A monitor can work as a TV if it has the right input and speakers
Yes, you can use a computer monitor to watch television, but it requires the right equipment and connections. Most modern monitors have HDMI ports, which accept video signals from cable boxes, streaming devices, and antennas. The catch is that many monitors have no built-in speakers or very poor ones, so you will usually need external speakers or a soundbar to hear anything.
The simplest setup is a monitor with HDMI input, an HDMI cable, and a device that sends video to it—a cable box, satellite receiver, streaming stick, or over-the-air antenna box. Plug the HDMI cable from your source device into the monitor's HDMI port, switch the monitor's input to that HDMI channel, and the picture appears. Audio is a separate problem you solve with speakers.
Key Takeaways
- Your monitor must have at least one HDMI input port; older monitors with only VGA or DVI ports cannot display modern TV sources without an adapter.
- Most monitors have no speakers or speakers too small to use for TV; you will need a separate soundbar, powered speakers, or headphones to hear audio.
- Cable boxes, satellite receivers, streaming devices, and antenna boxes all connect to a monitor via HDMI in the same way a computer does.
- Some monitors have audio output jacks that let you send sound to external speakers; check your monitor's manual to see which ports it has.
Check what input ports your monitor actually has
Before you buy anything, look at the back of your monitor. Most monitors made in the last ten years have at least one HDMI port. Some have two or three. If your monitor is older or was a budget model, it might have only VGA (a blue 15-pin connector) or DVI (a white connector with pins), which do not work with modern TV sources.
Look for a label on the back or in your monitor's manual that lists the ports. HDMI ports are small, flat, and rectangular. If you see only VGA and DVI, you would need an adapter to convert HDMI to one of those older formats, and adapters can introduce picture quality problems. It is simpler to use a monitor that has HDMI built in.
Also check whether your monitor has a headphone jack or audio output. Many monitors have a 3.5mm audio jack on the back. This lets you connect speakers or headphones directly to the monitor instead of to your TV source. Not all monitors have this—some require you to run audio cables separately from the video source.
Choose a TV source device and connect it with HDMI
Any device that outputs HDMI video can feed a monitor. The most common choices are a cable or satellite box, a streaming stick (Roku, Amazon Fire Stick, Apple TV), an over-the-air antenna box, or a gaming console. Plug an HDMI cable from the output port on your source device into an HDMI input port on the monitor.
If your monitor has multiple HDMI ports, you can label them or remember which one you used. Some monitors let you name inputs in the on-screen menu, which helps if you plan to switch between a cable box and a streaming device. Once the cable is connected, turn on both the monitor and the source device, then use the monitor's input button (usually on the front or side) to select the HDMI channel you plugged into.
The picture should appear within a few seconds. If it does not, check that the HDMI cable is fully seated in both ports, that the source device is powered on, and that you selected the correct input on the monitor. A loose cable is the most common reason a monitor shows no picture.
Solve the audio problem with external speakers
This is the step most people overlook. Monitor speakers, when they exist at all, are tiny and tinny. They sit inside the monitor's plastic frame and were designed for computer alerts, not for watching TV. If your monitor has a headphone jack, you can plug powered speakers or a soundbar into it. Powered speakers have their own amplifier built in, so they work without extra equipment.
If your monitor has no audio output jack, you have two options. First, run an audio cable directly from your TV source device to your speakers. Most cable boxes and streaming devices have a headphone jack or audio output ports (red and white RCA connectors). Second, use wireless speakers or a soundbar that connects via Bluetooth to your source device instead of to the monitor.
A soundbar is often the easiest choice because it sits in front of your monitor, takes up little space, and connects with a single cable or wirelessly. Budget soundbars cost $30 to $80 and sound far better than monitor speakers. If you already have powered computer speakers, those work fine too—just plug them into the monitor's audio jack or into your TV source device.
Adjust picture settings for TV viewing
Computer monitors are optimized for sharpness and color accuracy at close range. When you use one as a TV, you may sit farther away, and the picture might look too bright or the colors too vivid. Most monitors have an on-screen menu (accessed by buttons on the front or side) where you can adjust brightness, contrast, and color.
For TV viewing, try lowering the brightness slightly and reducing the color saturation if the picture looks oversaturated. Some monitors have preset picture modes—look for one labeled "Movie" or "Standard" instead of "Dynamic" or "Vivid." These presets dial back the artificial sharpening and color boost that work well for spreadsheets but look unnatural on film and television.
If your monitor has a refresh rate setting, leave it at the default. TV content runs at 60 Hz, which is what your monitor will display by default. You do not need to change this for TV use.
Understand the limits of using a monitor instead of a TV
A monitor works as a TV, but it is not the same as a television. Monitors have smaller screens than most TVs—a 27-inch monitor is considered large, while 55-inch TVs are common. If you sit close to the screen, a monitor is fine. If you want to watch from across a room, you will notice the picture is smaller and harder to read.
Monitors also lack the tuner that a TV has. A TV tuner is the part that picks up broadcast channels from an antenna or cable line. A monitor cannot do this on its own. You need a separate device—a cable box, satellite receiver, or antenna box—to receive the signal and send it to the monitor via HDMI. This is an extra piece of equipment and an extra expense.
Some monitors have poor viewing angles, meaning the picture looks washed out or changes color if you sit to the side. TVs are designed for viewing from many angles. If multiple people will watch from different positions, a TV is a better choice than a monitor.
When a monitor makes sense as a TV
Using a monitor as a TV works best in specific situations. If you have a small space—a bedroom, dorm room, or office—and already own a monitor, adding a streaming stick and speakers is cheaper than buying a TV. If you use the same screen for both computer work and occasional TV watching, a monitor with good HDMI input saves you from needing two screens.
A monitor is also useful if you want a second screen in another room without the cost of a full television. You can use an inexpensive streaming device and basic speakers to turn an old monitor into a functional TV for light viewing.
However, if you plan to watch TV as your primary activity, sit far from the screen, or want a large picture, a television is the better choice. TVs have larger screens, better speakers, built-in tuners, and are designed for the way people actually watch television.
Frequently Asked Questions
Do I need a special monitor to use it as a TV?
No. Any monitor with an HDMI input port works. You do not need a monitor marketed as a "TV monitor" or anything special. A standard computer monitor from the last ten years almost certainly has HDMI. Check the back of your monitor or its manual to confirm.
Can I watch cable TV on a monitor without a cable box?
No. A monitor has no tuner, so it cannot receive cable signals on its own. You need a cable box from your cable provider, or you can use a streaming service instead. An antenna box lets you watch broadcast channels if you have an antenna.
What if my monitor has no speakers at all?
You must use external speakers. Plug powered speakers into the audio output jack on your monitor (if it has one), or run an audio cable from your TV source device directly to the speakers. A soundbar is the simplest option and takes up minimal space.
Can I use an old monitor with only VGA ports?
Not easily. VGA does not carry audio, and HDMI-to-VGA adapters can reduce picture quality. If your monitor has only VGA, DVI, or DisplayPort, it is usually better to use a different monitor or buy a TV instead of dealing with adapters.
Will a monitor work with a Roku or Fire Stick?
Yes. Plug the streaming device into an HDMI port on the monitor, connect speakers to the monitor's audio jack or to the streaming device, and you are done. Streaming devices work the same way on a monitor as they do on a TV.
