Locate the adjustment buttons on your TV and AVR remote controls and then follow the THX app tutorials which walk you through your “THX tune-up.” The app offers tips about your remote control, room lighting, viewing distance and other helpful advice. 
 
Video adjustments
• Aspect ratio – ensure your TV displays shapes & sizes correctly
• Brightness – make certain shadow details & night scenes are clearly visible
• Contrast – confirm white detail is distinct on your television
• Color – make sure colors are bright & vibrant but not cartoonish
• Tint – check skin tones look natural & are not too green or red
 
THX tune-up uses your iOS device’s camera to set color and tint with a special built in color filter. Point the device camera at the TV screen and see if the color or tint is adjusted correctly.
 
Audio adjustments
• Speaker assignment – ensure speakers are connected to the correct AVR output & intended sound is coming from the correct speaker
• Speaker phase – confirm that positive & negative speaker wires are connected correctly and all speakers are in phase
 
Extras
• Turn “moo can” on & tilt your device to hear it “moo”
