The idea behind portable monitors is very simple. In the end, we’re talking about a normal screen as many. But why do this kind of monitor and display became so popular? Let’s have a look.

Portable Monitors And Portable Gaming Monitors: the reasons behind their popularity

With the increasing usage of USB type-C connector as the main source for video and audio, the easiness of plugging new monitors into your multimedia devices created a new need. This need was to extend original laptop screens and it was the first reason behind the increasing popularity of this product.

But that’s not the only reason. Over the last years, the launch of new gaming consoles, such as the Nintendo Switch, focused on portability and the minimalization of accessories brought new needs. You can use portable monitors, in fact, together with your portable gaming console and grant yourself a better and bigger screen for your games. All these consoles started to feature USB Type-C connectors and it’s becoming super easy to connect them to portable gaming monitors.

So, after a few years of a light shyness of the major manufacturers, the market promoted more and more 4k portable monitors as a nice-to-have accessory both for business and gaming needs. Nowadays the offer is quite wide and new models are going to come out over the next months and years.

For all these reasons, we decided to come up with this guide about the best portable monitors (with battery built-in and not).

What To Look For In A 4k Portable Monitor

If you’re a gamer, you know that having a 4k portable monitor is a choice that needs to be picky. We already spoke about gaming monitors in other articles, so we know already that many factors need to be considered.

But for portable monitors, the topic is a little bit different. When it comes to portability, you may want to put more attention to specific characteristics than others. The guide of today is actually going to consider the durability of the battery built-in into the monitor, as one of these key components.

Portability as a factor, but not as the only one

If you’re not able to plug your portable monitor into AC, you need to have a good battery life, in order to enjoy your product. Additionally, you may need to have a monitor that is easy to transport. Thus, the weight of a portable monitor has to be taken into serious consideration.

Last, but not least is the size of the display. If you plan to use your monitor to extend your original laptop screen, then you may need a bigger diagonal. A good diagonal can, in fact, allow you the possibility to open more files and documents on the same screen. If you are going to buy a monitor for business reasons, you want this monitor to increase your productivity. Therefore, the display diagonal has to be considered as well.

We did not mention so far the resolution of the display, because this is always to be considered, but the better resolution means a higher price. 4k portable monitors are becoming the standard in this regard. So in the end, the weight of this factor on your purchase is just up to your budget.

If you’re a gamer then you will need to consider the refresh rate. The best portable gaming monitor is the one with an high refresh rate and a very good resolution at the same time.
