A TV screen can be great for viewing the output of other devices. Especially where laptops are concerned, the larger screen improves readability and allows for many viewers to view the computer's output comfortably. PowerPoint presentations, for example, are greatly improved by a larger display. Unfortunately, there is no standardised way for computers to interface with televisions, so this process can be frustrating. The most important factors to keep in mind are the port types on both your computer and your television.

- Cable adaptor (optional)
Connect your laptop to your television while both are off. This will require a cable specific to the port on both devices. The cable will run from your computer's display port to the display input on your television. If these ports are not of the same sort, you will need an adaptor. The most common port/cable types are S-video, RCA, VGA, DVI and HDMI. See the References for help determining your connection types.
Turn on both devices.
Set your television channel to the video channel that corresponds to the input from your laptop. This will often be a channel labelled "Video 1," "Video 2," "Input," etc.
Press the button on your keyboard that corresponds to an external monitor. This is usually labelled "CRT/LCD" and is often a function -- F1 through F12-- button.
Configure the display through your laptop's display settings. If you wish to duplicate your screen, select the "Duplicate" or "Mirror" option. If you wish to use the television as an extension of your desktop, use the desktop extension option. You may also need to configure the aspect ratio and/or resolution of the display if the image appears distorted.
Open the desired PowerPoint file. PowerPoint files have the file extensions .PPS or .PPT. If the PowerPoint presentation is not exactly where you want it on the television screen, drag it or resize it until it suits your needs.
