InFocus X10 Projector: Black Level Performance
Black levels are the InFocus X10's weakness. Keep in mind, this is InFocus's entry level 1080p projector, and it is using TI's Darkchip 1, which, today, is their entry level performance 1080 resolution DLP processor. Black levels are strictly entry level, and no match for example, to the Epson Home Cinema 1080 UB, which has the best overall black level performance of any of the under $3000 home theater projectors. It doesn't stop there, however. Others with a black level advantage include the entry level Optoma's (mostly by virtue of having a dynamic iris). The HD803, also for example, starts with the Darkchip1. Most of the 3LCD projectors near its price (on either side), can do better than the X10, especially on very dark scenes.
For comparison purposes, here's the classic starship image from The Fifth Element. The first one is the X10. Direcly below it, is the same frame from the Epson Home Cinema 1080 UB, followed by the recently reviewed Mitsubishi HC5500, and the BenQ W5000 (which also uses the Darkchip1).
