Microsoft is such a powerful tool for presentation, but sometimes we are limited by its requirement; you must have a computer with PowerPoint installed. Sometimes we want to send our presentation like photo presentation to friends or families and share with them, but on different operating system or different PowerPoint version , it doesn't work very well, that's really a disappoint thing. All things seem to be under Microsoft's dominion; is there anything we can do? Why not watch your PowerPoint on TV? Sounds great! I believe many people have already done this interesting and useful thing, and I'm so glad to share experience with you about how to view PowerPoint on TV.
Free way
The free way is connect your TV to computer, then use computer control PowerPoint presentation, there is a vast difference between the technologies of a computer monitor and a TV monitor, you can connect your PC to TV, and watch your PowerPoint on TV screen, but this job is not that easy!
Unlike computer monitors TV monitors are interlaced which has the effect of making thin lines and text shimmer. TV monitors generally (apart from broadcast spec) don't show the full image, so you may lose stuff at the edge of the screen (thus further reducing the amount of available resolution). Some graphics cards do compensate for this by squeezing the image into a window inside the video output - the only way you'll know is to test it.
This method depends on the output from your video card...if you have component video out, you can use that kind of cable, if you have a s-video out from the card and s-video input on your TV you can use that, otherwise you would need a convert from Radio Shack to connect to the TV. As I know, some laptops come with an S-video port, and if your TV or VCR has an S-video input then just use an S-video cable. Otherwise you'll need a cheap scalar/converter to take the VGA signal and turn it into a signal the TV/VCR can accept, most likely over a composite (RCA) or RF (like what your TV cable comes in on). In my opinion, this way cost a lot of time, and the result is not as we expect!
