C40 - HDMI 2 Input use

I have a C40 with dual display connected to two 80" sharp TV's and a Smartboard projector.  Design concept is video (far-end) to TV 1, and content delivered to TV 2 and SmartBoard with the source either being an instructors laptop or a document camera.  If I connect the laptop HDMI out to the C40 HDMI 2 input, and I also connect a document camera DVI out to the C40 DVI in, is there a way to select the source to display as the content?

Yes, you can either select

Yes, you can either select the presentation source you want from the menu, or by pressing and holding down the presentation key, which will give you the same options as you get when going via the menu. See attached screenshots. This is assuming you have configured the sources, see "source.gif".

Thnx for the reply Jens.

Thnx for the reply Jens. Forgot that Ihad a 2nd camera in the design that is using the HDMI port.

Here is the design i am trying to make work if anyone has any recommendations:

Laptop VGA and Doc Camera VGA => Cisco C40 DVI In => Cisco C40 DVI out => DVI to HDMI cable => HDMI splitter X2 => Sharp 80" TV ans Smartboard Epson projector.  Can we put a VGA switch between the codec and the laptop/doc camera and still have full screen resolution at the 80" TV?

Yes you can certainly do that, but why not run the PC through the document camera instead? Depending on the document camera you have, you might be able to use either DVI or HDMI out from it to DVI in on the C40.

We did that for a while in some of our rooms, and it worked really well, however, to accommodate all devices, and to avoid having to use dongles etc for Macs, we are now using Extron DVS605 instead - see http://www.extron.com/company/article.aspx?id=dvs605ad and that has been a raging success. :) It allows us to have separate cables for VGA, HDMI and Mini-Displayport, and in your case, you would use HDMI out from the DVS to DVI in on the C40.

When they run the laptop

When they run the laptop signal thru the document camera the picture at the 80" Sharp is lower resolution and does not fill the entire screen.  If the laptop is connect direct to the C40 the pix is OK, and the document camera signal is also OK.  The only issue we are having is with the laptop signal when it goes thru the document camera.  Their document camera is a Smart Document Camera  Model SDC-330 with a VGA-DVI-D/composite selectable mechanical switch, and the outputs are; (1) DVI-D, and (1) VGA.

Maybe the solution for this is a new document camera?

 

Yikes, yes a newer document

Yikes, yes a newer document camera would absolutely not be a bad idea. :)

We use a lot of Elmo and Lumens document cameras, both with HDMI out, i.e. Elmo P30HD and Lumens PS751.
