If Optoma’s goal was to make the control panel nearly invisible. I’d say they were successful. They kept the number of buttons to a minimum. Some companies will add a number of extra buttons for quick access to more features, but, from a practical standpoint, other than installers, we live and die by the remote control.
The power and input source buttons are located along the rear edge of the right side of the projector, as shown in the upper photo above.
The remaining controls, for navigating the projector's menus, are located behind the pop-open door on the top of the projector. These buttons are shown in the lower photo above.
Normally you would walk right by, not notice the controls, but for the power indicator light. That light will be red if the projector is off, or blue if on, and flashing while powering up or down.
The controls are straight forward, but have an odd arrangement by splitting them up in two locations.
Still, it’s perfectly functional. What it lacks are any “extras” which is not really a problem, as we all pretty much rely on the remote control.
