To remove black bar, you can do it with “Crop”, and it has nothing to do with “Resize”.
For cropped content, you can choose one output resolution from the resolution list, from large to small. We can call it “simple resize”.
Sometimes the aspect radio of cropped content doesn’t match with device aspect radio, so we need use “Advanced Resolution Settings” to adjust how we fit the cropped content onto the device.
For generic, there is no device aspect radio, which means any resolution can be played on PC, so there is no need to use “Advanced Resolution Settings” for generic mode.
