Let's run through all the button and their purposes on the BenQ remote control. First though, I consider this one of the best remotes out there. It's light, fits well in the hand, has a nicely, but not too bright orange backlight. Well spaced, and very good range exceeding 25 feet. Very similar to many remotes going back about a decade. I guess if you get it right, you don't have to mess with it much.
From the top:
On the left top, power on, top right, off. The next two rows of three have your individual source buttons
The two rows below have a total of five buttons. There's one for each of the five aspect ratios.
All of those have text on them identifying them. The next five buttons are the only ones where you need lights to read what they do. The first one, in the center lets you toggle though all the preset and user modes. The four below it give you direct access to User 1, 2, and 3, plus there's a default button.
In the center is the navigation area, with the four arrow keys in round formation, and a center Enter button. The Menu button is just below to the left, and the Exit button (oft called escape) is opposite it, on the right. Exit moves you back up a level in the menus.
That brings us to the bottom third, where the first four (round buttons) provide direct access to Brightness, Contrast, Color Saturation, and Tint. The next three buttons are PIP - main PIP menu, PIP window size, and PIP window position (which corner) Right below PIP is the Active control which lets you set whether the main or PIP window is active. In the middle of the last row is 3D, and to the right of it the Invert button for the 3D glasses.
Wait, one more button, larger, further down, that's the backlight button.
