14.0-inch 2560x1600 replacement panel

This 14.0-inch LCD panel replaces the display in Dell 14 Plus models DB14250 and DB14255. It matches the NE140QDM-N42 part number and delivers a 2560x1600 resolution at 90Hz. The screen is non-touch and uses a 40-pin connector. It is intended for owners of those specific Dell laptops needing a direct swap.

40-pin connector and professional install

The panel connects via a 40-pin interface compatible with the listed Dell models. Installation requires disconnecting the power adapter and battery cable before fitting the screen. No instructions are included, so professional fitting is advised. The package contains only the LCD panel, not a complete laptop assembly.

LCD-only package and verification steps

Only the bare LCD screen is supplied; no bezel, hinges or cables are included. Buyers must verify the part number on the original screen before ordering. If the wrong model is received, the packaging should remain sealed for return. The supplier requests a photo of the old screen's back label if compatibility is uncertain.

Questions about this item

Will the 90 Hz refresh rate hold steady during long sessions or does it throttle?

The panel is rated at 90 Hz and has no thermal throttling mechanism; sustained output depends on the laptop's own GPU and cooling.

How warm does the NE140QDM-N42 get and does the backlight whine after hours of use?

The screen is a passive LCD component — it generates negligible heat and has no moving parts, so audible coil whine is not a characteristic of this panel.

Which cables or adapters must already be in my Dell 14 Plus DB14250 for this 40-pin 2560x1600 display to work?

Your laptop must provide a 40-pin eDP cable that matches the NE140QDM-N42 pin-out; no extra adapter or converter is included with the screen.
