Projector Power Cords

there is no way a power cord that is connecting hundreds of feet of regular copper to a few feet of regular copper inside the projector that then feeds a power supply is going to have any effect on the image of the projector.  placebo can help a lot tho, our brains are powerful. 

all of the power cords matter people dont realize that there is a lot more standard copper inside the unit after the iec connector, then a power supply full of standard parts then many more feet of copper traces running the internal power around the unit.  Ive helped design and build many pieces of high end electronics and theres never been one I have seen that was built any other way.
