- The connection cable of the monitor.
Select the new display which you can connect to your graphics card. For simple image optimization of the two displays is better to choose a monitor that supports the resolution used by the first display. Pay attention to the refresh rate of the screen. When working with two displays you will have to turn to look at both monitors. This can damage the eyesight.
Make sure that your video card supports dual-channel mode. Usually video cards have two or three outputs. Make sure that you will be able to connect the new monitor to the graphics card. Purchase the adapter, such as DVI-VGA if needed. Connect the second display to the selected port on the graphics card using a standard cable and adapter. Turn on the computer and both monitors.
After loading the operating system, configure the settings for the synchronous operation of displays. If you are using Windows Seven, click the right mouse button pointing the cursor on the desktop area. Select "screen Resolution". In the opened menu click "Find" and wait until the system will detect the second display.
Now select the graphics image of the desired monitor and activate the option "Make this main display". Now click the "Expand screen". This will allow you to use both monitors independently from each other.
If you will be running on the second monitor only Internet browser and similar programs, it is reasonable to change the display position. Select "Portrait" and click "Apply". Turn the monitor 90 degrees clockwise and secure it. Adjust the location of the displays relative to each other. To migrate a running program in the area of another monitor, move the cursor over the border of the first screen.
