Some companies that help connect computers to televisions with wireless adapters are PCMag and Tom's Guide. Both of these websites offer self-help sections, which detail the proper instructions to complete basic tasks such as connecting devices for streaming purposes.
PCMag offers several ways to connect a television and computer, most of which require purchasing a streaming or cloud-based device and installing it on both components. It also highlights using a WiDi, which is a wireless standard feature found on most devices.
Tom's Guide offers similar solutions for connecting both mobile devices and computers to the TV and explains which technology to use for tasks such as streaming or sling videos.
