Split Screen Capabilities
This Epson not only can use Epson's Moderator software to put up to four sources on the screen at once (a local network needed) in different windows, it can also do Split Screen.
Although this image is not from the PC1985, most other Epson bright room projectors have the same split screen functionality. Shown here with one of the split-screen menus up, is a computer source on the left, HDTV on the right.
With Split screen you can display two sources at the same time. The only real downside, one that seems to be standard with split screen supporting projectors, is that you can't use HDMI 1 and HDMI2 as the sources. Only one HDMI can be used, the other source can be just about anything else, from component video, to a PC (analog computer input), to Display USB, to streaming with Miracast.
When you are split screening, you have a choice of image sizes. Both images can be the same size, or one can be about twice the size of the other. The larger one can be on the left or right, and you can switch sources from one side to the other. Overall, other than that one limitation of not using two HDMI inputs, it's very capable and flexible. I've put up my MacBook Pro signal (by outputting an analog computer, using adapter from the HDMI port), next to the HDMI source from my cable box, in order to view my fantasy football tracking on my Mac, in the smaller window while having a game playing in the larger one. Bottom line: Epson's split screen is a fun extra feature, just be sure to figure out your wiring so you can get two up there without them both being HDMI.
PC Free Presenting
The Pro Cinema 1985W offers basic PC Free presenting by way of an onboard media player. The 1985W supports image files and PDF, but is not as extensive as some, as it does not support Microsoft Office formats. This feature can be used to display those images wirelessly, or you could plug in a USB thumb drive with the images on it.
It's actually a very simple way to quickly view photos from your digital camera if they are in a standard format such as JPG. Now I mostly use for photography, either an iPhone, or my dSLR. For work purposes when using the dSLR, I shoot in Canon's raw file format (.CR2), but I usually have my camera set to also store them in a medium JPG format, so I can view the images on an Epson projector. (My G series Epson has the same feature.) I can copy my photo images from my SD card to a USB drive, OR, transmit them wirelessly from the SD card once plugged into my laptop, OR, I can plug in a basic media card device (that you can plug in SD, XD CompactFlash, micro-SD, and other cards, with a USB connector on the other end) into the 1985's USB input.
Bottom line: The PC presenting can be used for serious things, such as displaying a Powerpoint presentation as a series of JPGs, but it also works great to view your photos wirelessly from a computer, or using USB or media cards via USB input. There are auto features to run the slide show, timing and basic effects.
