17.3-inch QHD replacement panel

The ATPAZDB B173QTN01.2 is a new 17.3-inch laptop replacement screen built to match the original B173QTN01.2 part number. It delivers a Quad HD resolution of 2560x1440 for users who need a direct swap without adapter boards or firmware changes.

40-pin connector and 120 Hz refresh

The panel uses a 40-pin video signal connector, so it only fits laptops wired for that exact pinout and signalling. Its 120 Hz refresh rate is fixed by the panel hardware; systems limited to 60 Hz output will not benefit from the higher rate, and the connector cannot be converted to 30-pin or other standards.

400 cd/m² brightness and 700:1 contrast

At 400 cd/m² the display suits indoor productivity and media viewing, but it lacks the luminance headroom for bright outdoor or direct-sunlight use. The 700:1 contrast ratio provides adequate separation for general tasks, though dark-room content will show limited black depth compared to higher-contrast panels.

Questions about this item

Should I choose the 40-pin version or a different connector for my B173QTN01.2 replacement?

This panel uses a 40-pin video signal connector and is built specifically for the B173QTN01.2 part number, so it matches the original connector without adapters.

How does the 120 Hz refresh rate and 2560×1440 resolution feel in daily use?

The 120 Hz refresh rate at 2560×1440 gives noticeably smoother motion in games and scrolling compared to standard 60 Hz panels, while the QHD pixel density keeps text sharp on the 17.3 inch display.

What does the 40-pin interface cap in practice for this screen?

The 40-pin eDP connection carries the full 2560×1440 signal at 120 Hz, supporting the panel's 400 cd/m² brightness and 700:1 contrast without bandwidth limitation.
