CES: LG does passive 3D on monitors

LG has chosen the passive route as opposed to the active one taken by vendors such as Samsung and Nvidia. LG introduces the D42P monitor as its first passive 3D monitor.

LAS VEGAS--There are currently two competing 3D technologies vying for dominance in the home consumer market: passive 3D and active 3D.

Passive 3D is the less expensive option, using glasses that don't require power; however this solution is more susceptible to viewing-angle changes and requires strict head placement to continue the 3D effect.

The active 3D solution alternately shuts each lens of the glasses on and off so that each each eye is seeing a different image at all times, creating the 3D effect. This option is more expensive, as the glasses require their own power to function.

Both Samsung and Nvidia use active 3D technology for their 3D products; LG is taking the passive 3D approach with its D42P series of 3D monitors. I'm definitely looking forward to comparing all three flavors of 3D on computer monitors.

Incoming specs:

  • 1,920x1,080 resolution
  • 5ms refresh rate
  • 5 million:1 contrast ratio
  • 250 cd/M2 brightness (125cd/M2 in 3D)
  • 2D to 3D conversion
  • VGA, DVI, HDMI 1.4 x 2

Look for more info in the coming months.
