iv. Scan Frequencies:

Minimum Horizontal Frequency Range = 15 kHz to 79 kHz
Minimum Vertical Frequency Range = 24 Hz to 100 Hz

C. Performance Specifications:

i. Brightness:

With a new lamp the projector shall deliver a minimum of 3500 Lumens measured
according to the ANSI/NAPM IT7.228-1997 specification.

ii. Lamp Life and Lumen Maintenance:

The projection lamp shall have a minimum lamp life of 750 hours of operation, with
light output no less than 50% of the rated light output at the specified lamp life.

Example: A lamp rated at 3500 ANSI Lumens and a lamp life of 750 hours shall
deliver no less than 1750 ANSI Lumens at 750 hours of operation.

iii. Brightness Uniformity:

The projector shall deliver a minimum of 90% brightness uniformity throughout the
specified life of the lamp. The brightness uniformity shall be measured according to
the ANSI/NAPM IT7.228-1997 specification.

iv. Color and Gray-scale:

- Gray-scale Uniformity:
The projector shall deliver a minimum of 95% gray-scale uniformity across the
entire projected image, and throughout the specified life of the lamp. The gray­scale uniformity shall be measured using the 9 zones specified in the
ANSI/NAPM IT7.228-1997 specification.

- Color Temperature:
The projector shall deliver a color temperature range of 2000K - 9300 K
adjustable from the remote control.

- Color Gamut:
The projector shall be capable of producing over 1 billion shades of color.

- Stability:
The projector shall maintain color stability and gray-scale uniformity throughout
the life of the projector and all of its components, including the lamp, without
manipulation of the projector controls. The projector color temperature shall

deviate no more than ±200K throughout the rated life of the lamp.

v. Contrast Ratio:

The projector shall deliver a minimum contrast ratio of 150:1 measured according to
the ANSI/NAPM IT7.228-1997 specification.
