A Barco Unisee video wall is available for presentations & scientific visualization in the Wolbach library.

Hardware Configuration

• An array of 3 x 3 monitors creates a 5,760 x 3,024 pxl seamless display (13.75' diag.), with almost no black space between each monitor (55" diag. screen, 16:9 aspect ratio, 800 cd/m2 brightness ea).
• A tenth monitor, located on a rolling cart, adds a control screen and access to keyboard, mouse and docking of a laptop, etc.
• Two computers can drive the video wall (one at a time, though):
  1. a quad-core PC (16GB memory, 256GB primary and 2TB secondary SSD storage, NVIDIA quad-GPU and a frame grabber) running Windows 10 Entreprise, pre-configured by the vendor, Barco, and
  2. a mid-range server running Linux (Dell Precision 7920, dual 16 cores CPU, 256 GB memory, 8 TB of NVMe SSD storage and NVIDIA quad-GPU), running Rocky 8.5, configured specifically for visualization.
• The PC has a frame grabber that takes any HDMI video input (like a laptop) and can display it on the video wall.

Specific Software

In order to maintain a working system, users will not be given elevated privileges.

Usage, Access & Liability Policies

1. Smithsonian's Acceptable Use Policies SD931;
2. Harvard Acceptable Use Policies (i.e. Policy, Policy Statements, and other links on that page);
3. the Wolbach Library Guiding Principles; and
4. common sense.

The Wall is accessible during the library operating schedule, namely weekdays between 9am and 5pm.
If you wish to use it outside this schedule, make sure that you have scheduled access time: that request will trigger an exception to the procedure that automatically turns off the Wall outside this operating schedule.

Access Methods

To use the Wall in "Presention" mode:

1. you will need to schedule your presentation by directly emailing the library library@cfa;
2. someone from the library (or the CF) will give you access to the PC;
3. your presentation must be in a format that the PC can display; or
4. you can use your own laptop, if it can generate a high resolution HDMI output.

1. request an account on either or both of the computers;
2. schedule a training session; and then
3. schedule access time, by emailing the library directly (library@cfa).
