Is it possible to connect a projector and a flat-screen tv and control both with a laptop computer? (the flat screen would be used instead of a projection screen)


when connected at the same time, you need an active signal splitter, or
connect the flat screen to the monitor out terminal of the EIP-2500.

I have a Dell laptop ready to go with my first Power Point presentation. I check the projector out from the library and there are no instructions. I googled instructions and tried the advice: Push Fn and...


Look for the F-key with a square/icon of a laptop. Press FN+This button until you see your screen display show that it will be using your LCD + the output on your computer. Remember you need to hook both the VGA or HDMI out to the projecter as well as the USB cable.

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.

Can't get power point to project on sanyo pro xtrax


sounds like it could be a problem with the output resolution of the computer. some projectors will not be able to display anything higher than 800x600, and most computers now can output at a higher resolutions. check the limits of the projector and change the the display on the computer by right clicking on your desktop and going to properties >settings >screen resolution.

We have new DuKane LCD Projector Model 8755J that will not keep the screen projection from the Dell Desktop computer it is attached. The screen flashes up, but does not stay connected to show the screen....


give it to me its broken.
jk
but no really, its broken. you might try an alternative input, but short of that its a pickup sensor issue- not seeing the signal.

replace the master circuit board in it, or just buy a new one.

Delay/ whitescreen when projecting video from laptop


1.
Connect the external display port on your laptop computer to the projection system, and then turn on the projector. For information about connecting external devices to your laptop, see the documentation for your laptop computer.
1.
Set the display resolution of your laptop computer to match the resolution of the projector system. First, on your laptop, open the Display Properties dialog box by using the Display icon in Control Panel, and click the Settings tab. Then, in Screen resolution area, move the slider to adjust the display resolution of your laptop. If you don't know which setting to choose, try 800 x 600 pixels; this is a common setting for many projector systems. YOURS sounds like 640x840.
3.
If you have audio in your presentation, connect a cable from your laptop's audio output jack to the audio input jack on the projector, and then test the volume by playing a file that contains sound.
4.
Start the Player on your laptop. If you want to only display the Player on the big screen, and not the desktop background, maximize the Player or set it to play your video using the entire screen (full-screen mode).

Rolling picture


Have you tested the source machine on another TV or projector. The picture might be rolling before it gets to the projector so you need to verify whether it is the source machine or the content then you might be able to determine if it is the actual projector. Sounds like the vertical sync has got lost somewhere.
Hope that helps. Also we can supply lamps for this model if you ever need.
Re your Sharp XV 9000S We are able to supply replacement lamp+housing delivered (excluding local your local taxes) for $US342 as we ship internationally and also the same with our revolutionary ICE Digital Daytime projection screens.
