Peau,
I was rereading your work on the LED mounts. When you made the slimmed down the bezel, did you angle the LEDs at all, or simply lower the height of the mount?

I just lowered the height so that the bezel would be lower to the screen.  I redid it again after that using some much thicker aluminum rails that gave much better support, as seen in my recent FTIR post on my blog.  That time I put 12 LEDs on each of the four sides and the results were much much better.
