USB Monitor Adapter or how I looked for the meaning of life

Hello. I got an idea. I decided to bring it to life.

I got two monitors, almost free. Where I got the monitors is a completely different story. Since I do not have a stationary computer, and I have a laptop, to which one monitor was already connected, I decided to make a system of over999 3 monitors, as in the best Hollywood action films. Yes, and I’m bored and lonely in the evenings it will be more convenient to work with the code, I'm kind of like a programmer. But since this is a laptop and it has only 2 monitor outputs (one VGA and one HDMI), and therefore - only 2 out of 3 monitors can be connected to it, the ways to solve my problem should have become completely non-standard and interesting.

As a result, I searched the Internet for solutions and somewhere out of the corner of my eye I noticed that there are such devices to which you can connect one computer and get access to several monitors. This device is called "Splitter" or Splitter. It looks something like this:


As a result of a detailed study, I took it in the store for a day, I realized that the device is not quite suitable for my purposes. The whole problem is that the “Splitter” allows you to only duplicate the screen, but not expand it to multiple monitors. That is why this option was excluded from the list of suitable solutions by me. Then I came across another device - USB Monitor Adapter. In the future, the article will focus on him.

The USB Monitor Adapter (hereinafter referred to as the adapter) is a small video card connected via USB. Most of these devices are based on DisplayLink technology, which allows you to organize video transfer via USB.

I don’t go into the details of DisplayLink technology, I’ll just tell you what can and cannot be done with the adapter.

A search for a description of the device gave me the following information (which, incidentally, was confirmed by sellers on the top of the head):
You can:
- Connect another monitor using one adapter (you want 2 monitors, buy 2 adapters);
- Use it to display text information and pictures on an additional monitor (maximum to see some kind of video);
- Display the maximum resolution of 1920x1080 (not on all adapters).

You can’t:
- Everything else.

But despite the limitations, I decided to give it a try.

I purchased the ESPADA H000USB adapter in one very popular online store. Here's what it looks like:


At my own risk, I plugged this whole thing. A friendly driver installation window immediately popped up, which I used.

Suddenly the third monitor started working and I immediately started testing all the items for which the adapter was intended.
The monitor worked and displayed an image. The video also worked. It would seem that this is all I need. But I went ahead and started the game. In the settings, I chose this monitor and everything went perfectly. Even the FPS did not fall. So all thoughts about the inability of the adapter to output something other than text and video were wrong. Everything else is most likely true, since I did not connect another adapter, and the resolution above 1920x1080 is not supported by my monitor.

And the most important thing for gamers. The adapter is not capable of working out of the box in the mode of converting from 3 monitors to one (perhaps this is somehow solved with the help of straight hands and experimenting with software), that is, playing one game at the same time on 3 monitors (although the programs are displayed can). To make it clear what I mean:


Conclusions: as a result, I got what I wanted. Namely - a workstation of 3 monitors (not counting the laptop monitor). Now I can safely write code, surf the Internet and print this article almost simultaneously:


If you still want to play, it’s easier to get a good desktop computer - and go to battle!
