If your room contains wall to wall windows or extremely bright lights, LCD's will perform better. Still, in the perfect setting, side by side, Plasma TVs will give you an even better picture. Therefore, if you have the ability to dim the lights and if your window treatments adequately block the sunlight from the TV, you will be happy to find that a Plasma will give you the best picture possible.
Your seating area also plays a large role in this decision. Plasmas have a perfect viewing angle. No matter where you sit, the picture will remain intact. Some, although not all, LCDs have poor viewing angles. In an average set up, the LCD will perform fine. Still, if you are planning on watching content with fast motion such as action movies or sports, be sure to purchase either a Plasma or a high speed LCD, 120Hz.
Similarities between these TVs are the flat panel option and the estimated lifespan. The manufacturer specification’s states that both LCDs and Plasmas will last 60,000 hours which averages 44 years. Both options will give you superb picture when chosen specifically for your entertainment room. If you are buying an LCD television, you must determine the distance between the average seating area and the TV. This distance should be at least three times size of your TV. For example, if you have a 46” LCD, your seating area should be 138 inches or about 11-1/2 feet from the TV. The reason for this is pixelation. In this room with your 46” LCD, if you were to sit any closer than 11-1/2 feet you would not see the best picture quality. Regarding Plasma TVs , you can sit as close to the TV as you like without noticing any pixelation. This choice really comes down to preference. On average, you could sit comfortably about 7 feet from a 42 inch Plasma and 9 feet from a 50 inch plasma.
