Sometimes we want to see the content on our mobile phone or computer on a larger screen, but it is not always easy.

Next, we will review the main characteristics of these devices so that you are clear about what criteria to follow when choosing one model or another. The maximum range. The first thing we must be clear about is the distance at which we are going to have each of the wireless HDMI kits, since not all of them offer the same maximum range. In addition, it is important to know both the maximum distance and whether they are capable of transmitting the signal through physical obstacles such as walls, since some models require direct vision between both connectors for them to work correctly. The resolution and refresh rate supported. Generally, the wireless HDMI kits that we will find in stores will offer Full HD or 4K resolution. Depending on the use we want to give it, it is advisable to choose one or the other. For example, if your idea is to work or use some programs from the couch, a Full HD resolution will be enough. On the other hand, if you want to play multimedia content, the resolution should be 4K (as long as the television is compatible). The same goes for the refresh rate. If you are going to watch movies and series or use some applications, a rate of 60 Hz will be enough. But if you are looking for a much smoother experience because you are going to play video games, it is recommended that the rate reach 120 Hz. The latency. Latency is the time it takes for the image to be played from a device where we have the main HDMI connector installed until it reaches the screen where we have the second connector. And since we are talking about wireless devices, it is practically inevitable that we will encounter some latency. If you are going to watch a movie, latency will not have as big an impact on having a good experience. On the other hand, if you are going to play video games, especially if they are competitive, it is advisable that the wireless HDMI connector have a very low latency. The frequency band. The frequency band is the channel through which data will be sent between both HDMI connectors. Normally we will find 5 GHz and 60 GHz frequencies, and each of them has its advantages and disadvantages: 5 GHz: is the most common, offers good speed and is capable of passing through physical objects such as walls. 60 GHz: In models that work at 60 GHz, the speed is usually higher, but they require direct vision between transmitter and receiver, so they normally do not pass through walls. Connectivity. Some wireless HDMI kits come with a single HDMI port to function, while others are more complete and offer the possibility of connecting them to devices through other ports, USB-C being the most common. It is important to be clear about what devices we are going to use. If it is a laptop, it is possible that (almost) any model will work for you. On the other hand, if you are going to connect a mobile phone, you will need it to have a USB-C port or an adapter. Transmitters and receivers. These types of devices generally come with a transmitter and a receiver, although several may come. In any case, it must be taken into account that: Transmitters capture the signal from the source device and send it to the … Read more
