This computer kit DOES NOT come with a Display/monitor/screen, offering freedom to use your existing TV (HDMI) or LCD monitor. Yet, we recommend the following display device:

• Acer 20-inch HDMI Monitor, without built-in Speaker
• BenQ 22-inch Full-HD Dual HDMI Monitor, with built-in Speaker
• 15.6-inch Capacitive Touch IPS 1920x1080 HDMI Display, with built-in Speaker
• 7 inch 1024x600 IPS HDMI Capacitive Touch Monitor, with built-in Speaker

So basically, it comes with all the necessary devices, yet allow you to choose the preferred HDMI display to kickstart your digital making. And I like the box, it is nicely designed with official Raspberry Pi color, red and white.

Features:

• Official Raspberry Pi 400 Computer kit from Raspberry Pi Foundation
• UK Layout, 79-key keyboard and UK Power Plug
• All parts can be reused for other purpose or projects
• Perfect for beginners
• Choose your preferred HDMI LCD monitor
• Comes with a 16GB microSD card with pre-loaded NOOBS, no extra work needed to boot up the Raspberry Pi 400
• Comes with a printed copy of the official beginner's guide, updated for Raspberry Pi 400
• Great family weekend digital making project
