ViewSonic has long been a leader in the education projector market. One of its latest models, the LS625W, is both powerful and affordable. It shares some features with the LS620X (shown here) and the newer LS625X (the LS620X’s replacement), but in some ways, it even offers better specs.
Overview
The LS625W measures 15.1 x 5.8 x 11.5 inches (W x H x D) and weighs 13.7 pounds, making it compact and lightweight. Its recessed lens design helps protect it from accidental bumps.
Some controls are located on the top of the projector, which might be a bit hard to reach if it’s ceiling-mounted.
Like the LS620X and LS625X, the LS625W is a short-throw projector. This means it can be placed close to the screen—between 2.6 and 3.7 feet away—yet still project a large image. Thanks to its zoom lens, it can display screen sizes from 70 to 100 inches diagonally.
One big advantage of short-throw projectors is that they can be mounted right above the screen using a telescoping wall mount. This makes installation and cable management easier and more affordable.
The LS625W has a native WXGA resolution (1280×800), which is a step up from the XGA (1024×768) resolution of the LS620X and LS625X, so it looks sharper on bigger screens. It also has a built-in video scaler that supports resolutions from 640×480 up to 1920×1200 from both PC and Mac, offering flexibility for displaying different content.

Special Features
The LS625W, LS625X, and LS620X all use DLP (Digital Light Processing) imaging and a laser/phosphor light source. In this setup, part of the light from a blue laser hits a phosphor wheel, which produces yellow light. This yellow light combines with the remaining blue light to create white light.
That white light then passes through a color wheel made up of multiple colored segments. These colors are projected one after another onto a DLP chip, which creates the image for each color. The image is then reflected through the main lens onto the screen. The switching between colors happens so fast that our eyes blend them into a full-color image.
All three models use ViewSonic’s SuperColor technology. According to the company, this includes either a 5-, 6-, or 7-segment color wheel to enhance image quality. However, ViewSonic hasn’t confirmed exactly which type of color wheel is used in the LS625W. (Interestingly, the LS620X has been reported to use a 6-segment RYGCBW wheel, but when asked, ViewSonic still wouldn’t say what the LS625W uses.)
The LS625W is a compact projector with a well-designed, built-in lens.
Thanks to its laser/phosphor light engine, it can reach up to 3,200 ANSI lumens, making it bright enough for classrooms, even with the lights on. ViewSonic claims a dynamic contrast ratio of 3,000,000:1, achieved by adjusting the laser power in real-time. While the actual contrast might not hit that exact number, this dynamic control still helps deliver impressive image depth and contrast.
The sealed light engine protects against dust and moisture—great for classroom environments. Plus, the laser light source is rated to last 20,000 hours, meaning no more regular lamp replacements. In short, it’s low-maintenance and classroom-ready.
While the LS625W doesn’t have lens shift, it does include horizontal and vertical keystone correction to help square the image if the projector isn’t perfectly positioned. That said, keystone correction can slightly reduce image clarity, so it’s best used only if absolutely necessary.
The LS625W doesn’t have lens shift, but it does support both horizontal and vertical keystone correction to help straighten the image if the projector isn’t perfectly aligned.
For classrooms without a separate sound system, the LS625W comes with two built-in speakers, each powered by a 10-watt amplifier. That’s quite loud for built-in speakers—plenty for a standard K-12 classroom, and possibly even enough for a small college lecture hall.
Speaking of education, ViewSonic offers special programs for schools, including K-12, colleges, universities, and even museums.
One standout classroom feature is compatibility with ViewSonic’s PJ-VTOUCH-10S interactive whiteboard module. This module turns your projection surface into an interactive whiteboard using a camera and laser sensor to track finger or pen movement. Up to 10 users can draw or annotate directly on the projected content (like documents or web pages). Teachers can record and save annotations to share with students later.
If the projector is ceiling-mounted and hard to reach, no problem—the LS625W supports AMX and Crestron control systems, so it can be managed remotely over your school’s local network.
Hardware
The LS625W comes with a wide range of ports. For video, it includes two HDMI 1.4 inputs with HDCP 1.4, one S-Video, and one composite video input. It also has two VGA inputs, a VGA output, and a 3.5mm audio input.
A USB 2.0 Type-A port can power a streaming stick (5V/1.5A) connected to one of the HDMI ports. There’s also a Mini USB port for firmware updates and service.
A LAN port lets you connect the projector to your local network for control and content sharing. It also has an RS232 port for additional control options and a 3.5mm 12V trigger output, which can automate tasks like lowering a screen or closing curtains.
The rear panel offers a solid range of connections, including two HDMI inputs, S-Video, composite video, VGA input, a LAN port, and USB. The USB port can power a streaming stick plugged into one of the HDMI ports.
Despite its compact design, the projector offers plenty of control options. There are dedicated buttons for the HDMI and composite inputs, and the menu button can also be used for quick keystone correction. A numeric keypad allows easy control of functions like volume up/down/mute and zoom in/out.
Compact Design, Powerful Features
The LS625W has a compact build but packs a lot of features. You can adjust keystone correction directly using the on-body controls, and the number pad also provides quick access to key functions beyond just numbers.
Bottom Line
The LS625W uses a bright laser/phosphor light engine rated for up to 20,000 hours. Its short throw lens, network management support, and interactive whiteboard compatibility make it a great fit for education settings. With the optional ViewSonic digital whiteboard module, teachers and students can interact with projected images like a real whiteboard.
The projector’s WXGA resolution provides a 16:10 widescreen aspect ratio, making it ideal for new classroom installations. However, if a school is upgrading an older 4:3 aspect ratio projector, the LS620X or LS625X (also short throw, XGA resolution) may be a better fit. These models likely match existing screens and wall mounts, helping save on costs.
Replacing a 4:3 projector with the LS625W may require a new screen or mount, potentially increasing costs by up to 50% or more. For budget-conscious schools, this might mean upgrading fewer classrooms overall compared to sticking with 4:3 replacements.
The LS625W has a 16:10 widescreen aspect ratio, which is great for new installations. However, replacing older 4:3 projectors with it might be more expensive.
On the bright side, the widescreen format definitely benefits new setups—teachers often show movies, and this screen looks much better for that. Plus, the price is reasonable: around $1,300, compared to $1,200 for the LS625X.
If you’re buying a new projector for a classroom, the LS625W is definitely worth considering.
