Samsung Unveils Low-Power, USB-Only LCD Monitor – Say Watt?

By 2011, electronics maker Samsung intends to be mass-distributing its shiny new toy - an 18.5" computer monitor than can run off of no more than two USB computer ports and uses only 6.3 watts of power.

In an age where technology consumers demand that their peripherals not only function at high levels but also do the least damage to the environment and run as efficiently as possible, building a better monitor only made sense.

Using a backlit LED display and with a plan to wire in only two USB 2.0 cables, the engineers at Samsung went ahead and created a monitor with a native resolution of 1366 x 768, a contrast ratio of 1000:1 and a luminescence of 250 cd/m2. In essence, a middle of the road monitor in terms of specs, but with a far smaller power footprint.

This smaller power draw has apparently been accomplished by the use of higher efficiency LEDs for the backlighting of the display, although this has resulted in a 30,000 hours of use rating, down from the typical 50,000 hours found in a standard LED backlit monitor. The rate of transmittance of the panel was also increased, but Samsung has declined to offer any specifics on exactly how.

Certainly, the monitor carries with it some potential issues, such as a relatively low luminescence rating and resolution that make it less than ideal for some computer-based applications. As well, the potential for a lower life expectancy and the additional power draw coming off of the computer itself are a concern. CPUs and GPUs already draw far more power from desktop systems than they did even five years ago, and while the power draw on the monitor is low, it is one more drop in the bucket of PC-powered devices.

Overall, the monitor appears to be poised to be a rousing success, if its reception at the 2010 SID event was any indication, and Samsung stands poised to capture a new corner of the expanding LCD monitor market.

Also, the monitor represents one less power cord underneath the standard computer geek's desk. Any thing that carries with it less chance of a hellish house fire has to be a good thing, right?
