When you connect the TV to an additional HDMI/DVI cable, the computer “downloads” the TV, but there is no image on the TV (HDMI mode is selected on the TV).
The current problem is mostly related to an unclear HDMI/DVI cable and it needs to be replaced.
Today, any user can use an additional HDMI cable, as well as a desktop computer to a low-crystal flat-screen TV, and then enjoy enhanced images. Such a connection is not always successful: for example, it can. However, there may be problems if the computer does not turn on the TV, connections via HDMI, if the wires are carefully added to the store, a variety of checks have been carried out. There are many reasons for incorrect cable operation, and the search for the correct problem must be carried out consistently.
What needs to be done if the TV does not connect to the laptop via HDMI? Video cards of all current players support such an HDMI connection on the TV, which is installed practically on the skin model. If you have followed all the rules for connecting the laptop, but there is still no image, then we connect the laptop to the TV, where we consistently check all the problems.
Checking the cable
Zhoden virib, navіt the most popular brand, is not insured against the factory cover, especially when folded by hand. When making a purchase, the picture quality and sound are checked, but some people on the TV do not check the specific sockets and connection sockets - at the very least, they will be recognized in their presence, but not all purchasers do. It often happens that the cable itself does not work I want to vikorist not for such a difficult time. It is necessary to connect this cable to another device if it is functioning normally - which means that the reason why the computer does not power up the TV remains the same. It is necessary to diagnose the TV to recognize similar signals.
Let's check the signal
Press the button on the remote control (RC) to select the external input option. Depending on the specific model, you need to select which button on the remote control of the TV you need to press: “source”, “input” or “HDMI” (LG, Sony or Samsung). After pressing, a menu with a report appears on the screen mix of active inputs. Select and confirm by pressing OK or Enter the most required input before you connected the cable to the laptop.
Working with a monitor
If the laptop does not drain the TV when several monitors are connected simultaneously, it is necessary to carry out additional adjustment. These simple manipulations can eliminate skin problems without special illumination:
- move the cursor to another place on the desktop;
- To display the menu you need to press the bear button to the right;
- We know the section “allowed the screen” - Windows 7, and if WindowsXP is installed, then “graphics characteristics”;
- Then you need to select the appropriate option to duplicate the screen.
If any laptop has a specific F4 key, if it is pressed simultaneously with the Fm button (right-handed under Crtl), then you can select the desired option for the current screen - this is how the computer begins to burn up.
Video card and drivers
Open the "Device Manager" of your laptop to check the driver versions of the installed video card. Outdated security software The main reason why the TV does not power up the laptop. In this case, you need to go to the manufacturer’s website, where you can purchase new firewood - the video card will be updated, and you can establish the necessary connection.
Possibly, the fault lies in the fact that the operating system was infected with viruses or that unauthorized programs were infiltrated. With the help of a powerful antivirus program (a program for protecting your computer) that detects all spies of any kind, carefully scan your computer and repeat the scan.
Some scammers recommend that you check the version for your Smart TV platform: sometimes the laptop does not connect via HDMI for this very reason. And, perhaps, the problem is no longer clear.
Malfunction of the connection port
Whatever rose we can mother mechanical damage or it will burn out when cutting the voltage, which is not uncommon in our electrical systems. It has been confirmed that we are happy to connect the HDMI device when connections between devices, it is recommended to connect the antenna cable for this hour.
There is another very rare reason why the TV does not use HDMI: it does not have additional life on the video card, and without it it will not work.
All details and connection options can be viewed in this video:
Algorithm for troubleshooting
If you know the reason why there is no image on the TV screen, then various damages have already been corrected. The axis looks like this, representing the visual order of the identification of malfunctions:
- Check the connection, visually check the current state of the skin connector and cables, so that the laptop stops powering the TV.
- Then the setup of the computer systems is checked: check which selection is selected in the menu items that indicate the connection of devices.
- Please update your video card drivers.
- In some situations, there is no harm in checking the settings of the video card itself.
- Re-scan your entire computer to get to Availability of free programs.
- Visually inspect the multimedia ports, their reference robot - a positive result will be immediately visible when connected to another device, for example.
If you have done everything possible, but from the laptop, as before, there is no signal to the TV, try other types of connection. Use the empirical method if you consistently use other connection methods. The process of comprehensive verification looks like this:
- Initially, the available connections and sockets are the same as the standard equipment we have installed;
- We connect TV and laptop in between;
- We connect the laptop to the TV using the HDMI cable;
- We turn on the TV, setting up its connection to the computer using an additional remote control;
- When the laptop is activated, as soon as the signal passes through, a picture similar to the one before the operating system is activated may be displayed on the TV screen;
- There is no signal - go to the “Device Manager” section, specify what types of connections are active;
- it is possible to install connection via VGA, you need to connect a similar cable to the devices;
- Then we carry out similar actions as from HDMI, only by pressing the “VGA” button on the remote control;
- as soon as you decided to make a connection for further help DVI, the cable is connected to the appropriate connectors, and a similar option is selected in the TV settings.
Since the technology has not yet responded to the work, the reason lies in the internal breakdown, which only a master can diagnose and put down. Of course, if you have knowledge in the field of electronic components of devices, you can try it.

