An actual problem for many users onToday is the expansion of the image from the personal computer to the home plasma display. “We connect the TV to the computer via HDMI, but there is no image,” - this is exactly the negative from the mouth of the owners of computer equipment.
In this article, the reader will get acquainted not only withmethod of connecting an additional display to a PC or laptop, but also learns about the correct hardware settings. Also, he will be interested in the recommendations of experts in the field of IT technologies.
About the pursued goals
The larger the diagonal of the liquid crystalthe screen, the more comfortable viewing of multimedia and better image detail in games and software. A film on TV from a computer will allow you to see the smallest details, and a fan of dynamic toys will feel the reality of the events on the plasma screen. In fact, there are many advantages of using such a symbiosis, and they all concern the comfortable work or leisure of the user.
In recent years, many usersinterested in internet tv. Why pay money to the provider if you can watch your favorite channels for free from the official website of the television company? Therefore, the question: "How to bring a computer to the TV?" Sounds increasingly in the media. That's just with ready-made solutions while things are bad.
Computer hardware features
Start better with technical capabilitiespersonal computer or laptop. The fact is that it is not enough to buy an HDMI cable for a computer. You can connect to the TV only if you have the corresponding digital video output on the PC. Therefore, the user needs to familiarize himself with all the outputs of the system unit and find the desired port. It can be located on the video card or on the motherboard at the computer and at one of the ends of the mobile laptop.
There are devices that are missingHDMI connector. It is quite possible to find on old PCs analog video output VGA (D-Sub) or digital DVI ports with DisplayPort. It all depends more on the TV, in which there must be similar inputs. Having picked up the necessary cable for the TV, you will always find an opportunity to display the image from the computer.
TV availability
But in modern liquid crystalthere are no problems with HDMI ports - all manufacturers provide their equipment with a high-demand interface. Often they are not limited to one port at the factory and provide an opportunity for a user to connect several sources to display an image via HDMI.
Large size liquid crystal displayshave a slightly different problem. We are talking about the resolution of the reproduced image and frame rate. Before connecting a computer and a TV via HDMI, the user needs to familiarize himself with the technical characteristics of both devices, compare their video transmission capabilities and find a parameter that will be supported by both the plasma and the PC. Often, all equipment manufacturers strive to ensure that the equipment supports FullHD resolution (1920x1080) at a frequency of 60 Hz. True, there are exceptions that create problems for users.
The work of devices of different generations
In situations involving the connection of twodevices with different interfaces (HDMI, VGA), often users wonder why the computer does not see the TV through HDMI. Everything is explained simply - it is impossible to connect the equipment of different generations, combining analog and digital signal with one cable. In such situations, no adapter will solve the problem - you need a converter that can decode the signal at the hardware level.
Fortunately there are foreign auctionsready-made solutions that can solve all the problems of users with the transmission of video between devices of different generations. The cost of one converter is in the range of 20-30 y. e., and this attracts a potential buyer. All the necessary cables for video transmission are always included with the converter, so the problem solving algorithm is simple: we buy a converter and connect the TV to the computer via HDMI.
When there is no necessary interface
Not all computers and televisions have an HDMI port -it is a fact. But you shouldn’t get upset before the time, because with obsolete devices the problem can always be solved. The fact is that the old equipment is focused on the transmission of analog signal. Let this technology lag behind in image quality, but with the compatibility of different standards it has an order of magnitude less problems. Combining S-Vidio, VGA or RCA interfaces is much easier than converting an analog signal into a number.
Users only need to buy a cable forTV and connect both devices. There are many inconveniences that users will have to face. First, the sound cannot be transmitted through the interface cable. Accordingly, you need to buy another cable. Secondly, during the operation, the sound card of the computer or laptop will not be able to create an individual audio stream for the TV. Accordingly, the convenience of sharing a computer and TV can be forgotten.
