.computer whiteboard.Many teachers who used the whiteboard in the first place encountered problems when operating the electronic whiteboard. They always complained that the quality of the electronic whiteboard hardware was not good, and the electronic whiteboard was not sensitive. Some teachers will always say after listening to my training and on-site demonstrations: "Why can't our own school's electronic whiteboard be as good as your electronic whiteboard?" When I helped the teachers solve similar problems, I found that most of them were not whiteboard hardware problems, not even whiteboard software problems. Their main problems are: 1. The screen resolution setting is incorrect, causing the whiteboard display to be too small or super-screen, and the whiteboard pen cannot operate normally. 2, there is no positioning or positioning is not allowed in advance, so that the whiteboard pen can not point to that, it seems that the electronic whiteboard is out of order. 3, the electronic whiteboard software is not completely installed, generally in the installation of the electronic whiteboard software to exit 360 and other anti-virus software to ensure that the software installation of the electronic whiteboard is complete. 4. The whiteboard software is only activated when the USB cable is not inserted into the whiteboard or the whiteboard driver is not activated.
