Ideal for repairing a compatible laptop

This screen suits technicians or owners replacing a damaged LQ125T1JW02B panel with an identical specification. It is not suitable for laptops that require a different pin count, connector placement, or touch functionality. Buyers needing a higher refresh rate, different resolution, or alternative form factor should look elsewhere.

40-pin connector and 3840x2160 resolution

The single specification that determines compatibility is the 40-pin video signal connector paired with the 3840x2160 UHD 4K resolution. The replacement laptop must accept this exact pin layout and signal format. Verify the original screen part number matches LQ125T1JW02B before purchasing.

Questions about this item

Does the 40-pin connector on the LQ125T1JW02B ever need reseating or replacement after fitting?

The 40-pin video signal connector is a fixed interface; once the panel is installed correctly it does not require periodic reseating or connector replacement.

What is the first limit reached when the LQ125T1JW02B runs at 3840x2160 continuously?

The panel operates at a fixed 60 Hz refresh rate, so sustained use is bounded by that 60 Hz ceiling rather than thermal or power throttling.

How much heat and power does the 12.5-inch 4K screen produce at its rated 340 cd/m² brightness?

At 340 cd/m² brightness the display draws only the power needed for the backlight and driver circuitry, generating minimal heat with no audible noise.
