# G34WQCP is a wide-gamut VA panel (120% sRGB / 90% DCI-P3). Hyprland
# defaults to cm "srgb", i.e. no conversion, so sRGB content came out
# oversaturated. Clamp here rather than via the monitor's own sRGB OSD
# preset, which locks overdrive off — bad on VA. Panel is natively
# 8-bit, so no bitdepth override.
