The presentation will displayed using PowerPoint for Windows. If your presentation was created using different software or operating system, please check it with PowerPoint on a Windows PC for changes in the text formatting.

Talks held in the lecture hall HS2, Im Neuenheimer Feld 306, Heidelberg

An IZN technician will help the speaker prepare for their talk.

The speaker should not bring a laptop but bring the presentation on a USB stick formatted for Windows (NTFS, FAT32, exFAT) or send it to

Supported presentation formats are PowerPoint and PDF.

The talk is 'hybrid', that is in front of an audience and with a ZOOM live stream.

In cases where the introducing person cannot be present, an introduction by ZOOM can be arranged, but in person is preferable.

A LOGITECH SPOTLIGHT presenter (laser pointer, slide changer) will be provided. This will show a laser spot on both the projection screen and also in the presentation on ZOOM.

To set a video in a PowerPoint slide to start playing with the forward change button, select the video image, go to the Animations tab, select 'Play' and next to 'Start' choose either 'On click' or 'With previous' (=automatically).

To play a video in a loop: double-click the video, select the Playback tab and click 'Loop until Stopped'.

Talks held online only

The ZOOM platform will be used. Use the latest Zoom software (downloadable here), not a browser.

The IZN ZOOM host will help the speakers prepare for their talks.

Set ZOOM audio settings as follows:

  • Suppress Background Noise: Low
  • Windows only: Audio settings -> Advanced -> Signal processing by Windows audio device drivers: OFF to prevent sound distortion.

Use a cable network connection if possible, not WiFi.

A headset (headphones with microphone) provides the best sound quality for the other participants. Macs need a headset with a USB connection. Some USB headsets do not work well with USB multi-port adapters.

Normally the presentation fills the screen, which can be a problem if you have just the one screen. If you prefer to show your presentation in a window:

  • Microsoft 'PowerPoint':     click the Reading View icon (looks like an open book) at the bottom of the window
  • Or:    Slide Show tab    >    Set Up Slide Show    >    Browsed by an individual (window)
  • Apple 'Keynote':     Play menu   >   Play slideshow in window
  • LibreOffice 'Impress':     Slide Show menu    >    Slide Show Settings    >    Presentation Mode: In a window
  • then:    adjust the window so it fits the presentation and select this window for sharing in ZOOM
  • Don't make the window too small, or the image will be pixelated
  • The presentation window will need a mouse-click to make it active for the keyboard arrow keys to change the slides.

You can use presenter mode (to see your notes and the next slide) on a single screen by sharing the slide part. From 'Share Screen', choose Advanced -> Share portion of the screen (a coloured frame appears). Start the presentation in presenter mode and fit the coloured frame to the slide area.

if the presentation contains sound Share sound in the 'Share Screen' window or Share Computer Sound in the 'More' menu should be active.
