Upscaling and downmixing questions

[DrieHarry]

Im pretty new with these shaders thing, im just have basic configuration from here
But if im usually only playing 2160p/1080p movie/anime on 1080 display, i dont need to use the shaders upscaling profile right?

Yes, you only need upscalers if you're watching video's that have a resolution lower than your display.

Got it thanks for your config, i have another question but confused how to explain it xd (english is not my main languange) found something when i try to custom your config to downmix 5.1 surround to stereo myself,
Im not a sound guy so im probably wrong about this xd, but maybe theres a different with 5.1 format of DD E-AC3/AC3 and AAC surround, where AAC format used BR and BL channel and E-AC3 used SR and SL (surround left and right),
Your profile is works for AAC format which used BR and BL channel but it seems its not work (maybe) for AC3 that used SR and SL channel.
Ive tested it with sample video with AAC format and all sound is downmixed perfectly, but its not the case for E-AC3/AC3 format wheres only FL, FR, LFE, Center sound that comes out, it will work by editing BR and BL to SR and SL
If this is the case is there someway to edit the condition profile to read the format instead?

Sorry for my bad english (im using google translate) and again im probably wrong

Oh thanks for pointing out this bug, could you open an issue for it before we discuss things further?
