Future versions of DevMan will show, did you installed proper drivers for every device or not. (in other words, is it possible accelerate work of video or it works at maximal speed = is it necessary replace universal device driver to accelerated or not)
Our experience with service of Windows users shows that huge amount of Windows computers are configured not properly: main drivers are not installed so computers work not properly. Of course, Windows has all means to fix this problems. OS/2 will get the assistant in 2020 only.

* red vertical stripe - the device doesn't have driver or wrong driver
* orange indicator - a driver is installed but it should be replaced to accelerated one,
* green stripe - optimal driver is installed
