Probably, no one needs to explain that laptops or ultrabooks, for all their capabilities, even when installing the most modern graphics accelerators, are not able to provide comfortable viewing of videos in the sense that they have a too small screen diagonal. Current TV panels have much larger screens. How to display the image from a laptop to a TV of any modern or outdated model will be discussed later. To do this, you will need basic skills in the field of connections and knowledge of the operating system of the computer and the TV (if, of course, it supports such functions).
Transferring an image from a laptop to a TV: basic aspects of connecting and broadcasting
The main problem of transmitting images from any computer or mobile device is the loss of quality and slowdown of video playback or broadcasting of the game, as well as the speed of opening the same photos.
Thus, initially the very question of how to output an image from a laptop to a TV consists precisely of solving problems of this kind. But here you have to think that the main problem is that, on the one hand, everything can work fine on the laptop, thanks to the same graphics accelerator that is not on the TV, on the other hand, the panel itself may not perceive the connection via the reason for the banal incompatibility of devices.
Connection options
As for combining a laptop or TV into one system, there are not so many options.
You can use either a wired connection based on the available inputs on the panel and outputs on a laptop like DVI or HDMI, or a wireless connection via Wi-Fi. The problem with cables is that they cannot be made too long (some experts indicate a length of no more than 15 meters, or even less). Wireless communication also has its limitations related to the range of the router (router or ADSL modem), which according to the wilted characteristics is about three hundred meters in direct visibility, but is limited to only a hundred, and even not always (some TP-Link routers support and even less).
How to output image from laptop to TV via HDMI?
Cable connection of the laptop to the television panel is the easiest. However, in this case, several nuances should be taken into account.
Firstly, there will be no sound with a direct connection, since the HDMI interface is not designed for this initially. Therefore, you will have to go into the Windows sound settings with the image on the TV screen and select the HDMI sound driver, and not the one that is installed by default in the system (like High Definition Audio).
Please note that at the same time, two simultaneous connections on the described interface are not supported. That is, if you have a television set-top box or a home theater, you will have to turn them off.
Further (on the example of Windows 10) everything is simple. Click on the notification button in the system tray and select the screen duplication tile . After that, use the desired mode.
Wireless connection
Now let's see how to display an image from a laptop to a TV via WiFi. In principle, the actions in practice are almost the same, but in this case, the main role is played by the synchronization of the panel with the laptop (provided that the TV itself has a built-in wireless module). Despite the fact that there is such a tool in Windows systems themselves, Miracast, Wi-Fi Direct or Intel WiDi cannot be dispensed with.
If there is such an opportunity, there is no need to invent anything in solving the problem of how to output an image from a laptop to a TV. Launch the applet on the TV with synchronization enabled on the laptop and wait until the connected device is detected. In general, the problem of how to output an image from a laptop to a TV, using modern technology, is solved quite simply. But in some cases there may be delays, which, most likely, are associated either with the connection or with the compatibility of the equipment.
What's better?
If we summarize in deciding how to display an image from a laptop on a TV, we have to admit that modern routers are not able to provide the necessary data transfer speed, but wired connections work much better. Problems with HDMI are solved in the most elementary way of choosing the appropriate playback device. There are no such problems with DVI, but connecting via several tulip-type plugs (as many users or companies that provide online TV viewing services advise, it is better not to use it at all - the quality is lower and the signal is not the same).
Thus, it is not difficult to conclude that the wired connection of a laptop or a stationary computer terminal to a modern television panel at the moment remains so relevant that no wireless technology will surpass it (especially since such communication can cause errors and malfunctions of a program nature).
