This guide will walk you through the basics of customizing the LCD screen on your Lenovo IX4-300d NAS device. By default, the display shows only limited information, but with a bit of creativity and some simple scripting, you can extend its functionality to show more relevant and useful data. This guide serves as a starting point — once you’re familiar with the process, the possibilities for customization are wide open.
Instead of displaying text directly, we’ll be working with BMP image files to show custom content on the LCD. At the time of writing, there is no known method to write plain strings directly to the screen, so images are the way to go. Whether you want to show system stats, network info, or even fun visuals, this guide will help you get started with building and displaying your own custom BMP images.
