Is Starlink suitable for watching 4K streaming video and making video calls?

No problem, I'll explain this to you based on my experience, so you'll understand it immediately.

The simple and direct answer is: In most cases, it's absolutely fine. Whether it's watching 4K movies or holding video conferences, Starlink can handle it, and the experience is quite good.

However, there are some details, which I'll discuss in two parts, and then you'll get it.

1. Watching 4K Streaming Video (e.g., Ultra HD on Netflix, YouTube)

This is a piece of cake for Starlink.

You can imagine internet speed as a highway. To smoothly watch 4K video, you'd need a highway about 3-4 lanes wide (which is roughly 25Mbps).

Starlink typically provides a highway that's 10 lanes wide or even wider (100-200Mbps speeds are common). So, when you're watching 4K video, there's more than enough bandwidth for the data traffic, making it very smooth.

Furthermore, watching videos has an advantage: the player "preloads" (caches) content, much like having goods delivered to a warehouse at your doorstep in advance. Even if the network occasionally experiences a bump, such as a brief one-second stutter during a satellite handover or bad weather, the player will immediately retrieve content from the "warehouse," and you'll barely notice any impact.

So the conclusion is: Feel free to watch 4K with Starlink; the experience is largely indistinguishable from using urban fiber optic broadband.

2. Making Video Calls (e.g., WeChat Video, Zoom, Teams meetings)

This demands a bit more than video streaming, but Starlink is equally capable.

The key to video calls isn't just "is the road wide enough" (internet speed), but more importantly, "is the response fast enough," which we call latency (Ping value).

Imagine making a phone call: if it takes several seconds to hear the other person after they speak, the conversation becomes impossible. Video calls are similar; low latency means that video and audio are transmitted very promptly, making interactions natural.

With traditional satellite internet, satellites are too far from Earth, so signals travel a long distance back and forth, resulting in very high latency. Video conferencing becomes a torment; you say something, and the other person has to wait a long time to respond.

However, Starlink's satellites are very close to Earth (in Low Earth Orbit), significantly shortening the signal's round trip. Therefore, its latency is very low, typically between 20-50 milliseconds. This level is comparable to many terrestrial networks (like 4G/5G or regular broadband) and is sufficient to ensure smooth video calls, avoiding that awkward "I spoke, and you took ages to respond" situation.

However, there's a small "but" here:

Because your antenna constantly needs to switch connections between satellites in the sky, occasionally, during that brief moment of switching, the network might experience a momentary pause of a few tenths of a second.

• For video streaming: No impact, thanks to caching.
• For video calls: You might encounter the screen momentarily "freezing" for about a second once or twice during a multi-hour meeting, then immediately resuming normal operation.

This situation doesn't happen often, but it can occur. Especially during severe weather (like heavy rain or snow), the signal can be affected, increasing the likelihood of such momentary stutters.

In Summary

Using Starlink as your primary home internet to meet daily entertainment and work needs is entirely feasible.

• Watching 4K video? Go ahead, the experience is excellent.
• Holding video conferences? It's very smooth 99% of the time. Unless you're performing ultra-high-precision remote surgery where not even a second of interruption is tolerable, for everyday work meetings and video chats with family and friends, the occasional tiny momentary stutter can largely be ignored.

Overall, for those living in remote areas without fiber optic or stable 4G/5G networks, Starlink is truly a "savior." It has turned the previously unimaginable high-quality internet life into a reality.
