Epson Powerlite Pro G7905 Large Venue Projector Review: Features 3

Posted on August 1, 2016 by Art Feierman

CFI - Creative Frame Interpolation

All of Epson's G series projectors offer CFI, not just the G7905U.  With CFI - creative frame interpolation - sometimes called "smooth motion" extra frames are inserted into the content, so that objects moving quickly across the images, from one frame to the next, can be smoothed by having those moving objects half way between frame 1 and frame two, by creating a frame 1a.

This is a common feature on home theater projectors over about $2000 and it's showing up on a number of commercial projectors as well.  Epson has a lot of experience with CFI, so no surprise that it works very well on the Powerlite Pro G7905 that I'm working with.  Smoothing is effective, especially on 24fps content, but also on faster frame rates.

Note, like a number of other features, CFI is disabled when pixel shifting is engaged.  That makes sense, since pixel shifting is already "firing" the panels twice, once, then shifting and firing again with slightly different processed data.

Epson G7905U - Advanced Networking and Emulation Mode

No surprises here, like all larger venue commercial projector manufacturers, Epson offers up some pretty advanced networking.  Much of that is accomplished by offering compatibility with Crestron RoomView, AMX, Extron XTP, and Control4 SDDP.

With all that support this Epson delivers remote monitoring, push notifications, messaging, scheduling, Content over IP, and a lot more.

We don't test networking, but these network control compatibilities in part, should assure you that the networking capabilities are there and work.

One very interesting new feature found on this G7905U projector is Epson's Emulation mode. Short version: It allows the new G series (and L series) projectors to emulate - and therefore accept Sony, Panasonic, Mitsubishi, and NEC command codes.

This is big, because it makes it much simpler to integrate one, or a number of these Epson laser projectors into existing networks of projectors that started out with projectors from those other brands.

It's only the past 4-5 years that Epson has been making a really significant push into larger venue projectors.  That's never been truer than this year with fifteen new large venue projectors - six G series, and nine new laser projectors, together spanning the range from 6000 to 25000 lumens.  By comparison, some of those other companies' have been building projectors have been going into large deployments for far longer.  If you are an IT/AV manager, should you have a lot of, for example) big Sony projectors, you can switch or add, going forward, Epson projectors without having to change all the protocols to Epson's standard ones.  (Good thinking, Epson!)

Content over IP

In the good old days, content came either from a computer, or a video source.  Many networkable projectors today, however have far more capabilities. The Pro G7905 can present content directly over the network, such as stored files and presentations.  Of course it can also work with computers, all kinds of video sources, and also plays the BYOD game well, working with tablets, smart phones etc. - there's an optional wireless module to help out with that. Epson uses the same $99 optional wireless module for almost all of their projectors.  (You might think Epson would throw it in on a $6499 G series - for free, or with a $12,499 laser projector, but they don't.)

Bottom line, Content over IP is hardly a unique feature but a very useful one for corporations, schools and school districts, etc. who are networking computers and projectors.

Epson G7905 Supports HDBaseT

HDBaseT lets you run HDMI distances of up to 100 meters (about 328 feet) over low cost CAT5e/CAT6 wire.  Support is built into these Epson projectors, but you will need the optional transmitter to implement.

The cost savings generate by using HDBaseT can be very significant.

One difference between this G7905 and the more expensive 7000 lumen Epson laser projector - the L1200 -  is that this one lacks HD-SDI or 3G-SDI.  (Those allow running hi-def live video long lengths over coax: HD-SDI at 720p, 3G-SDI at 1080p.)

Split Screen

This is pretty basic, compared to some of these features, but worth reporting.  These Epson G series projectors can project two sources at once, side by side, both with the same sized screen, or with the ability to have one be about twice the size of the other image.  Unlike many projectors claiming split screen, both sources can be live (i.e. videos).

One can quickly switch the images from left to right, change the sizes, and also quickly switch which source's sound will be output.

Multi-PC w/Moderator and Easy-MP

These are two of Epson's software based enhancements. Nothing new here, Epson's been offering Easy-MP for a really long time.  Moderator is newer, but also around for a few years.  You'll find compatibility with these capabilities on all Epson's networking projectors.

Here's what they are about.

Multi-PC Moderator loaded onto computers tablets or phones allows this Powerlite Pro G7905 projector (and other Epson's supporting Moderator, to project four sources simultaneously into 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.  Perfect for classroom type trainings, as well as for showing content simultaneously from different types of sources.

If you would like to see Moderator in action on another Epson projector we did a full feature on doing the Multi-PC Moderator capability on our video about one of Epson's low cost installation projectors.  To check it out click Epson PowerLite 97H (Summary)  The demonstration starts 5 minutes and 2 seconds into the video.  Pretty cool!  Great in classrooms, video conferencing environments, houses of worship, training rooms, etc.

Easy-MP is Epson's simple command and control that lets one control projector features from computers over a network.  Consider it a somewhat simpler alternative to major protocols such as Crestron RoomView.  I do believe it has been around for more than a decade.  It definitely works.  Easy-MP let's you do a whole lot of advanced control, including most of the things mentioned earlier in discussing networking:

  • Remote access, 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, computers...
  • Preventative maintenance features including temperature levels and error alerts
  • Schedule filter and lamp timer settings
  • Enterprise SNMP plug-in available

Easy-MP is free, it can be downloaded from Epson, but I believe it will also be on a disc in the projector box. (Our review unit was an engineering sample, so we didn't get software, manuals, etc.)

DICOM Simulation

DICOM Simulation means these projectors can present medical images - such as X-rays, CAT-scans, MRI's PETs etc., with enough contrast, detail, and quality, and minimal noise, so that these projectors can be used in medical schools, at medical conferences, etc., for education purposes.

DICOM Simulation is not intended, not high enough quality, to be used as a substitute for doctors such as radiologists, reading the original medical films (but these Epsons will get close).  But it is ideal for teaching doctors, nurses, and technicians.

DICOM Capable for Teaching / Displaying Medical imaging

I'm not sure if DICOM is used as a standard for other film reading purposes, such as X-rays of mechanical components, but projectors that are high enough quality for DICOM Simulation likely would be good at that, too.
