Question about Panasonic PT LC75U Multimedia Projector
When I hook up my projector to my computer and restart a message appears on computer screen telling me presentation mode is off. What does that mean and how do I fix it??
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.

Most of the time the problem resides between the chair and the keyboard. Yes! indeed. By rule of thumb the sceen resolution and projector must of the same ratio for the proper display. Newer Dell projectors can adjust this automatically with wide screen dell laptops. Please make sure to press fn(key) and F7 on dell wide screen laptops before connecting the projector. This will enable the screen compression for proper display!

You can turn presentation mode on through the dell quickset software.
Go to display settings in dell quickset and you can turn on presentation mode.
