LG AU810PB 4K UST Business Projector Review – Hardware: Inputs and Connectors, Lens, Control Panel, Remote Control, Menus
The M2 is designed to be compact, and easily portable. Dimensions are: 8.8”x 2” x 8.8” and It weighs just under 3 lbs. When facing the unit, the projector’s lens is located on the left side of the front panel. There are sensors on both sides of the lens, and an air vent on the right half of the panel. There is no manual Focus and Zoom. The right and left panels of the projector (when facing the lens) are solid with no inputs or vents. The rear panel contains all of the connection inputs and a power button. On the bottom, there is a USB connection intended for a Wi-Fi dongle that is accessed through a plastic cover to a small compartment.
The M2’s control panel is located on the back of the projector, on the right side. Whether the projector is placed on a table or ceiling mounted, the control panel will be easily accessible. There is only a power button on the control panel, so it is important to keep track of the remote.
All of the connectors for the M2 are located on the rear panel of the unit. There is a 3.5mm audio out jack, 1 HDMI input, 1 USB 3.0 type-A, and 1 USB 3.1 type-C. The power adapter also plugs in to the rear panel.
The M2 has a fixed lens with no optical zoom, and a throw ratio of 1.23. Image size is adjusted by moving the unit either closer to or farther from the projection surface. A 100 inch image is attainable at just under 9 feet.
Throw Distance for a 16:9 Screen
The remote control for the ViewSonic M2 is about 6-9 inches long (depending who you ask), and black in color. It has a directional navigation pad, volume control, and several options for accessing various settings and apps. The buttons are laid out in an easy to learn configuration, have a positive “click” when pressed, and the overall construction feels solid, but it does make some creaking noises if gently squeezed while pressing the buttons. The battery compartment is on the bottom, it is unmarked and can be difficult to open. Because of this, I was worried I might damage the remote trying to open the battery cover, but it wasn’t an issue. The M2 has IR sensors on the front and rear of the projector, so the remote works from a variety of angles, and I wasn’t able to find one where it didn’t work. There is no backlight on the remote, which is standard for projectors of this class, but mildly frustrating when operating the projector in the dark.
When powered on, M2 home screen allows the user to access their favorite apps (customizable), the Aptoide store, Apps Center, Settings, Inputs, File management, and Screen mirroring. Users can add up to 4 apps to be easily accessed from the home screen.
The inputs menu gives the option of selecting between either HDMI, USB-C, USB, MicroSD, and Local Storage.
The screen mirroring menu initially opens instructions and a QR code to download Google Home. A Google account is required to utilize the Screen mirroring feature.
Under “Settings”, the user can access: Network Settings, Basic Settings (language, projector orientation, keystone, focus, Bluetooth, eye protection, voice control), Date and Time, Firmware Upgrade, Advanced Settings (default source, tones, multiple power options, light source level, high altitude mode, factory reset), and Information.
Conveniently, picture settings can be adjusted without exiting the current app being used.
