What this screen replaces

This 15.6 inch UHD 4K panel matches part number B156ZAN03.3 and uses a 40 pin video connector. It is built as a direct replacement for laptops that originally shipped with this exact model. The 3840x2160 resolution and 60 Hz refresh rate restore the factory display specification.

Fit and limitations

Buyers must verify that their device uses the B156ZAN03.3 part number and a 40 pin cable before ordering. This unit lacks touch functionality, so it will not work in touchscreen configurations. Laptops requiring a different connector count, resolution or refresh rate need a different panel.

The deciding specification

The 40 pin video signal connector determines compatibility. If the original screen uses a different pin count or signalling standard, this panel will not connect. Match the part number and connector exactly to avoid a mismatch.

Questions about this item

Will the 40-pin video connector on this 15.6-inch UHD panel match my laptop's motherboard socket?

The panel uses a 40-pin video signal connector; verify that your laptop's display cable and motherboard header are also 40-pin before ordering.

What is the installation step most people miss when fitting this B156ZAN03.3 screen?

After securing the panel, reconnect the 40-pin cable fully and lock the retaining latch; a loose latch causes flicker or no image.

Which component will likely need replacement first on a 600 cd/m², 60 Hz panel like this one?

The LED backlight ages over time; if brightness drops noticeably, the entire panel is typically replaced rather than the backlight alone.
