14 inch QHD IPS replacement panel

This is a 14 inch QHD IPS laptop replacement screen with a 2560x1440 resolution, 60Hz refresh rate and 40 pin video connector. It delivers 300 cd/m² brightness and an 800:1 contrast ratio in a non-touch panel. The part number B140QAN02.3 identifies the exact panel for direct swap installation.

Who this fits and who it does not

It suits owners of laptops that originally shipped with the B140QAN02.3 panel and need a like-for-like replacement. Buyers whose devices require a touchscreen layer, a different pin count or a higher refresh rate should look elsewhere.

The deciding specification

The 40 pin connector and 14 inch 2560x1440 IPS specification are the critical match points; the replacement will only work if the original screen uses the identical 40 pin interface and panel dimensions.
