I noticed that very often there are questions that arise when setting up a DLNA server on a computer to watch movies on a TV that supports DLNA.
Namely, questions about the problem when the TV does not see the DLNA server created on the computer. And accordingly, does not see the files (movies, photos, music) that are on the computer.
There can be a lot of reasons why such a problem may appear. But, most likely, this is due to the fact that the antivirus or firewall installed on your computer (probably also the standard Windows firewall), blocks the connection. They prevent your TV from seeing movies that are on the computer.
Here are the actual instructions for setting up DLNA:
If you did everything according to the instructions, but the TV did not see your computer, then for starters:
If everything is fine on the above points, then you need to try disabling the antivirus. I know for sure that Avast likes to block such connections. But, other antiviruses are no exception. Also, you need to try disabling the firewall if it is installed on your computer. AND .
You don't need to completely uninstall your antivirus. In almost every antivirus, it is possible to completely, temporarily disable protection.
This can usually be done by right-clicking on the antivirus icon in the notification bar and selecting something like Suspend Protection.
This is how it is done in Kaspersky Internet Security:
Perhaps the antivirus will still ask you for how long to disable protection, or ask you to confirm the shutdown. Let me remind you that I showed the example of Kaspersky Internet Security. If you have a different antivirus, then things may be a little different.
After disabling the protection, go to the desired menu on the TV (on LG, this is for example Smart Share) and see if your TV has seen the contents of the computer. You can also turn the TV off and on.
I'm sure everything should work out. If everything worked, and the folders or files that are on the laptop were displayed on the TV, then the problem is really in the antivirus.
Turning off the antivirus every time is also not an option. Therefore, you need to try adding your connection to the antivirus exclusions. Or, it may block the program itself, such as "Home Media Server (UPnP, DLNA, HTTP)". In this case, the program must be added to the exceptions. On each antivirus, this is done differently. Look for something like: application control, program activity management, network activity, firewall.
As for the problems in Wi-Fi routers, through which the devices are connected, then there are their own chips. According to the idea, no settings in the routers themselves need to be done. But, I saw advice in the comments that you can try to uncheck the "Prohibit multicast" item on the tab where Wi-Fi settings are set.
Here is a comment:
I have not seen such an item, for example, in Tp-Link routers. If there is such an item in the settings of your router, then you can try it. Best wishes!

The TV does not see movies that are on the computer (laptop) after starting the DLNA server updated: August 23, 2015 by: admin
Often, if HDMI does not work on the TV, there are connection problems. Causes:
To avoid problems with device connections, learn how to do it correctly. Follow instructions:
Given the complexity software settings not everyone is able to complete the task on their own. It is better to turn to specialists so that you do not have to correct the mistakes of an inexperienced user.
If, after checking the settings, the TV connected to the laptop suddenly stops working, then two options are possible:
The first problem is more likely. The user could accidentally hit the cord, disrupting the stability of the connection, and the image stopped being fed to the TV screen.
A broken wire is rare. Usually the product wears out naturally (temporary wear).
The entrance may also be broken. Replacement is a simple procedure for a specialist. An inexperienced user runs the risk of damaging adjacent sockets, or the board where the port is connected.
Modern game consoles (PS3, X-box) are also connected via HDMI. Despite the peculiarities of the devices, malfunctions and root causes are of a similar nature. If the port or wire is damaged, it will not be possible to start the set-top box. The PC or TV writes: “no signal”, although in fact everything was connected correctly.
You need to set up a TV and a PC or laptop. When the equipment does not contact, there is no synchronization, probably the signal source is incorrectly selected:
After the change, everything should work.
If you are convinced that the signal from the television equipment is received and transmitted normally, but the image does not appear, pay attention to the computer:
Today, any user using an HDMI cable can, as well as a desktop computer to a flat-screen LCD TV, and then enjoy an expanded image. Such a connection is not always successful: for example, it can. But there are times when the computer does not see a TV connected via HDMI at all, although you just purchased the wire in a store where a comprehensive check was carried out. There are many reasons for the incorrect operation of the cable, and the search for the true problem must be done consistently.
What should I do if the TV does not see the laptop via HDMI? Video cards of all modern products support this connection: HDMI on the TV is installed on almost every model. If the laptop was connected according to all the rules, but there is still no image, then we connect the laptop to the TV, while sequentially checking all possible problems.
Not a single product, even the most reliable brand, is immune from factory defects, especially when manually assembled. When buying, the quality of the image and sound are checked, but they never check specific connectors and connection jacks on the TV - at best, they make sure that they are available, and even then not all buyers. It often happens that cable does not work although it has not been used for very long. It is necessary to connect the same cable, but to another device, if it functions normally, then the reason that the computer does not see the TV lies in the latter. It is necessary to diagnose the TV for recognition of similar signals.
On the remote control remote control, press the button to select the external input option. It depends on the specific product model which button on the TV remote control you need to press: “source” (source), “input” (input) or “HDMI” (LG, Sony or Samsung). After clicking on the screen, a menu appears with detailed list of active inputs. We select and confirm, by pressing OK or Enter, exactly the desired input, into which the cable coming from the laptop was previously connected.
