FAQ's: USB Monitors

What is a USB monitor?

A USB monitor is an external portable monitor that is connected to the laptop or PC via a USB-C or USB-A port.

The screen is supplied with power via the USB connection via the laptop / PC and, depending on the USB type, also transmits video and audio signals. This saves you an HDMI cable in many cases and you can completely do without an additional charger.

This enables you to use several applications at the same time without having to constantly minimize them and call them up again. This makes your work easier if you want to edit several documents at the same time, for example.

Some USB monitors can also be connected to game consoles or smartphones.

Who should use a USB monitor?

Using multiple monitors increases productivity at work. Many already use such a set-up at home or in the office.

But what should you do if you have to leave your actual workplace but still want to work productively on the go?

A mobile USB monitor is the perfect solution for this. These devices are light, slim and you can easily connect them to your laptop or tablet. In the event that your tablet or laptop does not have the necessary connection, you can buy an adapter.

But a purchase is not only worthwhile for people who like to use an additional monitor for work-related reasons.

This extension is also an interesting solution for gamers, as you can play with friends without sharing the screen.

In what size should I buy a USB monitor?

Which size is right for you depends heavily on your own needs and area of use.

When it comes to the size of monitors, one always speaks of the screen diagonal, which is specified in inches. One inch is 2.54 centimeters.

Here is a small overview of the most common USB monitor sizes:

  • 7 “- 17.78 cm
  • 8.9 “- 22.60 cm
  • 11.6 “- 29.46 cm
  • 13.3 “- 33.78 cm
  • 14 “- 35.56cm
  • 15.6 “- 39.62 cm

We recommend that you base your choice of screen diagonal on the size of your laptop. For example, if you have a 13 inch laptop, it makes sense to buy a 13.3 inch USB monitor.

This makes your work surface appear more symmetrical and the external monitor fits into a bag with the laptop.

If you want to use a mobile monitor to expand your smartphone display, a small screen diagonal such as 7 or 8.9 inches is sufficient.

What is the difference between USB Type-C and USB Type A?

In the case of USB connections, a distinction is now made between Type-C and Type-A, whereby Type-A is the standard USB connection that you know at home.

A distinction is made between 2.0, 3.0, 3.1 and 3.2 for USB plugs.

While USB 2.0 has a transfer speed of 480 Mbit / s, USB 3.0 is up to ten times faster with a maximum speed of 4.8 Gbit / s. USB-C 3.1 can transfer data with up to 10Gbit / s and 3.2 with a maximum of 20Gbit / s.

A USB-C connector is smaller than a Type-A and is also structured differently. This makes it easier to connect devices with USB-C. Another advantage is that the USB-C connection can transmit audio, network and video signals at the same time. In addition, it serves as an energy source.

In addition, a USB-C socket takes up much less space, which enables the manufacturer to make the device thinner.

Types of USB Monitors

With USB monitors you can choose between one with and without a touchscreen. There is hardly any difference in price between the two. However, you can achieve a higher resolution with a USB monitor without a touchscreen.

Depending on the area of application, you can choose one of the two categories. We would like to make your decision easier for you through the following sections.

USB Monitor with Touchscreen: Advantages & Disadvantages

The advantage of a USB monitor with a touchscreen is obvious: you can operate it by touching it with your fingers. This makes it easier to control, as the monitor can be operated more intuitively.

But there are also differences when it comes to touchscreens. On the one hand, there are those that are built into most cell phones and tablets.

They are known as dual touch because the screen recognizes up to two points of contact that can act on the screen.

A well-known gesture, for example, is zooming with two fingers.

But there is also another variant that recognizes more than two fingers at the same time. This allows several people to operate a screen by hand at the same time. In addition, you save yourself the purchase of a mouse or keyboard.

Advantages

  • Easy and intuitive operation
  • No mouse or keyboard necessary

Disadvantages

  • Lower resolution
  • Collects dirt quickly

USB monitors are usually only sold with a resolution of up to Full HD. In addition, the constant touch with the fingers quickly dirty the screen.

USB Monitor without Touchscreen: Advantages & Disadvantages

USB monitors without a touchscreen are sold with a resolution of up to 4K. Especially if you like to play games or use graphically demanding software for video or image processing, a higher resolution makes a big difference.

Another advantage is that the screen does not get so dirty because it hardly ever comes into contact with anything.

Advantages

  • Resolution up to 4K
  • Does not collect dirt as fast

Disadvantages

  • Operation not so intuitive
  • Mouse and keyboard required

This decision again depends very much on your own needs. If you like to enjoy high resolution, a USB monitor without a touchscreen definitely makes more sense. If you like to use touch and value intuitive operation, then a monitor with a touchscreen.

USB Monitors: Purchase Criteria

In the following we will show you which aspects you can use to decide between the multitude of possible USB monitors.

The criteria with which you can compare the USB monitors with each other include:

  • Weight
  • Connections
  • Resolution
  • Reaction time

In the following paragraphs we will explain to you what is important for the individual criteria.

Weight

Since a USB monitor is a mobile portable device, weight plays an important role. The rule is, the easier the better. Of course, when you’re on the move you don’t want to carry unnecessary weight with you.

Connections

Some USB monitors are also equipped with an HDMI or VGA connection. As a rule, however, a VGA connection is rarely installed.

Sure, multiple connections have the advantage that you can work more flexibly with your monitor. The disadvantage, however, is that these must of course also be installed separately, which is not exactly space-saving. This makes the USB monitor thicker.

In most cases, a USB-A or USB-C port is sufficient, as there are several different ports available on your main device anyway.

Resolution

When it comes to resolution, there are different categories that you can choose between:

  • Full HD (1920 × 1080 pixels)
  • WQHD (2,560 x 1,440 pixels)
  • 4K (3840 × 2160 pixels)

The resolution is always specified with the number of pixels in width and height. The more pixels, the better the resolution, since more information (image points) can be projected onto the same surface. With the increase in information, the picture becomes sharper.

Reaction Time

Response time is an important factor in monitors. It provides information on how quickly a pixel can change its color. Especially with fast movements, the pixels have to react very quickly so that the image does not become distorted or spongy.

The response time is given in milliseconds, whereby the following applies: the shorter the response time, the better. The manufacturers usually specify an optimal value which in practice cannot usually be adhered to.

However, monitors these days are basically fast enough that in most cases there are no problems.

Facts about USB Monitors

How do I clean a USB monitor?

To avoid damage, it is best to use a microfiber or billen cleaning cloth to clean your USB monitor. Before you start cleaning, it is important that you unplug the monitor and wait a moment to avoid short circuits.

If your monitor is very dirty, you can use a TFT cleaner. The cleaner should never be applied directly to the screen.

When cleaning, you should ensure that the cloth used is not too damp so that no liquid penetrates the monitor. We do not recommend using detergent, window cleaner or the like.

Can a USB monitor be connected to a smartphone?

Depending on the monitor, smartphones can simply be connected with a cable. Simply connect the mobile phone to the monitor via the cable and select the correct output.

Depending on the connections of your monitor and smartphone, this may only be possible in combination with an adapter.

Can I connect my USB monitor to the console?

Yes, it is basically possible. Please pay attention to the information provided by the manufacturer. Not all monitors are suitable for use with an Xbox X Series, Play Station 5 or Nintendo Switch.

The information related to this is usually given on the product page.

Can I operate my USB monitor with a power bank?

You can easily operate your USB monitor with a power bank. For a long operating time, however, you should buy a power bank with a medium or high charging capacity.

The mobile charging stations are now available with up to 50,000 mAh (milliamper hours).
