Many of us give presentations to an audience using LCD/ DLP projectors. But we are not aware of certain projector features that can be used to give more effective presentations. In this post, let us look at some projector features that could be used while making a presentation using LCD/ DLP projector.
1. Wireless Mouse/ Full-function Remote: Many projectors come with full function remote controls (or) one can buy a wireless presenter to enable remote mouse controls from the dais / stage, even though they are at a considerable distance from the PC/ Laptop connected to the projector. Stop saying ‘Next slide please’ to someone in the audience and go to the next slide by the press of a button on the wireless mouse/ full function remote in your hands. These devices come with built-in Laser pointers that could be useful while making presentations.
2. Focus/ Optical Zoom/ Digital Zoom: While the focus/ optical zoom can be adjusted from the rotating handles on top of the lens, the presenter should use them to set the projector to the sharpest focus/ best screen size. Of course, one cannot use these functions if the projector is ceiling mounted.
The digital zoom could be a useful function in situations where the presenter needs to focus on a particular area on the screen, but that portion is not visible to everyone clearly. The sharpness of the image/ characters may go down while using the digital zoom, but their size will increase which enables users to see a specific area clearly.
3. Blank/ Shutter: If a projector image is projected on a white board and the presenter wants to write something on the white board, they can use the Blank/ Shutter function that electronically shuts off the projector lamp. This could be revoked and the projector can start displaying images back immediately, with the press of a button. The problem with shutting down a projector manually (to achieve the same thing) is the longer time taken for the projector/ lamp to re-start.
4. Freeze: Many a time, we see people connecting the projector to the laptop and accessing their presentation files from an internal directory. But doing this exposes many other files while navigating to a particular directory. So, one can use the freeze function to display a particular screen on the projector (the start up – desktop screen, for instance) while they access their file from internal directories. The freeze function can be released once the presentation is displayed on the full laptop screen.
5. Keystone: When a projector is not ceiling mounted (and is mounted on a table), its front legs needs to be lifted a bit for the image to fit on the screen properly. This creates a trapezoidal image instead of the rectangle image. The user can use the keystone correction function built into the projector (+ and – keys) to adjust the screen layout and make the projector display a rectangular image, instead of the trapezoid.
6. Audio: Many a time, one needs to show multimedia content/ video while making a presentation. This type of content is always displayed along with audio. So, if the facility does not have any external speakers that can be attached to the projector/ laptop, one can always connect audio cables directly from the PC/ Laptop to the projector and use the in-built speakers of the projectors. Some projectors come with speakers that are more powerful than the standard laptop speakers.
