Computer teachers in India often find it difficult to show students how to use computers to fifty to sixty students. The teacher handles this problem by showing computer usage for a group at a time or using hand-drawn visual aids. Some schools have overcome this problem by purchasing an LCD Projector, which is useful for sending presentations to a large group. For example, instructors often use LCD projectors to show you how to prepare class books with Microsoft Excel. However, LCD projectors are expensive and replacement of bulbs is very expensive.

The UNVNC viewer works only when the Remote desktop also connects to a remote PC

Hello, here for the first time. I set Ultravnc for two days on a remote computer using the Remote Remote desktop. I installed Ultravnc. I can now connect to the ultravnc server at work, but my viewers are on the black screen. When I connect the remote Windows desktop while the viewer is still active, the viewer comes alive and works as usual. The only problem is that the remote desktop also needs to be opened (the remote computer looks locked on the vnc server). I want viewers (home page) to work without a remote desktop, so people at work can see what I'm doing on the screen. Can someone tell me why viewers work only when the remote desktop is active? Thank you from now
