Open GPU kernel modules versus Proprietary drivers

Select the display and press Unload EDID.Warning: If you plan to replace your card with a more recent one, it's recommended that you uninstall the NVidia DDX driver (reverting back to modesetting DDX driver (newer default) or nouveau DDX driver (older optional)) before upgrading your hardware. If you load the EDID onto a DVI port but later attach an HDMI display you may see two displays attached to the same physical display (only one display can be active at any one time). Each physical port on the Quadro Card supports different connection types:įor example a Display Port can support: VGA, DVI-D, DisplayPort and HDMI connections If you load the EDID onto a port that does not have a display attached make sure you select the correct port.

View system topology page will indicate it is reading the EDID from file by showing 'E' logo and 'EDID (File)' beside the display. Press Cancel to exit the Manage EDID menuħ. Press Load EDID - The display name may change if you loaded a monitor EDID with a different nameĦ. Select the port or ports(s) you want to load the EDID to.'Ĥ. Select the EDID you want to load using the 'Browse button'ģ.

Go to NVIDIA Control Panel -> View system topology page -> EDIDĢ.

You can use it to fake a display being attached for testing.

With the EDID being read from file the OS will always think the display is attached.

In Windows 7 and 8 if you unplug a display that will trigger a hot plug event which may reconfigure your displays.

In A/V environments with switchers and/or cable extenders the display EDID may be lost.

Managing the EDID is useful in the following use cases: What are the benefits to Managing the EDID? Instead of reading the EDID from the display we can now read it each time from file. The NVIDIA Quadro Driver can store the EDID from a display and save it to file. From this information it will determine the preferred display timings and supported modes. The NVIDIA driver reads the display EDID when it detects an attached display. EDID is information about supported display resolutions and modes that is stored on display such as Monitor, TV or projector.
