How to connect a monitor to the laptop? This is quite a simple matter! Many people use an additional monitor, or a TV via a laptop, to watch movies on the big screen, or to expand the workspace. This article will help you understand the main connection technologies, and decide what connection you will use.
What interfaces are used to connect the monitor to the laptop?
Before you run to the store for cables andadapters, to connect the monitor, we determine what outputs are available on the laptop and monitor. There are three types of interfaces used in computers for video transmission:
- VGA- the most simple and low-quality interface. It is used on almost all laptops, netbooks, and monitors.VGAtransmits an analog signal, so there is more noise in it, and a lower resolution of the image, unlike the others.
- DVI- rarely used on laptops, but increasingly on stationary PCs, and monitors, characterizes the digital image of a higher quality.
- HDMI- At the moment the most popular interface,because of the big possibilities, besides video, as it is capable to transfer and a sound 5: 1 that does its very convenient for connection to the TV and other devices of such type.
Consider the possible combinations
VGA to VGA
This is the most standard situation, the laptop and monitor are equipped withVGAconnector. Such cables are the cheapest, and are sold in all computer stores.
VGA to DVI
When you connectVGAtoDVIThe conversion of a digital signal into an analog signal is required, which entails a loss of quality. If this option suits you, the adaptersVGA-DVI, are very common.
VGA - HDMI
One of the most difficult situations, when on one device onlyHDMI, on the other, onlyVGA. The task is not simple, but it can be solved by purchaseadapter. This adapter costs much more than in all other situations, and there are not many where it is sold. Consequently, the method is not effective, since image quality will be low due to the useVGA, and adapters are expensive.
SituationHDMI-DVI, a good situation, since both of these interfaces use a digital signal, and are perfectly compatible with each other. The image quality is much better (in comparison withVGA) and without noise. The disadvantage is only thatDVIdoes not support the transfer of sound, but when connecting the monitor to a laptop, this can be neglected.
If the laptop and monitor use the interfaceHDMI, you can boldly clap your hands! This is currently the best of the ways, since the picture will be the best possible.
How to connect a monitor to a laptop?
And here we come with you to the truth, at this stagewe already have everything we need, we determined the types of connectors on the devices, chose the best method of connection, and ran to the nearest computer stand with a cable.
First, shut down the computer, some computers determine the presence of a second monitor when turned on.
Connect the devices with a cable, and run.
In a standard situation, the laptop will duplicateimage on the computer and on the monitor. You can change this situation in the graphics settings of your operating system, or by hotkeys on the laptop. Usually this is a combination of the keys "Fn" + The function key indicated by the monitor icon (standard "f4" or "f5"). After that, you can choose from four options for using the monitor:
- Duplicate the image;
- Use only the monitor;
- Use only computer display;
- Expansion of the main display by the monitor;
Can I use the laptop display as a PC monitor?
The question is quite interesting and has nounambiguous answer. The laptop display is not intended for use by other devices. Laptops are not equipped with video inputs, to transfer images to them. However, you can use and connect your laptop as a second monitor using a local connection. Was written quite an interesting utilityMaxiVistawhich configures remote access from the laptop to the computer so that the laptop turns into a second monitor. The utility is not very well known, and besides it is not free.
