This procedure covers Choosing RX Video Mode for XD614.
ADDERLink XD receivers contain an internal DisplayPort MST hub. On the XD614 models you can choose to either use it or bypass it. When bypassed (default setting), the full combined MST (Multi-Stream Transport) signal received from the transmitter is sent directly to video port 1. If the internal hub is engaged, then the first and second SST video streams (Single-Stream Transport) are decoded and sent to ports 1 and 2 respectively. The two modes are as follows:
• SST mode - This mode engages the internal hub and delivers the first and second (SST) video streams to the video ports on the receiver.
• MST mode - (Default) This mode bypasses the internal hub and delivers all four possible (MST) video streams directly to video port 1 on the receiver. Port 2 is disabled. Connect to either MST-compliant displays or an MST hub.
To choose the receiver video mode
1. Using your console keyboard attached to the receiver module, press (and release) the Ctrl key three times in quick succession (either of the keyboard’s Ctrl keys can be used). In response, the three keyboard indicators will all flash, once per second.
2. Press 1 to raise the OSD.
3. Press the CTRL key three times again.
4. Press the numeric key located above the main section of the keyboard (not the numeric keypad) which represents the required mode:
• 8 for SST mode,
• 9 for MST mode.
The current mode will be displayed on the Dashboard next to the link speed, eg SST or MST:
5. Press the CTRL key three times again and then 1 to close the OSD.
Note
In certain MST environments, incorrect resolutions can sometimes be used, leading to the DisplayPort link bandwidth being exceeded. This issue can result in one or more displays losing video output.
While the PC should ideally prevent this, another solution is to limit the EDIDs of the connected displays at the receiver (Rx).
To set EDID limiting mode (XD614 only)
1. Using your console keyboard attached to the receiver module, press (and release) the Ctrl key three times in quick succession (either of the keyboard’s Ctrl keys can be used). In response, the three keyboard indicators will all flash, once per second.
2. Press 1 to raise the OSD.
3. Press the CTRL key three times again.
4. Press the numeric key 3(Three) located above the main section of the keyboard (not the numeric keypad) to cycle through to the desired mode:
To simplify, the EDID limitation mode options are as follows:
- 4K: EDIDs are not limited, allowing each display to support up to 4K resolution. Streams 0 and 1 support 4K, while streams 2 and 3 support HD. This option enables the user to use one display at maximum resolution or configure the PC output without any limits.
- 2K: EDIDs are limited to 2.5K resolutions (maximum 2560x1600). This option allows the user to use two displays at maximum resolution.
- HD: EDIDs are limited to HD resolutions (maximum 1920x1200). This option allows the user to use four displays at maximum resolution.
The select mode will be displayed at the top right hand side of the OSD.
5. Press the CTRL key three times again and then 1 to close the OSD.
