Your first option is to utilize a video card with TV-out or video-out device. Although it is best to use a standalone DVD player, you can also watch videos with your computer connected to the TV with a TV-out device. The upside of using this type of device is that you get to play all video formats that you are able to play on your personal computer. This includes formats like DivX, ASF, and MOV. The reason for this is that the TV-out device is simply showing what is on your computer screen.
The downside, however, is that you may not get the best quality. Also, you probably have to endure some noise if you do not have a very long cable and your computer is located near your TV.
Another option is the PC TV tuner. A TV tuner is a device that enables you to connect an analog or digital TV signal to your computer. In a TV set, the tuner is the part that receives signals from over-the-air broadcast or a cable connection, and interprets this signal as moving pictures and sound. The tuner sends this information to the television screen and speakers for viewers to watch. A PC TV tuner works the same way, except for the fact that information is sent to a computer monitor rather than to a television screen.
Lastly, you can choose to use the VGA to PAL/NTSC scan converter, which allows a VGA to pass through so that the signal can be watched both on a PC monitor and on a TV screen. What's good about this converter is that you can play all video formats that you are able to play on your computer. But just like the video-out device, you may not get the best quality both in terms of video and audio.
TV-out or video-out device, PC TV tuner, and VGA to PAL/NTSC scan converter - These are just three options that you can choose from if you want to watch PC on your TV.
