How to connect to my Apple TV2?

  1. Make sure your iPad and Apple TV2 are both connected to the same Wi-Fi network
  2. Open 2Screens and click on the Tool icon on the upper right corner to open the Tools menu
  3. Turn ON the ‘AirPlay’ switch and then the app will auto-detect all available Apple TV2 devices
  4. A pop-up message will be shown asking whether to connect with the detected Apple TV2. If multiple devices are detected, you will be prompted to select which one to connect
  5. Answer ‘Yes’ or select the target device, then open a file from the File popup menu and you will see the app starts to mirror screen display to Apple TV2

My iPad is connected to an Apple TV2 but I see nothing being display on the TV screen. Why?


Current version of the app cannot handle Apple TV authentication. If you have set the Apple TV password, please try clearing it temporarily to see if it woks.


How to connect with 2Screens Remote?

  1. Load “2Screens - Presentation Expert” app on iPad, tap on the “Tools” icon on the upper right corner of the screen and switch the option for "Remote Control" to ON
  2. Select “OK” if you are asked whether to turn on Bluetooth (this prompt appears only if Bluetooth has not been activated in the Settings app)
  3. Load “2Screens Remote” app on iPhone and it starts to look for another peer (you would be prompted to turn on Bluetooth if it has not been activated).
  4. Select the iPhone when its device name shows up on the peer list on iPad
  5. On the iPhone, after 5-30 seconds (be patient!) when the dialog box with "XXX would like to connect.” is displayed, tap on the "Accept" button
  6. Connection is established and the status message shown on the iPhone screen will change from “No active connection” to “Connected with XXX”

I followed the above procedures but doesn’t find that the devices see each other. What then?

  • iPhone 3G running on iOS4.0.x always suffers from low memory problem. Rebooting the iPhone may help to free up some memory and thus enable Bluetooth function to run properly. If problem persists, please also reboot the iPad.
  • iOS4.1 can better manage memory usage than 4.0 so it helps to mitigate the effect of low memory on iPhone 3G. Upgrade is highly recommended.
  • All iPhones running on iOS4.0.x usually have Bluetooth instability issues. It is confirmed that upgrading to iOS4.1 (or after) solves all such problems so upgrading iOS is the only and best solution.
  • It is noticed that the Remote app doesn’t work well with multi-tasking on recent releases of iOS 4.3. If one exited from the app and then re-run it after doing something with some other apps, part of the resources of the Remote app may have been forced to handover and thus it can no longer see other Bluetooth devices. Under this situation, please try exiting from the Remote app again and quickly press the “Home” button twice to show all the apps that are left in the background (those in the bottom row). You should then kill the Remote app and some of those which have been run recently to free up more memory before re-loading the Remote app again.

What is the simplest way to open a presentation in the iPad Keynote app using 2Screens?


(Updated 3 Nov, 11) - As now 2Screens - Presentation Expert can act as a WebDAV file server, you may directly transfer files from within the Keynote app to 2Screens by the following steps:
  1. Tap on the “Tools” icon on the upper right corner of the screen and switch the option for “Wi-Fi File Transfer” to ON (requires a Wi-Fi connection to turn on this switch)
  2. Press the Home button to exit to the Home screen, and then complete the subsequent steps within 10 minutes
  3. Open the Keynote app and load the concerned presentation file
  4. Tap on the Tools icon on the menu bar and choose ‘Share and Print’ from the Tools menu
  5. Select ‘Copy to WebDAV’ and enter “http://localhost:8088” to the ‘Server Address’ field
  6. Enter the user name and password if these have been set for the ‘Wi-Fi File Transfer’ service in 2Screens
  7. Click the ‘Sign in’ button and upon successful verification, choose the file format for the file to be transferred to 2Screens
  8. A directory list of the Home Directory in 2Screens is shown on the screen.
  9. Click the ‘Copy’ button to start the file transfer
  10. Upon completion of the transfer, exit to the Home screen and re-open 2Screen app. You will find the file being saved under the Home Directory.

Below is the best solution I know so far (quoted from the review posted by Mr Darren Croton on App Store dated Jan 13, 2011 -- thanks!)

"... Note that I usually prepare my talks in Keynote on the iPad then email the file as a PDF to myself with airport mode on. This places the talk in the outgoing box in mail. I then grab the attached PDF in mail and use the "Open In" option to move it to 2Screens. No need for an Internet connection, and it's a mostly pain free way to move your talk to other apps without needing Dropbox or similar and wasting data..."

The PDF file imported from the Mail app using the above method is stored automatically in the 'Inbox' sub-folder under 2Screens' home directory. Subsequently you can open it directly in 2Screens.


I do not see 2Screens appear in the “Open In” menu when opening PDF files, but see it for other file types. Why?


Firstly, please make sure you have tried scrolling up the list or else you always only see up to 4 apps on the menu.

Besides, the maximum number of apps that can be shown on any iPad “Open In” menu is 10. If you have more than 10 apps that support PDF, you would not be able to see all. You may consider to delete some less-used ones to free up a slot for 2Screens.


Which adaptor and cable are required to enable TV-out so that I can see the iPad display being mirrored onto TV, LCD monitor or projector?


