OBEST 4.3-inch Twin Monitor with 4 Video Inputs, Auto-Switching, Dual-Screen On-Dash Monitor, Sub-Monitor, and Backup Camera, Customizable, 12V/24V

[Simultaneous Display of Two Screens] Equipped with twin 4.3-inch monitors, you can check two screens at the same time. Each monitor has two video inputs, so for example, if you connect four cameras (front, side, and rear), you can check each screen from two cameras. [Automatic Video Switching] When using the two video inputs (V1/V2), the V2 video input takes priority. If you connect a backup camera that is linked to the reverse drive, the display will automatically switch to the backup camera image when reversing. [Angle Adjustment] A dashboard stand is included. It can be installed with double-sided tape. You can adjust the height and angle to your liking. [Power Saving Function] The monitor remembers the on/off status, so it will return to the previous power state when you start the engine. [After-Sales Service] The monitor's ultra-thin and lightweight design makes it compact, lightweight, and easy to install. If you have any problems, you can contact customer support by email at any time.
