Wi-Fi Display dongles and associated latencies table

I've written about the Wi-Fi Certified Miracast program (and related Wi-Fi Display specification) before, so I'll spare you the intro. But what you may not know is that for about two years now, I've been testing and collecting wireless display dongles, an esoteric hobby for sure. Per request, I put together a chart of my devices and associated latency observations and am sharing that today.

When I refer to latency, I'm talking about the time it takes for an image on a source device (e.g. a Surface Pro) to appear on the target device (e.g. TV).

My test parameters are as follows:

  • Source device: Surface Pro
  • Target device: LG 47LG70
  • Distance between devices: 3ft
  • Resolution: 1080p @ 30fps

Testing involves running a simple program that displays a counter and loops through a movie trailer that covers over 90% of the screen to exercise motion compensation algorithms and observe quality and latency hits, if present. I then take a picture with a DSLR of both the source and target (in the same frame) and subtract the counts to determine latency.

🔧 Xbox One latency was measured with different hardware (Surface 3), so its number isn't directly comparable to the other devices. This will be fixed when all devices are re-tested with new hardware.
