I have the 2050a with the picture keyed in nicely, but there is a dim strip of light running top to bottom just off my screen on the right side. The picture is great, I am just wondering why the light is there

Make sure all scaling and keystone correction is set at 0. If either of these are used you are no longer using the full resolution of the DMD and pixels not used will show up as stray light.
