You will need
- the video connection cable adapter.
Usually video cards computers contain two slots. Possible combination of VGA+DVI or VGA+HDMI. Modern monitors are VGA and DVI ports.
You may have to use several adapters to connect a second monitor. The fact is that if both your displays are only present ports VGA (analog signal), and the video card has VGA and HDMI, you'll need an adapter HDMI-DVI and DVI-VGA.
Fortunately, there are special cables DVI-HDMI. Their use will allow not to connect the two adapters with each other. Purchase the required cables and adapters (if needed).
Connect both monitors to the graphics card of the computer and turn it on. Wait for the download of the operating system. Most likely, both monitors will be sent the same signal.
It is worth noting one important caveat: not all display adapters support dual channel mode. This means that only one monitor can be active.
We consider the situation when both displays will work simultaneously. Adjust the image transmitted to the screens in two ways. Open the control panel (this item is located in the start menu) and select "appearance and personalization".
Go to "screen Resolution". Activate the function "Duplicate displays". In this case both monitor will show identical picture. Usually this function is used when connecting the TV to watch high-definition video.
Select "Extend these displays". In this configuration displays, you can simultaneously use both screens independently of each other. Example: to run the game on one of them and watch videos on other. Remember that this method requires certain resources and is not well suited for "weak" computers.
Advice 2 : How to use 2 monitors
Some people actively using personal computers, sorely lacking workspace one of display. In such cases, it is recommended to connect a second monitor for simultaneous use of the devices.
You will need
- 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.
