Compatible 17.3-inch FHD 144Hz panel

This 17.3-inch Full HD display operates at 1920x1080 resolution with a 144Hz refresh rate. It uses a 40-pin video signal connector and delivers 300 cd/m² brightness with an 800:1 contrast ratio. The panel is a non-touch model designed as a direct replacement for the B173HAN03.1 part number.

Ideal for repair, not for upgrades

Technicians repairing a laptop that originally shipped with this exact screen will find a matching fit. Buyers who want a touchscreen, a different resolution, a higher refresh rate, or a different pin layout should look at other panels.

40-pin connector dictates fit

The 40-pin video interface is the single specification that determines whether this panel will connect to the laptop’s motherboard. Verify the original screen uses the same 40-pin layout before ordering.

Questions about this item

How often will the B173HAN03.1 panel need replacement if the backlight degrades?

The LED backlight is rated for typical notebook lifespans; replacement is only needed if brightness drops well below the 300 cd/m² spec or the panel suffers physical damage.

What is the first limit you hit when gaming at 144Hz on this 1920x1080 screen for hours?

The 800:1 contrast ratio and 300 cd/m² brightness are fixed panel limits; sustained 144Hz operation does not introduce additional throttling or artefacts.

Does the 40-pin connector or the panel itself get hot or noisy during all-day use?

The B173HAN03.1 is a passive LCD module with no fan or moving parts; it runs silently and its surface temperature stays close to ambient under normal 144Hz operation.
