Pixell can provide remote configuration assistance services, often times for free.

Whether it's an FX4 array programming job with the software application Wall Designer, as shown below,
or programming a custom resolution EDID with an unusual aspect ratio or signal timing for a capture card, we can help. With the infinite number of  video signal and monitor/projector arrays, it's impossible to list every possible service that could be needed, but we are adept at handling unusual requirements.
