Epson Home Cinema 3100, 3700, 3900 Lens Shift Range
There's a good amount of lens shift range. If you are using a 100" 16:9 diagonal screen, the projector can be placed (measured from the center of the lens), anywhere from 5 inches above the top of the screen surface, to 5 inches below the bottom, including anywhere in between. That's based on 60% of 1 screen height, one screen height = approximately 50 inches, so roughly 30 inches above the center of the screen, equals 5 inches above the top.
Horizontal lens shift is more moderate at 24%, so up to about 21 inches to the left or right of center.
Remember, the more you use of vertical, the less horizontal available, and vice versa. If you use the maximum vertical (as an example) you would not have any horizontal shift available.
Epson Home Cinema 3700 Remote Control
Epson Home Cinema 3700 remote control
Epson uses the same basic remote control for many of their models, but labels some of the buttons differently to match up best with particular projectors.
The black Epson remote is about 10 inches long, feels solid and fits well into one's hand. From the top left:
There's a round power on button, and next to it, a smaller power off button. On the right is a slightly glow in the dark button for the remote's backlight.
Source inputs, including the two HDMIs (MHL support for streaming devices is on HDMI 2). One of them is for a LAN (in conjunction with the wireless module).
There's also a Home button (right side) to bring up the Home menu, and below that the P-in-P or Picture In Picture button. This Epson allows for a larger image and a smaller one.
The larger image fills the screen, the smaller one is inset, and can be in a small or larger thumbnail size.
To control P-I-P features, once you have hit the P-In-P button, then tap the menu button which will allow you to change the size of the smaller image, swap the larger image for the smaller one, and decide which corner you want the smaller image to appear. P-In-P works only with the HDMI inputs.
The next section consists of 9 buttons (three rows) for the HDMI link to control other HDMI-Link compatible devices such as properly equipped Blu-ray players. One of those buttons is an audio mute.
The next row left is the HDMI Link button which brings up a menu showing you which other HDMI link devices are hooked up, so you can select the one you want this menu to control.
This Picture In Picture image was shot with a different Epson - the 5040UB, but it works and looks the same on the Home Cinema 3700, 3100, and 3900 That is the larger size of the "in" picture.
Next over to the right are volume up and down.
Three white buttons come next, the left one selects among 3D modes, the middle one labeled Color Mode lets you toggle between the four preset color modes (Cinema, Bright Cinema, Natural, and Dynamic) or when in 3D, the two 3D color modes. The right button is labeled Image Enhancement. It brings up, and lets you toggle between the five image enhancing modes and Off.
