LCD TVs, sold as flat-panel units, can sometimes suffer from picture quality limitations inherent in the LCD technology. Shoppers must compare displays to check for image issues.
Performance Limitations
The Home Cinema Guide states that LCD technology can limit the image quality of LCD flat-panel TV sets. Viewers seated at side angles, for instance, may not see as vivid an image as viewers seated in front of the screen. LCD backlighting can limit black levels, and a delay in pixel reaction can blur fast-moving shapes.
Evaluation
Because different flat-panel LCD TVs cope with the technology's limitations with varying success, shoppers should compare several models in the showroom. Careful scrutiny can reveal how well the TV's image holds up from extreme angles, while a fast-paced sports program can reveal signs of motion blur.
Alternatives
Plasma TVs enjoy wider viewing angles and better color fidelity than LCDs without suffering the issue of motion blur, though newer LCDs have vastly reduced the motion blur problem. Before choosing a plasma TV over an LCD TV, however, shoppers should consider that plasma TVs consume more electricity and can suffer from "burned-in" images, according to Cnet Australia.
