Importantly, on models with MIUI 14+, there is a feature called “Fast projection”, which automatically determines the best way to connect to external screens. Next, we will analyze each option in detail, taking into account the features of the firmware and hardware limitations.

Connection via HDMI: a reliable wired method

If your projector is equipped with an HDMI port, this is the most stable way to transfer images without delay. Xiaomi will require a USB-C → HDMI adapter (or Micro-USB → HDMI for older models).