If the laptop does not see the TV when multiple monitors are connected at the same time, then it is necessary to carry out additional settings . These simple manipulations can be performed by each user without special education:
Any laptop has a specific F4 key, if you press it together with the Fm button (located to the right of Crtl) repeatedly, you can select the desired option for the external screen - this is how the computer starts to see TV.
Open the "Device Manager" of your laptop to check the driver versions of the installed video card. Legacy Software is the main reason that the TV does not see the laptop. In this case, you need to go to the manufacturer's website, where you can download new "firewood" - the video card will be updated, you will be able to establish the required connection.
Perhaps the fault lies in the fact that the operating system was infected with viruses or there was an unauthorized entry of malware. With the help of a powerful antivirus program (computer protection program) that can find all spies of any level, we carefully scan your computer and reconnect.
Some experts strongly advise you to check the version for your Smart TV platform: sometimes a laptop does not connect via HDMI for this very reason. and perhaps the problem will go away.
Any connector can be mechanical damage or burn out during a power surge, which are not uncommon in our electrical networks. Experienced craftsmen advise connecting the HDMI wire when offline devices, even the antenna cable is recommended to be disconnected for this time.
There is also such a very rare reason why the TV does not see HDMI: it simply does not have additional power on the video card, and without this the connection will not work.
You can see all the details and connection options using this video:
If you know the reason why there is no image on the TV screen, then the elimination of various violations is already a solvable task. Here is an approximate procedure for troubleshooting detected problems:
If you've done your best, but your laptop still has no signal to your TV, try other types of connections. Use a rule of thumb where all existing connection methods are consistently used. The due diligence process will look like this:
If the equipment has not started working together, the reason lies in an internal breakdown that only the master can diagnose and fix. Of course, if you have knowledge in the field of electronic stuffing of devices, you can try.
Connecting a computer or laptop to a TV can occur in different ways:
If the TV does not see the laptop, and the connection is made, then the reasons may be as follows:
Let's take a closer look at why the TV does not see HDMI and the second device through it.
If the TV connected to the PC suddenly stopped working, and up to this point everything was set up properly, it means that the cable has come off or it has been interrupted. The first option is more common, as you can hook the adapter just by passing by. But the second one is less common, since the optimal length of the HDMI cable is not so long as to lie on the floor and fall under someone's heavy leg.
When the TV does not see the laptop via HDMI immediately after connecting the equipment, it is most likely that the signal source selection on the TV itself is incorrect.
If there is no signal from the computer, then on the TV remote control you should find the “input”, “source” or “Imput” button, it may be immediately written “HDMI” on the TV from LG. Go to the window that opens and there, in the list of active inputs, select the one you need. Confirm the action by clicking on "OK".
If the equipment still does not connect after the performed operations, we carry out diagnostics further.
After making sure that the signal from the TV is on the right path, we proceed to the diagnostics of the laptop or PC screen, or rather, to the settings. Any user with basic knowledge of their computer can conduct them:
Everything is easier to do on a laptop. Hold down the "Fm" and F4 buttons at the same time, hold until the best option is selected. After that, the laptop will connect to the TV correctly and the error that there is no image will go away.
Another reason why the device connection does not work is the incorrect functioning of the PC video card. In this case, the laptop does not see another device or does not display an image on it.
To eliminate it, you need to try to install new drivers that are on the global network for each device model. Sometimes it may be necessary to completely reinstall or replace an item.
We have prepared detailed instructions for users who are wondering why HDMI does not work on a laptop. Use a few solutions below to fix the issue.
You should note that HDMI does not work on a laptop, mainly due to faulty drivers or settings. However, you should make sure that the problem is not with the HDMI port or cable.
Before following these steps, try simply unplugging the cable from your TV or projector, and plugging it back into the HDMI port.
Also check the connection with another HDMI cable as this may be the problem. If HDMI is still not working on the laptop, then use the following solutions.
1. Click Start and click the Settings icon in the bottom left corner.
3. Select Display from the menu on the left, and check if the TV is set as a second monitor.
If the TV is not detected, follow these steps:
1. Simultaneously press Win + P (Windows logo key and P key).
2. Select Recurring from the pop-up menu on the right side.
3. If "Repeated" doesn't work, try switching to "Expand".
After that, you will see the TV in the display output settings.
The problem with why HDMI does not work on a laptop may lie in the video Windows drivers. You can go to Device Manager to check the status of the display drivers. Under the Display Adapters category, you'll see Microsoft Basic Display Adapter, Intel HD Graphics, Nvidia Geforce, or others, depending on the graphics card you're using on your laptop.
Follow the steps below to update video drivers using Device Manager.
1. Right-click on the name of the display device and select "Update Drivers".
2. Select "Auto search" to update software. Windows will automatically search for and install a new driver.
Please note that Windows does not always provide the latest drivers. In such a case, you will have to download new drivers manually.
You can download and install drivers from the manufacturer's official website. Find out the exact model of your laptop, operating system version, then go to the video card manufacturer's website and download video drivers to your computer.
