EPSON PowerLite 7800p Projector 5/03 EPSON PowerLite 7800p Projector - 3 Positioning the Projector Follow these guideline when deciding where to place the projector: ❏Place the projector on a sturdy, level surface. ❏Make sure there is plenty of space for ventilation around and under the projector. Do not set it on top of anything that could block the vents under the projector. ❏Make sure the projector is within 10 feet of a grounded electrical outlet or extension cord. Image size increases with distance, but varies depending on how you’ve adjusted the optical zoom and other settings. It’s best to place the projector directly in front of the center of the screen, facing the screen squarely. If it isn’t placed this way, the image will be “keystone” shaped, instead of rectangular. If you place the projector below screen level, you’ll have to tilt it up by extending the front adjustable foot. This also causes the image to lose its rectangular shape. To correct distortion, see “Adjusting the Image Shape” on page 8. Calculating Image Size and Projection Distance Use the formulas below either to find out how large your image will be when you know the distance from the projector to the screen, or to find out how far from the screen to place the projector if you want an image of a certain size. Since the size of the image can be changed by rotating the zoom ring, formulas are given for calculating both the minimum and maximum sizes. Note: The formulas given here are for when the projector is placed flat, without tilting it up at the screen. If you tilt it up by extending the feet or use electronic keystone correction, your image size may vary. Standard Lens To determine the diagonal size of an image (in inches) when you know the projection distance: ❏Maximum diagonal size = (((2.54 × projection distance) / 100) × 36) + 2.13 ❏Minimum diagonal size = (((2.54 × projection distance) / 100) × 26.84) + 1.29 To determine the projection distance (in inches) when you know the diagonal size of the screen image: ❏Maximum projection distance = (((diagonal size – 1.29) / 26.84) × 100 / 2.54 ❏Minimum projection distance = (((diagonal size – 2.13) / 36) × 100 / 2.54 Middle Throw Lens (V12H004M03) To determine the diagonal size of an image (in inches) when you know the projection distance: ❏Maximum diagonal size = (((2.54 × projection distance ) / 100) × 27.42) + 1.49 Minimum diagonal size = (((2.54 × projection distance) / 100) × 20.48) + 1.1 To determine the projection distance (in inches) when you know the diagonal size of the screen image: ❏Maximum projection distance = (((diagonal size – 1.1) / 20.48) × 100 / 2.54 ❏Minimum projection distance = (((diagonal size – 1.49) / 27.42) × 100 / 2.54 Long Throw Zoom Lens (V12H004L05) To determine the diagonal size of an image (in inches) when you know the projection distance: ❏Maximum diagonal size = (((2.54 × projection distance) / 100) × 20.4) + 1.93 ❏Minimum diagonal size = (((2.54 × projection distance) / 100) × 15.23) + 1.45 To determine the projection distance (in inches) when you know the diagonal size of the screen image: ❏Maximum projection distance = (((diagonal size – 1.45) / 15.23) × 100 / 2.54 ❏Minimum projection distance = (((diagonal size – 1.93) / 20.54) × 100 / 2.54 2.5 to 3.5 ft 5.3 to 7.2ft 27 to 36.5 ft approx. distance from 60” screen TBD Overhead ViewProjector Screen
EPSON PowerLite 7800p Projector 4 - EPSON PowerLite 7800p Projector 5/03 Connecting the Projector You can connect the projector to three computer sources or four video sources—up to a total of four sources altogether. You can include an independent sound channel for each source. (See the Quick Setup poster or the User’s Guide for complete setup instructions.) Note: The preview feature lets you see all the sources at a glance, so you can easily switch among them. See page 5. Types of Connections The following types of connections are possible, depending on the kinds of signals your equipment generates and its available output ports. Note that the projector’s Computer and BNC ports accept a variety of input signals. If you’re connecting to one of these ports, you’ll need to make sure that the correct input signal setting is selected, or your image won’t display properly. To change the input signal setting, do the following: 1. After turning on the projector, press the Menu button. The menu screen appears. 2. Select the Setting menu. 3. Change the Computer Input or BNC Input setting as needed to match the signal generated by your computer or video equipment. (See the User’s Guide for more information.) You can also cycle through the settings by repeatedly pressing the source button for your device on the remote control. Playing Sound Through the Projector You can play sound through the projector’s speaker system or you can attach an external speaker system. Two types of audio cables are included with the projector: ❏If your computer or video equipment is connected to the Computer or DVI port, use the stereo mini-jack cable. ❏If your equipment is connected to the Video or S-Video port, or to the BNC ports, use the RCA-style audio cable. Using the Remote Control as a Wireless Mouse If you’ve connected a computer to the projector, you can use the projector’s remote control as a wireless mouse by connecting the USB cable that came with the projector. The wireless mouse function is supported on systems with a USB port running Windows XP, 98, 2000, or Me; or Macintosh OS 8.6 to OS X 10.2. See the User’s Guide for more information. Viewing Images on an External Monitor You can use an external monitor to display images from any connected computer source. This lets you view your presentation close-up, as well as on the projection screen. Note: Some LCD monitors may not be able to display the image correctly. If you have trouble displaying the image, connect a multiscan monitor. If you’re projecting computer images, make sure the computer’s refresh rate is set to 65 Hz or greater. To use an external monitor, connect it to the projector’s Monitor Out port, as shown: Computer equipment Output signal Required cable Analog RGB videoVGA cable BNC cable VGA-to-BNC cable DVIDVI-D dual-link cable (DVI-to-DVI or DFP-to-DVI available from EPSON) Video equipment Output signal Required cable Composite video RCA video cable S-Video S-Video cable Component video— NTSC (YCbCr)BNC cable Component video— HDTV (YPbPr)BNC cable RGB videoVGA cable BNC cable External monitor
