What "connecting two TVs" actually means
When you want to watch on two TVs at once, you have three real options: run a cable from one TV to another, use a splitter on your cable or satellite box, or subscribe to a second streaming account. Which one works depends on what you're trying to watch and whether you want the same thing on both screens or different things.
The simplest setup — splitting a cable box signal — costs $15 to $40 for hardware and works immediately. Streaming services usually require a second subscription if you want different shows on each TV, though some allow multiple simultaneous streams on one account. Running an HDMI cable between two TVs is rare and only works if they're close together.
Key Takeaways
- A cable splitter ($15–$40) lets two TVs show the same channel from one cable box, but both TVs display identical content.
- Most streaming services allow 2–4 simultaneous streams per account depending on the plan; check your service's documentation to see how many devices can play at once.
- If you want different channels or shows on each TV from cable, you need a second cable box, which usually costs $10–$15 per month from your provider.
- HDMI cables between two TVs don't work for most purposes; one TV must be an input device (like a capture card) for this to function.
Using a splitter to send one cable box to two TVs
A coaxial splitter (the kind with threaded connectors) divides the cable signal coming into your home so it reaches two TVs. You unscrew the cable line where it enters your cable box, screw the splitter onto that line, then run separate cables from the splitter to the box and to the second TV. Both TVs then receive the same channels and must watch the same thing.
The splitter itself costs $15 to $40 depending on quality. You'll also need a second coaxial cable (the thick threaded cable, not HDMI) to run from the splitter to the second TV — these cost $10 to $20. Installation takes 10 minutes if the TVs are in the same room or nearby; if they're far apart, you may need 50+ feet of cable, which gets expensive and can degrade signal quality.
This setup works best when you want the same content on both screens — a sports game in the living room and kitchen, for example. If you want to watch different channels, you'll need a second cable box instead, which your cable provider can install for a monthly fee (typically $10–$15).
Streaming the same account on multiple TVs
Most streaming services allow more than one TV to play from the same account, but the number varies. Netflix allows 2 simultaneous streams on Standard ($15.49/month) and 4 on Premium ($22.99/month). Disney+ allows 4 simultaneous streams. Hulu allows 2 on the base plan and unlimited on the ad-free plan ($14.99/month). Check your service's plan details or account settings to see your limit.
To watch on a second TV, sign into the same account on that TV's app or built-in streaming software. If you hit your simultaneous stream limit, one TV will be kicked off and you'll see an error message. This is a technical limit, not a payment issue — you don't need to pay extra unless you want to upgrade to a higher tier that allows more streams.
Some services, like Max (formerly HBO Max), allow 4 simultaneous streams and let you create separate profiles so family members see different recommendations. Others, like Apple TV+, allow 6 simultaneous streams. Read your service's terms or contact support if you're unsure about your specific plan.
When you need a second streaming subscription
If two people want to watch different shows at the same time and your account has hit its simultaneous stream limit, you have two choices: upgrade to a higher tier (if available) or pay for a second subscription. A second subscription costs the same as the first — for Netflix Standard, that's $15.49/month for a second account.
Some households find it cheaper to upgrade once than to pay for two full subscriptions. Netflix Premium ($22.99/month) costs $7.50 more than Standard but allows 4 simultaneous streams instead of 2, so it may pay for itself if three or more people watch regularly. Do the math for your household before committing.
A second account also gives you a separate profile, watch history, and recommendations, which some people prefer anyway. The downside is managing two logins and two billing cycles.
Running HDMI between two TVs (rarely works)
An HDMI cable physically connects two TVs, but this doesn't do what most people expect. One TV must be set to HDMI input mode and act as a display for the other TV's output. Most modern TVs don't have HDMI output ports — they only have HDMI input. So unless your TV has an HDMI output port (rare on consumer models), this won't work.
If both TVs do have HDMI output, you can run a cable between them, but the receiving TV will only show what the sending TV outputs — usually just its own menu or apps. You can't independently control the second TV or watch different content. This setup is impractical for most homes.
The only common scenario where this works is if you have a capture card (a device that records video) connected to one TV and want to display that feed on another. This is used for gaming streams or video production, not everyday TV watching.
Comparing your options side by side
| Method | Cost | Setup Time | Same Content on Both TVs? | Best For |
|---|---|---|---|---|
| Coaxial splitter | $25–$60 (splitter + cable) | 10 minutes | Yes, always | Cable TV in two nearby rooms |
| Second cable box | $10–$15/month | Provider installation | No, independent channels | Watching different cable channels simultaneously |
| One streaming account (multiple streams) | $0 extra (if within limit) | 5 minutes (sign in) | No, if within stream limit | Families sharing one subscription |
| Second streaming subscription | $5–$23/month (service dependent) | 5 minutes (sign up) | No, independent content | Households that exceed simultaneous stream limits |
| HDMI cable between TVs | $10–$20 | 5 minutes | Yes, but limited use | Specialized setups (gaming capture, video production) |
Troubleshooting weak signal after splitting
If you use a splitter and one TV gets a weak or pixelated picture, the cable signal is being divided between two paths and losing strength. This happens more often with longer cable runs or older splitters. A powered splitter (one with a power cord) amplifies the signal before dividing it and costs $30–$50 but solves this problem.
Before buying a powered splitter, check that your cable isn't damaged and that connections are tight. Loose connectors cause more signal loss than the splitter itself. If the problem persists, contact your cable provider — they can test your line and may replace the splitter for free.
Frequently Asked Questions
Can I watch different channels on two TVs with one cable box?
No. A splitter sends the same signal to both TVs, so they must show the same channel. To watch different channels, you need a second cable box from your provider, which costs $10–$15 per month and requires a technician to install.
Do I need a second Netflix account to watch on two TVs at once?
Only if you've hit your simultaneous stream limit. Netflix Standard allows 2 streams; Premium allows 4. If both TVs are within that limit, you can use the same account on both. Check your plan in account settings to see your limit.
What's the difference between a regular splitter and a powered splitter?
A regular splitter divides the signal equally between two paths, which weakens it slightly. A powered splitter has a power cord and amplifies the signal before splitting, so both TVs get a stronger picture. Use a powered splitter if you see pixelation or weak signal after splitting.
Can I connect two TVs with an HDMI cable so they show the same picture?
Not in the way you're thinking. Most TVs only have HDMI input ports, not output ports, so an HDMI cable won't transmit a picture from one TV to another. If you want the same content on two TVs, use a cable splitter (for cable TV) or sign into the same streaming account on both (for streaming services).
Will splitting my cable signal affect my internet speed?
No. A coaxial splitter only divides the TV signal, not your internet connection. Your modem connects to a separate line or port on the splitter and is unaffected.
