Epson Pro L1755UNL Laser Projector Review- Special Features 3

Posted on March 26, 2019 by Phil Jones

Epson ProL1755UNL Laser Projector Review – Special Features: Content Over IP, HDBaseT & 3G-SDI Support, Split Screen, Multi-PC W/Moderator & Easy-MP, DMX Art-Net, DICOM Simulation


Content over IP is hardly a unique feature but a very useful one for any application were computers and projectors are being networked, for example in business settings or schools. In the past, the only way to show content on a projector from a computer or video source was to physically connect them. With many networkable projectors, it is now far easier to display content using a laptop located on the other side of the room. The ProL1755 can access and present content directly over the network. While it works well with computers and various video sources, it also plays the BYOD (bring your own device) game well, working with tablets, smart phones, etc. via an optional wireless module.


If you need to run a video signal hundreds of feet, the Pro L1755UNL offers two solution:

  1. HDBaseT lets you run HDMI distances of up to 100 meters (about 328 feet) over a low cost CAT5e/CAT6 wire. While the support is built into the projectors, you will need the optional transmitter to implement it. Epson sells an optional HDbaseT transmitter, the ELPHD01 which retails at $499 and supports resolutions up to 1080P/WUXGA. The cost savings of using HDBaseT can be significant which make it a very compelling feature for many installations. 
  2. 3G-SDI is another great long-distance solution especially for live video.  This feature allows the projector to interface directly with a video camera (up to 1080p / WUXGA) located 100 meters away via coax. This is a big feature with big benefits for rental and staging customers, such as Houses of Worship (which are major users of live video and projectors), convention centers, university classrooms, corporate auditoriums and training rooms.

FYI, there are several additional SDI standards including HD-SDI which supports 720p/WXGA content and 6G-SDI which can support up to 4K resolution. Many users of large venue projectors are just fine with HD-SDI support.  


While split screen capability is fairly basic compared to some of the other features, it is still worth discussing.  These Epson laser projectors can project two sources at once, not only can you show content in two similar-sized windows, you can also make one window larger than the other. Unlike many projectors claiming split screen, both sources can be live content (i.e. video). Once you have selected the two desired video inputs, you can quickly switch the images from left to right, change the sizes, and switch which sound source to output.


These are two of Epson’s software solutions that are compatible with all Epson’s networking projectors. 

First, the Multi-PC Moderator lets you use the L1755UNL to project up to four different sources (computer, tablets or phone) simultaneously onto four quadrants. That could be two PC’s an iPhone and a tablet, or some other combinations. The four sources can be chosen from up to 64 separate sources selected in Moderator. This application could be perfect for classroom type trainings, as well as for showing content simultaneously from different types of sources.

If you would like to learn more about Moderator, we did a full length video featuring the Multi-PC Moderator capability with one of Epson’s low cost installation projectors. To check it out click Epson PowerLite 97H (Summary) in the link below:


The demonstration starts 5 minutes and 2 seconds into the video. This is another great feature for classrooms, video conferencing environments, houses of worship, training rooms, etc.

Easy-MP is Epson’s simple command and control program that lets you control projector from computers over a network. Consider it a simpler alternative to major protocols such as Crestron RoomView. 

Easy-MP is free, it can be downloaded from Epson’s support site. Previous testing has proven that Easy-MP works well and provides lots of advanced control, including the list below which was also included in the networking section earlier in this article:

  • Remote access and control through a network
  • Remote monitoring of up to 1,024 Epson networked projectors
  • View status – including input sources, power on/off, lamp life hours and more
  • Email notification (SMTP) to send alerts to your handheld device or computer
  • Preventative maintenance features including temperature levels and error alerts
  • Pre-schedule timers to alert filter and lamp replacement needs
  • Enterprise SNMP plug-in available


DMX is an older command and control system that is best known for controlling lighting. DMX is still used heavily today for stage work and in classrooms. It is still a viable solution for theaters putting on live shows and concerts.

With DMX Art-Net, this projector can be controlled/automated along with the rest of the lighting. I can see where it would be a powerful way to tackle things like projection mapping (which is utilized in many concerts these days.)


The Pro L1755UHL has a DICOM simulation color mode which is designed to present medical images – such as X-rays, CAT-scans, MRI’s PETs etc., with enough contrast, detail and quality along with minimal noise for use in medical schools, at medical conferences and for education purposes, etc.

DICOM Simulation is not high enough quality nor intended to be used as a substitute for doctors reading original medical films. However, it is ideal to be used in a classrooms or teaching settings for training doctors, nurses and technicians.
