It is possible to use an Olevia TV as monitor for a computer provided that it has the proper connections. The simplest way to connect a TV to a computer is via an HMDI cable. Most modern personal computers have this type of output, and all high-definition televisions do.
In the event that a computer does not have an HDMI output, nearly all computers have an SVGA output, the standard connection between a computer and a monitor. Many modern TVs have this type of connection as well. The only drawback to using an SVGA connection rather than an HDMI connection is that SVGA does not transfer sound, so a separate connection is necessary for the TV to play audio from the computer.
