Computer-based presentations are now so commonplace. We take it for granted that our equipment will work properly. Most times, it does but you can save yourself from a bumpy ride by making sure everything is turned on and connected properly before pressing ‘enter’ – or hitting that one green button to start your presentation. If the projector shows an empty screen for your presentation.

Projector Input Source:

Data projectors or TVs that are often used with multiple input sources may not automatically show the source of your computer. These types of data projectors/TVs typically have an input button on top of the projector, or on the side or back of the TV to change the input source. On older model data projectors/TVs you may also need to go into the projector/TV’s settings menu to change the input source.

 Power Switched On:

It’s interesting how easy it is to overlook certain little details. Even when we practice good computing habits. An instance would be disconnecting your laptop from power when you’re not using it, unlike a projector that does not need to be plugged in in order for it to work. When you try and turn a projector on without plugging it into an outlet first, nothing will happen. The reason: projectors need electricity before anything else can work with them.

So make sure the cord is plugged into the wall outlet if the projector won’t turn on. As you read through these important tips and tricks, take notes of things that seem like they might be confusing at first but have become more clear as a result of being made simpler.

Projector Standby Mode On:

When you plug your computer into the projector after someone has just used the device, sometimes there’s an issue with your presentation. It could be something to do with the projector being in standby mode, causing the fan of your desktop computer not to work as it should. Standby mode is normally used for televisions and projectors so that they don’t overheat or go to sleep when not being used for a time.

Projector Cover Loose:

When moving your data projector or traveling with it, there are a few things that you need to make sure it’s being stored and transported properly. Some of these things include: When moving your data projector, ensure the screen is also covered when possible.

 Display toggle:

Laptops have multiple display mode options. The most common are: 1) laptop display only, 2) external display only, 3) duplicate the laptop display on the external display, and 4) extend the laptop display onto the external display. The computer may not be in a mode to correctly show the presentation on an external screen.

When choosing a model for your presentation, you need to decide whether you will use the Duplicate Displays mode or the Extended Desktop Mode. Duplicate Displays is a common choice among presenters because it allows their laptop and the projector/TV to have similar content. This means that if they put their next slide on the left side of their projected image, then it will also be on the left side of their laptop’s image. If you want to open Presenter View in PowerPoint, it must be set in Extended Display Mode. However, this doesn’t mean you always want to present using this option.

You need to make sure both your computer and your projector are compatible with this mode change as well as have sufficient hardware capabilities. This can be deceiving and unreliable at times so I advise against relying on it entirely. The article above presents different options that help with providing a solid foundation for your speaking notes – regardless of which display mode you choose.

Now that you have your laptop connected, you will want to change the display settings. Some laptops default to the extended mode when they are connected to projectors or TVs. This means that your laptop will extend its own display onto the larger screen via an HDMI connection. Windows 8 and 10 allow users to easily toggle between extended and duplicate modes which involve pressing the Windows Key and P key at the same time.

You can now use your arrow keys to select one of those options, press Enter, read below on how to change between modes under Windows 7, and then wait five-ten seconds before toggling through the other modes using the same steps as above provided you are using a laptop that comes with a function key and it’s labeled Fn so that pressing this special key (held down while pressing another special function key) will enable you to choose a model.
