Epson ProL1755UNL Laser Projector Review – Special Features: Network Management Tools, Auto Color Correction (Image Correction Camera), Array of Interchangeable Lenses, CFI- Creative Frame Interpolation

NETWORK MANAGEMENT TOOLS

Once you have connected your projector to your network, you can control the Pro L1755 using a compatible web browser. This allows you to access the projector remotely and control things like focus, zoom, shift and test patterns. You even set up a networked projector to send you an e-mail alert if there is a problem. The email will list the name of the projector experiencing a problem and detailed information about the issue. In addition to being able to control an Epson business projector via a web browser, Epson offers two software program options which can be used to monitor and control a business projector.

Epson Projector Management software allows you to check the status of multiple networked projectors and perform various projector operations from your computer. You can monitor the status of multiple projectors and get information such as such as power status, errors, and warnings so you are alerted to projector abnormalities immediately. You can also select individual projectors or projector groups to check detailed information such as the usage hours of the projector light source, the current input source and any current errors or warnings. This software is more focused on monitoring.

The Epson Projector Professional Tool offers further flexibility by allowing you to adjust and control images projected from networked projectors using a computer. You can focus, shift, zoom, apply Geometric Correction, fine tune Edge Blending and much more on multiple projectors without having to reach for a remote control. This software option is more focused on control. 

Of course, the Pro L1755UHL is also compatible with 3rd party control systems such as the Crestron RoomView network monitoring and control system, which also allows you to setup and adjust a networked Epson projector.

AUTO COLOR CORRECTION (IMAGE CORRECTION CAMERA)

Image Correction Camera

As discussed earlier, after several thousand hours the color of a projector, even one with a laser light engine, can shift. To ensure long-term picture quality, the L1755UNL also includes an Auto Color Adjustment feature which uses a built-in camera and the laser light engine to adjust for color uniformity. 

This feature can also be utilized for multiple projectors because according to Epson, it can “detect subtle color inconsistencies between multiple projectors and screens that have become unevenly colored over time”. 

Since I only had one projector at my disposal, I didn’t have the opportunity to test this feature, but I am confident that it would simplify color matching multiple blended projectors. You can automatically correct the brightness and tint for multiple networked projectors based on the settings you selected for the master projector. Select Multi-Projection for the Color Mode setting then adjust the Brightness, Contrast, Color Saturation, Tint, White Balance and Advanced settings in the Image menu on the master projector. When the screen matching feature is selected, the projectors will use built-in cameras on the front to the right of the lens to match the projectors color, white balance and brightness.

ARRAY OF INTERCHANGEABLE LENSES

Several models in the Pro L series lineup are available both with or without a lens. The “NL” at the end of the model number indicates that no lens is packaged with that specific model. While the Pro L1755UNL does not have a lens in the box, it is compatible with nine powered Epson lenses. Upon detecting certain installed lenses, the projector will adjust its maximum brightness level as outlined in the chart below. Also included on the chart is the throw range for each lens.

Lenses compatible with Epson Pro L1755UNL

For this review, Epson provided two lenses and both lenses provided allow the projector to deliver its maximum brightness level. The ELPLM15 lens which is a middle-throw zoom lens with a range of 1.57 to 2.56. They also provided their ultra-short throw lens ELPLX02 which has a fixed throw ratio of 0.35. 

While the ELPLX02 lens has a very short throw distance, its throw is not as short as a UST projector with an integrated lens. To project a 120 inch image, the Epson Pro L1755 projector must be approximately 28 inches from the screen while a dedicate UST projector, like the Sony VZ1000ES, can be as close as 10 inches.

You may be prompted to calibrate the lens when it’s swapped. Lens calibration helps the projector to correctly acquire the lens position and adjustment range and can take up to 100 seconds to complete. When calibration is finished, the lens returns to the same position it was in before calibration.

CFI- CREATIVE FRAME INTERPOLATION

All of Epson’s L series laser projectors offer CFI, not just the L1755UNL. With CFI (creative frame interpolation or sometimes called “smooth motion”) in low frame rate content additional frames of information are generated in between the original frames, reducing judder resulting in smoother motion. 

This is a common feature on home theater projectors over $2,000 and is also available on several commercial projectors. Epson has a lot of experience implementing CFI on their home theater models, so no surprise that it works very well on the Pro L1755. Smoothing is effective, reducing the judder on 24fps content and it also works well with faster frame rate material. Note, like several other features, CFI is disabled when pixel shifting is engaged.
