== Notes and version constraints ==
* The exact power consumption (approx. 12V 340–500 mA) and the precise power supply specification (outer Ø 3.5 mm / inner Ø 1.35 mm) should be verified before purchase or operation with a suitable power adapter.
* Installing the screen requires support elements; the mounting accessories mentioned in the wiki are not included in the kit.
* When mounting at an angle, the angle between the back of the LCD and the horizontal must be at least 75°, otherwise the panel may fall off.
* Some PCs do not support plug-and-play with HDMI devices; a system restart may be required.
* The PWM backlight control procedure requires soldering work on the board (removing a transistor and soldering at the pad location). This should only be performed by experienced individuals.
* According to the source, the long-press (right-click) function is supported only on 32-bit systems and is not supported by default on 64-bit systems.
