Re: What I want to know is
We have a Linux-based signage system at work from MVix. It works fairly well, but still does soil the bed from time to time.
The thing is, it mostly displays PowerPoint files. That's the thing to keep in mind - the component that displays the image on the screen is only half of the solution, the other half is the backend software that lets the semi-sentient droids in HR determine what is going to be shown on the screen. And, for the most part, they build their slideshows in PowerPoint and import them, in spite of the fact that the MVix software can display text, graphics, and video, and do timed screen wipes, fades, etc possibly even better than PowerPoint does. But it's the familiarity that they want, so they stick to what they know. And it's the powerpoint files that cause the little display computer to crap its pants once in a while. Even in a non-Microsoft ecosystem, PowerPoint is still the root of all evil.
