Troubleshooting
This chapter provides suggested solutions to common problems that may occur when installing and using
the DVP1080HD.
Connecting the processor to the display
Which output scan rate should I choose for my display?
The appropriate output scan rate selection is usually determined by the actual native pixel
density of a digital display device, or the physical CRT size of an analogue display device
(7", 8" or 9" CRT).
Each display device will specify their individual video/computer input capabilities. All display
devices will list their specific video/computer input specifications within the User's Manual,
and are typically located within a "Table of Supported Resolutions", or under similar
nomenclature.
The following represent basic examples for possible output scan rate selections:
Display Type
Display resolution
Plasma TV
1366 x 768
1366 x 768
Digital projector
CRT projector
7" CRT
8" CRT
9" CRT
CRT rear screen
480 i/p, 1080i, or 720p
Note: Occasionally, a digital display device may not actually accept the signal received
from the processor at its native pixel resolution. Choose a standard DTV signal in this
instance, such as 1280x720 (default setting), or 1920x540 (1080i equivalent).
There are sparkles appearing throughout the image when using
the DVI output
Cable length is too long to support the output resolution selected on the processor
• Sparkles may occur if the resolution selected on the DVP-1080 processor has exceeded
the ability of the DVI cable to transmit all of the video data (missing bits = sparkles).
This is directly dependent upon cable quality (contact cable manufacturer regarding
length to resolution specifications).
• Unassisted DVI cable lengths to 50ft (15.24m) have been achieved with resolutions of
1024p and lower.
• Cable lengths of 50ft (15.24m), or greater, may require a DVI to Fibre Optic cable
connection between the processor and display for resolutions higher than 1024p;

You can also use a Meridian HDMAX 121 extender/booster at the display end to solve
1366 x 768
problems like this. Contact your Meridian authorised dealer for details.
1280 x 720
Can the DVP1080 output both an analogue and a digital signal
1920 x 540 or 1280 x 720
simultaneously?
1280 x 720 or 1440 x 960
1440 x 960 or 1920 x 1080
Yes. Four potential SET: ACTIVE OUTPUT modes are available through the DVP-1080
1920 x 540p or 1280 x 720p
SETUP MENU:
Mode
ANALOG RGB + DVI
ANALOG RGB
