I have a Pioneer 533 53" RPTV calibrated by our own Gregg Loewen. Despite some initial electronic problems, once the set was sorted out and then tweaked by Gregg, I have been enjoying the set a great deal. However, there is one thing I've slowly noticed that I don't remember seeing discussed elsewhere... When there is a patch of light on a dark/black background (like the disembodied heads at the start of Zardoz, or the highlighted figures on the new Chicago disc) then often a vague circle of light can be seen around the bright light source. I guess it would be about an 18" radius if it was a complete circle. The center of the "circle" is always the strong light source. Is this something I can adjust my setting to diminish, or is it an accepted consequence of RP? Given how fussy we are, I'm surprised I haven't read about this one before. All comments most welcome!
