hi there, i have a mvs-4-25 that has a pretty dark monitor, it takes a little while for it too warm up and look nice, and even then, it is kinda dark.. was wondering if there are any extra settings to try besides the basic color/rgb/ knobs. ALSO, it takes a little while for the sound to come in, it is really low the first 10 minutes, then it is loud, is that normal? other than that the cab is awesome...
