Video Signal Input Lag Tester
Many people who tested our CES Wireless VR demo asked our how we measured latency.
We used the Leo Bodnar Electronics Lag Tester. The product generates a test patern output via HDMI. The unit is then held up to the display and uses a photo sensor to measure the latency. The measured latency is then output as a number on the display. You can order the product for around $100 directly from Leo Bodnar in the UK.
