I'm eagerly awaiting more news concerning the new USB version of Pixel Qi's outdoor viewable 10" LCD screen. At 1.5W at full power this sounds like the ideal solution that we have all been waiting for.
A German company named Display Solution AG is going to produce a combination of the well-known Displaylink USB video display technology combined with the aforementioned Pixel Qi display. I've tested Displaylink devices earlier, they are fast enough for a chart display and general 2D use. 3D or video is a bit of a challenge, but I don't think that's what most yachties are looking for.
Once this happens all that needs to happen is for someone to package this in a IP 67 case and we've got the perfect marine display!
