This is no ordinary video adapter. Yes, it enables you to connect the USB-C™ port on your computer to an HDMI® display or projector, but it also features a unique Presentation Mode switch. When you turn on this switch, the adapter prevents your computer from launching its screen saver, going to sleep or entering power save mode. The adapter ensures that your screen will always stay on, making it the perfect USB-C video adapter for any presentation or meeting. Keep your audience engaged with your presentation When you deliver a presentation, your goal is to engage with your audience, not your computer. But, if you don't move your mouse soon enough, or change your power settings, your screen goes black due to inactivity while you're addressing the audience. This can be a major distraction when you're trying to focus on the message you're communicating. This adapter prevents screen disruptions with Presentation Mode, a unique feature that automatically initiates occasional cursor movement to prevent your computer’s power settings from interrupting your presentation. It’s perfect for sharing websites, drawings, spreadsheets, PDFs or slide shows during your meeting. Turn Presentation Mode on or off You can turn Presentation Mode on or off depending on your application. Turn it on when you're in the boardroom and want your screen to stay on, and turn it off when you’re using the adapter at your workspace or office hot desk, to enable your computer's original power settings to take effect. Using the toggle switch is easy, and saves you the hassle of constantly making adjustments in your operating system settings. Hassle-free setup and operation on Mac and PC To ensure easy operation and installation, this unique adapter is natively supported on Windows® and Mac computers. It’s easy to connect the adapter using the versatile USB Type-C™ port on your computer. The reversible USB-C connector means you will always plug it in correctly on your first try, which saves you the hassle and distraction of repeatedly attempting to connect your laptop to a display or projector. Supports 4K resolution at 60Hz This adapter lets you harness the video capabilities that are built into your computer's USB Type-C connection, to deliver astonishing UHD 4K 60Hz resolution to your HDMI 2.0 display. This makes it easier for you to multitask while you work on the most resource-demanding applications imaginable. With this adapter, you can achieve an output resolution of up to 3840 x 2160p at 60Hz, which is perfect for performing high-resolution tasks such as viewing 4K video.
