Passive 3D Displays vs. Active 3D Displays Will these make a difference with how 3D Vision will work
  6 / 8    
[quote="ramps"]So I read more about passive 3D. Am I right if I say passive 3D 1080p/60hz need same gpu power as 2D 1080p/60hz and active 3D 1080p/60hz need 1080p/120hz 2D gpu power? So passive 1080p needs 2x less gpu power than active 1080p, but passive only gives you 1920x540?[/quote] You've already asked and had this question answered twice in this thread.

I read other thread, there people said passive takes same gpu power like 2D but active takes 2x more, but here people told me that they both takes 2x more than 2D gpu power. I don't know what to believe. That's why I ask again, maybe I have misunderstanding because I'm not good with english.

Here I read that passive 3D only needs 2D gpu power http://forums.geforce.com/default/topic/818183/3d-vision/gtx-970-4k-3d-vision-gaming-success-with-lgub850v-passive-tv-/post/4506516/#4506516 [quote="innuendo1231b"] Simple 2D 3840x2160 @ 60hz signal is sent to the display, no 120hz and no 3D signal. The display does not have to do any processing of converting, it simply displays all the pixels as it would normally. [/quote]

He's simply saying that by sending a Line Interleaved format to his Display, it doesn't have to post process the incoming 3D Video Stream. Anything that is received by a Passive Display using a FPR screen that is not already in an Interleaved format "MUST BE" converted prior to being shown. His statement "Simple 2D" is erroneous, it is indeed receiving a 3D input. I think what he was trying to convey, is that he doesn't have to manually switch the TV into 3D Mode.

Sorry but I don't see logic in your text. If passive 3D use same GPU resource like active then how passive can use 2160p and not having bandwidth limitation what HDMI 2.0 have(max 2160p/60hz 2D)

Sorry for being curt, been a long week. If it clears it up for you I can upload a video tomorrow showing my fps cut by half when I turn on 3D. The 3D at 2D power would be awesome, I wish it was the case but unfortunately it ain't. I would definitely recommend active over passive, for the reasons I said earlier and also with a 120/144hz screen you get the bonus of playing 2D games at a higher refresh rate.

Ughh, Because half frames are sent, half frames do not require the same bandwith as full frames. You are comparing interlaced to progressive. 2160i is not the same as 2160P. Please GOOGLE it. I'm done answering

But still 3840x1080 x2 @ 60hz is over the hdmi 2.0 limit.

I have heard that active 3D removes motion blur in games? Is that true?

Your math is horribly flawed


It's 3840 x 1080 = X

X x 2 = the result

It IS NOT 3840 x 2 + 1080 X 2 = the result
