High-Visibility Images in Artificial Light

Dynamic Picture Quality with 20,000:1 Contrast

The PT-LB426 Series has high 20,000:1 contrast, a 25 % increase over the Panasonic PT-LB425 Series LCD projectors. The extra contrast adds high-impact dynamism to picture quality, reducing color washout under lights, sharpening details and outlines, and improving text legibility.

High Brightness Images in Natural or Artificial Light

Despite weighing just a little more than an average laptop PC, the PT-LB426 Series outputs between 3,100–4,100 lumens* for an impressively bright and vibrant picture. Strong luminance, contrast, and color means there’s no need to dim the lights during presentations, helping your viewers to concentrate.

* PT-LB426 (4,100 lm), PT-LB386 (3,800 lm), PT-LW376 (3,600 lm), PT-LB356 (3,300 lm), PT-LW336/LB306 (3,100 lm). Measurement, measuring conditions, and method of notation all comply with ISO/IEC 21118: 2020 international standards. Value is average of all products when shipped.

Daylight View Lite

Daylight View Lite optimizes color and brightness according to ambient lighting levels. This function is easily accessed using the supplied remote control.

Low Maintenance and Long Life

Long-life Lamp Lasts 20,000 Hours*

A breakthrough in materials design has paved the way for a new 20,000-hour* low-degradation lamp. Unlike conventional UHM lamps, it is intended to perform right through to the next projector refresh cycle without needing replacement, and therefore exhibits extended brightness retention.

* Lamp life is approximately 20,000 hours in Eco Mode and approximately 10,000 hours in Normal/Quiet Mode. Replacement timing varies depending on operating environment and usage conditions.

Long-life Filter is Easy to Access

Accessed via a convenient side-panel door, the long-life air-filter effectively limits dust intrusion for between 5,000 hours at full brightness (Normal Mode), 6,000 hours in Eco Mode, or up to 10,000 hours in Quiet Mode*.

* Replacement timing varies depending on operating environment and usage conditions.

Multi Monitoring & Control Software

Manage up to 2,048 devices via network with system map visualization and auto-search of unregistered devices. The free software is available with Early Warning functions* (free 90-day trial). These enable real-time monitoring, abnormality detection, and much more.

Multi Monitoring & Control Software and Early Warning Software (Product Information)

Note: Excluding the PT-LB306.

* Early Warning Functions (ET-SWA100 Series) are included free with Multi Monitoring & Control Software Ver. 2.0 and later, but require a paid license key and activation to continue usage after a 90-day trial period. Click here for more information.

Flexible Installation, Easy Operation

Seamless Transitions with Dual HDMI®

Switch content, not cables with HDMI inputs* connecting two laptops (or other HDMI-ready players) at once. Instead of passing a cable around and waiting until a new device is connected, one presenter can display content from their PC as another readies their media for seamless transition to the big screen using the remote controller, preserving the flow of the presentation. Naturally, the extra HDMI input is also useful in permanent installations for receiving high-resolution signals via existing interface switchers and media servers.

* PT-LB306 has one HDMI input only. High-definition content is converted to the projector’s native resolution upon projection.

USB DC Outlet*1 Supports Optional Wireless Casting*2

USB terminal is ready to accept the optional ET-WML100/AJ-WM50 series wireless module*3, which encourages group collaboration by allowing anyone with a free Panasonic app*4 or PC software*5 installed on their device to mirror their screen to the projector, displaying everything from work documents to video to websites. Further, the 5 V / 2 A DC terminal can power third-party media streaming modules*6, so there are fewer cables and less clutter.

Note: Wireless network function not supported on the PT-LB306.

*1 PT-LB306 has a USB terminal for service only.

*2 Optional ET-WML100/AJ-WM50 series wireless module is subject to regional availability and requires Wireless Projector app for iOS or Android™ or Presenter Light (for Windows® PC) to enable wireless projection.

*3 ET-WML100 Series and AJ-WM50 Series devices are both compatible with supported projectors in this series, and either can be used to enable the wireless network function.

*4 When using the Wireless Projector app, display resolution differs depending on your iOS/Android device and the display device. The maximum supported display resolution is WXGA (1280 x 800).

*5 When using Presenter Light Software, images are projected with 1280 x 800 dots or 1024 x 768 dots onto the screen. Also, your PC display resolution may be forcibly changed, and audio playback disrupted or become noisy, while images and sound are being transmitted.

*6 Panasonic cannot guarantee compatibility with third-party media streaming devices.

Image Adjustment for Distortion-free Projection

Manual 1.2x zoom lens control composes a large-format image from your desktop setup position and gives leeway for ceiling installations, ensuring sharp focus even if the mount position is not at precisely the right throw distance. V/H Keystone Correction (H: ±35 °, V: ±35 °) aligns image geometry when projecting off-axis to the screen center, while Curved Screen Correction tames distortion when shooting onto a convex or concave surface.

Note: PT-LB306 has vertical keystone correction of ±30 ° only and does not support Curved Screen Correction. Above throw-distance is for PT-LW376/LW336 in 16:10 aspect ratio producing a 100-inch image. PT-LB426/LB386/LB356/LB306 requires 3.0 m–3.6 m throw-distance and 4:3 aspect ratio for a 100-inch image.

Light and Compact for Easy Portability

Intended for effortless room-to-room portability or as a permanent on-ceiling solution supporting Panasonic software or third-party control protocols over LAN*, the PT-LB426’s light 2.9 kg (6.4 lbs)* weight makes handling a breeze. Manual controls let presenters set up quickly and easily on-site and commence their workshop almost immediately with less wasted time.

* PT-LB306 weighs approximately 2.8 kg (6.2 lbs). Weights are estimated based on average of all shipped products. PT-LB306 does not feature a LAN terminal or network control capability.

Selectable Modes Suit Your Projection Priorities

Choose your preferred mix of high brightness, extended maintenance, or quiet operation. Normal Mode prioritizes picture quality in bright environments, while Quiet Mode projects at a virtually inaudible 30 dB*1 with an extended filter replacement cycle. Eco Mode strikes a useful balance between the two with 20,000-hour*2 lamp-life and 35 dB*1 operation.

*1 38 dB in NORMAL Mode.

*2 Lamp life is approximately 20,000 hours in Eco Mode and approximately 10,000 hours in Normal/Quiet Mode. Replacement timing varies depending on operating environment and usage conditions.

Other Features

Memory Viewer Light

Insert a USB memory device into the USB port and start projecting stored content straight away without need of a connected PC. The USB media player supports a variety of image files, such as JPEG and PNG. Start your presentation right away without having to connect to a computer.

Note: Excluding the PT-LB306. Still images only. Video reproduction is not supported.

Direct Power Off

Projectors with Direct Power Off function allow you to switch off the projector and unplug the power cord right after use. You can safely turn off the room’s breaker switch without waiting for the projector to cool down. This is useful in applications where the projector is mounted on the ceiling, or in time-critical situations.
