Display and Interface
At the heart of the E490 is a 2.2-inch TFT display, which supports up to 65,000 colors with a resolution of 176 x 220 pixels. Although modest by today’s standards, this display was adequate for its purposes, providing clear enough visuals for basic operations and multimedia. Additionally, it includes a secondary monochrome display on the exterior with a resolution of 128 x 32 pixels, which offers a unique seven-color backlight option for notifications, adding a small touch of personalization for users.
