Use a regular analog tube TV as a monitor

Q: How do I use a regular analog TV as a monitor for my computer? Is there a card that can be inserted into my computer to convert it?

A: If you mean a normal “Tube” TV then the answer is that it is possible but the picture is going to look terrible.  A normal tube TV has a very low resolution. The pixels, or individual dots, on the screen are huge compared to a computer monitor, so you are going to have a terrible time trying to read anything on the screen.

I’ve tried it before and it’s completely unusable. It can work for something like a simple PowerPoint or video playback but you will still need a separate computer monitor hooked up just so you can read what’s on the screen. You would be much better off taking someone’s old CRT monitor off craigslist for $5 and using that.

If you want to give it a shot and see what happens then what you will want to do is figure out what connections you have on your computer and what connections you have on your TV. Chances are you have VGA out on your computer and you probably have S-Video, Composite, or Component on your TV. This means you would need to get a VGA to S-Video, VGA to Composite, or VGA to Component.
