Exact replacement panel

This 17.3 inch QHD display matches part number B173QTN01.5 for direct laptop screen replacement. It delivers a 2560x1440 resolution with a 120Hz refresh rate and a 40-pin video signal connector. The panel is non-touch and rated at 400 cd/m² brightness with a 700:1 contrast ratio.

Build integration

Installation requires a laptop chassis designed for a 17.3 inch 40-pin panel and a compatible display cable. The 120Hz refresh rate frees the GPU to drive smoother motion in supported titles without panel overdrive artefacts. No touch digitiser is present so the existing bezel and hinge assembly remain unchanged.

Capacity and headroom

Quad HD resolution at 120Hz handles fast-paced gaming and detailed creative work within the panel's native timing. The 700:1 contrast ratio limits deep-black performance in dark-room HDR content. Brightness tops out at 400 cd/m² so outdoor or high-ambient-light use may appear washed out.

Questions about this item

Will the 120 Hz panel throttle brightness or colour accuracy after hours of continuous use?

The panel is rated at 400 cd/m² brightness and a 700:1 contrast ratio; sustained output at 120 Hz stays within those specifications.

How much heat or fan noise does the 17.3 inch QHD screen add to a laptop running all day?

The display itself is a passive component — it produces no fan noise and its heat contribution is negligible compared with the CPU or GPU.

My laptop must already have which video connector to accept this 40-pin B173QTN01.5 replacement?

The screen requires a 40-pin video signal connector on the motherboard side; verify your current panel uses the same 40-pin interface before ordering.
