The video card will sense which one is connected to a monitor and use it automatically. DVI outputs also can sense when a monitor is connected so you can use any DVI output. But DVI can get a bit complicated because different DVI outputs can have different capabilities. It’s quite common for one DVI output to be able to support higher resolution monitors than another DVI output. Many video cards have one single link DVI output and one dual link DVI output. You can read more about single and dual link DVI on this page. If you need to use a dual link DVI output and your video card only has one of them then you’ll need to consult the video card documentation on which DVI output supports dual link.
Some video cards draw too much power to get it from the expansion slot. They need one or (yikes!) two power cables to provide enough wattage.
Both DVI outputs will work with a high resolution monitor at lower resolutions but only the dual link DVI output will be able to drive the monitor at high resolution. One DVI output may use slower DVI transmitters built into the GPUwhereas the other DVI output may use a faster external silicon chip. If you have problems with one DVI output then try the other. Now you need to connect any auxiliary power cables to the video card.
Generally speaking, if you try to install the wrong display driver, it will give a "hardware not present" error and abort the installation. But there may be exceptions so be careful to install the right one. If you don’t have display drivers installed, then the "Display Properties" window doesn’t give you any useful information about your display adapter. Installing display drivers is usually fairly painless, but on occasion things go wrong. Before starting the process of updating a display driver, it’s a good idea to create a restore point as described here.
Most of the GPU manufacturers maintain driver archives which allow you to try out older drivers. Most current video cards have at least two VGA or DVI outputs. You can read in detail about VGA on this page and DVI on this page. All VGA outputs are the same and most video cards don’t care which one you use if you have more than one.

That way, if something goes wrong you can undo the changes you just made. You should always have administrator privileges before installing drivers . For older display adapters, the latest display drivers are not always the best. Once the GPU maker moves on to the next generation GPU, they reduce the amount of time they put into the drivers for their previous generation GPU and put most of their effort into the new generation. Unfortunately, they sometimes bring out drivers which improve things for their newer GPU models but cause problems for their older ones. If you have an older card and have problems which are not fixed by the latest drivers, you scanner driver can sometimes fix the problems by rolling back to older drivers.
Most display drivers currently come in the form of "unified drivers". That means that there is a single program which contains the drivers for a whole range of display adapters. Most unified drivers automatically recognize the display adapter and install the appropriate drivers. The display adapter must be in the computer when you install the display drivers.
