Our new 4K system and calibration

Where am I "coming from"?

I'm from Champaign IL in Concast land, at $200 per month ... but not for much longer.

I'm simply reporting the horrendous quality of our service. There are NO
channels I subscribe to ("140 channels") that are acceptable
quality. None at any resolution. Every channel except the lowest res
ones has pixelization on fast action. The so-called HD ones
appear to have maybe 1200 pixels resolution on sharp edges. On flat areas
like faces its much lower ... say 200 across the screen at 5, not 8 bits.
This is called "pasty faces". One can see MPEG wiggles around every
sharp line. On some talking head shows I see not 60 or 30 Hz refresh but rather 4 Hz for the background. You can see the horrendous low-bit
MPEG background squares change at that rate and no faster!

Our local over the air stations all have one so-called HD channel
and three SD ones. The HD shows all the same problems as Comcast,
just not as bad.

Edit: I just rechecked. Out local PBS station, WILL, is currently refreshing the middle background
MPEG squares (at most 4 colors per square, vertical or horizontal gradient only) at 1Hz.
They are constant for a whole second.
