Viewing Effects Summary
Editorial Note: This is a review of the LG 47LH90. Test results are for this model, but should indicate the general performance of other sizes in the LH90 series. The LH90 series also includes the 42LH90 and the 55LH90. Read here for more details on series differences.
• Average viewing angle for an LCD.
• Screen diffuses incoming light well, resulting glow is quite large; bezel is a bit reflective.
• Testing done using DisplayMate Software
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.

R
eflectance (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.
| Setting | 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. |

Samsung UN32D5500 LED LCD HDTV Review
The D5500 has a rather high MSRP of $699, considering it’s only a 32-inch TV. There are some “premiums upgrades,” a term we use with some dubiousness, knowing that these features can be far less valuable than they appear. Nevertheless, at its core this is a good television. If you can find it a significantly reduced price it would make a great addition to a home theater. Read More...
