Review on ZSCMALLS Portable Lightweight Cellphone Raspberry 15" Monitor with Built-In Speakers, Ultrathin Design, Plug and Play, HDMI Connectivity, Ultralight, and Full HD Resolution (1920x1080 @60Hz) - ZSC-T15A2 by Roger Galloway

So the display is definitely not very bright (no matter how you turn it on), but that CAN be normal with displays like this. If a dark screen doesn't bother you, don't let it bother you. But it's noticeably dark. With this in mind, I am concerned that the item I received was defective and a piece of the image at the top of the screen was cropped off instead of showing at the bottom of the screen (above the bottom of the screen). Windows taskbar). No screen center settings, and it didn't matter what connections I used. Strange. Also, the screen could be sharper (in practical terms) since it has very thin "scan lines" like older monitors. But that wouldn't be a deal breaker for me. The usage is office work and I could read it well (if only it was brighter). Returned.
