NEC projectors are made for classrooms, meeting rooms and halls, the kind of place where a unit gets installed on a bracket and then left alone. Resolution and brightness are how to narrow them down. XGA units such as the NP-CK4155XG handle standard 4:3 material, WXGA units such as the NP-UM351WG suit widescreen content, and the WUXGA NP-P525ULG runs a laser light source at 5000 lumens. The UM models mount close to the screen.
