Digital projectors can now produce very high quality images, so you can have your own high quality home cinema, and prices are dropping all the time, making them a good alternative to LCD TVs or plasma TVs for a superb home viewing experience. Modern projectors over pixel perfect sharpness and vibrant colours and projector technology continues to advance very quickly.
Projector screens are relatively cheap and a 100" screen can give a cinema-like experience.
Projectors need the room lights to be turned off to provide a good viewing experience. In daytime light conditions, a TV will provide a better viewing experience.
Projectors can also be great for watching HD TV.
One disadvantage with projectors is that unless you can afford to have a dedicated projector room, then turning on the projector is less convenient than turning on the TV, e.g. you might have to pull down the projector screen each time.

Reasons to Buy a Projector
A projector can provide an immersive viewing experience, unlike a TV. There is nothing like a large wall sized display for home movie viewing.
Investing in a projector will give you years of home entertainment pleasure. Whilst a home projector set-up is not cheap, if you want to watch a lot of films then over time it will work out cheaper than going to the cinema.
Are There Any Disadvantages to Using a Projector in a Home Cinema Experience?
You need to have the room available at home to allow a good projector set-up, i.e. more space is required than a TV.
Projectors require darkness to get a good viewing experience. You may need to spend money on blackout blinds to darken the room enough during the daytime.
If you want to watch TV on and off throughout the day, a projector isn't the ideal solution. That's because a projector set-up usually takes a bit more time to switch on and be ready for viewing than a TV, and it is bad for a projector bulb to keep switching it on and off. You are better off having a normal TV for on/off TV viewing, and using a projector just for more prolonged viewing, e.g. watching a DVD.
For DLP/LCD projectors, the projector bulb typically lasts 1,000 to 4,000 hours and will eventually need replacement. However, many people will want to upgrade to a new projector before projector bulb replacement is necessary.
Looking After Your Projector Bulb
Projector bulbs, also referred to as projector lamps, will fail eventually and will need replacing. As they aren't cheap, it makes sense to look after your projector bulb as best you can. This means:
- Allow your projector to power down correctly, i.e. to go through it's full power down routine and go into standby. This will give the fans time to cool down the bulb. If you were to instantly cut power to the projector, the bulb glass gets damaged by high temperatures.
- As a power cut would immediately cut power to your projector, consider buying a battery UPS so that the projector can power down correctly in the event of a power cut.
- Once you have switched off the projector, don't switch it on again for at least half an hour. Switching it back on earlier than this is bad for the projector bulb.
- You will know when your projector lamp is on the way out as lighting performance will fall away and the lamp may start to flicker when you switch the projector on.
- Clean the air filters of the projector so that they can continue to do their job and the projector does not over heat. Check the manual for how often this needs to be done, or do it at least monthly.
