Trends in PC Displays

While some of the basic display trends certainly apply to PC displays--new aspect ratios, lower-power displays, and LED backlighting, for instance--other things are unique to desktop monitors and notebook displays.

The top five brands account for over half of all PC display sales. The top three, HP, Acer, and Dell, together account for over half of all notebook sales.

On the technology front for desktop monitors, 16:9 and 16:10 became the dominant aspect ratios in 2009, though large enterprises are still using older 5:4 and 4:3 aspect ratios. LED backlighting is in just a small percentage of the market (less than 10 percent) but increasing. Fast response time, better color saturation, and wide viewing angles are the technologies that monitor makers have focused on. 3D is just starting, with an emphasis on gaming. The average size of a desktop monitor is getting slightly bigger, but not by much.

Touch screens have grown in All-in-Ones* in part because they work well in retail environments, even if people don't use them all that much at home. But, many companies have pushed out their plans or made touch screens an option because of panel price increases towards the end of last years.

For notebooks, there has been an even faster transition to the 16:9 aspect ratio. LED backlights are now in over 70 percent of that market, because the display is a much smaller part of the cost of a notebook than it is of a monitor. The focus has been on glossy screens with reduced glare, and lower power consumption.

Glossy screens, have vibrant colors and the highest contrast and brightness because they have a smooth, high-gloss surface. As a result, it is often the choice for movies or gaming. However, strong lighting causes glare on these screens which is very annoying and may cause eye fatigue. You can also see reflections on the screen. Some graphics designers may also find the colors inaccurate. Glossy will work great for you if the lighting in your room doesn't create any glare on the screen. Matte screens don't get glare or reflections on them, however, suffer from less contrast and brightness.

On notebooks, the average size has actually gone down a little bit, partly because of the move to 16:9 displays and partly because of the move to "mini-notes" (which have stabilized at an average 10.1-inch screen).

Multifunction monitors are expected to be a growth area. They give home users the ability to browse the Internet or work on an e-mail while watching a baseball game in a small TV window–or just sitting back between tasks and toggling between channels on a full screen with a remote control. Business users can be working on a spreadsheet at the same time they keep up with stock fluctuations through CNN. These displays even offer additional video and audio hookups that enable the user to connect the monitors to devices such as DVD players and video game consoles. The most recent multifunction displays are also designed to work independently of the PC, meaning that TV functionality is available even when the computer is off. The list of features can get so extensive that multifunction monitors are good enough to replace full-featured LCD TVs for small room and office set ups.

Laptop sales were being driven by multi-PC households, with the market moving from one PC per household to one PC per person and the primary usage location for a home laptops has moved from the home office to the living room.

Netbooks might increase the trend to multiple PCs per person as people who buy netbooks for travel are also using larger laptops at home. The laptop market is now seeing diversification based on different size screens, with 18.4-in notebooks now selling to gamers, and with younger customers gravitating toward more portable machines than the traditional 15-inch size.

*All-in-one refers to a desktop computer that houses every component except the keyboard and mouse inside the same case as the monitor.
