Lunar Light belongs to AW2521HFL and is not a second HF colour.","pixel_pitch_mm":"Own horizontal pitch 0.2832 mm. Vertical 0.2802 mm is distinct and does not share this scalar. Explicit active dimensions agree at maker precision.","srgb_coverage_pct":"Own manual typical 99% sRGB coverage. CIE reference is unstated.","response_time_gtg_ms":"Own fastest maker GtG claim 1 ms in Extreme, which can cause visible artifacts. Super Fast 2 ms and Fast 4 ms are separate.","refresh_rate_modes":"Own Resolution Specifications expressly gives maximum native 1920 x 1080 at 240 Hz for DP 1.2 and HDMI 2.0, not just timing presets.

Display Manager compatibility is separately named and its exact guide proves direct monitor image controls.","rgb_lighting":"Own AlienFX lighting zones allow RGB colour codes and multiple colours, not only an ordinary power LED.","dimensions_with_stand_mm":"Own width and depth are direct. Height endpoints are omitted because published extended/compressed difference 104.87 mm differs from the stated 130 mm travel. Neck/body pose scope is unresolved.","stand_footprint_mm":"Own supplied stand width 465.3 mm and depth 251.92 mm. No inferred rectangular area.","weight_with_stand_kg":"Own physical table with stand assembly and cables.","weight_without_stand_kg":"Exact A03 December 2020 manual publishes 4.15 kg without stand or cables.
