Screen and LCD Projector Resolution

With a classroom LCD projector

   These pages are designed for an LCD projector resolution setting of 1024 x 768 pixels (a 4:3 aspect ratio) and the typical classroom pull-down screen size - about 60 inches wide. That setting will show the pages using as much as possible of the screen's horizontal and vertical size. Be sure to put the display in full screen mode (F11 key on most computers).

   Setting the projector resolution to wide screen format (16:9 aspect ratio), and fitting the wider display on the same size classroom screen, reduces the vertical height of the display on the screen.

   If you are showing DVD or other resources made for a wide screen (16:9) format, you can adjust the setting to match if needed. Some projectors will automatically adjust to the proper resolution.

   Please talk with your school technology specialist if you need help setting up or adjusting your classroom A/V and computer equipment. It can get tricky!

On a desktop or laptop

If you and your students are using this site on desktop computers or laptops, you may still find it best to check and adjust your screen resolution to give the best view of the pages and images on this site.

Go to the control panel on your computer, and find the display resolution setting adjustment.

For a 4:3 aspect ratio screen, pick the 1024 x 768 pixels choice. The photo below will fill the screen almost completely when you put the display in full screen mode (F11 key on most computers).

For a typical wide screen (16:9 aspect ratio) monitor, pick 1360 x 768 pixels or 1366 x 768 pixels. The photo below will fill the screen almost completely top to bottom, but there will be some margin space on the left and right sides. Be sure to put the display in full screen mode (F11 key on most computers).

You can use your keyboard's zoom in / out controls instead if you prefer not to change your settings.

On a large flat screen HD (high definition) TV screen

HD flat screen TV sets come with a wide variety of screen resolution settings. These sets have become much less expensive in recent years, and are increasingly being used instead of LCD projectors in classrooms.

One standard HD resolution is called 720p, with a screen resolution of 1,280 x 720 pixels. That is a good choice for displaying these and most other web pages. Many newer TV screens, however, default to an even higher resolution. You can adjust either the screen resolution, or just use the zoom in / out controls, to size the content for best visibility.

   At a projector setting of 1024 x 768 pixels, the photo below and the other resources on this site will be a good fit on your classroom screen. Adjust your projector settings, zoom lens, and position so the photo fills your screen almost completely, and is not cropped or spilling off-screen at the top or bottom. Be sure to put the display in full screen mode (F11 key on most computers).

   The photo should not appear to be stretched out or compressed, either vertically or horizontally.

   Check that students in the back and side corners of your room all have a clear view. No one will be interested in content they can't see (and hear) well. A sense of show business is good business in today's classrooms, because that really will help engage your students!

This photo is 975 x 713 pixels, so it fills a screen at a projector setting of 1024 x 768 pixels just right,
leaving a little of the background framing it around the sides, top, and bottom. Be sure to adjust
the zoom lens and focus on your projector to make the projected image large and clear, so
students in all parts of your room can see it easily.
