Review on 📷 BOYO VTM4000 - 4-Inch TFT-LCD Rear View Camera Display by Kev Mills

I used a VTM4000 display with a Boyo VTL375HD rear camera. Together they create an outstanding picture. The monitor has an excellent suction cup mount. It sticks well to the window and I doubt it will fall off on its own. There is an optional disc that can be attached to the dash using the self-adhesive foam tape provided. The suction cup is then attached to this smooth plastic disk. The monitor has brightness and contrast settings that can be accessed via 3 small buttons on the back. There is also a small removable sun visor. I set the brightness to 70, which helps when wearing sunglasses, and had no trouble seeing the display in bright sunlight. The monitor has two separate input sockets. I hooked up a camera to each of them and they work the same way. I don't know what happens when you connect two active cameras to two ports. I can recommend this monitor without hesitation.
