[Q] HDMI output settings for Amlogic S802 and other Android devices - Android Stick & Console AMLogic based Computers

I have a generic Amlogic S802 (MXIII) device that I feed to my Viewsonic Pro8200 projector. I have a display issue, and I know the general principle of fixing it, but I can't seem to find a way to do it in Android.
The problem:
My black levels are crushed, or rather they are completely destroyed. To get an idea of what I see on my projector, I can only see the last 3 boxes (out of 20 boxes) shown when you follow the link (can't post link): Google "lagom black level" and it should be the first result.
This makes watching most of my favorite TV content and movies a miserable experience (e.g., Walking Dead, Game of Thrones).
The solution on a different OS:
I previously had this problem with my projector when I had a Windows-based HTPC connected. I fixed it by changing the video pixel format setting to RGB full in Catalyst. It had been set to RGB limited by default, and that was causing my blacks to be crushed (#racismnotdead).
What can I do in Android?
I have gone through the media box settings and Android settings and have found no option to adjust the way HDMI is outputted. Is there a conf or prop file I can edit to force RGB full? Is there any other way to tweak HDMI output settings. Does a custom ROM exist with these options that will work on my generic Amlogic S802 device?
I have been digging through threads on this site and other forums, and I have not found any describing a similar problem. Maybe there aren't many people with really cheap projectors.

More details
I'm honestly not surprised that this has no replies, they'll probably come in months down the road.
Anyways, I have some more details. My projector has three modes related to HDMI color space: Auto, RGB, Ycbcr. Booting the device in each of those modes has no effect on the black levels.
However, I did find something that had an actual affect on the black levels. When I set the HDMI output to 576p 50 Hz or 480p 60 Hz, I could see 14 out of the 20 black level boxes (Nagom LCD calibration website) with daylight creeping in the room. That's fantastic, but the UI and videos look like trash at those resolutions, so it's at best additional information and not even close to a remedy.
I am ready to buy a BenQ projector at Wal-Mart with the intention of returning after a couple of weeks just to give myself a reprieve from this color crushing nightmare of an excuse for a home theater system.

I'm going to be using a 808b stick that I have and was wondering about getting the Viewsonic, have you found any solution to this problem?
