Quality profiles and bandwidth
How Ultra-Low, Eco, Balanced, Auto, Performance and Custom trade picture quality for data, what they measured, and how to stay usable on a weak link.

The profiles
Low data use is the point of Silux Connect. Every profile sends only the parts of the screen that change, and an idle screen sends nothing at all. These are the median rates measured while the screen was changing:
| Profile | Measured median | Label in the app | Best for |
|---|---|---|---|
| Ultra-Low | 86 kbps | ~150 kbps · weakest links | Satellite, roaming, 2G/3G, congested hotel Wi-Fi. Starts at a third of the resolution and sharpens text in the background. |
| Eco | 218 kbps | 150–300 kbps · sharp text | Office work on modest mobile data: crisp text, fewer frames. |
| Balanced | 966 kbps | 500 kbps – 1 Mbps | Normal broadband. |
| Auto (adaptive) | 1,383 kbps | Adapts every second | The default: steps down when your link struggles and back up when it recovers. |
| Performance | 2,376 kbps | 2–5 Mbps · silky smooth | Fast links, video, design work. |
| Custom… | Your choice | Frame rate, colours, picture scale | Fine control: e.g. 5 fps used ~350 kbps in testing. |
Good to know: Figures are medians from our end-to-end tests; real use depends on what is on screen. On a 150 kbps link the picture responded to a click in about half a second and stayed pixel-exact after sharpening.
Changing the profile
- Website: the quality menu in the session toolbar. Custom… reveals Frames per second (5, 10, 15, 20, 30, 60), Colour depth (Colours: low, medium, high, full) and Picture scale (Full, Half, Third resolution).
- App: the Bandwidth profile button; Custom… → Apply. Set the starting profile in Settings → Default quality profile.
Saving even more data
- Options… → Hide wallpaper (less data).
- Lower the Remote resolution on the picture bar — restored when the session ends.
- Actions… → Show only the window in front (less data).
- Show one monitor rather than All monitors (uses more data).
- Leave Audio, Camera and recording off unless you need them.
- For command-line work use Terminal Sync — text only, a tiny fraction of a picture stream.
Reading the connection stats
The session header shows resolution, fps and kbps. Options… → Show connection quality adds delay and relay round-trip time, plus the active profile. A Direct badge means the picture goes peer-to-peer, which usually cuts delay.
