The display of a pocket computer before the class to project, in addition to the calculator an overhead projector, as well as a view screen overhead panel is required. Depending on the available interfaces of the computer model can be connected directly to the computer or need an additional Presentation Link. The VIEW screen can be used for visualization of the functions of the TI-Nspire and TI-Nspire CAS handheld can be used. The TI-Nspire (CAS) Software present by means of laptop/notebook and projector.The TI-Nspire technology is characterized by an enormous variety of function, so that the use of external display almost inevitable, if the lessons with the TI-Nspire CAS optimize the design. Resolution and contrast are so high that even when sunlight is in connection with a bright daylight projector size and sharp images of the display project. The display is suitable for TI-Nspire, TI-Nspire CAS and TI-Nspire + 84 keypad. It is controlled via the USB interface of the handheld. The TI-Nspire VSH VIEW screen works with all hardware and software versions of the TI-Nspire. We recommend the use of the display, if the use of the TI-Nspire PC software for technical reasons, is not possible. The External Display is quickly ready to use, because it without any effort immediately after USB coupling operational. The enough for most cases in the classroom and saves the teacher or the referierenden students a lot of paperwork on the blackboard. Once used on this hardware in the math room no longer do not want to do: Whether it's comparison of results, the design of complex invoices or on graphical analysis - the external display visualizes the results for all pupils, handset, and viewers on fantastic simple way the great range of mathematics. Please note that the simultaneous data collection (with vernier EasyLink) in the current software versions of the handheld is not yet possible.This text is machine translated.
