Hi Bob, welcome to the 123PPT Community and PowerPoint Forum.

Displaying your PowerPoint presentation on one monitor while you view presentation notes on your own monitor is actually quite a common problem.

You can take a look at our PowerPoint Tips and Tricks for PowerPoint and Video.

http://www.123ppt.com/powerpoint-tutorials/powerpoint-tips-video.asp

You'll find a step by step guide on how to have you're notes on your laptop and your presentation running on the projector or plasma screen for example without the audience viewing your presentation notes.

Any time Bob.

Good luck with your presentation tomorrow. You're audience will never know that you're secretly reading all your notes off your laptop

Hi Ravinder, welcome to the 123PPT Community and the PowerPoint Forum.

It may be that your screen resolution is much higher than that of your projector. Often projectors support much lower resolutions than monitros and laptop screens. So if your actual display card setting is set higher than your projector, for example to 1920x1080 and your proejctor's maximum screen output is 1280 x 1024 then when you attempt to display this resolution on your projector you will only see a black or blue screen as the projector cannot accept a signal of such high resolution.

To resolve this Ravinder, right click on your desktop and select Properties.

Select the Settings tab from the Display Properties dialog box. If you are using a dual display, you will see Monitor 1 and Monitor 2. Select each monitor and reduce the screen resolution slider of both down to 1024x768. and press the Apply button before clicking Ok.

Follow the steps again, and if you still are unable to view your dual display simply repeat the steps above selecting 800x600 instead as the screen resolution for both monitors.

In some case, older projectors cannot display screen resolution greater than 800x600, and certainly if for example you are outputting to an analogue tv for example you must select 800x600 as the screen reoslution.

Hope this helps.
