They have a great red, but green is still problematic -- too yellow.
If they get a wider-spectrum backlight, they could revive Quattron
and put some distance between the yellow and the green.

I've had very good luck with my UQ17U 70 inch set.
Sharp sent it as a replacement for a 2012 model that turned
itself off and on once in a while. This one has been a champ!

Just a guess -- the pre-set starting point may have shifted?
Try starting with a Dynamic setting and work from there.

Lately, I've noticed a lot of aliasing on close-up shots of herringbone fabrics, etc.
This must mean that my satellite picture now produces more

Definitely call Sharp! My set did random shut-offs for almost 2 years.
Sharp tried 3 times to repair it, and finally replaced it with a new

It is a strobe effect with the backlights.
