Why do I experience delay on 4k via AirPlay

The Neo runs the AirServer application to facilitate wireless sharing. This application supports up to 4K wireless sharing in default mode. However, the Neo main chip does not support hardware decoding at 4K while using the AirPlay protocol with Apple Mac products. In that case, the Neo will switch to software decoding – which is much slower – and will cause a significant lag (10-30s).

We therefore advise to change the default AirServer setting (accessed via the Settings menu, Functionality tab, AirServer settings button) ‘Limit Mirroring Resolution to reduce bandwidth’ to ON. This will limited the sharing resolution for all sharing protocols and devices (so also Windows and Android devices) to 1080p. Unfortunately, Neo hardware does not support 4K AirPlay sharing without a delay.
