The four feeds stay sharp on my laptop, with steady playback and clear audio. HD loaded quickly, and I did not notice any buffering.

I tuned in for the morning news while keeping an eye on traffic and the weather. The split-screen setup made it easy to follow several live scenes without switching channels.

I kept this quad view open during a rainy evening abroad, switching between the traffic angle and the skyline while waiting for a documentary to start. It is less polished than cable, but the live split-screen stayed useful and surprisingly steady on a slow connection.