When you connect the TV to an additional HDMI/DVI cable, the computer “downloads” the TV, but there is no image on the TV (HDMI mode is selected on the TV).
The current problem is mostly related to an unclear HDMI/DVI cable and it needs to be replaced.
Connecting a computer or laptop to a TV can be done in different ways:
- VGA cable chi D-Sud. This type of connector is available for almost all monitors, PCs and TVs. This is an analog connection, which is the best way to convey all the nuances of video files.
- DVI. More current option. Can be used with analogue or digital devices. I have my own subclasses.
- S-Video. Of course, you will have to buy an adapter.
- RCA or tulips. Connecting a laptop and TV in this way rarely happens.
- Scart. A popular method, as it is the case with current TV models.
- HDMI cable. A great option for connecting a computer.
Expanded causes of connection failure
If the TV does not turn on the laptop, but the connection is connected, the reasons may arise:
- The cable is connected incorrectly or is faulty.
- Setting up the monitor.
- The video card of the laptop or PC is incorrect.
- The parameters are not configured on the TV itself or any other market.
In the report we will discuss why the TV should not connect HDMI and other devices through it.
Stages of equipment verification
- First of all, we need to check the connection of the wires and the sockets.
- Next, you need to check the correctness of the computer settings.
- Then the drivers are updated and the video card is adjusted.
- Run anti-virus programs to scan for unwanted programs.
- Checking the port. It is recommended to connect to another device.
Checking the cable
As soon as the TV and connections to the PC stopped working, and until that moment everything was working properly, the video cable was either interrupted. The first option has more widths, so you can seal the adapter, just passing the positions. And the axis is different, because the optimal length for the HDMI cable is not so large that it lies on the base and rubs under your important foot.
TB adjustment
If the TV does not connect to the laptop via HDMI immediately after connecting the device, then for everything, select the wrong signal on the TV itself.
If there is no signal from the computer, then on the remote control of the TV you will find the “input”, “jerelo” or “Imput” button, or “HDMI” may be written on the LG TV. Go to the window that has opened, and there, near the list of active inputs, select the required one. Confirm this with “OK”.
If the device still does not connect after these operations, further diagnostics are carried out.
Adjusting the monitor
Having checked that the TV signal is correct, we move on to diagnosing the laptop or PC screen, or more precisely, to adjustment. This can be done by any professional with basic knowledge of your computer:
- Point the bear at any wide expanse of the screen and press the button on the right.
- From the list that appears, select “Display of screen” or “Graphic characteristics” under OS type.
- Select the required option to display the picture on the TV. The passport of the devices states the permissible separate building, please follow this.

Video card removal
Another reason why the connection of devices does not work is the incorrect functioning of the PC video card. In this case, the laptop does not load another device or display any other image.
To resolve this, you need to try installing new drivers, like those available in the global network for the skin model of the device. Sometimes it may be necessary to completely reinstall or replace the element.
In the article "" I gave the report instructions on how to do it, but if I tried to sign in the same way on another computer with two operating systems installed (Windows 7 and Windows 10), then I immediately found that when tazhenі retina s 'The tens logo appeared, and then the screen went dark and I couldn't do anything.

If you have a number of operating systems and they are located on different hard drives, then another hard drive that has not yet been configured with a video card should be physically connected for now. And after completely upgrading the first operating system, turn on the first hard drive (on my new Windows 10), and connect the other hard drive (on my new Windows 7). You can also try and not turn on the disks.
