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
VESA Mode
For DVI-D monitors not on the recommended list, the HDP will use standard VESA
timing based on the particular monitors “preferred timing”—as determined by the
EDID communication with the monitor. Because VESA timing standards are not
based on video formats, the HDP cannot frame lock to the input video and will operate
like a frame synchronizer - it will frame rate convert by adding or dropping frames as
needed. If a particular monitor reports a preferred timing mode that is not supported
by the HDP, the HDP will default to standard XGA (1024 x 768 60Hz) timing.
Monitors tested for Compatibility in VESA Mode:
• HP HPL2335
• Samsung 170T
• Samsung 213T
