Display
The U450’s display introduces a 2.1-inch TFT screen that supports 256K colors. While not particularly large by today's standards, the display’s 176 x 220 pixel resolution with a pixel density of approximately 134 ppi provides adequate clarity for the basic functions it was designed to perform. However, the screen-to-body ratio of around 24.2% indicates a more utilitarian approach to display design, with practical considerations taking precedence over aesthetics.
