A question that comes up a lot: what upload bandwidth do I need to stream my desktop or a game smoothly? Here are practical reference numbers and how to pick a tool by scenario.
Bandwidth reference (upstream)
| Quality | Upload needed |
|---|---|
| 1080p 60fps | 12–20 Mbps |
| 4K 60fps | 40–60 Mbps |
| 4K 144fps | 80–120 Mbps |
The bitrate scales roughly with megapixels × fps, plus a factor for motion-heavy content (gaming ~1.4×, design/true-color ~1.6×).
Pick by scenario
- Office / remote help — stability over everything; 30–60 ms latency is fine.
- Game streaming — aim for <20 ms (wired or 5 GHz). In public reviews, UU Remote hits ~10.2 ms end-to-end and offers 4K/144 on the free tier; the wireless second-screen feature is handy for a laptop as a second monitor.
- Design / video — you want 4:4:4 true color (uncompressed), so prioritize a high custom bitrate.
- Enterprise / server room — you need remote power-on + out-of-band control. Sunlogin's enterprise/信创 stack does ~7 ms at 4K@144 and supports remote boot hardware; see the Sunlogin vs ToDesk comparison.
A tiny calculator
I made a small open tool that estimates the upload you need and suggests a setup by scenario (pure front-end, runs on GitHub Pages):

If a session is laggy, first measure: lag appears when host upload <10 Mbps or client download <15 Mbps. Lower the resolution/fps, pick a nearer relay node, and go wired.
