== Notes and version constraints ==
* Installing the screen without a case requires additional structural support; the components used in the reference example are not included in the package.
* The display must not be mounted parallel to the ground, otherwise it may fall off due to gravity.
* When mounting at an angle, the angle between the back of the display and the horizontal plane must be at least 75 degrees.
* Using the VGA input requires separately purchasing a mini-HDMI to VGA cable.
* Some PC systems do not support hot-plugging HDMI displays; in this case, restarting the PC resolves the issue.
* Headphone jack audio output functions exclusively during HDMI operation.
* When using other power supplies, ensure that the power supply ripple remains within ±5%.
