I want to make an iwb using wii but am not sure what kind of projector i need for my ESL class in Greece. Does it matter if the "analysis" is 800 * 600 or 1024 * 768? The second ones seem a bit expensive for our budget.
The whiteboard our classroom has is about 150cm * 100cm
Thanks

Hi,

If the price is an issue, the 800*600 is sufficient for most general lessons and presentations.

However, at the native resolution of 800*600 of the projector, you will notice that you little space for interacting with the computer as everything appears bigger. For example, the MS Office 2007 toolbar will use a significant portion of the screen. The projector should be able to handle higher resolution input such as 1024*768 but the effect on the screen will be lost of sharpness as the input is down sampled from 1024*768 to 800*600.

The whiteboard in your classroom is not too huge, so it should be alright to use the 800x600 projector with the above limitations.

Thanks for the help Jin
One more question
Do you think it is worth buying an LCD screen instead of a projector? We plan on buying a "normal" whiteboard at some point in the future anyway.

Hi,

If you are using in a classroom, a projector is certainly more practical. Also, although it is possible to turn the LCD screen into an interactive whiteboard, there might be risk of the screen getting scratched.

Just recently bought a 1.2 x 2.4m piece of Perspex for $40.

This is sufficient to cover and protect pretty much any screen.

The tip I got was ask sign writers where they get their Perspex from, and roll up with the right $ in cash.
