That's a function more of the video than the TV. The older HD videos have that. It can also be taken out by adjusting the settings.

Did I forgot to mention that I have the sets professionally calibrated when new (after one week or so of break-in) and then at least once a year??

A must if you want to enjoy ...

According to a local TV repairman, the best LCDs are Sharp, Panasonic and another I forget. Avoid Sony. In the stores, Panasonic looks like it has the best picture--the highest contrast ratio 3000/1.
Check out Consumers Report last month. They reviewed these TVs. Olevia rated highly for best value. Make sure the TV comes with an HD tuner.

Not really. It highlights a problem with the internal video scaler & the integrity of the power supply. As well as the integrity of the 'wall power' too. Almost any video display can be greatly improved with an external scaler. It's costly though. Ditto with good power conditionong.

A poor disk transfer cannot be improved.

For whom, the consumer or the repairman? ;)

I had this problem when I first got my plasma set. I talked to a techy at the company, and he told me what settings to use. I don't remember the details, but I haven't seen that ripple effect in years. It may be lessened with progressive scan, which I have, but I thought it had something to do with the early HD videos.
Also, maybe the HD tuner supplied by the cable company. Mine is a motorola.

It was a nearby outfit that services LCDs and plasmas. He said plasmas aren't as reliable as LCDs, and avoid the no-name LCDs.
He meant for the repairman.

For a second set, what is the consensus on a 720p set. They are considerably less expensive.
