Direct-fit 17.3-inch QHD panel

This 17.3-inch replacement screen matches part number B173QTN01.1 and delivers a 2560x1440 Quad HD resolution at 120 Hz. It uses a 40-pin video connector and is built without touch functionality. The panel is intended for technicians or owners repairing a compatible laptop chassis.

400 cd/m² brightness and 700:1 contrast

Rated brightness reaches 400 cd/m² with a 700:1 contrast ratio for clear indoor viewing. Power draw and thermal output follow the laptop's original panel design, so cooling and battery behaviour remain unchanged. No additional fan noise or heat is introduced by the swap.

No extra accessories or software included

The shipment contains only the display panel itself; no brackets, cables, tools or driver discs are bundled. Installation relies on the existing 40-pin harness and mounting points already present in the device. No calibration software or firmware updates are supplied or required.

Questions about this item

How do I install the B173QTN01.1 40-pin connector without bending pins?

Power off the laptop and disconnect the battery. Align the 40-pin video connector squarely with the socket, press straight in until it clicks, then secure the panel with the original screws. The step most people rush is checking pin alignment before applying pressure.

What maintenance or replacement will the B173QTN01.1 need over time?

The panel has no user-serviceable parts. Keep the surface clean with a microfibre cloth and avoid pressure on the bezel. If brightness drops below the rated 400 cd/m² or the 120 Hz refresh becomes unstable, the entire screen assembly is replaced as a unit.

What limit appears first on the B173QTN01.1 during long gaming sessions?

The 700:1 contrast ratio is the first constraint you notice in dark scenes during extended use; black levels lift and shadow detail compresses before the 400 cd/m² brightness or 120 Hz refresh rate become limiting factors.
