Is it important to have masking on my screen?
Yes, it is important. Black Masking borders help absorb light overshoot from your projector and provide a professionally matted presentation. It also helps increase the picture focus point.
What is the advantage of black backing on the screen material?
Black Backing is an important feature that prevents light penetration and increases reflectivity for sharper color reproduction.
What screen material should I get?
Screen material selection will depend on various factors such as type of application, environment, and projector. Please see the screen material selection guide for a better understanding of the materials we offer.
Should I use a standard top masking or an extra drop masking border?
It depends on how high you want to hang the screen. If you are planning on a high ceiling or in-ceiling installation, use a product with an extra black masking border like E24 (24" drop) or E30 (30" drop) model. Aside from that, our general product lines will accommodate your typical home or commercial presentation room ceiling heights. All of our manual and electric screens are suitable for wall or ceiling installations All of our electric wall/ceiling screens have adjustable vertical limit switches to help you achieve the perfect drop setting.
Are Elite Screens High Gain screen materials angular or retro reflective?
Elite Screens StarBright™ 4 and StarBright™ 7 Ultra High Gain screen materials are angular reflective.

How to Extend Projector Lamp life
How to Extend Projector Lamp Life?
Today’s projector lamps last an average of 2,000-3,000 hours. With a typical replacement lamp running around $300 shouldn’t we do everything we can to ensure maximum lamp life? Projectors operated under these basic operating principles will have the greatest chance of lasting through the entire rated lamp life.
1. Test your lamp:
When you get a new projector make sure to run the unit for at least 20 hrs. during the first 1-2 weeks. If the lamp is defective, it will usually fail within the first 10-20 hours of operation. With lamp warranties lasting an average of 90 days it is best to discover any issues sooner rather than later.
2. Clean your vents and air filters:
If your projector has an air filter, make sure to keep it clean. The dust filter should be cleaned every 3-6 months. Clogged filters or vents will not allow the proper ventilation of heat and can cause the projector lamp to overheat or even fail.
3. Allow proper ventilation:
Do not obstruct the intake or exhaust vents on your projector. If your vents do not have room for adequate ventilation you risk the chance of overheating your projector.
4. Choose proper operating environment:
Avoid environments with extreme humidity, temperature, and dust.
5. Allow the lamp to cool before unplugging:
Do not unplug the projector until the lamp has finished cooling. After the projector has been shut off, fans will continue to run to ensure even cooling which will decrease the chance of early lamp failure.
6. Do not move until cool:
Hot lamps are very fragile, never move a projector until the lamp has completely cooled. Shock and vibration may damage sensitive lamp filaments.
7. Minimize on/off cycles:
Do not frequently turn the projector on and off. Each time the projector is turned on, the rush of power causes stress on the lamp filaments.
8. Wait one hour after cooling to turn on again:
After prolonged use (3+ hours) and shutdown, wait at least one hour to turn the projector on again. If a lamp is still warm/hot, the projector will send to much voltage early in the lamp heat-up cycle which will drastically decrease lamp life.
9. Do not handle the lamp without gloves:
Oils and deposits from hands and fingers can cause “hot spots” which results in temperature gradient stresses which result in early lamp failure.
10. Operate in “Economy” or “Low-lamp” mode:
Whenever possible use the “low-lamp” or “economy mode” on your projector. Economy mode is known to increase lamp life up to %50 with only a 20% reduction in brightness.
11. Never leave your projector in the car on a hot or cold day:
If a projector was left outside in a car for example make sure to allow the projector to adjust to room temperature before turning it on. If the lamp is 35 degrees or below it may explode if turned on immediately once brought inside. Further, projectors left in the hot sun have a tendency to overheat if not allowed to cool down before operation.
12. Test replacement/spare lamps:
If you purchase an extra lamp before it is time to replace your existing lamp is recommended to remove the existing lamp and use the old lamp as a spare. If a lamp is defective it will typically fail within the first 10-20 hours, using the new lamp early ensures you do not have a defective lamp and allows adequate time for replacement if you find the lamp to be faulty.
