Compatible 17.3 inch replacement screen

This ATPAZDB panel matches part number B173HAN04.5 and fits laptops designed for that exact model. It delivers Full HD 1920x1080 resolution on a 17.3 inch diagonal without touch functionality. The 40 pin video connector aligns with the original hardware interface. Buyers needing a different pin count or touchscreen capability should look elsewhere.

Brightness and contrast in daily use

Rated brightness reaches 300 cd/m² with a contrast ratio of 800:1 for clear indoor viewing. The 144Hz refresh rate reduces motion blur during fast content without adding active cooling components. Power draw follows the laptop's existing display circuitry and produces no audible fan noise. Users requiring higher brightness for outdoor work will find this panel limited.

40 pin Full HD 144Hz specification

The single deciding factor is the 40 pin Full HD 1920x1080 144Hz interface that must match the laptop's display cable and controller. Verify the part number B173HAN04.5 on the original screen before ordering. Systems expecting a different connector, resolution or refresh rate will not accept this panel.

Questions about this item

How is the 40-pin connector seated during installation, and what step do people get wrong?

Align the 40-pin connector squarely with the socket and press straight in until it clicks; the common mistake is forcing it at an angle, which bends pins and causes no image or flickering.

What maintenance or replacement will the B173HAN04.5 need later?

No scheduled maintenance is required; if the backlight dims below the 300 cd/m² spec or the 144 Hz panel develops dead pixels, the whole screen assembly is replaced.

What limit appears first under sustained use?

The 300 cd/m² brightness ceiling is reached before thermal throttling; at maximum output the panel cannot exceed this luminance level.
