| Delay | Yes (30-100 ms) | Minimum |
| Background work | No (screen active) | Yes (can be collapsed) |
| Quality | Depends on the signal | Original |
Why is DLNA better for 4K video?
The DLNA protocol transmits an already encoded file directly, without requiring real-time video stream re-encoding, which reduces the load on the processor and Wi-Fi module.
