4K I am offering a projector with many features. It has high brightness and an auto-focus feature that works on the wall or the screen. It operates on the Android system and includes screen mirroring for mobile devices. The speakers are powerful, so you don't need to buy separate speakers for it. It supports all applications and more. The price is 600 and not negotiable. WhatsApp number: (( Phone number appears when clicking the contact button ) ) Resolution: 4K
