1.3.4 Input Video Specifications

The following input video resolutions are supported on the HDMI and OpenLDI interfaces. These input video resolutions are programmed in the Extended Display Identification Data (EDID) EEPROM for the EVM's HDMI interface allowing a connected computer to read the supported resolutions and timing. Note that some computers are not able to output all of these resolutions.

Table 1-5 Supported Resolutions
Feature 0.46" Non-Diamond Down Sampling (non-DDS) Mode - HL 0.46" Non-Diamond Down Sampling (non-DDS) Mode - HUD 0.46" Diamond Down Sampling (DDS) Mode - HUD
EVM Part Number DLP4621Q1EVM DLP4620SQ1EVM DLP4620SQ1EVM
Supported Resolutions 960×480, 480×240 960×960, 960×480, 480×240 1358×566, 1220×610
480×240 YES YES N/A
960×480 YES YES N/A
960×960 N/A YES N/A
1358×566 N/A N/A YES
1220×610 N/A N/A YES

The input source timing specified in the EVM's HDMI interface EDID are specified in Table 2-6. These timing parameters are also recommended for the OpenLDI interface.
