This mode decreases the lamp brightness and power consumption in order to extend the lamp lifetime and reduce noise and power consumption. <Bright> : This mode maximizes the lamp brightness when the ambient illumination is bright. As the brightness of the lamp increases, the lamp lifetime may be reduced and the noise and power consumption may increase. · Auto Keystone If video scenes are distorted or tilted, you can compensate for this by setting the <Auto Keystone> function to <On> so that the <V-Keystone> function automatically starts. · <Off>-<On> V-Keystone If video scenes are distorted or tilted, you can compensate for this using the vertical Keystone function. · · The sound output of your projector is temporarily stopped while the keystone is being changed.

[. . . ] Like other video display devices, the LCD panel may contain bad pixels which do not operate. When shipping a product, the conditions for identifying bad pixels and the number of bad pixels that a LCD panel is allowed to contain are strictly managed in accordance with the relevant specified standards by the LCD panel manufacturer and our company. Though a screen may have some dead pixels, this does not affect the overall screen quality and the lifetime of the product.
