Connecting a laptop

Using GTm Family
Last updated April 11, 2018

There are two models of GTm: GTm 5250 and GTm 5140. How users connect a laptop differs depending on which model you have. Each is described below.

On the GTm 5250

When you are in a video call you can share your laptop’s display with the other people in a call, for example if you want to share what you are working on. Additionally, you can share your laptop to present to the room, rather than being in a video call.

To do so, your laptop must be connected to the GTm. Usually, your IT administrator will have left a cable in the meeting room to which you can connect your laptop. If this is not the case, you need to consult your IT administrator, or refer to How to install the 5250. The GTm system includes a number of adaptors to suit different PC video outputs (HDMI, VGA, DVI-D).

Additionally, you can connect an HDMI source to Computer In 1 on the rear of the codec. This can be useful where you have a permanent digital source that you want to connect to the GTm, for example an Apple TV or whiteboard.

When you are in a meeting, you can select to share content using the touchscreen controller. If more than one source is connected, the GTm displays content from the most-recently connected source.

Sharing the display

To share your laptop’s display:

  1. Ensure you have connected your laptop to the GTm codec using the supplied cable.
  2. Make a video call.
  3. On the touchscreen controller, press share my PC screen:

    If you only have one screen, the main view is the PC display and the view of the other participants is in PiP view in the corner of the screen

  4. To change the view you see, use the display tab on the touchscreen controller:

    The display tab is described in greater detail in Using in-call features on the GTm.

Sharing the audio

You can also share the audio from your laptop. To do so, connect the audio-out from your laptop to the audio-in 3.5 mm connector on the rear of the room system. For further information about this, refer to How to install the 5250.

On the GTm 5140

There are three scenarios for sharing content from a laptop:

  • Using a sharing device attached to the laptop to share content and audio
  • Using Skype for Business to present content from your laptop to the GTm room
  • Using Skype for Business to present content from your laptop to a scheduled conference

Each of the above scenarios is described below.

You may also find that you are initially presenting content from your laptop to a room but need to present to a larger group after you’ve begun. In this case, you need to schedule a conference and follow the steps listed in Presenting to a scheduled conference without a sharing device.

Presenting using a sharing device

You can use a sharing device to share content and audio from a laptop. Simply pair the device with the GTm 5140, plugging it into your laptop, and following the instructions given for the device.

If you do not have a sharing device, you can share your screen using Skype for Business.

Presenting to a room without a sharing device

You can share content from your laptop through Skype for Business by calling from the laptop. To do this:

  1. Start a point to point Skype for Business call between the laptop and the GTm.
  2. Click Present at the bottom of the conversation window.
    You can choose to either Present Desktop or Present Programs, depending on whether you want to share your entire screen or a specific window.

    3. For more information on presenting in Skype for Business, refer to the Skype for Business support page .

The laptop can share on-screen content but not audio. StarLeaf recommends that you do not share audio-dependent content.

Presenting to a scheduled conference without a sharing device

You can share content during a scheduled conference by calling in from your laptop using Skype for Business. To do this:

  1. Accept the scheduled conference invite.
  2. When you’re ready to share content with the conference, click Present at the bottom of the conversation window.
    You can choose to either Present Desktop or Present Programs, depending on whether you want to share your entire screen or a specific window.

    3. For more information on presenting in Skype for Business, refer to the Skype for Business support page .

If you are in the same room as the GTm, StarLeaf recommends that you mute the volume and microphone on your laptop while you present in order to prevent any feedback distortion. The laptop can share on-screen content but not audio. StarLeaf recommends that you do not share audio-dependent content.
