRead 5 October 2026Regional equivalence only. Differences Between Sizes states regional model suffixes have no performance difference. Tested US 77 OLED77G5WUA. Review explicitly applies performance to 65-inch, but no 77-inch measurements are stored here. The stored HDR numbers come exclusively from the separate TechRadar 65-inch test.27Measurementflatpanelshd.com/testscores.xmlRead 7 October 2026Added rows 3-10 from the original 65-inch FlatpanelsHD public record. Windows 1/2/5/10/25/50/75/100% are 2205/2213/2213/2206/1016/674/500/358 nits. Firmware 33.10.80. Review calls the calibrated mode ISF with ambient-light sensor off. Saved ISF Dark settings explicitly concern SDR, and a separate HDR preset label is not clarified. Per-point sustained duration is unstated. Existing TechRadar Filmmaker rows retained separately.29Reviewflatpanelshd.com/review.phpRead 7 October 2026Added rows 3-10 from the original 65-inch FlatpanelsHD public record.

Existing TechRadar Filmmaker rows retained separately.30Reviewrtings.com/tv/reviews/lg/g5-oledRead 7 October 2026Regional picture-performance equivalence only. Differences Between Sizes and Variants states results apply to 65 inches and regional suffixes have no difference in performance. Every newly added numerical measurement originates in an actual 65-inch review, not the tested 77-inch RTINGS unit. This statement does not establish UK tuner, radio, SoC or package identity.36Measurementflatpanelshd.com/js/scoreParsers_2022_003.jsRead 7 October 2026Public chart labels map the eight published PEAK window fields to 1/2/5/10/25/50/75/100 percent.
