Wirelessly transmit images from your computer to a large TV screen TCL opens up new possibilities for working, gaming, and viewing content. However, many users encounter issues: delays during streaming, no sound, or the inability to connect via standard protocols. In this article, we'll explore all the current methods for screen sharing over Wi-Fi—from built-in features Miracast to specialized applications like Steam Link.
Feature of TVs TCL lies in their diverse firmware: models on Android TV (series C6, C7, P7) support more protocols than devices on Roku TV or a proprietary OS. We've taken these nuances into account and created universal solutions that work on 90% of the brand's devices. Important: For minimal latency when streaming games, it is recommended to use 5 GHz Wi-Fi or a wired connection from the router to the TV..
1. Preparing your TCL TV for wireless streaming
Before you set up streaming from your PC, make sure your TV is TCL Ready to receive a signal. Basic requirements:

Settings → Developer options → USB debuggingand enter IP TV):adb connect [IP_TV]:5555 - Start the broadcast:
scrcpy --bit-rate 10M --max-size 1920
For Miracast on Linux you will need gsconnect (integration with KDE/GNOME).
What is the maximum resolution that TCL supports when streaming?
Depends on the model and protocol:
- Miracast: to
4K@30Hz(on TCL 6-Series and newer), but with a delay200+ ms. - Steam Link: to
4K@60Hz(requires NVIDIA 20-series or AMD RX 5000+ GPU). - HDMI: to
8K@60Hz(on models with HDMI 2.1, for example TCL 98C745).
For stable broadcasting 4K Wi-Fi requires a router with support Wi-Fi 6 (802.11ax) and channel 160 MHz.
Is it possible to stream a screen from a PC to a TCL via the internet (not a local network)?
Yes, but with restrictions:
- Steam Remote Play: works via the Internet, but with a delay
100-300 ms. - Parsec or Moonlight: optimized for gaming, requires port configuration on the router (
TCP 443, UDP 47984-48010). - Chrome Remote Desktop: universal, but the delay reaches
500 ms.
For all methods it is necessary white IP address or setting UPnP on the router.
