Geek Speak… Large Monitors/TVs As Monitors

Issue 39.12

With the advent of flat panel televisions and monitors, the line between the two became less defined. Today your computer monitor can often be used as a screen to play TV shows, either by streaming them from websites or by connecting them to your cable or satellite feed. By the same token, many new flat panel televisions have an input or two for your computer, using the VGA (Video Graphics Array -15 pin) cable that has been popular for many years, or, with newer computers that support DVI (Digital Visual Interface) or HDMI (High Definition Multimedia Interface) outputs.

DVI and HDMI boost picture quality to Blu-Ray levels while VGA is comparable to DVD quality. The difference in picture quality and sharpness on a large screen is quite noticeable. With VGA or DVD quality, when your screen gets beyond about 22-24 inches, you notice a slight blurriness to the picture and rapid movement results in streaking and sometimes pixelization (when you see squares of color instead of a smooth rendering of the picture).

By contrast, DVI and HDMI usually give a very clear picture and smooth movement rendering, even when you get into the 50 inch plus range. For this reason, many people have two monitors, one for emailing, homework, typing, spreadsheets, etc. and one for multimedia. The first is usually very sharp in contrast and is specifically a computer monitor in the range of 19 to 24 inches. Larger monitors are available (up to 42 inches) but are quite pricey. Because of that, many people are buying mid-range flat panel televisions as their second, multimedia monitor – usually in the 27-42 inch range.

I personally opted for a 37 inch television as my second and a 22 inch for my main monitor. I don’t even turn on the TV unless I am watching a tv program or movie. The fact that I am sitting less than three feet from the monitor gives me the same visual experience that I would have if I were watching a 60 inch television in my living room but at a much lower cost.

For example, a 32 inch television is available for $200-$300, while a 32 inch monitor will likely cost over $800. The difference in quality of picture is definite, but for most multimedia, the difference is not that noticeable. By contrast, a 60 inch tv to watch in your living room will range from $1000 to $1600.

I am a movie buff so it is worth it to me to have a television as a second monitor, but for most people it may be a luxury you don’t need. In any case, find the tools that will make your computer do what you want it to do – and always make sure you have a back up of anything important.
