AUO B156ZAN05.1 (15.6-inch UHD IPS Laptop Replacement Screen/3840x2160/40-pin eDP/Non-Touch/120Hz) Review
AUO B156ZAN05.1 15.6-inch UHD IPS laptop replacement screen, 3840x2160, 120Hz, 40-pin eDP, non-touch.
A newer, higher-refresh 4K UHD panel from AUO's B156ZAN05.x line, used in premium creator laptops that pair full 4K resolution with a 120Hz refresh rate rather than the standard 60Hz of older 4K panels.
Compatibility
The 120Hz 4K tier is newer and less common than the standard 60Hz B156ZAN0x panels — confirm your laptop actually shipped with a 120Hz 4K option before ordering, since a 60Hz cable/controller cannot drive this panel at full refresh.
