Never failed but I discovered one estrange thing: moving the mouse (pointer presented on the screen) destroyed 3D image. Video continued in 2D. As soon as the mouse pointer is removed from the screen (because of inactivity) 3D mode returned properly. Funny isn't it.Going back to MP, I found that almost 100% of the times (almost...) Madvr detects 3D video DX11... bla, bla, properly but presents video in 2D.Here comes the nice thing. moving the mouse, a quick blink in 3D and... after disappearing mouse pointer, 3D back to screen normal. <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite12" alt="o_O" title="Er... what?    o_O" loading="lazy" data-shortname="o_O" />So 3D works in Nvidia but its affected by something (layers?).<img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite18" alt=":LOL:" title="Laugh    :LOL:" loading="lazy" data-shortname=":LOL:" />So IMO there is something wrong in the way info is presented.<img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite5" alt=":confused:" title="Confused    :confused:" loading="lazy" data-shortname=":confused:" />A deepest check of how the things go when 3D video is played in MP I found:3D video properly start (3D mode active on TV first).Very briefly I can see Madvr status in 3D (less 1/4 second).Then blank screen (madvr status disapears) for 2 seconds, then video appears BUT in 2D.Finally I need to move mouse on screen and, voila!Normal 3D.<img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite20" alt=":ROFLMAO:" title="ROFL    :ROFLMAO:" loading="lazy" data-shortname=":ROFLMAO:" />Tried on 114, and 109 Pre1.15 with LAV final 68.1 and git25EDIT-------I forgot 2 thigs.We have no 100% success just because if I play a 3D video after another 3D video, its highly probable to fail 3D mode (already described with intel HD4000 few days a go).You must wait for MP to release 3D mode.In MP-HC the release is only 1.5 secs. In MP the release is 6 secs. can we reduce this release time? Another discovery is that if video played without waiting for 3D mode release,  it will be played in 2D (with madvr 3D active)  and it can be recovered by manual activation of 3D in the TV. so the fact is that probably in this situation (wait time) 3D is lost because MP or Madvr sends a 2D mode to TV from previous video.In Exclusive mode, mouse movement doesn't affect a 3D and almost always 3D start properly.With MadVR "enable windowed overlay", 3D activation in TV and MadVr is very reliable (no 100%) but 3D will be presented in 2D untill mouse movement.D3D11 fullscreen windowed (3D) when no box click in Madvr General settings its the most failure friendly, even mouse movement will make madvr status in 3D but not the video.Thanks againA</blockquote>
