Pin 12, ID1, of the VGA connector is used as the data pin of the I²C bus, and the formerly-unused pin 15 is the I²C clock. Pin 9, previously used as a mechanical key, supplies +5V DC power (up to 50mA) to power the EEPROM. With this, the host can read the EDID even if the monitor is powered off.
Became a nearly ubiquitous analog computer display connector after first being introduced with IBM x86 machines. Older VGA connectors were DE-9 (9-pin). The modern DE-15 connector can carry Display Data Channel to allow the monitor to communicate with the graphics card, and optionally vice versa. [1] Being replaced by DVI from 1999 onward. DB13W3
The MHL TMDS data lane (purple & green) uses the differential pair present in both USB 2.0 (Data− & Data+) and HDMI (TMDS Data0− & Data0+). The MHL Control Bus repurposes the USB On-The-Go ID (pin 4), and the HDMI Hot Plug Detect (pin 19), while the pins for power & ground match their original assignment for both.
"Plugged into a Roku Ready device, the Roku Streaming Stick offers instant access to movies, TV shows, live sports, music, games and more from over 600 entertainment channels available on the Roku ...
The Display Data Channel or DDC is a digital connection between a computer display and a graphics adapter that allows the display to communicate its specifications to the adapter. The standard was created by VESA .
The Display Data Channel (DDC) is a VESA standard communications channel based on the I 2 C bus specification. HDMI specifically requires the device implement the Enhanced Display Data Channel (E-DDC), which is used by the HDMI source device to read the E-EDID data from the HDMI sink device to learn what audio/video formats it can take.
Extended Display Identification Data (EDID) and Enhanced EDID (E-EDID) are metadata formats for display devices to describe their capabilities to a video source (e.g., graphics card or set-top box). The data format is defined by a standard published by the Video Electronics Standards Association (VESA). The EDID data structure includes ...
I’ve used the traditional cable boxes with hard drive DVRs for years, in combination with either Roku, Amazon Fire Stick or SmartTV for streaming, so I was curious to see how the Xumo compared.
