“ The biggest disadvantage to this approach is that when you compress the left- and right-eye streams into a single HD image, you lose half the horizontal resolution, which falls from 1920 to 960, ” says Cheng. “ When the two streams are reconverted and overlaid, the sharpness of the image is noticeably less than that of 2D HD. But this is the best technique available right now. ”
「這種做法的最大缺點，是當左右眼訊號『塞』入同一個 HD 畫面時，畫面的橫向解析度會喪失一半，由 1920 降至 960；當左右眼的畫面經過解碼還原再疊合後，影像銳利度將比單一的 2D HD 畫面遜色，但已是現階段的最佳解決方式，」程智誼說。
