An on camera video monitor is a small external screen that mounts above or beside your camera. It gives you a larger image than the built in display, which helps with focus, framing and exposure when you shoot video. Some also add tools such as focus peaking, waveforms and false color. Think about your camera’s video output, the rig you already have and whether you shoot indoors or in bright daylight.
We have not used these products ourselves, so this guide does not rank models. It covers the features and construction points that matter, so you can read any listing and decide which monitor fits your camera, your workflow and your way of shooting.

What to Look For
| Factor | Why it matters | What to check |
|---|---|---|
| Screen size | Larger screens show more detail, while smaller ones keep the rig light. | Compare diagonal size against the weight and bulk of your camera setup. |
| Inputs and outputs | The monitor must accept the signal your camera sends. | Check HDMI or SDI, the connector size and any pass through output. |
| Brightness | Outdoor shooting needs a screen that stays readable in daylight. | Look at the stated nits and whether a sun hood is included or sold separately. |
| Exposure tools | Assist tools help you judge focus and exposure at a glance. | See which tools are listed, such as peaking, histogram, waveform and false color. |
| Power options | A monitor that runs out of power ends a shoot early. | Check battery plate type, USB or DC input and the runtime the maker states. |
| Mounting points | Good mounting lets you place the screen where you can see it. | Look for threaded holes, a tilt arm and the weight of the included mount. |
| Touch and controls | Menus can slow you down during a take. | Check for touch control, physical buttons and custom shortcuts. |
Setup and Care Tips
- Pair the monitor with the cable length and connector type your camera port can hold firmly.
- Use a cable clamp or strain relief so a tug does not damage the camera port.
- Check the camera’s output menu so the monitor receives the signal format you want.
- Place the screen at a tilt that avoids glare and keeps it in your line of sight.
- Carry spare batteries and clean the screen with a soft dry cloth.
Mistakes to Avoid
- Choosing a monitor that is too large and heavy for a small camera or gimbal.
- Forgetting that some cameras limit their output while recording.
- Relying on screen color alone when judging exposure in bright light.
- Ignoring how the monitor is powered and how long a shoot will last.
- Leaving a full length cable dangling, which can catch on gear and strain the port.
FAQ
Do I need SDI or is HDMI enough?
HDMI is common on mirrorless and DSLR cameras and works well for short cable runs. SDI locks in place and handles longer runs, which is why it appears on cinema and broadcast gear. Match the monitor to the output on your camera.
Can a phone or tablet replace a dedicated monitor?
It can work for casual shoots with a capture device or wireless link. A dedicated monitor usually offers brighter screens, locking connectors and built in tools. Weigh convenience against reliability.
The Short Version
Begin with the connection your camera offers, then compare brightness, tools and power. A monitor that matches your rig and your shooting conditions will help more than one with a long feature list.
