Hi there

Simply go into your Menu and go to Application Modes and switch it over to Presentation Mode.

Alternatively , reset the Projector.

Charles - does the laptop have an alternate function button that allows for different displays? Similar to the presentation mode, this will manually tell the laptop to use either the native screen, an extension screen (the projector or monitor) or both. Typically this is triggered with the Function (Fn) button and maybe one of the F7 keys at the top. You'll see writing on it that will say LCD/CRT or have a little box like a monitor. Let me know if this helps!

As I am not familiar with Apple this support article below might explain the switching of display outputs available on Apple Mac.

You could be able to enable presentation mode by pressing the "settings" button on the bootom of your display, next to the power button and the "ctrl" and the rotate button. After you press that, your dell control point manager should pop up and then go to the tablet tab on the left and open it. after that, go to the display tab and you should see an option that allows you to turn your presentation mode on.

Need to connect my dell laptop to a large screen projector using a computer video interface for vga and compatible computers I have a delllatitude d610 the interface is an inline2080

I assume you know how to connect the VGA cable and which function key is used to activate the second display. You will have problems if the laptop display size is not supported by the projector. Many older projectors will not work with wide screen laptops.
when you connect the projector, Just press the presentation mode on your keyboard, Fn + (Presentation Key), Sometimes F5 or F8!

Then you will see your desktop on the projector screen.hope this helps

Presentation mode is off...

Hi there

You cannot hook up a PC & Projector with just a USB cable , you have to use a VGA cable for signal ( picture )

The USB cable is just to use the scroll up or down function from the standard remote controll when doing a presentation.

I'm going to guess that you have a wide screen Dell laptop with a 16:10 aspect ratio and a default resolution of 1280X800. The wide screen is great BUT most presentation grade projectors do not have a native (pixel for pixel) 16:10 mode. Instead they still prefer a display input with a 4:3 aspect ratio like your old square CRT or standard definition TV. Why do they prefer a 4:3 input? Mainly because Powerpoint prefers to display a slideshow in a 4:3 mode. Because of this Dell, in their infinite wisdom, created the 'presentation mode' utility in an attempt to automatically convert the VGA output of your laptop from 16:10 to 4:3 on the fly. In my experience this is an annoyance at best and at worst can seriously impact the size and quality of the projected image.

The best thing you can do when you connect to a projector is ignore the presentation mode alert and manually set your laptop's resolution to 1024X768 for an XGA rated projector or 800X600 for an SVGA rated projector. This will cause your desktop to look stretched on your laptop but will give you by far the best projection image.
