With regards to hardware base 3D, having upgraded to Jarvis RC1, i'm now find that instead of switching to 3D for full sbs 3840x1080, it's switching to 4K resolution (got a 4K Sony) instead. Obviously this shifts the resolution away from the required '1920 x 1080 (recommended 3D)' setting, so hardware based 3D doesn't kick in.

I'm using the *******.3d file name format for 3D ID.

I found this post about a possible cause... 2210879 (post)

fritsch mentions...

...maybe looks like 3840x1080 is also causing a switch [email protected] hz as its matching to 'width' 3840 as the only identifier, and not 'width+height'?

fritsch's change is great (many thanks fritsch Wink) if a 3840x2160 'width+height' resolution match is found, as it would enable both full sbs hardware based 3D and 4K, by allowing you to run the required desktop resolution setting '1920 x 1080 (recommended 3D)', and the ability to play 4K vids... hardware based 3D would obviously not be possible if you have to run desktop resolution at 3840x2160 to play 4K vids, as you would lose the required setting '1920 x 1080 (recommended 3D)'! Just that 3840x1080 resolution needs to be ignored for 4K switching!!

Here's a debug log... http://pastebin.com/i4dfcN9x

Many thanks

Hi afedchin,

I've just double checked everything... windows desktop resolution set to '1920 x 1080 (recommended 3D)'. Kodi preferred 3D mode set to hardware based.

I can switch the Kodi setting 'stereoscopic 3D mode / current' to hardware based, and the TV switches to 3D correctly.

However when starting 3840x1080 full sbs file, as per Fritsch's change, the TV switches to 4K 3840x2160.

Then using Kodi OSD, the only 3D options showing are sbs and tab, and auto. As the TV has switched to 3840x2160 resolution (as per Fritsch's change), I'm not sure hardware based would be an available option anyway, as the required setting '1920 x 1080 (recommended 3D)' for hardware based 3D is no longer active or set.

Here's a fresh debug log showing all the above... http://pastebin.com/nbzMYFWi ...hopefully you'll see the manual switch of 'stereoscopic 3D mode / current' Kodi setting to hardware based in there.

Many thanks
