Review on ELECROW 8" Portable Touchscreen for Raspberry Pi, 1280X800P Display, Integrated Speakers & HDMI Support by Daniel Fadaifar

This screen is not what it advertises. There are only two aspect ratio options in the OSD menu. 16:9 and 4:3. Declared resolution (1280x800) - 16:10. Choosing 1920 x 1080 will give you black borders on both sides and will shrink the image. In addition, the refresh rate of the device is just under 60 Hz (59.94). This causes flickering on any device that can't output a certain refresh rate or when you try to mirror the screen. It may have bad firmware but I can't fix it. Send back.
