The Sharp P621U is a premier Entry Installation Series, LCD, laser projector designed to meet the needs of higher education and corporate users. Sharp's patented IP5x sealed LCD cooling system eliminates the need for a filter and combined with the maintenance free laser light source this projector is as close to set-and-forget as you will find in projection. Another benefit of Sharp's advanced cooling system is whisper quiet operation that eliminates the distraction that can sometimes be caused by a more noisy projector. At 6200 lumens, WUXGA resolution and outstanding LCD color fidelity the P Series delivers impressive looking images in all kinds of demanding applications. Enjoy time-saving installation flexibility with broad horizontal and vertical manual lens shift, a 1.6x manual zoom lens, roll free capability and HDBaseT input.
