Display
Equipped with a 6.1-inch IPS LCD screen, the LG K40S provides a screen-to-body ratio of approximately 80.4%, which is respectable for its class. The 720 x 1520 resolution delivers a decent 276 PPI pixel density, supporting satisfactory visual clarity and color accuracy. While it may not rival high-end devices in terms of display sharpness and vibrancy, it certainly accomplishes its task for everyday use, with adequate brightness and viewing angles.
