power cord affects on video?

Has it ever been discussed before if power cords can have an affect on video quality for example with bluray players and TVs? Some may use high end power cord on bluray players for audio, perhaps they could comment

I was experimenting with a high end CRT monitor and the power cord does indeed influence the picture, though since CRTs naturally have a soft image most of the benefits of the better cord are probably lost, conversely since CRTs are purely analogue devices and draw more power than LCDs they would benefit more than an LCD I assume.

a 4K LCD and 4k bluray would be a good way to test this.

That's how it is with all dogmatists.

Ah, the age old canard re: all that wire that come before the outlet.
Tell me now, who has an excitable imagination?

One can't argue with what one sees. That's one blessing that detractors have no influence on. With my old Samsung Plasma TV, I tried a Zu Mission PC that I had laying around and the black levels went deeper with more gradations and subtlety in the details. You could make out more image detail in the darkest of settings. 

PLUGE levels (greyscale) were much easier to discern and moire patterns were lessened a bit as well. 

All colors took on more saturation and intensity, contrast was more apparent and brightness levels increased some. It was like the TV was starving for more power.

All the best,
