Your MacBook or Surface is all USB-C. The projector in the staff room still has a VGA port. You don't need a new projector; you need this adapter. Plug it into your laptop, connect your VGA cable, and you've got Full HD 1080p at 60Hz on that legacy display. Handles QXGA, QWXGA, WUXGA, and UXGA resolutions. Aluminium shell, gold-plated contacts. One honest caveat: no audio signal passes through it, so pair a separate speaker or use your laptop's built-in audio. Works with Windows, macOS, and Android. One-year warranty
