ShowMyDesktop Guide

Jump to: navigation, search

ShowMyDesktop is a MegaMeeting feature that allows a Web Conference participant to show his/her screen to the other participants in an online meeting. ShowMyDesktop is Presentation Software built into MegaMeeting conferences that permits the sharing of a conference participant's screen, allowing the participant to show any application to the other participants in the meeting room, while at the same time, broadcasting video and audio. You do not need to upload anything in advance. ShowMyDesktop allows conference members to share their computer screen with others in a meeting, and in so doing, display everything from a spreadsheet or word processing document, to a full screen PowerPoint presentation or product demonstration.

As an example, let's assume that you are a Sales Manager with 15 Sales Reps located in various parts of the country. Your company Widget Inc., is releasing a new widget that is going to revolutionize the widget market in less than thirty days. You prepare a PowerPoint presentation. You now initiate a MegaMeeting Web Conference and use the ShowMyDesktop feature to allow all of your attendees to view your screen. By bringing up the PowerPoint presentation on your screen, you are now sharing your presentation with all 15 of your Sales Reps. Whatever you see on your screen will be displayed to all of the other participants in the meeting.

Installing on a Macintosh

We have recently seen some performance issues with Flash 11 and are recommending using the following instructions for getting ShowMyDesktop to work properly on your Mac.

  • We’ve found that Adobe Flash Player version 11,1,x,x to be the best.
  • We have also found that Google Chrome is the most stable web browser to use.

To uninstall your current version of flash, download this file - Mac Flash Uninstaller

With these three files downloaded and saved to your computer, follow the steps below.

  • Fully quit your web browser
  • Run the Flash Player Uninstaller
  • Unzip the 11,1,102.63 archive
    • Install the file located in these folders - fp_11.1.102.63_archive > 11_1r102_63_32bit > flashplayer11_1r102_63_mac.dmg
  • Open the ShowMyDesktop dmg file and run this package - ShowMyDesktop - Enter Screen - 10 fps.pkg
  • Open Chrome and type “about:plugins” in the address bar without quotations.
  • Click on the + sign in the top right next to Details. If you see a – sign instead of +, continue to the next step
  • Scroll down until you see Flash (2 files)
  • Disable the version in the location “/Applications/Google Chrome Framework.framework/Internet Plug-Ins/Flash Player Plugin for Chrome.plugin”

You’ve completed the steps necessary to get ShowMyDesktop working on your Mac using Google Chrome.

Issues, Fixes and Frequently Asked Questions

How does SMD work? ShowMyDesktop is a one time install on your PC or MAC that will mirror anything that you do on your computer to everyone else in your conference. You can also choose specific applications to show as well (PC version only). Anything you open, run or do on your machine will be seen by the participants, just as if they were standing next to you looking at your monitor!

What does float panels mean? The participants being presented TO will have a panel on the right side of their screen that contains the presenters video, a VOIP control and a chat window by default which can be moved about anywhere in the browser by checking the 'float' checkbox on the left side of the screen. Floating simply means they are free to customize their experience. The person showing their screen can turn off their ability before the presentation as well.

It still says "Install ShowMyDekstop" after reloading the meeting! How do I fix this?' If you reload the meeting and it still says 'Install ShowMyDesktop' in the lower left, please attempt the following:

  • Close the browser, Reboot your computer. Once rebooted, open a new browser and clear the cache (Tools > Internet Options > Delete Temp. Internet Files) - Log back into the meeting and see if it has changed.
  • If it does not change, uninstall the application (see below) and follow step #1 above before attempting to reinstall.
  • Make sure that after the application installs it allows you to click finish. If it DOES NOT, then there are security measures such as firewall/AV installed on your PERSONAL computer or on the NETWORK that need to be turned off.
  • Make sure you also have ADMIN RIGHTS on the computer you are installing to or the installation may be truncated.

My screen is black for the attendees Please make the chosen application active by clicking on it with your mouse.

My screen is grey for the attendees

  • The most common fix to this is to allow the flash player settings.
  • Sometimes the grey screen occurs if you're set to an odd screen resolution. Leave the meeting, close your browser, and check your screen resolution. If it's set to 1366x768, your guests will see a grey screen. Drop it to 1280x768 and try again.

My browser crashes when using SMD on my MAC! What can I do? The MAC ShowMyDesktop function will only support screen resolutions up to 1280x1024. Quit your web browser, go to your System Preferences and click on Displays. Please change your screen resolution and then come back into your meeting.

How do I know what the other attendees are seeing? Simply put, those watching you are seeing everything you do, just as if they were standing behind you physically watching your screen. After you click start, your computer functions and looks the same as it normally does, only now you are mirroring your actions to others. You can open just about any application on your computer and those watching your SMD session will see you do so. Run a powerpoint, an excel spreadsheet, a website or anything else you need to show - Full motion video or streaming media is not recommended however, due to bandwidth and framerate limitations.

I have dual monitors, how will they see my desktop? On multiple monitor setups, only the primary monitor can be seen by those watching your SMD session.

Does SMD support audio as well as video? As of this time, SMD does not support a direct feed for audio when presenting. There is a workaround that will provide you with a way to share sound in addition to video, however. This workaround requires a 1/8" stereo male to 1/8" stereo male cable.

  • Connect one end of the cable to the headphone or line output on your sound card.
  • Connect the opposite end of the cable to the microphone input on your sound card.
    • VOIP must be turned on or the audio will not be sent to guests.
    • The Host will need to execute these steps on the fly, after a meeting has been started with Teleconferencing or a Stereo Headset in use.
