Preliminary operation
To connect PC to HDMI TV, the first step you must take is to verify that both the computer you intend to use and the TV in your possession are equipped with an HDMI port.
To verify this, just take a look at the front or back of the PC case and on the sides of the laptop body looking for a small black input labeled, precisely, as HDMI. To verify that your TV also supports HDMI, try to take a look at the back and verify that among the various inputs available there is also one (or more) labeled with the inscription HDMI.
Adapters and cables
If there are no HDMI ports available on your computer or TV, you can still buy a HDMI adapter. You can find various and at very low prices on Amazon or in any trusted electronics store.
In particular, instead of the HDMI port you may be dealing with a type port Thunderbolt in USB-C format (like that of the latest Apple MacBooks), Mini HDMI (type C connector) or Micro HDMI (type D connector). In these cases, to remedy, it is sufficient to combine the classic HDMI cable with a adapter or hub USB-C to HDMI, HDMI to Mini-HDMI or HDMI to Micro-HDMI.
If, on the other hand, you want to know how to connect PC VGA to HDMI TV because you have an old computer without an HDMI port, you can buy a VGA to HDMI adapter, however, know the output quality will not be the best (as the maximum resolution supported by the VGA output is 640 × 480 pixels, so not even Full HD).
Once you have ascertained the fact that your devices support the interface in question or that you can in any case cope with the absence of the HDMI input using a special adapter, in order to make the connection between the computer and the TV you obviously need a HDMI cable.
Again, you can turn to Amazon or you can go to an electronics store and make the purchase of the cable in person. The price of an HDMI cable is quite low and between one cable and another it can vary depending on the length of the same. If you need to stream 4K resolution streams at the highest quality and refresh rate, be sure to buy a cable HDMI 2.0.
Connection and configuration
After finding the cable to connect PC to HDMI TV, the operations you need to carry out to complete your "mission" are very simple. All you have to do is open the package in which the cable is contained, unroll the cable and connect one end to the HDMI port of the TV and another to the HDMI port of the computer.
After connecting PC to HDMI cable TV you need to tune to the channel of the video signal coming from the computer. To do this, take the TV remote control, press the key for choosing the video source (Eg source) or access the menu of configuration and management of the device and to that relating to sources and then select the port to which you connected the computer (for example HDMI1). Once this is done, you can choose whether to use the TV screen as a duplicate of the computer desktop (so you can reproduce what happens on the PC screen in real time) or whether to configure it as a desktop extension and use it as a secondary monitor. You will find everything explained in detail below.
Please note: In the event that after having connected PC to HDMI TV following my instructions there should be some display problem or if no connection has been established between computer and TV, I suggest you repeat the procedure from the beginning (sometimes it does not work at first shot!) and make sure that the cable is well connected to the HDMI input.
