Cons

LCDs

• Black-level performance. The best LCD monitors have only achieved a contrast ratio of 1000:1 (Connor 2009). Since LCDs shine a constant light through the screen to produce picture, a deep black is difficult to gain, and often requires much more energy.
• Viewing angle limit, defined when the contrast ratio reaches 10:1. Weber (2004) confirms that certain LCD monitors have a viewing angle of 170 degrees when applying this limit definition, yet contends that the quality of the image at this angle is not appropriate for high definition viewing. Weber proceeded to apply the PDP viewing angle limit definition of one-third luminance to the LCD monitor and reported loss of quality at 122 degrees horizontally and 91 degrees vertically (2004). This basically means that the further off center you get from the LCD monitor, the poorer the image quality gets.
• Motion blur. LCD monitors have reported showing lag when displaying fast-paced images.

PDPs

• Burn-in impact. Particularly older models have been known to have issues with faint “ghost” images that in effect "burn" into the screen. Plasma screens are at risk from TV logos, news tickers, and video gaming (Consumer Reports 2008). New technology has been development to combat this vulnerability, including screen savers and increased phosphor material quality.
• Inefficient consumption of power. According to Consumer Reports (2008), the larger the screen size, the more pixels contained, and the greater the use of energy. In fact, plasma screens use the most energy when producing bright white images (Connor 2009).
• Prone to glare, because most sets have a glossy glass screen.
