| 4K UHD video | Ultra HD | 25 Mbps | High |
| Cloud gaming | 1080p / 4K | 35-50 Mbps | Critical (Low Latency) |
Software Updates and Security
Like any computer, a modern TV runs on an operating system that requires regular updates. Firmware contains bug fixes, security improvements, and new features. Manufacturers release updates through Wi-Fiso that users can easily keep their device up to date.
Ignoring updates can lead to unstable applications, compatibility issues with new video formats, or security vulnerabilities. Automatic update The easiest way to avoid these problems is via the internet. The TV will download and install the package automatically, often even when it's turned off (in standby mode).

Technical requirements and router selection
For a TV to function fully, simply having a Wi-Fi router isn't enough. Its technical specifications are also important. Most modern TVs support the following standards: Wi-Fi 5 (802.11ac) And Wi-Fi 6 (802.11ax)Using an older router with a 2.4 GHz band can become a bottleneck for 4K content.
The router's location also plays a role. Walls, especially load-bearing ones, and household appliances create interference. For stable operation Smart TV It is recommended to place the router in a direct line of sight or use Mesh systems to cover larger areas. Wireless signal must be sure of the location where the TV will be installed.
Dual-band routers
If your router broadcasts two networks (2.4 GHz and 5 GHz), connect your TV to the 5 GHz band. This will ensure faster speeds and less interference from neighboring networks and microwave ovens.
If the distance to the router is large and it is impossible to lay a wired connection (LAN), you can use Powerline adaptersThey transmit internet through electrical wiring, providing stability similar to cable, which is often better than a weak Wi-Fi signal.
- 📡 Support for the 802.11ac (Wi-Fi 5) standard or later.
- 📶 Operates in the 5 GHz band to reduce interference.
- 🏠 Using Mesh systems for large apartments.
- 🔌 Alternative: Powerline adapters for weak signals.
