Why does my projector suddenly skew my mirrored display?

Projector: Dell MP 3000

Computer: Dell Inspiron 15R

Last night, I tested all my connections and my hardware combo acted and projected the correct image completely satisfactorily.

This morning, for the actual presentation (exact same configuration), the projector displayed my mirrored screen very narrowly, too narrow to use.

When I extended my desktop, the ratio was perfect. But I couldn't get it to work with the mirrored display.

I'm not new to using a projector. I've toggled the resolution, aspect ratio, keystone, restarted both units several times.

No matter what I do, my mirrored screen is way too narrow to use, but not my extended display (which how I made do).

What am I missing?

Update:

Thanks for the answer, but the problem persists despite these measures.

    Hi Monica V,

    When you mirror the display on two different displays, resolution selected for both is same. That is why you get a narrow image while using the projector along with the LCD.

    You may change the resolution of the second display (projector) separately to suit you. Check the link below for steps:

    You may also try updating the video drivers from the link below:

    On the link, enter the system Service Tag and click on ‘Continue’. Select the operating system and it will display a list of available downloads.

    Hope this helps.

    Regards,
