Lately we have been doing some very large projection blends and LED walls. Typical setup involves a Barco E2 and Resolume for backgrounds and video playback. Presentations and other standard content gets sourced at some standard resolution and put in a PIP layer.
We have a show coming up with a 9600X1080 LED wall. No problem for the E2 and resolume on a trashcan mac, but the client also wants to do Powerpoint and Keynote at that resolution! I have never pushed powerpoint past 2k on standard laptops.
Do I need software like PowerShow? Is it stable? Other options include multihead adapters. I always thought of them as a gimic but we are looking hard at them. I think the E2 edid can be set to mimic a multihead but I have not tried it. Any recommendations on hardware or software would be welcome. Thank you.
