- Multiple-monitor support is provided by Windows 2000 and later; therefore, display driver writers must not implement any special code to provide this support. Display drivers must be implemented without using global variables. All state must exist in the PDEV for a particular display driver.
- The Driver tab shows the driver as a Microsoft driver dated 6/21/2006, version 10.0.17134.1. The 'Driver Details' button opens a 'Driver File Details' window showing the driver file as 'C: WINDOWS system32 DRIVERS monitor.sys'. In the Driver tab, only the 'Driver Details' button is active; the others, including 'Update Driver', are grayed out.
- The DAQ software helps to diagnose hardware with complete I/O drivers. It also includes DAQ SDK and DAQ utility application software to control specific hardware interface.
The Driver Monitoring System, also known as Driver Attention Monitor, is a vehicle safety system first introduced by Toyota in 2006 for its and Lexus latest models. It was first offered in Japan on the GS 450h. The system's functions co-operate with the Pre-Collision System (PCS). The system uses infrared sensors to monitor driver attentiveness. The Driver Monitoring is a new system based on a camera to monitor driver alertness, that not only recognizes the driver, but also checks his or her level of vigilance. The purpose of the Driver Monitoring system is to alert the driver when signs of drowsiness or distraction are detected.
With an INF file you can override the Extended Display Identification Data (EDID) of any monitor. A sample INF file, Monsamp.inf, that shows how to do this was provided with the Windows Driver Kit (WDK) through Windows 7 (WDK version 7600). Monsamp.inf is reproduced here.
For info on how to use and modify Monsamp.inf, see Monitor INF File Sections.
Approaches to correcting EDIDs
All monitors, analog or digital, must support EDID, which contains info such as the monitor identifier, manufacturer data, hardware identifier, timing info, and so on. This data is stored in the monitor’s EEPROM in a format that is specified by the Video Electronics Standards Association (VESA).
Monitors provide the EDID to Microsoft Windows components, display drivers, and some user-mode applications. For example, during initialization the monitor driver queries the Windows Display Driver Model (WDDM) driver for its brightness query interface and device driver interface (DDI) support, which is in the EDID. Incorrect or invalid EDID info on the monitor’s EEPROM can therefore lead to problems such as setting incorrect display modes.
There are two approaches to correcting EDIDs:
- The standard solution is to have the customer send the monitor back to the manufacturer, who reflashes the EEPROM with the correct EDID and returns the monitor to the customer.
- A better solution, described here, is for the manufacturer to implement an INF file that contains the correct EDID info, and have the customer download it to the computer that's connected to the monitor. Windows extracts the updated EDID info from the INF and provides it to components instead of the info from the EEPROM EDID, effectively overriding the EEPROM EDID.
In addition to replacing the EDID info as described here, a vendor can provide an override for the monitor name and the preferred display resolution. Such an override is frequently made available to customers through Windows Update or digital media in the shipping box. Such an override receives higher precedence than the EDID override mentioned here. Guidelines for achieving this can be found in Monitor INF File Sections.
EDID format
EDID data is formatted as one or more 128-byte blocks:
- EDID version 1.0 through 1.2 consists of a single block of data, per the VESA specification.
- With EDID version 1.3 or enhanced EDID (E-EDID), manufacturers can specify one or more extension blocks in addition to the primary block.
Each block is numbered, starting with 0 for the initial block. To update EDID info, the manufacturer’s INF specifies the number of the block to be updated and provides 128 bytes of EDID data to replace the original block. The monitor driver obtains the updated data for the corrected blocks from the registry and uses the EEPROM data for the remaining blocks.
Updating an EDID
To update an EDID by using an INF:
The monitor manufacturer implements an INF that contains the updated EDID info and downloads the file to the user’s computer. This can be done through Windows Update or by shipping a CD with the monitor.
The monitor class installer extracts the updated EDID info from the INF and stores the info as values under this registry key:
Each EDID override is stored under a separate key. For example:
The monitor driver checks the registry during initialization and uses any EDID info that's stored there instead of the corresponding info on EEPROM. EDID info that has been added to the registry always takes precedence over EEPROM EDID info.
Windows components and user-mode apps use the updated EDID info.
Overriding an EDID with an INF
To override an EDID, include an AddReg directive in the INF for each block that you want to override, in the following format:
The block number is a zero-indexed value of the EDID block to override. The data bytes should be formatted as 128 hexadecimal integers that contain the binary EDID data. The '0x1' value after the block number is a flag indicating that this registry value contains binary data (FLG_ADDREG_BINVALUETYPE).
Manufacturers must update only those EDID blocks that are incorrect. The system obtains the remaining blocks from EEPROM. The following example shows the relevant sections of an INF that updates EDID blocks 0, 4, and 5. The monitor driver obtains blocks 1 - 3 and any extension blocks that follow block 5 from EEPROM:
For more info on INFs in general, and AddReg and DDInstall in particular, see Creating an INF File.
The Driver Monitoring System, also known as Driver Attention Monitor, is a vehicle safety system first introduced by Toyota in 2006 for its and Lexus latest models. It was first offered in Japan on the GS 450h. The system's functions co-operate with the Pre-Collision System (PCS).[1] The system uses infrared sensors to monitor driver attentiveness. Specifically, the Driver Monitoring System includes a CCDcamera placed on the steering column which tracks the face,[2] via infraredLED detectors.[3] If the driver is not paying attention to the road ahead and a dangerous situation is detected, the system will warn the driver by flashing lights, warning sounds. If no action is taken, the vehicle will apply the brakes (a warning alarm will sound followed by a brief automatic application of the braking system). This system is said to be the first of its kind.[2]
In 2008, the Toyota Crown system went further and can detect if the driver is becoming sleepy by monitoring the eyelids.[4][5]
In 2017, Cadillac released their Super Cruise system. Which allowed hands free driving at highway speeds on specially mapped highways. In order to ensure that the driver continued to pay attention to the road, they included Seeing Machines DMS, this was initially only available in the CT6.[6]
In 2019, BMW introduced a Extended Traffic Jam Assistant System [7] in almost its entire range of car models this allows driving at up to 37 mph
