 ## MIPI Display Interface
 
 The **STM32H747XI** has an internal 2D graphics accelerator with support for resolutions up to 1024x768, it also has the ability to encode and decode JPEG codec. This is what allows the **GIGA R1** to boast a 2 lane MIPI display interface. 
 
-This means that the **GIGA R1** is capable of driving a touch-display large enough to build a substantial user interface. The [LVGL](https://lvgl.io) library is a powerful tool to quickly build a responsive interface.
