LG PROBEAM BU60PST LASER BUSINESS PROJECTOR REVIEW – HARDWARE

LG ProBeam BU60PST Laser Business Projector Review – Hardware: Control Panel, Remote Control, Inputs and Connectors, Lens, Menus

The LG ProBeam BU60PST is dense and compact so it will fit in spaces where many 6000-lumen laser projectors would not. Dimensions are about: 14.6 "wide x 6.1" high x 11.4" deep (cabinet only), with the lens protruding an extra 1.4" (12.8" total depth plus connectors). The projector weighs about 21.4 pounds.

When facing the unit on a tabletop, the projector's lens is located on the right side of the front panel. Adjacent to the lens on the right side of the cabinet is the power cord connection and lens shift adjustments. Cooling air intakes are also located on the right side and also on the front of the unit.

On the back panel is the cooling exhaust as well as the combined power button/joystick for the operation of all functions. All the connections are also located on the rear and include two HDMI inputs, a couple of USB ports, and an HDBaseT connection

LENS

The ProBeam BU60PST has a manual lens with focus and zoom on the outer rings. With a zoom range of 1.6x it allows for placement at throw ratios of between ~ 1.3 -2.1:1. This can quickly be calculated using the width of the screen as follows:

Throw Ratio = Throw Distance /Image Width

For example, on a 100" wide image, the throw distance would be between 130" and 210".

Since screen sizes are often listed as diagonal and algebra is not most folk's favorite thing, we have provided this chart for your reference.

Throw Distance for a 16:9 Screen

Screen Size (Diagonal)Min Screen Distance (in)Max Screen Distance (in)  
80"                            90.1  (2290mm)145.6 (3700 mm)
100”113.3 (2880 mm)182.2 (4630 mm)
120”136.2 (3460 mm)218.5 (5550 mm)
140”159  (4040 mm)255.5 (6490 mm)
160”181.8 (4620 mm)292.1 (7490 mm)

As we mentioned earlier, the ProBeam BU60PST has both horizontal and vertical lens shift. Like all projectors with H/V shift, moving the image in one direction will limit the amount of shift available in the opposite direction

Lens Shift (Hortizontal +/- 20%, Vertical +/- 50%)

The horizontal and vertical lens position adjustments are made using two concentric dials on the right side of the cabinet. As you turn the wheel, the image accordingly until you reach the limits of adjustment. Turning the dial further will result in a noise that indicates the dial is slipping, which helps avoid the damage from turning a lens adjustment too far.

While aligning the image to the screen via optical lens shift provides the best image quality, the ProBeam BU60PST also includes a 12-point warping feature which is more precise than traditional digital horizontal/vertical keystone correction.

The remote control for the ProBeam BU60PST is white with all rectangular-shaped buttons. The design has a generic button layout with a few notable inclusions, particularly the direct access to picture modes and energy saving (laser power) settings. These buttons make quick adjustments for source material and lighting conditions a snap for end users. With the press of a single button, a user can go from making a presentation in a fully bright room to watching sports or TV after dark.

You can also control the ProBeam BU60PST via a wireless keyboard and mouse. All functions can be accessed using a mouse cursor. Navigating websites or media playback is also more convenient, particularly when entering required text for account information or typing URLs.

MENUS

The LG ProBeam BU60PST has two different onscreen GUIs. One screen allows for setup and adjustments, and the other screen manages the content and online access via WebOS. The photo below shows the icons for the Settings menu on the left as well as some of the available options.

Operation of the WebOS features are simple and straight forward without all of the apps available on a typical LG TV.
