- 1). Determine the size of the TV that you'd like, based on your needs. A larger TV, at least 26 inches, functions better in a living room; a smaller TV, 20 inches or smaller, works better in a bedroom. Analog TVs in America have 525 lines of resolution, regardless of the size of the screen.
- 2). Decide whether you'd prefer interlacing or progressive scan for sharpness. With interlacing, the TV fills in half of the resolution first, then fills in the second half for each frame. With progressive, each frame is filled in with one pass. For a sharper picture, progressive scan is preferable.
- 3). Figure out the sound capabilities you want. Basic TVs produce only stereo sound (left and right channels), while newer sets have a surround-sound options.
- 4). Determine the number and style of outputs and inputs you'd like. All TVs have a coaxial input, many have component inputs (red, white and yellow) and a few feature s-video inputs. The s-video input offers the best quality picture and coaxial the worst, but some appliances don't support all three.
- 5). Figure out your budget and the features you would like. Adding size, progressive scan and types of inputs to the TV add to the price of your television.
- 6). Search your local markets for used, quality TVs that match your needs. The number of TVs available have driven CRTs to bargain prices. Websites usually feature many people giving away their TVs for free or selling them for little money.
