Connecting to a Projector
This support page is about Prezi Classic. If you’re looking for help with Prezi Next, please click here.
BEFORE you connect your projector to your computer:
- Make sure that you are not in Present mode when you connect the projector. Connecting the projector will probably change your resolution and so your prezi may not fit properly into your projected screen.
- It's usually best to resize browser windows to “small” before plugging in a projector, as the resolution change might make it hard to resize your browser window later.
The default setting for most computers will be to "mirror" your computer screen onto the projector. This means that whatever is displayed on your computer screen will be exactly the same on the projector screen. If, for some reason, this is not the setting on your computer, you can change it quite easily. Mac Users can go to System Settings > DisplayWindow Users can find their settings under Control Panel > Display > Display Settings.
Click Present in the upper left corner of the screen while in Edit Mode to start presenting your prezi on your connected projector.
You will see a message like the one below telling you that Prezi Classic is now fullscreen. Click Allow before you start your presentation. If you do not, you will not be able to go through your prezi's path.
Note: Users with a MacBook Pro with Retina display will not see the above message clearly when trying to present from Safari. You will most likely see a message like the one below. This does not allow you to click on the Allow button because you are not able to see it. In this case, please present your prezi from another browser such as Mozilla Firefox or Google Chrome.
Unfortunately, most laptops are widescreen, but most projectors use the 4:3 aspect ratio.
You can overcome this by setting a guide to your Prezi Classic canvas that shows you the exact dimensions to work to for each common aspect ratio.
This is an advanced feature, and it works likes this:In “Edit” Mode, click the cogwheel in the upper right corner of the screen. Select the ratio you wish to display your prezi in. You can also tap CTRL+SHIFT+M (COMMAND + SHIFT + M on Macs) to switch between the 4:3 and 16:9 ratios or to turn the aspect ratio guide off.
Once you have selected the right aspect ratio in “Edit” Mode, change to “Present” Mode, you’ll see a black border around your prezi. This reveals exactly what will appear when presenting on a screen of the corresponding aspect ratio. The black edges will not appear when presenting on a screen that has the selected aspect ratio, for example, if you choose 4:3 in “Edit” Mode and present on a normal 4:3 projector. This is a great way to make sure that you know precisely what your audience will see.
Your settings will be remembered the next time you open your prezi but can be changed at any time using the keyboard shortcut above.
Tip: In order to take advantage of this feature to its full extent, you can create frames that have a set aspect ratio. This is very easy to do, just hold the SHIFT key when you drag your cursor to create a frame.
Note: Prezi for iPad uses a 4:3 ratio by default but also supports 16:9.
