A reliable IPTV service for four screens needs strong servers, enough home internet speed, and the right player settings. SubTV IP pairs 99.9% uptime and an anti-freeze server cluster with 4K HEVC streams.
Your part is a fast connection, Cloudflare DNS (1.1.1.1), and a 5,000 ms buffer.
What "Reliable for 4 Screens" Really Means
IPTV means TV delivered over the internet instead of a cable or dish. Each screen that plays a stream pulls its own flow of data. So four screens at once means four streams running at the same time.
Smooth playback on every screen depends on three things working together:
- The service's servers: they must stay online and send data steadily.
- Your home network: it must have enough speed for all four streams.
- Your devices and apps: they must be set up to handle small drops in speed.
If any one of these is weak, you get buffering. Buffering is when the picture stops while the app waits for more data. Fixing it means checking all three parts, not just one.
Why Four Screens Cause Buffering
One screen rarely has problems on a decent connection. Trouble starts when several screens compete for the same internet line. Here are the main reasons.
Your Internet Speed Is Shared
Your internet plan gives your whole home one total speed. Every TV, phone and laptop takes a slice of it. Four live streams can use up most of that slice fast.
A common rule of thumb is about 25 Mbps for one 4K stream. Mbps means megabits per second, a measure of internet speed. By that rule, four 4K screens could need around 100 Mbps, plus extra room for other devices.
Wi-Fi Gets Crowded
Wi-Fi is radio, so walls, distance and other networks weaken it. When four TVs share one Wi-Fi signal, each one gets less. A screen far from the router often buffers first.
Your Internet Provider May Slow Streams
Some internet providers use throttling. Throttling means slowing down certain kinds of traffic on purpose, often at busy evening hours. Video streams are a frequent target, which is why buffering can get worse at night.
What SubTV IP Brings to a Four-Screen Home
SubTV IP (subtvip.store) is a premium streaming subscription built for high performance. Here is what its own fact sheet lists:
- 99.9% uptime: uptime is the share of time servers are online and working.
- Anti-freeze server cluster: a cluster is a group of servers that share the load, so one busy server does not stall your stream.
- 4K / 60 fps HEVC streams: 4K is a very sharp picture, and 60 fps (frames per second) gives smooth motion.
- Instant activation: your access starts right after you order.
- Plan lengths: 1, 3 or 12 months.
- Secure payment: options include PayPal and credit card.
- WhatsApp support: you can message the team for setup help.
HEVC, also called H.265, is a way to compress video. It shrinks the file size while keeping the picture sharp. Smaller streams put less strain on your internet, which matters a lot with four screens running.
One important tip: before you order, ask WhatsApp support how many screens your plan covers at once. Pick the plan that matches the number of TVs in your home.
Wired vs Wireless: Which Connection Works Best?
How each TV connects to your router makes a big difference. The table below compares the usual options for a home with four screens.
| Connection Type | Speed and Stability | Best Use in a 4-Screen Home |
|---|---|---|
| Ethernet cable | Most stable; not affected by walls or radio noise | Main TV or the screen used most for 4K |
| 5 GHz Wi-Fi | Fast at short range; weaker through walls | TVs in the same room or next to the router |
| 2.4 GHz Wi-Fi | Reaches farther but slower and more crowded | Distant rooms, ideally at lower quality settings |
| Mesh Wi-Fi system | Spreads a strong signal across several rooms | Large homes with screens on different floors |

How to Set Up Four Screens Without Buffering
Follow these steps in order. Each one removes a common cause of buffering.
- Test your speed. Run a speed test at the time of day you watch most. Check that it fits four streams plus your other devices.
- Wire your main TV. Use an Ethernet cable for the screen you watch most in 4K.
- Use 5 GHz Wi-Fi for nearby screens. Connect TVs close to the router to the 5 GHz band.
- Change your DNS to 1.1.1.1. See the steps below.
- Set the buffer to 5,000 ms. See the steps below.
- Use a supported player app. Pick one from the list in the next section.
- Restart everything. Turn off the router and devices, then turn them back on so the new settings apply.
Change Your DNS to Cloudflare (1.1.1.1)
DNS works like the internet's phone book. It turns names into addresses your device can reach. SubTV IP recommends Cloudflare DNS (1.1.1.1) as part of its ISP anti-throttling setup.
The easiest way is to change it once on your router. Open the router's settings page and find the DNS field. Then enter 1.1.1.1. This way, every screen in your home uses it automatically.
You can also set it on each device. Look in the device's network settings for the Wi-Fi or Ethernet connection. Choose manual DNS and enter 1.1.1.1.
Set the Player Buffer to 5,000 ms
A buffer is a small store of video the app loads ahead of time. If your internet dips for a moment, the app plays from this store instead of freezing. The recommended size is 5,000 ms, which equals 5 seconds.
Open your player's settings and look in the playback or advanced section. Find the buffer or cache option. Then set it to 5,000 ms on each of your four screens.
Supported Devices and Player Apps
Using a supported setup avoids many problems before they start. SubTV IP works with these devices:
- Fire TV Stick 4K Max
- Samsung Smart TV (Tizen)

A player app is the program that plays your streams on the screen. These player apps are supported:
- TiviMate 5.x
- IBO Player Pro
- IPTV Smarters Pro
- Kodi 21
- Flex IPTV
Not every app runs on every device. Check that your chosen app is available on your device's app store. If you get stuck, WhatsApp support can point you to the right match.
Your Next Step
Start with your home setup: test your speed, wire your main TV, and apply the DNS and buffer settings. Then choose a 1, 3 or 12-month plan that covers all your screens. Activation is instant, so you can start watching right after you order.
Frequently Asked Questions
How much internet speed do I need for IPTV on 4 screens?

Why does my IPTV keep buffering at night?
Evenings are peak hours, when networks are busiest and some providers throttle video traffic. Setting Cloudflare DNS (1.1.1.1) and a 5,000 ms buffer can help. A wired connection also keeps your main TV steadier.
What buffer size should I use to stop IPTV freezing?
