A Good Rule Of Thumb Would Be To Check For Compatibility Of The Computer Resolution With That Of The Projector Resolution. Although, The Scaling Technology Of Projectors Allow For The Accommodation Of Different Resolutions, The Resulting Image Quality Would Be Compromised. Thus, It Would Be A Good Rule To Follow To Match Both Resolutions. The Most Common Resolution Is XGA (1024 X 768).The Brightness Of These Projectors, Which Is Measured In ANSI Lumens, Determines Its Power To Project Text And Images With Good Quality. With Around 1,000 ANSI Lumens, These New Projectors May Be Used For Projecting Black And White Images In Dark Rooms. But If Multi-colored Presentations Will Be Made With That Lumens Rating, One Would See Washed-out Colors. This Is Even Worsened With The Presence Of Ambient Light. It Is Thus Recommended That At Least 1,200 Be The Value Of Your Projectors Brightness. For Meeting Rooms, The Range Would Be Around 1,000 To 2,500 ANSI Lumens Depending On The Degree Of Ambient Light Present. For Training And Conference Rooms, The Range Would Be Around 2,500 To 5,000 ANSI Lumens. Larger Audiences Would Require That The Images Projected Be Large Enough. This Would Require A Higher Lumen Output. Brightness Uniformity Should Also Be Considered. This Is The Distribution Of Brightness From Edge To Edge, Corner To Corner. The Higher The Uniformity Rating, The Better The Consistency Of The Image Brightness Throughout The Span Of The Projection.Check Also For The Lamp Specification Of These New Projectors. Choose The Lamp With The Lower Wattage But Producing The Same Brightness. This Lower Wattage Will Keep Your Lamp At Lower Temperatures Than Those With Higher Wattage. Costs For Lamp Replacement Varies From 250 Dollars To Around 600 Dollars. Lamp Life Would Be On The 1,000 To 5,000 Hours Range. It Would Be Better If The Projectors Come With An Economy Mode Feature. With This Feature, Around 20 Of The Brightness Is Taken Out. The Advantages Though Are Reduced Electricity Usage, Less Noise And Longer Lamp Life.Also It Is Worth It To Check For Other Available Features That Come With The New Projectors. These Would Include Its Portability, Networkability, Availability Of Component Video Inputs, Wireless Mouse Control.One Should Not Buy New Projectors In Haste, Rather, More Care Planning Should Be Done. Know What You Need And List Them. After Which, You May Start To Check For Models Of New Projectors That Meet Your Requirements. Choose The Brand, Which You Feel, Can Give You Excellent Customer Service And Effective Technical Support.
