Maighstir: My cheap-ass 20" and 17" TN monitors from ten years ago have them, even some of my CRT displays have had settings for contrast and brightness, I would be quite surprised if yours do not - unless you use a cheap TV instead of an actual computer display.
JDelekto: Haha, they may have them then. They were like $99 displays on the cheap, so I got a pair. I was actually hoping to use them as a cheap TV someday. :)
Seeing how TVs nowadays are often just used as displays with built-in speakers (if even that) rather than actually using its broadcast receiver function that gave them the name "tele-vision", because a digital television receiver or cable/satellite box is what actually receives the signal, passes the image and audio of the chosen channel to the monitor/speakers (TV) (maybe there's even a unit in between the broadcast receiver and display that separates the audio and image to send the audio to external speakers), your monitors may very well work perfectly fine for "TV" use, depending on the rest of your media setup.
I don't have a television, but since I have a projector, HDMI receiver and a speaker set, I could easily hook up a DVB-T receiver to one of the inputs on the HDMI receiver and thus view television broadcasts.
