So, following the Y40 review, I’ve wanted to check if it’s as easy to replace the Y40 display as for the Y50. The Y40 1080p default display is mediocre at best. True, it’s an 1080p display, but it’s of rather low quality – barely 60% of sRGB color coverage, bad accuracy and contrast and average at best viewing angles. And we are talking a $800-$1000 laptop here.
I’ve ordered the AUO B140HAN01.2 1080p eDP display (get from laptopscreen, Amazon, eBay) which is an AHVA display. This B140HAN variant is simply the only one I could find for a relatively reasonable price which is also good enough.
Replacing the display was quite easy. You simply pull out the front bezel of the Y40 display with your fingers, then unscrew four screws that hold the panel itself. At this point pull it softly. Check the hardware maintenance manual.
The images are a little bit dark, but you can see that the colors remains good overall.
Some measurements with the DataColor Spyder4Elite:
Subjectively, the difference compared to the default panel is huge. Games, specifically WoT, look much much better with details and terrain looking much more vivid. Reading is easier, viewing angles are ofcourse much better and very good by themselves and watching movies is also much more fun. I would definitely recommend replacing the display.
