Things to consider when buying a portable monitor

You probably don’t have much experience buying a portable monitor yet. They have appeared on the market relatively recently and are now very popular. The more mobile we become, the more complex work becomes, games have multiple layers, and we use different devices so we need more screen space.

After you experience a portable monitor, you’ll wonder how you ever managed to go so long without one.  While many of the terms are the same as for regular computer monitors, there are a few specific things to look out for before investing in a portable monitor. This guide will help you make the best choice for your needs.

Screen size

This is an important factor, and largely depends on how you want to use it and what device you are using. For a mobile device or simple games, you may be satisfied with a smaller screen. A 14 to 15.6 inch screen is sufficient for most applications.

Height and weight

Some portable monitors are more portable than others. Most are light and impressively thin, but some are a bit more massive. If you plan to take a portable monitor with you regularly, make sure it is compact and lightweight.


Most modern portable monitors are highly compatible and work with most devices and gadgets, but make sure they work with the specific devices you want to use now and possibly in the future.

Connection and power supply

One of the reasons for the popularity of portable monitors is the advent of the USB-C port. This allows power and data to be transferred simultaneously over the same cable. This simplifies the use of the system considerably. Connecting and disconnecting is faster, less cumbersome and no tangled cables.

Most monitors have one USB-C port, and some have two or more. Make sure the laptop or device you are connecting to supports this feature, as older USB-C ports may not allow you to transfer data and power through one port. Thunderbolt 3 usually works too, but check just to be sure.

Otherwise, a USB-A or USB 3.0 port is often used to power the monitor and an HDMI port for video and audio.

Another useful feature supported by some monitors is reverse charging. This means you can use a portable monitor to power your laptop or device. The power saving mode is also convenient. This function reduces the brightness so that the device consumes less power.

Current consumption

This is an important factor to consider. Some portable monitors are very power-hungry and quickly deplete the main unit if you use them without power. Others are much more economical and consume a minimal amount of energy. This is an important factor if you want to use the monitor on the go.

Ease of use

We have enough on our minds without hooking up a portable monitor. The easier it is to install and use, the better.

Some monitors require software to be downloaded in order to work. It’s usually quick and easy, and only needs to be done once, so it’s not a big deal. But most are ready to be plugged in.

You want to be able to change the brightness, contrast, color mode and other properties of the screen. It may also be necessary to change the orientation from landscape to portrait or vice versa. Some can do this automatically, which is very convenient.

The OSD (On Screen Display) is a good feature. This way you can easily make such changes. Some allow you to configure settings that you can save for different circumstances.


Most portable monitors do not have speakers and rely on the sound from the main unit. If you want this feature, you should look for a model with speakers. Some have an audio output, which may be useful for some.

Screen resolution and features

The average portable monitor has a resolution of Full HD or 1920 by 1080 pixels. That’s quite a resolution. They range from 1366 x 768 pixels to QHD+ with a resolution of 3200 x 1800 pixels.  Do not set the resolution drastically different from that of your laptop or primary device, as this will not provide a good user experience.

Other factors to consider are brightness and color range. Expect less brightness than other devices. This is mainly done to reduce energy consumption.

Response speed and refresh rate are two other things to watch out for, especially for gamers or people using graphics-intensive applications. The average effective refresh rate is 60 hertz, but some applications may require a higher value for smooth playback. The faster the reaction time, the better.

Suitable for touch screen

This is not typical for portable monitors and has not yet been approved. If you need this feature, there are several options. They will be slightly more expensive than the average portable monitor. To use this feature effectively, you also need to make sure it is very stable.


Prices range from just over $100 to several hundred dollars for some. Think about your budget. Avoid cheap, low quality models as they will disappoint you and are unlikely to last long. If your budget is limited, there are several affordable options that still offer good performance, quality and durability.
