7.1 ეკრანის ოპერაცია

Once the drivers are correctly installed and the Raspberry Pi is powered on, the display should automatically initialize and show the graphical interface of your operating system. The FBCP (Framebuffer Copy) software driver allows for flexible display management, including setting custom resolutions and enabling dual-screen setups if you have another display connected.
