Review on Elecrow Raspberry Pi 5 Capacitive Touchscreen Interface - Portable HD Monitor, 8595698868 by Adam Trundle

You need another monitor to view the stats on the monitor. The quality is a bit grainy, but that's okay, just like an old smartphone. In fact, you can even use your phone to monitor. But either way, the resolution might be better than advertised, but the words get really small. Colors are a bit washed out, but that's the way it is on a small screen anyway.
