Exact-fit 4K 15.6-inch panel

This replacement screen matches the LP156UD3(SP)(B3) part number and fits laptops that specify that exact panel. It delivers a 3840x2160 UHD image on a 15.6-inch diagonal. The unit is supplied new and without touch functionality.

Straightforward 40-pin swap

Installation uses the native 40-pin video connector, so no adapter or converter is required. The panel mounts in the standard 15.6-inch frame used by the original part. Common issues arise when the laptop's bezel or hinge brackets differ from the reference design, or when the display cable routing is tighter than expected.

Ideal for exact-part repairs, not for upgrades

This screen suits repair technicians and owners who have confirmed the LP156UD3(SP)(B3) part number on their existing panel. It does not suit buyers seeking a higher refresh rate, touch input, a different connector count or a panel for another model series.