The right approach to buying a cable
Problems may arise with the user and withselecting the wrong HDMI cable. The fact is that the digital video signal is not capable of being transmitted over long distances by cable without loss of quality. Therefore, the future owner needs to decide on the length before buying the HDMI cable for the computer to the TV.
Главное - всегда помнить, что чем длиннее quality cable, the higher its cost. It is necessary to measure the distance between the PC and the liquid crystal display (of course, not in direct line of sight, but with regard to installation) and find the appropriate cable in the market. Yes, it is customary for buyers to buy wires with a margin, but it should be small, because often surpluses are rarely in demand - more often they just collect dust at the TV or computer. The main thing here is to find a middle ground in terms of the “cost - cable length” ratio.
Real manufacturers offers
Cable for HDMI-HDMI TVchoose the market is not easy. Any buyer can be convinced of this by himself, just look at the prices and range. It is logical to assume that expensive accessories are expensive only because they are made by serious brands. This is true, but, as practice shows, the more expensive the HDMI cable, the less likely it is that the video signal will deteriorate at a great distance. In fact, you have to pay for quality. Chinese consumer goods have no place in the domestic market.
IT experts recommend turningattention to the brand name (for example, Prolink, Cablexpert, Viewcon, Belkin), and also focus on the quality of the winding and the presence of ferrite filters near the connectors (barrels near the contacts). If you need an HDMI cable that is longer than 30 meters, then the user cannot do without a signal amplifier. The device is expensive, but copes with its tasks by 100%.
Physical connection of two devices
This article is not about the potential difference ofschool physics course, but the user still needs to know that there is a small electrical charge on the video ports when the equipment is turned on. Naturally, when two devices are connected with a large charge, they will transfer energy through the cable to the port of the connected device. Often more powerful is the TV, which, when connected, burns the output on the video card of the computer. Therefore, before connecting the computer to the TV via HDMI, you need to de-energize one of the devices (remove the plug from the outlet). Naturally, this problem bypasses all users who have a grounding in the house.
One more trouble that canto encounter a buyer, this is the absence of a video signal when connecting a cable or transmitting an image with interference. No need to touch the settings of the TV or computer - 99% of the problem is in poor-quality cable. Need to replace it. In general, experts recommend checking the HDMI cable directly in the store to avoid connection problems.
TV settings
The owner of the LCD is notIt will be difficult on the remote control of the device to press the “Source” button and select the desired signal source. All ports on the TV panel are registered and numbered, so it remains only to combine the software with the hardware. No need to expect that the image from the PC will immediately appear on the screen. The main thing here is to bring the display into readiness for receiving the video signal. This completes the setting for connecting the TV to the computer via HDMI. It remains only to configure the video output of a PC or laptop.
Many users are home owners.cinemas, receivers, TV tuners and other video and audio equipment, which is connected to the LCD TV. Naturally, a situation may arise when all the HDMI ports are occupied. Many users are unlikely to physically rearrange the HDMI cable when working with a computer, so a different solution is proposed. The video signal from the laptop can be transmitted to the tuner or receiver. In fact, there is no difference, as manufacturers use a single standard for transferring images via HDMI.
Modern platforms
Когда речь заходит об операционных системах Windows 10 or MacOS, there are practically no questions with setting. It is enough for the user to restart the computer in order for the device to detect and connect a new display. The more modern the equipment, the more efficient the automatic tuning takes place - often via HDMI from the computer to the TV the signal is transmitted in FullHD format with a frequency of 60-65 Hz.
Но бывают исключения, и связаны они в первую queue with video device driver. Therefore, no need to try to get the TV to work properly with the remote control, only fine-tuning the video card will help here. The main thing is to always remember that changing the parameters requires not global, but just one port, otherwise, by carelessness, you can destroy the signal to the PC monitor, which will be very difficult to restore.
Work with drivers
Making the TV work like a monitorcomputer via HDMI, though difficult, but quite real. To do this, there are many ways with which the reader will get to know. Owners of Windows operating systems versions 7.8 and 10 need to go to the control panel and select the item "Display".
