3D is not working

<< < (4/9) > >>

rec head:
If using Nvidia cards you can have MC output 3D as Top-Over-Bottom. At least with my TV, I need to then switch it manually.

Let's pump up those rookie numbers on the "I have the same question" button.

That user's fix was to rollback the Feature Update as well.

OP - can you confirm your Windows build?

JRiver, any chance of placing this on your watchlist?

I do and PowerDVD works. Seeing as though the version of madVR hasn't changed (.097) I consider this a JRiver MC issue even if that involves working around a Windows 10 (2004) bug\issue.

TheShoe:
This weekend I purchased an AMD 5500XT card and installed it into a new HTPC running a fresh install of Windows 10 v2004.

While Frame Packed 3D would trigger the TV to enter 3D mode, the video was clearly not 3D.  Worse, stopping video playback completely caused the system to become unstable - MC crash, the AMD drivers refuse to recognize the 5500 XT (displays an error message trying to start their management app) upon reboot, and Windows Device Manager reports both the integrated GPU and the 5500XT as "not working" with an error code (internet searches were not useful is resolving).  No amount of driver removal/re-install worked.  We had to basically rebuild Windows 10 from scratch.  We tried re-installing the drivers, removing the devices and re-installing the drivers, disable/enable the devices, nothing worked.  Each time Windows would simply load their "basic video card" support and show both the integrated GPU and AMD card as not working.  Something becomes corrupted in Windows at a basic level under this situation. 

We tested this twice - complete re-install of windows to get it all working again, using default AMD driver settings, attempt to playback frame-packed 3D - with the same results (thankfully re-installing Windows is not a terribly time consuming process). 

In any case, the simple "fix" for me is simply tell MadVR to output top-and-bottom and press a button on my remote to tell the TV to enter 3D mode, which is what I do with my other HTPC that is nVidia based.  Since it's a 4K OLED, it's still full resolution 3D and looks every bit as good as frame-packed.

If I can find a copy of Windows v1909 will test that next...

Shoe, I don't have a fix for your 3D problem, but I can give you some advice that will make your life easier.

This reinstalling of Windows is a needless torture you're inflicting on yourself. Get yourself a copy of Macrium Reflect. They have a free version.

Use it to make a backup of your C drive. Schedule it to keep making incremental or differential backups.  You will be able to use it to revert the computer to a working state, as if nothing had happened, in just a couple of minutes.

For example, I have my JRiver server booting from a SSD. Any time I make a change, like a Windows upgrade or an MC upgrade, or putting in a new version of madVR, I take a snapshot first.  If I don't like the results of the change, the time it takes to revert to the snapshot is about 70 seconds.  It's literally like nothing ever happened: the entire filesystem, registry, everything is back to the way it was before. You don't have to think about undoing what you did, or about any ill effects.

It's a lifesaver, so I highly recommend it.

Good luck...
