Sorry I took a bit to respond, but my TV is by Dynex and it’s model name is DX-32L100A13. Aside from its firmware version being 568MS0002A5833, I couldn’t find any more info in regards to its specs. And I couldn’t really find a “PC mode” or anything of the sort; it’s really barebones in terms of features. It’s just a regular 1080p TV.
And yeah, I’ve tried it in 2x, 3x, and passthru, but none worked.
I can test the OSSC on my PC monitor, but I haven’t been able to do so yet because of the wire mess. Even then though I doubt it’s a problem with the OSSC considering that the sound works just fine, and that my TV is a pretty lackluster one to begin with.
