Bringing back a very old question....

Anyone upgraded their display devices power cord, be it plasma, LCD, LED-LCD, projectors or CRT ?

As most centered the upgrade for Power Cord in audio related devices ie AVR, CD-player, BR-Player, Amplifiers or Subwoofer, just curious anyone actually make it upon their display devices and does it benefit from such?

As our "Home Entertainment" comprises of both Video(Display) and Audio(Sound) do it make sense that the upgrade only centralised upon the Audio Section while seem the Video Section seem neglected. Of course most would say, we start the upgratidis on the source component and improve along the chain, but the video chain seem neglected while priority seem to be given to the audio chain. So any views? Is Audio take precedent over Video?

I believe some of us are running display devices (projectors, tv and such) that are of the expensive kind. Money are spent on better inter-connect, surge-protection and such, but do we leave the power cord out of this upgrade?
In the source and audio section, we upgrade the power cord along with the inter-connects but why we leave out that one link in the display devices?
As "some" of us do "hear" difference on audio, do the same "difference" can be obtained with power-cord upgrade on display devices? That is the question remains when upgraditis strike, do we upgrade "that" display power cord?
