Tech Info: GCC 205

Please use this page as a reference if you need to use the monitors, sound system or instructor podium in GCC 205.  Please turn off monitors and other equipment when finished using it.

[error]Do not sit on the rounded end of the tables.  It will not support your weight.  If you break a table, you will be charged for the repair.[/error]

Monitor Video Routing

The four table monitors and instructor monitor, along with the instructor computer, podium laptop connection and Blu-Ray player are all connected to a matrix-style router located in the corner of the room.  This allows monitors to be switched independently or together to one source.  The five monitors are destinations on the router.  The instructor computer, podium laptop connection and Blu-Ray player are all sources on the router.  Use the following table to convert the devices into numbers on the router.

[notice]Note: monitors are described as you are standing at the front, looking towards the back of the room.[/notice]



 Number  Destination


 Podium Computer

 Left side, near table monitor


 Podium Laptop Connection

 Right side, near table monitor


 Left side, far table monitor


 Right side, far table monitor


 Podium monitor



The most common operation is to switch all of the monitors over to one source.  To do this, press and release the ALL button on the router, then press the number for the source desired.  ALL then the 1 button will switch all monitors over to the podium computer.  ALL then the 2 button will switch all of them over to the podium laptop connection.

[important]When using a laptop at the podium, the highest quality image will be achieved by setting the external connection to 720p (1280×720).  1080p is too much bandwidth for the cable lengths to the furthest monitors and they may blink or freeze when set to that mode.  When using Mavericks, inside the Display Preferences you must take it off of Best For Display, set it to Scaled, and pick either 720p or 1280×720 from the list.[/important]

[notice]Please note that the monitor on the podium can also be switched just like the student monitors, and is not dedicated to the podium computer as it used to be.  This is so that the instructor can see exactly what the students are seeing, if desired.  To switch only the podium monitor over to a particular source, press (PROCEDURE NEEDED HERE).[/notice]

Table Cabling and Student Monitor Use

The cables at each table provide 5 network lines for hard-wired connections to student laptops.  There is an additional DVI cable and audio connection for connecting a student laptop to the monitor at that table, with a mini display port adapter provided for convenience (the adapter can be removed but is tethered to the DVI cable).  To use this connection, simply connect the cable to your laptop.  The monitor will auto-switch to that connection; do not change inputs on the monitor.  In other words, the laptop connection automatically overrides what the instructor is sending.  To see what the instructor is sending to your table monitor, disconnect the cable from your laptop.

[important]Again, 720p (1280×720) yields the best results for a laptop connection.  You may run mirrored displays or separate.[/important]

[notice]Please note that it is not possible to send a table laptop signal to all the monitors in the room.  Each DVI connection at the tables only overrides that one monitor.  If a student needs to share something from their laptop with all the monitors, they’ll need to connect it at the podium position.[/notice]


Use the receiver in the corner to select sources and adjust volume.  You’ll also need to make sure the podium computer’s or your laptop’s sound is internally turned up.
