Comment Plugable USB Video Adapters (Score 2) 197
OP mentioned that the screens are just showing browser windows. USB-attached displays perform surprisingly well for that, and have the advantage of working with any Windows PC.
Here's a video showing 4 displays: https://youtu.be/KKcMqCAYkpk And one showing 14: https://youtu.be/heB94f6FHd8
Full disclosure: I work for the company that made these videos. One important thing to note is the 14 monitor demo was done with a pure USB 2.0 system. Modern USB 3.0 systems have lower limits in terms of how many USB devices can be connected and you may not be able to replicate this total number (we have a warning about this in the description and in a pop-up in the video).
Another option based on 'mushero' mentioning an ideal solution would be "My dream would be a quad-HDMI device in Chromebox form factor" is the Zotac Magnus EN970 with quad HDMI outputs -> https://www.zotac.com/us/produ... More expensive per display of course compared to our products and not quite as small as a Chromebox, but it is an option nonetheless and we want you have the best solution for your needs, even if doesn't necessarily include our products.
Thanks,
Bob
