Is projector better than TV
Many who want to buy big TVs have this doubt ‘which is best Projector or TV?’ A big TV compared to a projector has many advantages like ease of use, and others. Buying a TV is an easy decision because you are doing what everybody else does and not venturing out of the ordinary. But the lure of a giant picture from a projector, at almost the same price or even cheaper than the big a TV, does make some to take the bold decision to buy a projector, and most of them will never regret that decision. The drawing here compares the size of a 42 inch TV with that of 100 plus inch screens and a 6 foot man. If the picture on these big projector screens are clear and bright, then there should be no doubt that a projector is a better buy than any big TV.
With a projector in the house, you literally have the same type picture on a screen like in a Movie Theater. Watching a movie in your own house, on a 100-inch or more screen with full surround sound is an exhilarating experience and is as good or better than seeing a movie in a theater. The sketch above should give you an idea of how a projector screen size compares with a TV. With a bright projector picture, not even the biggest TV can come close to the enjoyment of watching a movie on a projector screen.

|Installation||Installing TVs bigger than 65 inches is proffessional job and requires the help of installation technicians. Big TVs are heavy, and one person alone cannot manage it.||Projectors are easy to install. The projector itself is very light and small and can be easily hidden away in a cupboard. One person can easily install it.|
|Convenience||Once installed a TV cannot be moved about from room to room.||Projectors are small and light, and it can be moved about from room to room or outdoors or even taken to a friends house. A screen is not essential for a projector, A projector picture can be seen on a wall, and the picture will be good if the wall is smooth and without any fixtures.|
|Connections||Making connections to a wall mounted TV is difficult.||Making connections on a projector is easy and straightforward. Anything that can be connected to a TV can also be connected to a projector.|
|Brightness||A TV has a very bright picture and can be seen with the room curtains opened or with lights on in the room.||Projector pictures are not that bright and hence to see a good projector picture it is better to have the curtains closed, and the lights switched off.|
|Eye Strain||A TV picture tends to cause more eye strain. This is because the TV picture occupies only a small fraction of the angle of vision of the human eyes when sitting about 8 to 10 feet from the TV. So your eyes find it difficult and struggle to cope with a bright object in a small fraction of your total vision.||Watching Projector images are less of a strain on the eyes, first of all, because the picture on the projector screen is not overly bright. Secondly, because of the massive size of the projector picture, it fills a significant fraction of the total angle of vision of the human eye and hence causes less eye strain.|

Setting up a projector home theater at home
First of all to use a projector, it is not necessary to have totally dark rooms. With a projector of over 1000 Lumens, a 100 inch projector picture will look good in a room with curtains drawn. The thing to understand is that with just a 400 Lumen bright projector you can get a bright 100 inch picture if the room is fully dark. If you have projectors in the 2000 Lumen range, the pictures are bright and can be seen even in rooms without the curtains being drawn during daytime.
Setting up a projector at home is very easy. The following videos from leading projector manufacturers Epson and Sony, should give you some idea of how easy it is to set up and watch movies and TV shows on a projector at home.
The first 2 videos show the Epson projector model 2030 which is an old model. In August 2015 Epson released their newer model 2040. These are the prices of the new model projector Epson 2040:
Projector Screen size compared to TV 65 inch
Let us consider the ratio of the screen area of a 65 inch TV image to a 100 inch Projector image. The Width of a 65 inch screen is 56.65 inches and the Height 31.87 inches to give an area of 1805.34 inches². A 100 inch Projector image has a width of 87.16 inches and a height of 49.03 inches to give an Area of 4273.00 inches². Even though the difference of the diagonal size is only about 1.5 (100/65 = 1.54) the difference in the area of the two images is 2.37 (4273/1805 = 2.37). Thus you get a projector image almost 2 ½ times the size of a big 65 inch TV. TVs bigger than 65 inches are very expensive, much more than a high quality Projector.
The quality of a 100 inch picture produced by a good quality projector is superb and if seen side by side with the best quality TV image on a 65 inch or even larger TV, you will definitely opt for a projector. The downside of the projector is that you should watch a projector in a room that is not bright. As long as the room is dark, the projector image will have a much better quality, like better contrast ratio, more clarity in the larger picture and feeling you are seeing a real cinema in a theatre. The Projector image is easier on the eyes and causes less eye strain compared to the bright picture in a TV screen.
To summarize here are:
Advantages of Projector over TV
The main advantage of a projector over TV is that you get a much larger picture for about the same price as a big TV. If you consider the cost per inch of TV size, a projector works out much cheaper. One other good advantage of a projector over a big TV is the size of the projector. A projector weighs less than 20lbs (9Kg) and is very easily portable, can be quickly dismantled and set up in a new location with no problem. A large TV on the other hand is heavy and fragile and you have to be very careful when moving a large TV. You will need specialist installers of TVs to remove and set up a large TV in a new location.
Disadvantages of projector over TV
The biggest disadvantage of a projector over a TV is that you will require a darkened room to see good pictures. It is possible to have very bright projectors which can be shown in regular room lighting, but such projectors are more for business use. Home projectors are meant to be shown in rooms with blinds, shades or curtains drawn and room lighting switched off. In a darkened room, no TV picture can compare with the quality of the large picture of a projector.
Another major disadvantage of the projector is life of the projector lamp, which is about 3000 hours for the shortest life and cheapest Metal Halide Projector Lamps. So if you are watching the projector with Metal Halide Projector Lamps for 4 hours daily on an average, every day of the year, then you will be using the projector for 365x4=1460 hours and you will require to change this lamp once every 2 years. The cost of Metal Halide Projector Lamps is under $100 for the 3000 hours projector lamps. High efficiency HID Projector lamps with service life up to 10,000 hours are now available, though they are more expensive.
The latest projectors are now available with LED and Laser light sources. The LED projector lamps are claimed to last over 20,000 hours but are not as bright as the Metal Halide projector Lamps. Projectors with Laser lamps are also long lasting and very bright projectors, but right now they are priced very high. Expect laser projector prices to drop soon as more and more manufacturers get into this field. Other problems with Projectors with Metal Halide Lamps are:
- The heat produced by the Projector’s Metal Halide Lamp requires a high speed fan to keep the Metal Halide Lamp cool and the fan noise may be disturbing for some.
- The Metal Halide projector Lamp requires a few seconds, up to 20 seconds, to start up and so not a an instant on like a TV.
- When shutting down a projector, the lamp needs to be cooled, and so the projector fan keeps running for about a minute after it is switched off
- Projector Metal Halide Lamps requires about 200 watts of power to run.
