Direct-fit 4K replacement panel

This 15.6 inch display carries the exact part number B156ZAN03.4 and is built for notebooks that originally shipped with that panel. It delivers UHD 4K 3840x2160 resolution at 60Hz with a non-touch surface and a 40 pin video connector. The unit is supplied new and matches the factory brightness of 300 cd/m² and contrast of 1200:1.

Ideal for exact part-number swaps

Technicians and owners replacing a cracked or failed B156ZAN03.4 screen can install this unit without adapter cables or firmware changes. Buyers whose laptop uses a different connector pin count, a touch-enabled assembly, or a lower native resolution should source the panel that matches their original specifications.

40 pin connector decides fit

The video signal interface is a 40 pin layout; only laptops wired for that exact connector will accept the panel. Verify the original screen part number and pin count before ordering.

Questions about this item

Does the 60 Hz refresh rate limit motion clarity during long gaming or video sessions?

The panel refreshes at 60 Hz, so fast motion may show some blur compared with higher-rate displays, but the rate is fixed and does not change with temperature or usage time.

How much heat and power does the 300 cd/m² backlight generate when the screen runs all day?

At 300 cd/m² brightness the backlight draws modest power and produces low heat; the panel has no active cooling, so it stays warm but not hot during continuous operation.

Will this 40-pin UHD panel work with my laptop's existing video cable and mounting brackets?

The screen uses a 40-pin video signal connector and matches the B156ZAN03.4 form factor; you need a laptop that accepts that exact pin-out and physical size.
