I would download the MP4 version of AVSHD709
on your computer, take the black clipping test pattern (it's in the basic setup folder) and put it on a USB stick. Play it on your TV's built in media player via USB and see if his brightness setting is right. Obviously make sure that his calibration settings are plugged in when you're on the media player. Alternatively you can burn the AVC or HDMV versions to a DVDR/BDR and play it in your Blu-Ray player. You'll want to set the brightness so that 16 blends to black and 17 is barely visible.
If it's wrong, I would call them back and tell them that the levels were not matched to your display and make them redo the calibration. You can have nice looking results on calibration reports, but if the levels were not matched during calibration, the picture will be off for when the levels do
match (as they should).Edited by rahzel - 10/3/13 at 6:24pm
