FAQ: Frequently Asked Questions

Is it possible to connect a Windows tablet to a TV without Wi-Fi?

Yes, there are three ways:

1. Through HDMI-cable with adapter (for example, USB-C to HDMI).
2. Through USB-Wi-Fi adapter, connected to the TV (if it has a port USB).
3. Through Ethernet (if both devices support DLNA via cable).

However, without Wi-Fi, you lose the ability to stream your screen in real time - only media files.

Why is there no sound on the TV when connected via Miracast?
Reasons and solutions:
• 🔇 The wrong audio output is selected on the tablet: go to Settings → System → Sound and select the output device (should be the name of your TV).
• 🔊 The sound is muted on the TV HDMI-mode: check the settings Sound → Sound Source → TV Speaker.
• 🎵 Audio format not supported: Please re-encode the audio to AAC or MP3 (for example, through VLC).
How to reduce lag during broadcasting?

The delay occurs due to:

• 📶 Weak Wi-Fi signal: Connect to the network 5 GHz or use Wi-Fi Direct.
• 🖥️ Tablet resource shortage: Close background programs through Task Manager.
• 📺 TV limitations: on older models Samsung lags can only be eliminated by lowering the resolution to 720p.

For games or videos it is better to use HDMI- connection - the delay will be minimal (10–50 ms).

Is it possible to broadcast a screen to a TV via the Internet (not via a local network)?

Technically yes, but with some caveats:

• 🌍 Through TeamViewer or AnyDesk: high latency (1-3 seconds), suitable for presentations only.
• ☁️ Through cloud services (for example, Rainway): requires a powerful Internet connection (from 50 Mbps).
• 🚫 Miracast And DLNA work only in a local network.

For stable broadcasting over the Internet, it is better to use specialized devices, for example, NVIDIA Shield with function GeForce NOW.

What is the maximum resolution supported for wireless streaming?

Resolution depends on technology:

Technology	Max. permission	Max frame rate
Miracast (Wi-Fi 5)	1920×1080	60 Hz
Wi-Fi Direct	1280×720	30 Hz
DLNA	3840×2160 (video only)	24 Hz
ApowerMirror (premium)	2560×1440	60 Hz

For 4K required HDMI 2.0 or Wi-Fi 6 (on new TVs and tablets).
