17.3" UHD 4K Replacement Panel

The ATPAZDB LQ173D1JW31B is a 17.3-inch laptop display panel with a 3840×2160 UHD 4K resolution. It uses a 40-pin video signal connector and operates at a 60Hz refresh rate. This new panel is built as a direct replacement for the LQ173D1JW31B model. It suits repair technicians or owners restoring a compatible notebook to its original screen specification.

Connector alignment and bezel fit

Installation requires matching the 40-pin connector exactly; a 30-pin cable will not seat and can damage the port. The panel is supplied without touch functionality, so the laptop’s digitiser layer must be absent or disconnected. Common issues arise when the bezel mounting points differ from the original chassis or when the backlight cable length is insufficient for the hinge routing.

60Hz refresh and 40-pin bandwidth limits

The 60Hz refresh rate caps motion smoothness at 60 frames per second, which is standard for productivity but limits high-frame-rate gaming. The 40-pin eDP interface carries the 3840×2160 signal at this rate without overhead for higher refresh modes. Brightness is rated at 300 cd/m² with a 1000:1 contrast ratio, so outdoor visibility and deep-black performance remain constrained by these panel specifications.
