Why can’t I calibrate my interactive board? When trying to calibrate, the first two “X’s” calibrate fine, but the next few “X’s” have disappeared.

Be sure your computer is set to mirror displays and that the resolution is set to 1024 x 768 on both the computer and projector (see KB Article 312). The projector's refresh rate should be set to 60GHz.

You may also need to reposition the projector's image. Use the projector's remote control and go to the signal tab by navigating menu/signal/position .

If this doesn't solve the problem, create a Web Help Desk work order ticket.