For optimal display quality, you are recommend to get the “Apple VGA adapter” for connecting the iPad to an external screen or projector through a standard VGA cable. Alternatively, if the external screen or projector supports HDMI connection, you may choose to buy the “Apple Digital AV adapter”.

Details of the Apple VGA adapter can be found here on Apple’s web store: http://store.apple.com/us/product/MC552ZM/B?fnode=MTc0MjU4NjE&mco=MTc5MzExNTI . The link to the Apple Digital AV adapter can be found here: http://store.apple.com/us/product/MC953ZM/A?fnode=MTc0MjU4NjE&mco=MjE1Mjg1OTQ .


How to start/pause playback of video file on external screen?


A new mechanism is implemented since v1.7.4 to avoid external screen being locked up after finishing playback of a video file. The original button controls are no longer displayed on the iPad screen, but now one can use the “Slide Show” button (the one with double triangles) on the bottom menu bar to start or pause video play. The “Next” and “Back” buttons can also be used to interrupt video play thus effectively pause video play. To show/hide the bottom menu bar, just tap once on the middle of the screen (middle 1/3 of the screen area).

Please also note that the “Slide Show” and “Next” buttons on the 2Screens Remote app also provide similar functions as those described above so one can now control video playback using an iPhone or iPod Touch.


How to include presenter notes in PDF presentation slides and view them during my presentation?

  1. Open your Keynote or PowerPoint file with the Keynote app on Mac.
  2. Select File > Export > PDF and choose “Export Slides With Notes”.
  3. Check “Print each stage of builds” and UNCHECK all other options (please make sure NOT to check the options for “Include slide numbers” and “Include date”).
  4. Click “Next” to enter file name and select the destination folder for the output PDF.
  5. Transfer the output PDF to 2Screens’ local folder on iPad through iTunes file sharing function.
  6. Open 2Screens app on iPad and make sure “Fast PDF Mode” is turned ON in the “Tools” menu.
  7. Select the PDF from the Folder menu.
  8. After the PDF is loaded, click on the “PN” button on the bottom bar menu to show/hide the semi-transparent yellow area where the presenter notes are shown.

P.S. Starting from recent updates in v1.8, the app is able to show presenter notes in Keynote and PPTX files. However, currently the app is unable to show presenter notes from PPT files.


Why are my presenter notes in PDF files shown as garbage characters?


Currently the app can correctly extract the text of presenter notes written in single-byte characters (i.e. English or Western character sets) only. Presenter notes in PDFs written in double-byte characters (e.g. Japanese or Chinese) cannot be processed correctly.


How can I move the presenter notes to other areas on the iPad screen?

  1. Touch on the “pin” image on the top center of the presenter notes’ yellow box for one second.
  2. Move your finger to drag the pin with the yellow box to any area you want.

Is “Slide Navigator” available for PDFs loaded from other app?


Slide Navigator is not available when a PDF is initially loaded from other apps. However, once a PDF has been loaded by 2Screens, there is a copy automatically saved in the “Inbox” sub-folder under the Home Directory of 2Screens. Slide Navigator will be available next time when you load this local copy. You may also move the file to other sub-folder as you like.


I have large Keynote files which cannot be opened successfully on iPad. Any workaround?


Large Keynote files usually cannot be opened on iPad, even with many other “Reader” apps. With the launch of 2Screens v1.6, now we have a better solution for conducting presentations with very large Keynote files. The app has been modified to support the use of down/up buttons on the bottom menu bar and also the 2Screens Remote app for switching between graphic files in the same directory. So large Keynote file with hundreds of slides can be exported as images (on Mac) and transferred to the iPad for presentation. We find that this effectively solves all problems of slow loading and crashing due to the memory constraints of iPad, though, it takes 2 more steps for the conversion, which are summarized and shown below:
  1. On Mac, export the file by selecting File > Export > Images > Next , and save the output slides to a new folder
  2. Rename this folder to one with a suffix ".app", e.g. myslides.app, so the folder appears as a single file on Mac
  3. Transfer the file to iPad as usual and it appears as a sub-folder in 2Screens.
  4. Images inside the sub-folder can be selected for presentation.
In addition, one can achieve some sort of animation effects, like displaying points one by one in a slide, by selecting the option “Create an image for each stage of builds” before exporting Keynote presentation as images.

With the implementation of our own PDF rendering engine since v1.7, user may also choose to export large Keynote/PowerPoint files to PDFs by the Mac Keynote app before transferring the slides to iPad for presentation as the PDF engine is able to handle very large file effectively.

(From v1.6 onwards, the app is able to prevent the iPad and iPhone being timed out when an external screen is detected, or when bluetooth connection is established when running the apps. The idle timer will also be restored once the apps are stopped. So the above settings are no longer necessary.).

My Keynote file is listed as a directory on the app’s local folder instead of a file. Why?


This happens when the Keynote file was originally created with Keynote'08 on Mac.   The file elements are stored in a folder structure with .key as suffix but the folder is not compressed in the same way as Keynote'09 files.   Mac Keynote'09 app recognizes this format and handles transparently but iPad doesn't.  You may see the same situation if you transfer this .key file to other "Reader" or "Filer" apps.

A workaround is to open this .key file using Mac Keynote'09 app and then save to a new file so it will then have Keynote'09 format.
