Answers.Body: <p>I think it is possible to do live projection using <a href="https://madmapper.com/" rel="nofollow noreferrer">Mad Mapper</a>, but fundamentally I think you won't get a usable result.
  Sending a single HDMI output from your computer to a projector, and then projecting this across multiple different panels means the pixel resolution on the individual panels is going to be much lower.<br />
  Unless you have some sort of mammoth video card with multiple outputs, I'm not sure this would generate usable, readable output for the purpose you propose.</p>

Body: <p>I'm using a projector to display the content of my computer, as one would do with a regular screen. Now I want to do the projection on several panels that have different orientations. Hence I'm looking for a projection mapping solution.</p>
  
  <p>Is it possible to do projection mapping with the HDMI output of my computer as projected content? If it is, could you recommend me a tool to do so? So far, the projection mapping softwares I've found can only project content that is internal to the computer and defined in advance, such as solid colors, video or pictures.</p>
