Network requirements and pre-requisites
The foundation of a successful broadcast is a stable local network. For example, to transmit a high-definition video stream 1920×1080 or 4K, high bandwidth is required. Make sure your router supports the standard. Wi-Fi 5 (802.11ac) or newer, and also operates in the 5 GHz band.
It's critical that the computer and TV are on the same subnet. This means both devices must be connected to the same router. If you're using a mesh network, make sure they don't isolate clients from each other using the AP Isolation feature.
⚠️ Note: If your router is sharing a guest network, devices on it may be isolated from the main network. For proper streaming, connect your PC and TV to the main Wi-Fi network, not the guest network.
Check the driver version of the wireless adapter on your computer. Outdated software may not support the protocols. Miracast or it may work with errors.

| Connection type | Wi-Fi Direct / Local Area Network | Local area network | Local area network |
| Delay | Low | Average | None (buffering) |
| Quality | Depends on the signal | High (adaptive) | Original file |
| Sound | It is transmitted | It is transmitted | It is transmitted |
The advantage of the Chrome method is the ability to stream the contents of one tab while continuing to work with other windows on the computer. This method is also often better optimized for streaming videos from YouTube or Netflix, providing better image quality than simple screen mirroring.
Why might Chromecast work better than Miracast?
Chromecast technology often uses hardware decoding on the TV side, while Miracast relies on encoding the PC's video output stream, which puts additional strain on the computer's processor.

It's recommended to force the network to switch to 5 GHz mode if your devices support it. This range is less polluted by household appliances and neighboring networks. It's also worth setting the channel width. 80 MHz for maximum throughput, although in multi-apartment buildings with a large number of networks it is sometimes more efficient to choose 40 MHz.
⚠️ Note: Router interfaces vary between manufacturers (Keenetic, TP-Link, ASUS). Specific menu item names may change depending on the firmware version. Please consult the official documentation for your device.
