Viewing Angle (5.15)
As you get further away from sitting dead center, you'll actually be viewing a lower maximum contrast ratio. Typically, LCDs are far less forgiving than plasmas in this regard, and typically dip below 50% contrast within 40°. Plasmas often don't drop below this marker until you're sitting close to the 180° mark.
We measured the LG 47LH90's viewing angle at about 24°. This is a pretty shallow viewing angle, but it's about average for an LCD.
Reflectance (6.0)
For this test, we shine an array of LEDs at the display to see how it reacts to a strong external light. We found the 47LH90's screen diffused the light into a large glow on the screen. We could still see the individual points of light in the array, but a lot of the detail was lost. The only downside was the glow took up a large portion of the screen. We noticed the TV's large bezel tended to catch the light, but we didn't think it was particularly distracting.
Video Processing (1.0)
The LG 47LH90 has a handful of video processing features. None of them did anything particularly noteworthy, mainly because video processing features rarely do anything noteworthy.

Claimed Function |
Our Impression |
| Dynamic Contrast |
Adjusts the contrast to keep it at the best level according to the brightness of the screen. The picture is improved by making bright parts brighter and dark parts darker. |
Makes darks darker and brights brighter, which leads to a lot of lost details. |
| Noise Reduction |
Reduces screen noise without compromising video quality. |
It does reduce some incoming noise, but not a significant amount. |
| Edge Enhancer |
Show clearer and distinctive yet natural edges in the video.
|
This will either create crazy sharpness artifacts or do nothing noticeable, depending on what's onscreen. |
