4. Lift the assembled monitor upright, position it on your floor or wall, and guide your HDMI and power cords neatly through the setup’s internal cable management pathways. 

1. Tap the physical power button located on the bottom frame or right edge of the panel frame.
2. Use the physical menu navigation or touch layout to open the on-screen display console.

• Does this monitor include built-in stereo speakers?
  Yes, the Dahua LCH75-MC410-B features a high-performance,embedded directly into the chassis frame. To play audio from your connected computer, you do not need external desktop speakers, though a 3.5mm line out is available if you prefer high-fidelity surround sound.
• Can I mount the Dahua LCH75-MC410-B onto a third-party desk arm or wall mount?
  The massive 75-inch commercial chassis is built for heavy structural placement. It natively supports standardized heavy-duty wall mount frameworks and professional industrial mobile rolling stands instead of basic desktop monitor arms.
• Is this display panel glossy or matte?
  The monitor features an advanced, pro-grade anti-dazzle tempered glass finish. This matte treatment diffuses incoming room light and harsh window reflections effectively, allowing you to work comfortably in brightly lit spaces or corporate boardrooms without experiencing blinding glares.
• How does the interactive touch engine affect my office work compared to a 60Hz screen?
  While high-speed touch responsiveness is great for quick whiteboarding, its primary benefit in an office setting is reduced visual fatigue. Sweeping your stylus cursor across the screen, moving windows, and scrolling through dense web articles or long data documents feels noticeably smoother and more natural, which significantly lessens eye strain over long working hours.
