Video Problem

By supportoranges ·
While it is understandable that an video card needs drivers I was confused that the 'monitor' also needed drivers. This became apparent when I deleted all of the monitors listed in device manager and rebooted. pNp said it found a new monitor and insisted on locating drivers. Why is there a need for drivers for a monitor when the drivers for the adapter are already loaded? I'm a tech newbie.

Video Problem

The monitor is another hardware device.

Instead of being connected directly to the motherboard, like the video card, it is connected to the video card.

Many devices in your PC are chained together. Each device in the chain needs it's own driver.

To see this more clearly, open device manager and click on view devices by connection.

As to the specifics of a monitor driver, Windows needs to know the re-fresh rates and resolutions supported by the monitor so that it does not send a signal to the monitor that could damage the circuitry inside the monitor.

With no monitor driver installed, Windows defaults to the lowest resolution VGA setting.
(16 colors, 640 X 480 pixels)

Some monitors have special functions that can only be accessed by installing the manufactures driver.

You can think of drivers as road maps, and devices as cities.
The cables and motherboard sockets are highways that connect the cities to each other.

Once you travel down the highway and enter a new city, you need a map to find your way around.
The first time you go to a new city, you need another new map.

If the city is in a new country, you need to know the local laws.

Drivers tell Windows where to send data for the device to function, what commands are supported, and what it can do with the device.

I like your analogy, TheChas. I have never heard it put that way and it is an excellent explaination. . BTW, do you know Bill Gate's email address? There are a few things I wish to discuss with him. *smile*

The monitor does not need a driver to work. To use the advanced features or best resolution and colors of a monitor then you may need to install the MFG. drivers. Many monitors do not come with drivers.

Granted, MOST (PnP) monitors don't need MFG drivers, but if you have any plans of changing your refresh rate and/or utilizing high resolutions, it is in your best interest to use them if available. If you are using a flat-panel, good luck without them. Good rule of thumb - if a device has drivers available, use them; you can't go wrong

Afterthought--if you do any video or photo editing, colors probably won't come out right w/o correct drivers. OK, I think that's all...