Перейдя в закладку «Настройка параметров экрана», the user will find that the operating system has already identified the connected TV, however, the image does not yet transmit to it. The Multiple Displays option allows you to connect your TV as an additional monitor to your computer. The list contains several options from which the user is offered to make a choice:
- Duplicate these screens. The contents of the desktop are displayed on the TV screen, and all actions taken by the user will be visible on both displays.
- Expand these screens. The most interesting setting that allows you to virtually increase the area of the desktop (and, both vertically and horizontally).
- Show desktop on screen no. Manual port assignment for video output is not claimed by users.
Features driver settings
Signal to the TV is easy, but set uppicture quality and transfer sound from the computer to the TV is not easy. First, you need to decide on the extension of the desktop - diagonally or vertically. Experts recommend that you navigate the physical location of the TV in a room relative to the PC monitor. On the control panel, in the “Screen resolution” menu, you need to place the icon No. 2 relative to the icon No. 1 with the mouse so that it is convenient to move desktop objects between the displays.
The second step is setting the screen resolution.tv set The main thing here is to choose a parameter that is supported by the connected display, otherwise it will fail, and the port for video output will turn off. By clicking the “Advanced Settings” button, the user can select the display refresh rate, but IT experts do not recommend changing the frequency unless the video card and TV support 4K (144 Hz). After making all the settings, you need to save the changes and exit the control panel.
Tricks with sound transmission
Всем пользователям известно, что HDMI-кабель It transmits not only the high-quality image, but also the sound, only the corresponding setting in the display resolution settings is missing. With audio transmission, everything is simple - at the hardware level, the sound enters an additional screen along with the video. That is, it is enough for the user to move the video player window to the TV display with the mouse. In the speakers of the computer, the sound is turned off, and in the speakers of the TV is activated.
It is worth noting that a mobile device orcomputer capable at the hardware level to support multiple video devices connected via HDMI, transfer to them a different image and provide them with sound. True, there are exceptions, and they depend on the video card and sound card. Low-end devices sometimes fail, they simply do not have enough power to process the digital video signal and sound quality.
Alternative driver configuration
Not only Windows can be customizedtransfer video to the TV screen. Owners of discrete video cards are given the opportunity to provide high-quality transmission through a video adapter driver (Nvidia or Radeon). The setting algorithm is the same: we connect the TV to the computer via HDMI and install the HDMI signal source using the remote control.
But then the proprietary software is usedproviding the manufacturer of the video card. Go to the control panel of the application Nvidia Geforce Experience or AMD Catalyst Control Center, you need to find the tab "Display". One of the sub-items of this menu is responsible for setting up multiple displays.
Feedback from users
Often when you connect the TV to a computer orlaptop owners have problems that they try to solve together in the media. Most of the negative, which is found in the reviews, is associated with a low-quality HDMI cable, which was purchased at foreign auctions, or in stores at a low price. Greedy man pays twice - all users who decide to save on the purchase of an HDMI cable need to be aware of this.
After adjusting the display settings and savingdid the image on the main monitor disappear? This is the second problem that users often encounter. The reason is quite simple - the main monitor parameters have been changed. There is one recommendation - connecting your TV to a computer, you need to control your actions. At number 1 in the system is always the main monitor - its settings can not be changed. With the rest of the numbers (2,3,4) you can do anything.
Finally
Yes, in order to make yourself comfortable,the user needs a little time and investment. Without this, simply can not do. There is an instruction in which all actions are registered, they need to be carried out clearly:
- we buy an HDMI cable;
- We connect the TV to the computer via HDMI;
- configure the video driver;
- enjoy watching.
The algorithm is simple, but there is a lot of work to do.In fact, there is nothing difficult, the main thing is to follow the recommendations of experts and perform strictly specified actions. Only after receiving the image from a computer or laptop on the TV screen and making sure that there is a transmission of sound, you can go into advanced options and fine-tune it.
