Question About Meta Quest 3 Display Latency and Timing Accuracy

Hello,

I am a graduate student currently planning a research study that combines EEG recording with virtual reality, and I am considering using either the Meta Quest 3 or 3S headset. Because EEG analyses require precise synchronization between stimulus presentation and neural recordings, I am trying to better understand the timing characteristics of these devices.

I was wondering whether there is a delay between:

• A visual stimulus being rendered or presented by a program running on a computer, and
• The stimulus actually appearing on the display inside the Quest headset.

If such a delay exists, I would greatly appreciate any information regarding:

• The typical end-to-end display latency (measurable delay) for Quest 3/3S.
• Whether the latency differs between wired and wireless PC connections.
• The expected variability (jitter) in presentation timing.
• Any technical documentation, specifications, or user experiences related to display latency and timing accuracy that may be useful for research applications.

The goal of this is to ensure accurate synchronization between EEG recordings and visual stimulus presentation, so any information regarding timing characteristics would be extremely valuable. 

I initially planned to contact Meta's technical support team directly, but I was unable to find an email address or another way to submit a technical inquiry of this kind, so I posted my question here instead. If anyone knows the appropriate channel for contacting Meta's technical support or engineering team about these questions, please let me know.

I would greatly appreciate the information, all your answers and times.
