How to Install ViewSonic PX748-4K

• Choose the right placement: Position the projector at an appropriate distance from the screen or wall to achieve the desired image size and a clean throw alignment. Consider a flat, stable surface or a ceiling mount for a clutter-free setup.
• Connect your devices: Use the Dual HDMI ports to attach a Blu-ray player, game console, or streaming dongle. If you prefer a single-cable setup, connect a laptop or streaming device via USB-C and power both the source and projector as needed.
• Power up and align the image: Plug the projector into a power source, turn it on, and use Auto Keystone to automatically correct trapezoidal distortion. If necessary, make manual adjustments to focus and lens shift (if available) to center the image precisely on your screen or wall.
• Configure picture settings: Access the projector’s image menu to select 4K UHD input, enable HDR, and pick the appropriate aspect ratio for your content. Tweak brightness, contrast, color temperature, and sharpness to suit your room’s lighting and your personal preferences.
• Set up Netflix and streaming: If you’re streaming Netflix via dongle, attach a compatible streaming device (like a streaming stick or mini PC) to one of the HDMI ports or USB-C, and switch to that input. Ensure your dongle has network access and the latest firmware for smooth streaming.
• Sound and seating considerations: If you’re using external speakers or a soundbar, connect them to the projector’s audio output or route through your media receiver. Position seating for optimal viewing distance and to maximize perceived depth and color richness.
• Test and save presets: Run a short video or game to verify color fidelity and motion clarity. Save your preferred picture mode as a quick-access preset for easy recall during movie nights or gaming sessions.
