ZTE projector with a 5-inch display and autofocus function. Although there is some screen burn, projection itself is possible without any problems. As a mobile projector, the projection size is from a minimum of 5 inches to a maximum of about 120 inches, and the maximum brightness is 200 lumens, with keystone correction available. Equipped with an autofocus correction function, the display angle and focus will be automatically adjusted within a few seconds on a flat surface. For external input, it supports HDMI connection and wireless connection via Miracast, allowing projection from various devices compatible with the standards, such as smartphones, PCs, and game consoles. The video from external input is displayed not only by the projector but also on the built-in display. In addition to the built-in speaker, it has an earphone jack and Bluetooth 4.0 connection function, allowing you to project videos while playing audio on external speakers. Please check for yourself before purchasing, as some apps may not be usable depending on the Android version. The outer box is also available, but I don't intend to send it due to shipping costs. If you absolutely need the box, please let me know before purchasing. In that case, it will be an additional 500 yen. - Brand: ZTE - Connectivity: Wi-Fi - Display Size: 5 inches - Features: Autofocus - Apps: YouTube, Google Play, WPS Office Thank you for viewing.
