How to setup other resolution timing that not in EDID?ġ.

We can get below information by decoding full EDID structureĪnalog Display Input: Input Voltage - 0.700V/0.300VĭPMS: Active yes, Suspend yes, Standby yesġ 1328 1440 1688 1024 1025 1028 1066 +HSync +VSync Multiply by 8, then add 248 for actual valueĪspect ratio. Stereo Mode (bit 0) (unused if 6-5 are 00)Īnd we need get refresh rate from EDID Standard timing identification ( byte38-53)įirst byte: Horizontal resolution. We read first two bytes of the block, we can judge it is DTD if they are nonzero, some monitor manufacturer may have more than one DTD, that need us to choose which one is most suitable.Ġ x30 0x2A 0x00 0x98 0x51 0x00 0x2A 0x40 0x30 0x70 0x13 0x00 0x78 0x2D 0x11 0x00 0x00 0x1Eīyte0,1 is pixle clock, unit 10Khz,MSB in byte1, LSB in byte 0,Ġx2A30=10800, that is 10800x10Khz=108Mhz.īyte2 and byte4 upper 4 bites is Horizontal active,īyte5 and byte7 upper 4 bits is Vertical activeīyte3 and byte4 lower 4 bits is Horizontal bankingīyte6 and byte7 lower 4 bits is Vertical bankingīyte8 and byte11(bit7-6) is Horizontal sync offsetīyte9 and byte11(bit5-4) is Horizontal sync pulse widthīyte10 upper 4 bits and byte11(bit3-2) is Vertical sync offsetīyte10 lower 4 bits and byte11(bit1-0) is Vertical sync pulse width DTD is in first Descriptor Block in normal way, but it can be in any of the four.
We care about ” Descriptor Blocks“, There are four "Descritor Blocks" from byte 54(Byte 0 is first byte), 18 bytes per block,we call them DTD. We only focus on those video timing relate information. 2.EDID 1.3 data formatĮDID has 128 bytes, detail information please refer.

The EDID includes manufacturer name and serial number, product type, phosphoror filter type, timings supported by the display, display size, luminance data and (for digital displays only) pixel mapping data. EDID is defined by a standard published by the Video Electronics Standards Association (VESA). It is what enables a modern personal computer to know what kinds of monitors are connected to it. The information also call Extended display identification data ( EDID ), (EDID) is a data structure provided by a digital display to describe its capabilities to a video source (e.g.graphics card, Set-top box). In order to guarantee to set factory default resolution of that monitor, we need to get video timing information for monitor by DDC interface(usually I2C bus). We have product, need to connect difference monitor over VGA display port.
