HD800 Basic Operation

Typical usage of an HD800 is to allow users to diagnose specific resolution, video timing, EDID and color space issues in any DVI
or HDMI video system. It features an HDMI output as well as an HDMI pass through to easily switch between test patterns and
content from any other digital sources, while also giving the ability to read the EDID from the input source and displaying it on the
display. It can also perform a cable test on any HDMI cable.

USE #1

AT-HDSync Scenarios

Typical placement of an HDSync is between source and display that is having HDMI troubleshooting issues. In a bigger HDMI
system (HDMI Matrix, AV receivers, and/or multiple HDMI splitters/repeaters/switchers, etc) Atlona recommends to still place
HDSync directly after source as a pass-thru conguration.

HDSync Scenarios Explained

Troubleshooting Issue #1

Two or more sources hooked up to one display

Challenge: Customer connects both a Set-Top Box and a Blu-Ray

player to a Display, on two different inputs on TV (Fig.1). Blu­Ray player always works, but set-top box is constantly displaying
“error” signal. Powering down temporarily solves the issue, but
as soon as customer switchers from Blu-Ray to Set-top box and
back again, error occurs.

Solution: HDSync. Root cause is the set-top box as a source
(Fig.1). The set-top box must support a special function of HDCP
called “HotPlug ON” in standby mode. If the source does not

support it, the HDMI connection will be inactive and unable to

re-handshake to TV.

Atlona’s HDSync maintains an always on, “HotPlug ON”
connection with HDMI, thus keeping your connection live to the
TV. When your input source says “no Sync” think HDSync!

Troubleshooting Issue #2

A/V Repeater hooked up in-between source and TV

Challenge: Customer connects one source (media player, set-top

box, etc) directly to a display with an HDMI cable, and it works!
As soon as something is introduced in the middle however (A/V
receiver, Matrix switch, distribution amplier, etc) (Fig. 2), an error
occurs on TV in form of snow or no picture. The EDID of the
Display is not correctly exchanged, so the error occurs.

Solution: Use an HDSync to re-capture the EDID of the display
(Fig. 2), and present it again to the source, or use on of HDSync’s
position-6 to record EDID’s to match your source content.

Troubleshooting Issue #3

Multiple sources hooked up to switcher/splitter/AV Receiver
and to multiple TV’s

Challenge: Customer connects multiple sources (media players,

set-top boxes, Blu-Rays, etc) directly to a middle point (splitter,
switcher, AV Receiver, etc) then is split/routed to multiple
displays! (Fig. 3) System only works in a particular sequence or
combination of sources and displays. Error is displayed on TV, or
source, or both. Possible root problem: the EDID of the Display is
not correctly exchanged, so the error occurs.

Solution: First use an HDSync in front of the source which is

giving errors; this will let you block out all EDIDs in the system.

(Fig. 3) Try out the appropriate mode that matches your
equipment as found on page 6 (1080p - 2Ch audio, 1080p ­Multichannel audio, etc). If that doesn’t work, then record the

EDID manually from the HDMI monitor as found at the top of

page 6; once recorded, plug HDSync back in front of the source.

Read the EDID manually from an HDMI monitor or projector

• Connect the HDMI display device to the HDSync via the HDMI port labeled display.

• Plug in the 5V DC power supply unit.

• Set HDSync to MODE 6.

• The EDID reading sequence is done when the green LED stops blinking.

• Leave the dial set on position-6.

NOTE: DO NOT let the rotary arrow pass by Mode 5, which will erase the EDID just learned, and restore the default EDID

HDSync Dial Modes:
