When you can't see the whole PC screen on the WB

Sometimes, the bottom edge of the PC screen (where the taskbar lives) does not show in full on the WB.

What can you do?

You could, as a temporary work-round, use the Alt and Tab keys to step through all open windows, and then choose the one you want to work with by letting go of the Alt key.

Otherwise, try pressing the aspect key on the projector remote control - that's probably how the screen got that way in the first place. Again, step through all the options until you find the one you want.

It is also possible that the screen resolution has been altered - change it back to 1024 x 768 and see if that helps.

One final comment: the 16:9 aspect gives a smaller screen display on the WB, which may be more suitable for when you don't want the WB to dominate the classroom, or when you are fed up with reaching to the full height of the board.
