15.6" Touchable Portable Monitor, External Screen, Portable Display

Welcome to ask questions. 15.6 inch FHD sRBG100% (see color in image). The menu button allows adjustment of various functions (display, color, language, etc.). Can connect to Android phones and laptops. Using Type-C connection enables touch control; Mini HDMI connection also supported (but without touch function). **Have not tested with MacBook, iPad, or iPhone due to lack of devices on hand 🤣** Built-in battery, but it's better to use while plugged in. A faint vertical line suddenly appears on the left side of the screen, especially noticeable on blue backgrounds—please do not bid if this bothers you (refer to image; this was not present before 🫠), but it does not affect touch functionality. The device has built-in speakers, a power button, and a menu button. Comes with a protective case and pre-applied screen protector. (The screen protector has marks from the case's clip—please check the last image.)
