If you can bring up the settings menu, go to the magnification setting and reset to 1X, you won't see part of the menu either and have to guess at the setting, but it will pop back to full screen when you get it. It will revert so memorize where the setting is and how to fix it when you can't see the menu.

Mine does the same thing but i can see the whole screen it's just half height full width, above solution about zooming to 1X is what i've been doing to fix it for the last 6 months, needs to be done every time I turn the power back on. Anybody know of a more perminate fix?
Now my power supply has gone have the projector in pieces, found a failed on transistor but because it's over heated can't read of it what type it was....
Already replaced two blown diodes in the main H-bridge
Looks like one coil will need rewinding.
If anybody has one in pieces I would be great if you can help me work out what the blown transistor was.

Epson adjustment

The projector has a 4:3 display panel (1024x768 pixels). When you send information to display in 4:3 mode, the picture spills over the top and bottom of your screen.

When you send stuff in 16:9 mode, the projector shows this on the screen as 16:9, but the panel area is still 4:3. This can't be altered. So the unused part of the 4:3 panel above and below the image still bleeds some light through. That's what you are seeing.

You can mask some of this effect by using light absorbing material such as black velvet above and below the screen. Alternatively you can replace the projector with one designed for home theater use which has a 16:9 panel to match the shape of your screen.

Only showing background of computer

Check your computer's (I bet blind that it's actually a laptop) video output settings. It's most likely defaulted to "extended" or "dual screen" mode... which can be useful in some cases to e.g. let you set up a powerpoint that shows an unmolested image of the slides on the projector whilst you control it with a rather more option-heavy display on the laptop screen.

However if you really want the projector to just directly show what's on the internal screen itself, look for a mode called "Clone", "Twin" or "Mirror" (or something with a similar meaning)... or just cycle through them until you find one that works.

Mind that most projectors now are both lower resolution and have a different shape output to a typical laptop, so expect that one or other of the displays will end up seemingly distorted somehow, either stretched/squashed to fit or with horizontal/vertical letterboxing (black borders). It's quite likely that your internal display will end up being crunched down to match whatever the projector reports as its native resolution... do not panic, it's not a fault, this is fairly expected behaviour. At least, so long as it goes back to normal when you unplug the projector, of course.

Unfortunately I can't predict which of the above will actually happen, as every manufacturer has a different in-house standard for default behaviour, and the combination of two devices potentially from different marques being connected together only multiplies the possibilities. Just muddle through as best you can ;-)

My dell d630 won't recognize the infocus lp70+ remote control and I can't advance my power point slides?

Here's what the User's Manual says:

Using the Remote Control

To advance PowerPoint slides with the projector's remote, you

must connect the USB cable on the projector's computer cable to

the computer. See page 8 for more information.

Point the remote control at the projection screen or at the front or

rear of the projector (not at the computer). The range for optimum

operation is about 30 feet. If you point the remote at the

projection screen, the distance to the screen and back to the projector

must be less than or equal to 30 feet. For best results, point

the remote directly at the projector.

If you are displaying presentations in Microsoft® PowerPoint®,

you can use the remote's Previous and Next buttons to navigate

through your presentation while in Slide Show mode.

Projector does not display laptop screen

Many laptop computers do not automatically turn on their external
video port when a projector is connected. On many laptops, the activation function key is labeled with an icon or the text CRT/LCD.

Try the Function Key with the Icon of a monitor to enable the external video port.

If that does work, look at the settings on the projector using the buttons on the top.

Check the "Default Source"

Default Source toggles among Computer 1 analog, Computer 1 digital, Computer 2, and Video. This determines which source the projector checks first for active video during power-up. Highlight Default Source and click the left or right mouse button to toggle
among the options.


Hi yupar

Try holding down the Fn ( function key ) on your keyboard and pressing in the F-row of buttons the one with either 1 or 2 screens on it.


Sharp XR10X Screen size

depending on the age of your computer, some of the older video cards in XP only will allow you to show video in 600x800 resolution. When you want to show video go ahead and change both of your display properties (both the primary and the secondary) to 600x800. See if that works.

If that is not what you are refering to go right click on your desktop and look for the properties or settings of your graphics card. it may say graphics properties . In that area there will be tons of options like (when showing video only show it on the secondary monitor) play around with the different settings on your graphics card.
Good luck
