One Remote for Two TVs: Separate Control Explained
Yes, you can use one remote to control two TVs separately, but the method depends on the remote and the TVs. Universal remotes with multi-device memory, app-based remotes, and HDMI-CEC features all offer ways to switch control between different televisions, and some even allow simultaneous control of multiple sets.
How Multi-Device Remotes Work
Most universal remotes store command codes for multiple devices in their memory. You program each TV into a different “device mode”—for example, TV1 on the “TV” button and TV2 on the “AUX” or “CBL” button. Pressing the corresponding mode button tells the remote which TV to send commands to next. This is the most common method and works with both IR (infrared) and RF (radio frequency) remotes.
For a single remote to control two TVs separately, it must have at least two programmable device slots. Many universal remotes offer four or more. You assign each TV a unique code, often found in the remote’s manual or online database, and then switch between them with a button press.
IR vs. RF: What’s the Difference?
Infrared remotes require a clear line of sight to the TV’s sensor. They work well in a single room but cannot control a TV in another room or one hidden behind a cabinet. Radio frequency remotes, on the other hand, transmit signals that can pass through walls, allowing control of a TV in another room without pointing the remote at it.
Some high-end universal remotes use RF to communicate with a hub that then sends IR commands to each TV. This setup allows you to control multiple TVs from anywhere in the house, and the hub can be programmed to send the same command to all TVs simultaneously or to individual ones based on the mode you select.
Using HDMI-CEC for Basic Control
HDMI-CEC (Consumer Electronics Control) is a feature built into most modern TVs and many devices like streaming sticks, Blu-ray players, and soundbars. It allows control of connected devices over the HDMI cable. If both TVs are connected to a single remote’s paired device (like a streaming box), the remote can often control basic functions on both, but switching between them usually requires selecting the correct HDMI input.
However, HDMI-CEC is typically designed for one TV at a time. To control two TVs separately, you would need two HDMI-CEC devices, each paired to a different TV, and then use those devices’ remotes—which defeats the purpose of a single remote. Some advanced universal remotes can integrate HDMI-CEC into their macros, but it’s not a standard solution for multiple TVs.
Choosing the Right Universal Remote
When selecting a universal remote to control two TVs, consider the following:
- Number of devices: Ensure it supports at least two TV profiles.
- Connection type: IR for same-room use, RF for multi-room.
- Programmability: Some remotes allow learning from original remotes, which is useful for obscure brands.
- App control: Many modern universal remotes have companion apps that let you switch devices easily.
- Backlighting and ergonomics: If you’ll use it in a dark home theater, backlit buttons are helpful.
Popular universal remotes from brands like Logitech (now discontinued but still available) and SofaBaton offer multi-device support. Always check the remote’s compatibility list before purchasing.
Common Problems and Solutions
One common issue is that after programming, pressing a button controls both TVs simultaneously. This usually happens if the remote is in a mode that broadcasts to all devices or if the TVs share the same IR code. To fix it, ensure you’ve selected the correct device mode before pressing buttons.
Another problem is that one TV doesn’t respond to the remote. This can be due to a wrong code, a blocked IR sensor, or a dead battery. Try re-programming the remote with a different code from the manual or use the “search” function to find the right one. If the remote uses RF, ensure the hub is within range and not obstructed.
Alternatives to a Single Remote
If a universal remote seems too complicated, consider these alternatives:
- Smartphone apps: Many TVs have official apps that turn your phone into a remote. You can have one app for each TV and switch between them.
- Voice assistants: Amazon Alexa and Google Assistant can control multiple TVs if you have compatible smart TVs or IR blasters. You can say “turn on the living room TV” to control one specifically.
- IR blaster hubs: Devices like Broadlink or Logitech Harmony Hub (discontinued) can send commands to multiple TVs via IR, and you control them through a phone app.
These alternatives often provide more flexibility than a traditional remote, especially if you have many devices.
Frequently Asked Questions
Can I control two TVs with one remote without programming?
No, you need to program the remote with the correct codes for each TV. Most universal remotes require at least initial setup to recognize each TV’s brand and model.
Will a universal remote work with any TV?
Most universal remotes support thousands of brands and models, but some obscure or very old TVs may not have codes available. In that case, a learning remote can capture commands from the original remote.
Can I control two TVs of the same brand with one remote?
Yes, but you may need to assign different device modes to each. Since they share the same IR codes, pressing buttons while in one mode will only affect that TV if you’ve set it up correctly. However, some remotes may not distinguish between two identical models.
Is it possible to control two TVs simultaneously with one remote?
Yes, if the remote has a “simultaneous” or “all” mode, or if you use an RF hub that broadcasts to all devices. This is useful for turning off both TVs at once, but it can be annoying if you want to control only one.
Do smart TVs have built-in multi-device support?
Some smart TVs can act as a hub to control other devices via HDMI-CEC, but they are not designed to control other TVs. You would still need a separate remote or app for each TV.
