but I mean is it a true 1:1 mapping, no lanczos sharpening or anything if the scaler is not enabled? like playing 720p in 1280*768
I find your questions very confusing. First you say you have a test pattern to test 1:1 mapping. Then you ask me if you have 1:1 mapping. Why don't you test it with the test pattern?

Then you ask me if you get 1:1 mapping when playing 720p in 1280x768? How am I supposed to know how your media player is configured? madVR does what the media player asks it to do in terms of scaling. Of course if the media player asks for playback in 1280x720 with a 1280x720 source then madVR does simple 1:1 with no scaling and no sharpening. If the media player asks madVR to scale a 1280x720 source to 1280x768 then madVR does scale, but only in Y direction. Sharpening is currently not applied by madVR at all. There are just softer and sharper scaling algorithms available for selection, which of course are only used if scaling is asked for by the media player...
