Connections

There are six video inputs on the rear

panel, including two analog component

video inputs (15-pin D-sub connector and

five BNC jacks) that accept standard and

high-definition YPbPr and RGB video. There

is one composite video input (RCA jack)

and one S-video input (4-pin mini-DIN).

T h e re is also one HDMI digital video input. A

D-4 input, which is primarily used in Japan,

is also included for analog YPbPr signals.

The composite and S-video inputs are

compatible with NTSC, PAL, SECAM,

PAL60, NTSC4.43, PAL-M, and PA L - N

interlaced-video signals. When the analog

RGB inputs are set to RGB-PC mode they

a re compatible with a variety of PC for-

mats, including VGA and SVGA signals up

to 85 Hz, and XGA (1024x768) signals at

60 Hz.

The rear panel includes a 12 V trigger

output to control a screen, and jacks for an

optional wired connection to the infrared

(IR) remote control. There is also an RS-232

connector, which according to the manual is

used for service. The power cord plugs into

the rear panel.

DVI Compatibility

This is the first projector that I have test-

ed that has an HDMI input instead of a DVI

input. If you have a DVD player or set-top

box with a DVI output, they will work just

fine through the HDMI input. You simply

need an HDMI to DVI cable, or a passive

adapter. Monster Cable (www.monsterca-

ble.com) provided a DVI to HDMI adapter

($29.95) that plugs into the projector, so that

I could use my existing DVI cables. Monster

also has an HDMI to DVI adapter ($29.95)

that allows HDMI cables to be connected to

DVI sources, and they have a full line of

HDMI and HDMI to DVI cables.

The HDMI input accepts digital video

signals in the RGB, YCbCr (4:4:4), and

YCbCr (4:2:2) formats. The YCbCr (4:4:4)

format is part of the DVI standard, but is

seldom used. The YCbCr (4:2:2) format is

new to HDMI. A menu item is provided to

select the digital video format—Component

(YCbCr), RGB, or Auto. The latter automati-

cally selects the format provided by an

HDMI source. There is also a menu selec-

tion for RGB-Video (16-235) or RGB-PC (0

to 235) levels, which accurately maintains

the black level and white level without read-

justing those controls. The HDMI (DVI) input

is compatible with 1080i, 720p, 480i/p, and

576i/p digital video formats, and VGA

(59.94 Hz) digital-RGB signals. HDCP

decryption is provided for HDMI (DVI) sig-

nals that include copy protection.

I used the DPX-1100 with 480p, 720p,

and 1080i DVI signals from a Samsung SIR-

T165 HDTV Receiver and a V. Inc. Bravo-D2

DVD player (which will be reviewed in a

future issue of Widescreen Review). The for-

mer produces RGB-PC levels, while the lat-

ter produces RGB-Video levels. I also test-

ed the YCbCr (4:4:4), RGB-Video, and

RGB-PC formats with 1080i, 720p, 480p

and 480i signals from an AccuPel HDG-

3000 HD/SD/DVI Calibration Generator.

Controls

The remote control includes a spring-

loaded toggle switch to illuminate just six

of its buttons. On-screen menus are con-

t rolled with Menu and Escape buttons, a n d

a tilt-pad that provides cursor and Enter

functions. There are dedicated buttons for

the Zoom, Focus, Ve r tical (Lens) Position,

and Iris functions. There are also d e d i c a t e d

buttons to select each of the six inputs and

six memories. Other buttons include

Aspect (ratio), Pattern (calibration), Hide

( p i c t u r e), Still (picture), Input, Auto (sync

adjust), and Reset. There are three built-in

test patterns. The crosshatch/focus pattern

is useful to adjust vertical lens shift, focus,

keystone, and zoom size. There is also a

10-step grayscale pattern and a color bar

p a t t e r n .

A large control panel on the top-rear of

the projector duplicates the menu naviga-

tion controls, and provides Input, Pattern,

Lens Adjustment and Aspect buttons in

addition to a Standby/On button and indica-

tor. There are also lamp, temp, cover and

fan warning indicators. The lamp warning

indictor blinks after 2,000 hours of lamp

operation. The 270W SHP lamp is user

replaceable and priced at $649.95.

Menu Functions

The DPX-1100 reprises the excellent on-

screen menu system of the DPX-1000. The

Menu window has four menu groups that

open below the menu bar. The menu

groups are Image, Signal, Initial, and Setup.

The menu window also displays the current

Input and Memory number. The entire Menu

window can be moved anywhere on the

screen while making adjustments.

The Image menu includes Black Level

(Brightness), White Level (Contrast),

Gamma, (Color) Saturation, Hue, Sharpness

Type and Gain, Color Adjustment, White

Peaking, Iris, and Level Adjustment.

Individual parameters can be reset to the

factory setting by pressing the Reset button

on the remote control when an item is

selected in a menu. If the Enter button is

pressed when the Menu window isn’t on

screen, the Image menu items can be