EPSON PowerLite 7800p Projector 5/03 EPSON PowerLite 7800p Projector - 5 Follow these guidelines when using an external monitor: ❏The monitor displays the currently selected computer source. Press the Preview button on the remote control if you want to display all the active sources at once (see “Previewing Image Sources” on this page). ❏If you want, you can view (or preview) images on the monitor while the projection screen is darkened by pressing the A/V Mute button. ❏You can also view images on the monitor while the projector is in standby mode (plugged in but not turned on). Set the Standby Mode setting to Network ON in the Advanced1 menu. Displaying an Image If you turn on your computer or video equipment before turning on the projector, the projector automatically selects the connected source. If you turn on the projector first or you have multiple sources connected, you may have to switch to the desired source manually (see “Selecting the Image Source” on this page). Turning On the Projector 1. Remove the lens cap. 2. Plug in the projector. 3. Wait a few seconds until the P power light stops flashing and turns orange. 4. Press the red P Power button on top of the projector or on the remote control. Note: If you’re using the remote control, make sure batteries are installed and the power switch on the side of the remote control is turned on. The P power light flashes green as the projector warms up, and an image begins to appear after about 30 seconds. When the P power light stops flashing and remains green, the projector is ready for use. Wa r n i n g : Never look into the lens when the lamp is on. This can damage your eyes.5. If you’ve connected a Windows-based computer to the projector, you may see a New Hardware Wizard saying your computer has found a plug-and-play monitor; if so, click Cancel. Selecting the Image Source If multiple devices are connected to the projector, you can use the Source buttons on the projector or the remote control to switch from one source to another: ❏The projector has two Source buttons. Use the Computer/DVI button to switch between equipment connected to the Computer and DVIports. Use the Video/BNC button to switch between equipment connected to the Video, S-Video, and BNC ports. ❏The remote control has five Source buttons you can use to switch between equipment connected to the port identified on each button. (The PowerLite 7800p does not support EasyMP. ™ ) You can preview all sources to help you select the desired source, as described below. Note that the Computer and BNC ports can be set up to use different input signals (for example, Analog RGB or RGB Video)—so if you have equipment connected to one of these ports, it’s important to select the correct signal to match the equipment you’re using. You can change the input signal settings using the projector’s menu system as described in “Types of Connections” on page 4. Previewing Image Sources You can use the Preview function to help you select the image source when you have connected multiple sources to the projector. 1. Press the Preview button on the remote control. Power button Preview
EPSON PowerLite 7800p Projector 6 - EPSON PowerLite 7800p Projector 5/03 You see the currently selected source displayed in the main window, as shown below.

If no equipment is connected to a port, or if there is no incoming signal, the preview window for that source appears blank. Note: Movies are displayed as still images on the preview screen. 2. Press the corresponding Source buttons on the remote control to switch to the desired source. Or press the ESC button to exit the preview screen without switching sources. Note: A red highlight surrounds the preview window for the currently selected source. You can use the pointer button on the remote control to highlight a different source, and then press Enter to display it. Troubleshooting Display Problems You Can’t Project an Image If you see a blank screen or a blue screen with the No Signal message, try the following: ❏Make sure the cables are connected correctly. ❏Make sure the P power light is green and not flashing and the lens cover is off. ❏If you’ve connected more than one computer and/or video source, you may need to press one of the Source buttons on the projector’s control panel or the remote control to select the correct source. (Allow a few seconds for the projector to sync up after pressing the button.) ❏If you’re using a PC laptop, press the function key on your keyboard that lets you display on an external monitor. It may be labeled CRT/LCD or have an icon such as . You may have to hold down the Fn key while pressing it. Allow a few seconds for the projector to sync up after changing the setting. The Projector and Laptop Don’t Display the Same Image If you’re projecting from a laptop, and you don’t see the same image on the projection screen and on your computer screen, follow these guidelines. If you’re using a PC laptop: ❏On most systems, there’s a function key that lets you toggle between the LCD screen and the projector, or display on both at the same time. It may be labeled CRT/LCD or with an icon such as . You may have to hold down the Fn key while pressing it. Allow a few seconds for the projector to sync up after changing the setting. ❏If the function key doesn’t permit you to display simultaneously on both screens, you should check your monitor settings to make sure both the LCD screen and the external monitor port are enabled. From the Control Panel, open the Display utility. In the Display Properties dialog box, click the Settings tab, then click Advanced. The method for adjusting the settings varies by brand; you may need to click a Monitor tab, then make sure the external Monitor port is set as your primary display and/or enabled.

