15.6 inch UHD 4K replacement panel

This 15.6 inch display panel replaces a damaged or faulty B156ZAN04.2 screen. It delivers UHD 4K resolution at 3840x2160 with a 60Hz refresh rate. The panel uses a 40-pin video signal connector and operates without touch functionality. Brightness reaches 500 cd/m² with a 1200:1 contrast ratio.

Compatibility and use-case fit

The screen fits laptops designed for the exact B156ZAN04.2 part number and 40-pin interface. It suits repair technicians and owners restoring original 4K clarity. Buyers whose devices use a different connector, a lower native resolution, or a touch-enabled assembly should look elsewhere.

Deciding specification: 40-pin UHD 4K panel

The single specification that determines fit is the 40-pin UHD 4K 3840x2160 configuration matched to part number B156ZAN04.2. Verify the original screen carries this exact part number and pin count before ordering. No other connector or resolution variant will work with this panel.

Questions about this item

Does the 60 Hz refresh rate become a visible limit during sustained 4K gaming or video editing?

The panel is specified at 60 Hz, so motion updates are capped at that rate regardless of workload.

How much heat or power draw should I expect from the 500 cd/m² backlight during all-day use?

The screen runs at 500 cd/m² brightness with a 1200:1 contrast ratio and no touch layer, keeping power demand typical for a 15.6 inch 4K panel.

Will this 40-pin connector work with my laptop's existing eDP cable and mounting brackets?

The display uses a 40-pin video signal connector and matches the B156ZAN04.2 form factor, so it fits the original cable and mounting points.
