On the other hand, passive 3D TVs deliver lower resolution. On a 1080p TV (1,920x1,080-pixel resolution), each eye is only seeing 1,920x540 pixels due to the polarized lenses blocking half the lines. If your screen is big, or you're sitting close, you're going to see what look like alternating horizontal lines, as in black lines in between the active image (see images below). Even if those aren't visible, the jagged diagonal lines they cause might be.
The benefits of 4K resolution are obvious...with passive 3DAt CNET we've spent a lot of time looking for appreciable benefits of 4K-resolution TVs, and so far we've come up pretty much empty. It bears repeating: With video on a TV, the difference between 4K/UHD and 1080p/HD resolution is really hard to see. In our tests of 4K TVs so far, despite all the extra pixels I knew made up the 4K TV's screen, most of the time I didn't see any difference at all, especially with HD TV shows and Blu-rays. 2b1af7f3a8
