Start by diagnosing the root cause of the delay, which could be related to network bandwidth, hardware limitations, or software inefficiencies. Prioritize a stable and high-speed internet connection, ideally with a wired Ethernet setup, to reduce fluctuations in bandwidth that can cause lag. Optimize video conferencing settings by lowering the resolution or disabling non-essential features like screen sharing or background effects, which can strain the connection. Ensure that all participants are using updated software and hardware, as older devices can introduce latency.
