- The angle at which you watch a rear projection TV will have an impact on the picture quality. If you try to watch a rear projection TV from a side angle, the brightness, color and contrast will look dim. These TVs are best viewed straight on or from a slight angle. The picture also will be distorted if you watch from above or below, such as standing up or lying on the floor.
- Some people have problems with the colors on their rear projection TV. Flashes of light, or "rainbows" sometimes appear. These flashes are usually seen when the viewer's eyes wander away from the screen. Some of the higher-end models now have systems to prevent these "rainbows."
- The lifespan of your rear projection TV will only last as long as the lifespan of the lightsource. These lightsources are bulbs or lamps that need replaced after 5,000 hours to 8,000 hours of use. Lamps in some of the higher-end models tend to last longer than 8,000 hours. The cost for replacement bulbs or lamps is usually at least $200.
- While many people purchase rear projection TV for the large size of its screen, the large size can also have drawbacks. Rear projection TVs are often big and bulky and can take up a significant amount of room. Unlike flat panel TVs, rear projection TVs cannot be mounted to a wall to save space. If you have a room dedicated to entertainment, this might not be a problem, but if the TV is in a multipurpose room, you should take the size of the unit into consideration.
- Keep in mind a few things when shopping around for rear projection TVs. First figure out what room the TV will be in to determine the size. You will not want a TV taking up an inordinate amount of space compared to the size of the room it will be in. If you are concerned about the "rainbow" problem, watch a TV in a retail store to see if you notice it. Take your time, make sure you find the best deals you can, and don't rush into buying the first TV you find.
