This package contains a GOP driver for Universal USB-connected docks containing the DisplayLink DL-6xxx chip or newer.
The driver supports the following resolutions:
640 x 480 @ 60Hz
800 x 600 @ 60Hz
1024x768 @ 60Hz
1360x768 @ 60Hz
1280x960 @ 60Hz
1280x1024 @ 60Hz
1600x900 @ 60Hz
1400x1050 @ 60Hz
1600x1200 @ 60Hz
1920x1080 @ 60Hz
Note that the list of resolutions advertised by the driver may be smaller than this if a connected monitor does not support a particular resolution. The driver interrogates connected monitors to see which modes can be supported.It is the responsibility of the BIOS to select the video mode from this list which most closely matches its requirements. In some cases this may lead to the BIOS scaling its display.
The driver is limited to a maximum of ten frames per second. Some slower systems at higher screen resolutions may perform at a lower rate than this.
If multiple monitors are connected to the DisplayLinkdevice, the display will be duplicated (cloned) across all outputs at the same resolution. The resolution used will be limited by the capability of the monitor with the lowest specification.
The driver will support the connection of multiple DisplayLink devices. The exact behaviourof the system with multiple devices connected is defined by the rest of the BIOS; usually, the BIOS causes the displays to be duplicated (cloned) across all devices. Note that the system performance and frame rate will be affected by the number of DisplayLink devices connected.
The driver uses the EDID (Extended Display Identification Data) protocol to detect the list of resolutions that a monitor will support.In some monitors this may take some time, and occasionally no EDID information will be returned at all. In this case the driver will not be able to detect that there is a monitor connected. To improve the user experience in these cases, the driver will behave as if there is a monitor connected, and will fall back to presenting the full range of supported resolutions to the BIOS.
