Also – is likely to be possible to have a way to have a Web App on the screen at the same as a PPT? In a lecture theatre in level two and other places?
If I have two screens – such as in Leicester street level one, can I split the projection there? If this possible – how do I do it?
ROOM CONFIG
1.) From the AMX controller select computer (I used room L1.06 for my testing, the other teaching spaces fitted with an IWB should provide a similar option.)
2.) Send the Laptop signal to the projector, send the Mac signal to the SmartBoard. This gives a different input for each projector. (These signals can be reversed depending on which option best suits the requirements)
TWO SCREENS, TWO IMAGES?
i.) The easiest way to have a PPT and the Web App is to have the PowerPoint running on the laptop (iPad?) and the Web App running from the Mac mini. It does mean that you are controlling two separate computers during the lecture – but there are no extra costs.
I WANT ALL THIS; FROM A LAPTOP!
ii.) You can use a USB Video card to give a second output from a single computer. These are relatively cheap, but can produce a poor image. You would need to test how PowerPoint behaves in this environment, it will most likely show the presentation on the primary graphic output and not the USB output.
eg. USB to Video Adaptor (Jaycar USB to DVI Adaptor, CAT. NO. XC4879, $69.95)
- The Jaycar USB to DVI Adaptor plugged straight into the PC laptop and was running in a few seconds (Compaq 6710b,Win XP). Setting the onboard graphics card to mirror to the laptop and external display gave the PPT output to ‘screen 1′. The web app was set to run on the USB and ‘gave screen 2′.
- The Jaycar USB to DVI Adaptor was not recognised by the MacBook (MacBook Pro, OSX.6.8), either directly connected or via a powered hub. (May need to trial the IOGEAR USB 2.0 External DVI/VGA Video Card for the Mac).
Using a USB 2.0 UGA Multi-Display Adapter with the DisplayLink driver we have a working Triple headed MacBook Pro, with PPT presentation.
iii.) You can use an external Graphics Expansion module, these make the computer think that it has a much larger single screen and then divide the output across multiple screens. You would need to test how PowerPoint behaves in this environment as it may try to expand across the entire expansion to ‘fill the screen’.
eg. MaTrox eXpansion ($250-$500 depending on options)
These are probably not portable enough for the case in question, but are another area for investigation.