EPSON PowerLite 7800p Projector 8 - EPSON PowerLite 7800p Projector 5/03 Adjusting the Image Shape In most cases, you can maintain a rectangular image by placing the projector directly in front of the center of the screen with the base of the lens level with the bottom of the screen. Even if the projector is slightly tilted (within a range of 40° up or down), the projector’s automatic keystone correction function detects and corrects vertical keystone distortion. It takes about one second after projection starts for the image to be corrected. During this time, a vertical keystone correction gauge appears on the screen. If your image is still distorted, you can correct it using either of these methods: ❏If the image has two parallel sides but is wider on the top, bottom, left, or right, you can correct it using the Keystone keys on the projector’s control panel or the Keystone menu (see “Using Keystone Correction” below). ❏If the image is trapezoid- shaped (no two sides are parallel), you can adjust its shape using Quick Corner ™ as described below. You cannot use both keystone correction and Quick Corner at the same time. Using Keystone Correction To adjust your image when it is wider on one side, do one of the following: ❏Look at the shapes of the icons on the projector’s four Keystone buttons. Press the button whose icon is the opposite shape of your screen image. Continue pressing the button until you are satisfied with the shape of the image. Note: The image will be slightly shorter after adjusting. If it’s important to maintain the correct aspect ratio, use the menu system to perform keystone correction, as described below, then adjust the Height setting as needed. ❏Press the Menu button on the remote control, select the Setting menu, and press Enter. From the Setting menu, select H/V-Keystone in the Keystone menu and press Enter. Select V-Keystone (for vertical keystone distortion) or H-Keystone (for horizontal keystone distortion) and press Enter. Use the pointer button on the remote control to adjust the keystone setting as needed. Using Quick Corner Use Quick Corner to correct the image shape when it’s uneven on the top and bottom, or on all sides. 1. Press the Menu button on the remote control (or on the projector’s control panel). 2. Select the Setting menu and press Enter. 3. From the Setting menu, select Keystone and press Enter. 4. Select Quick Corner and press Enter. You see this screen: 5. Press the Enter button to select the corner you want to adjust. 6. Use the pointer button on the remote control (or the arrow buttons on the projector) to adjust the shape. 7. Repeat steps 5 and 6 as needed to adjust any remaining corners. 8. When done, press the ESC button on the remote control to exit the menu system. If Quick Corner remains selected in the Keystone menu, the Quick Corner screen appears whenever you press the projector’s Keystone buttons. You can then follow steps 5 through 8 above to correct the shape of your image, or press ESC to exit Quick Corner.

EPSON PowerLite 7800p Projector 5/03 EPSON PowerLite 7800p Projector - 9 Correcting Computer Images If you’ve connected a computer and the image doesn’t look right or fit properly on the screen, press the Auto button on the remote control (or the Auto/Enter button on the projector’s control panel). This automatically resets the projector’s tracking, sync, resolution, and position settings. Note: You must be projecting an image for this button to have any effect. The Auto button works only with computer images. Also, make sure the correct Computer or BNC Input option— such as Analog RGB—has been selected in the Setting menu. Alternatively, you can cycle through the input settings using the corresponding source button ( Comp, BNC) on the remote control until you see your device. If vertical stripes appear in the projected image and the Auto button doesn’t correct the problem, hold down the Shift button on the projector’s control panel while pressing either the Tracking + or the Tracking – button. If the image appears fuzzy or flickers and the Auto button doesn’t correct the problem, hold down the Shift button while pressing either the Sync + or Sync – button. Note: Also make sure you have selected the correct Computer or BNC Input option in the Setting menu for your computer. See the User’s Guide for more information. Projecting Images Without a Screen Even if you don’t have a screen, you can project images onto surfaces like blackboards and colored walls without loss of image color. Your projector has a sensor that measures the conditions of the projection surface and automatically adjusts the colors and shading of your image. For example, if you’re projecting onto a surface near a window, your image appears clear and well-defined rather than faint. Making Initial Color Corrections Press the Wall Shot button on either the remote control or the projector’s control panel while projecting an image. Wall Shot’s status appears in the upper right corner of your screen. Then you see a sequence of colors flash for approximately five seconds while the sensor measures the conditions of the projection surface and adjusts the image. Note: If the status message indicates that Wall Shot is off, press the Wall Shot button again to turn it on. When you turn off the projector, it stores the correction values obtained by the last Wall Shot measurements. This is useful if you’re projecting against the same surface and under the same conditions. To retrieve these corrections, just press the Wall Shot button again while projecting an image. Adjusting Color Corrections for a New Surface Follow these steps to adjust the correction values if you’re projecting on a new surface or in a new location: 1. Press the Wall Shot button on the remote control or projector while you’re projecting an image. Wait for the Wall Shot status screen. 2. Press the Wall Shot button until you see Wall Shot Readjustment on the status screen. You see a sequence of colors flash for about five seconds as the projector adjusts the color correction values for the new projection surface. Auto button Wall Shot ON
