LG 47LH55 Calibration

 

Extended Notes on ISF Calibration: Calibration approach to the 10-point IRE setting. Using this LG feature, you are able to dial-in each point on the IRE scale. Although you have to make 10 separate adjustments, it provides full control over the IRE range and rework is not needed as much as you would get with using a traditional high-low 2-point setup.

Jaggies 1: Pass, excellent result
Jaggies 2: Good to Best

Noise Reduction: Film Detail Test Race Car in motion/Stadium Seating: Pass. There is a moire' pattern in the stadium seating for just .5 of a second before the internal processing of the LH55 cleans it up. The 120hz/240hz feature looks amazing with this race track motion test. It really puts you on the action.
