Q. Can an individual participant's slow Internet connection affect the Host's performance or the performance of the entire web conference?
No, participants' individual connections to the Internet and the meeting service only affect the performance and experience of that individual user (unless they are passed Host control during the conference). However, a poor Host connection can impact the overall performance for everyone. Both Host and Participants can pre-check their Internet connection speed using the SpeedCheck provided:
Q. How can I improve the performance of my web conference?
A fast and reliable Internet connection will ensure that your web conference performs well. When you use the Application Sharing feature, change your resolution and color depth to the lowest acceptable settings. If the application being shared is not graphic-intensive, use the Best Speed option in the Select Application to Share window.
Q. Does it help to have a high-speed Internet connection for the Host?
Yes. However, even with a high-speed Internet for the host if a participant is connected through a dial-up Internet service, then the web conference will be slow for that participant.
Q. Are presentations being stored or cached on end user machines?
Depending on how information is being presented in a Web conference, some content is cached and some is not. When presenting published PowerPoint, Word, and Excel documents some JPEG and HTML content will be cached on users' browsers. When sharing applications there the content is not cached in the local browsers. Please be aware that it is not possible to prohibit users from using third party software to capture and store any content which is displayed on their screens during your presentations.
Q. I cannot see the presenter screen, the presentation is to small.
Try using the Fit-to-Window and Full Size buttons. This will allow you to change the size of the presentation. Fit-to-Window will allow the window to fit inside the participant screen(if the host screen has a high resolution the participant screen will scale to that). Full Size will make the presentation expand outside of the participant screen to were the scrolll bars will be visible.
*Note* The host can adjust there screen to allow participants to view the presentation. If the host has a high resolution then they will need to decrease it to allow participants to view the presentation.
*Note*If the participants are using IE then they can hold Ctrl and the Plus sign(Ctrl&+) or Ctrl and the Minus sign(Ctrl&-) to increase/decrease the size of the window frame. You can use the same commands in Firefox.
