Tested projector with new build/Intel Graphics and wireless keyboard.
Turns out that the projector looks fabulous as long as you use its native resolution. The bad news is that its native resolution is 1024x768. Any other 4:3 resolution that works with the Intel Graphics chip looks terrible on the screen.
To get mirroring to work, you need to plug the HDMI plug in to the DVI port on the computer (via the HDMI-DVI converter) and use a VGA cable for the monitor itself. Any other combo is fraught.
Wireless keyboard/trackpad has a nice feel to it but is a real pain to use as it loses its connection regularly. Pressing the connect button MAY work, but it doesn't always. I tried elevating the receiver, which helps some (but not enough). Martin replaced the batteries and reports that performance is better.

If you want to do a presentation in B045 using our equipment:
Projector plugs in to the orange DVI converter and then in to the DVI port on the computer. Monitor plugs in to the computer via the VGA cable.
Connect wireless keyboard: plug the receiver in to the computer using a USB extension cable and elevate the receiver so it's within line-of-sight of the keyboard. Turn on the (keyboard) power and depress the connect button. It should work more-or-less right away.
