1.4l DUAL 1080p 3D image
1.3:
Like most things though, the 3D update for already existing HDMI 1.3 products comes with a catch, and it’s a catch in the form of reduced video quality. While HDMI 1.4 cables and devices will be capable of shooting out 3D pictures in full 1080p, HDMI 1.3 just can’t handle it.
The problem is that for a 3D picture, two images have to be shown nearly simultaneously. Since HDMI 1.3 can’t handle two 1080p pictures at that speed, you’ll get two 1080i pictures. It’s not a huge downgrade when all is said and done. The real clincher comes with TV signals.
Since cable boxes normally show a 1080i image, they’ll be stepped down to 540i to handle 3D. With HDMI 1.3 cable boxes, you’ll have the choice between HD and 3D, but not both. |
