Power Cords and TV
« on: August 27, 2018, 08:22:13 AM »
   If you have extra audio grade PC around put them on your TV, cable box, Blue Ray, etc. While we were testing new power cords my TWL HC were sitting there resting.
  On a lark installed all into components mentioned and to my surprise the picture improved dramatically. Blacker blacks, deeper color, better focused picture.
  Already had Ubers installed and Digibuss. HUGE boys huge.

I have changed power cords on my older Samsung LCD TV from 2006. Newer TVs from Sony and LG I've seen don't have the 3 prong IEC connectors. They the smaller ones. What I did was I changed the outlets the TVs are plugged into and I also had some small isolation transformers in between the TV and the upgraded outlet.

The IEC C7 plug is a problem for many people.  First of all it in not polarized.  That leaves the TV or whatever wondering what they will be fed power from in the context of power polarity. 

For sport: if you have an IEC C7 plug feeding your TV, first turn it over to change the incoming phase relationships with the TV PS.  One way will ALWAYS look better.

Pete (TWL) and I bothe build IEC C7 power cables.  Give one a try.  It will change your video experience for the better.  Just get the polarity correct.

IF you have your display device professionally calibrated, any picture upgrade tweeks you do are meaningless. Regardless whether the calibration is done before or after the tweeks are added, the calibrated picture will be exactly the same even tho the calibration settings themselves might change slightly.

So if you want to spend your money wisely, spend it on a professional calibration done by a qualified ISF technician.

Ah yes, that is true in the home of the unacknowledged public. But the fact remains the goal for a calibrated display device is to replicate the movie theater experience. The projectors in theaters have all been calibrated to ISF standards, there is a constant there, it's not made up to appease to the public's perception of a "subjectively pleasant" picture. Of course in the home, standards get thrown out the window. The good news is in the last 20 years or so since ISF calibration knowledge has become mainstream within the industry, most tv manufacturer's are calibrating their TV's so there is at least 1 viewing setting that has a closely calibrated gray scale. But as it is in audio with Bose, the TV buying public generally still think the brightest picture is the best picture. Damn lucky thing, that's not the case when you drop $10 to go to the movie theater. :D

For transparency, I have in the past cut tv power cords, installed IEC terminals and added costly power cords and did enjoy a perceived improvement. No argument there if that's what you're striving for.
