What parts to use to improve tv picture quality?
 

Besides power cords what other parts from any brand do you guys use to improve picture quality of your tv?

ADD-PWR products, see Banner below, and Manufacturers Forum here.

If you are really serious, talk to me about Lumagen Scalers.

I did 3 things for my projector installation :
- Shunyata SR-Z1 outlet
- Shunyata Defender
- Shunyata Venom V14 power cord

On a 106" screen, the Defender removed the fuzzy noise from the picture. The SR-Z1 and the Venom V14 improved the overall picture with better contrast and blacker blacks.
I would have like to install a better power cord but the socket of my projector (Panasonic PT-AE8000) won't allow any big slug to be inserted.
