About Monitor Compatibility
The HDP is designed to work with most DVI-D monitors. The HDP uses the industry
standard EDID communication protocol (within the DVI link) to communicate with
the monitor, and then adjust the DIP’s internal scaling engine to scale the input video
to the native resolution of the monitor. However, due to the hundreds of variations of
DVI formats currently in use, proper operation with all monitors cannot be
guaranteed.
The HDP has 2 modes of operation that occur automatically, depending on what
monitor it is attached to: Recommended Monitor Mode and VESA Mode.
Recommended Monitor mode
For recommended monitors, there is custom firmware that will provide an accurate
frame-locked image for all supported SDI and HD-SDI input formats. The HDP
automatically determines the monitor it is connected to.
Recommended Monitors
• Apple 23" HD Cinema, model M9178LL/A (aluminum bezel)
• Sony 23", model SDM-P234
• Viewsonic VP231wb
• Dell 2405FPW
• Barco LC-42 (supported on HDP serial numbers H05019 or higher) 1
• Barco LC-47 (supported on HDP serial numbers H05019 or higher) 1
• Westinghouse LVM-37wl 1
Automatic 1080p Support 1
Monitors that report 1920x1080 in their “Prefered Timing Mode” section of EDID
readback will receive a 1920x1080p signal from the HDP.
Manual 1080p Support 1
The HDP can be configured manually for 1080p. This is discussed under “User
Controls” later in this manual.

Many manufacturers claim to display 1080p50 or 1080p60. This is often misleading.
While it is true that the image they present is at 1080p50 or 1080p60, this does not
necessarily mean that the DVI input will accept a 1080p50 or 1080p60 signal. The
Recommended monitors

noted here (Barco LC-43, LC47, and Westinghouse
LVM-37wl) are known to accept 1080p at 50/59.94/60Hz.
