Frequently Asked Questions

What are my options for presenting with the video wall?

Presenters can choose to present using either:

The connected Windows 10 PC
Presentations can be loaded onto the PC from the internet or from a USB thumb drive. Windows PowerPoint is installed on the PC. This is the preferred way to take advantage of the full resolution of the Video Wall (5,760 x 3,024 pixels).

Their own device through HDMI connection and a 'frame grabber' software
While it is convenient to present from a laptop, resolution will be limited to the resolution of the laptop screen so may appear 'pixelated.' A USB-C adapter for newer Mac laptops is available from the Library. A long HDMI cable that reaches to the far end of the table is also available upon request.

How do I use the HDMI cable to present from a laptop?

1. Click the icon in the Windows Taskbar.
