Just had my Toshiba 51HX83 today. Did some initial adjustments with AVIA Disk. Adjusted Convergency as well. I'm finding the picture a bit grainy. Is this because the TV hasn't been broken in yet? Will the picture quality get better later on? What are the steps I should take now and down the road in order to get better picture quality (Short of hiring an ISF calibrator)? Thanks guys!
