PsychoPy + LSL + LabRecorder – EEG looks different from BrainVision

Hi,

I’m using PsychoPy with LSL triggers and recording EEG via LabRecorder.

Compared to BrainVision Recorder, the EEG looks noisier and has larger amplitudes.

Is this expected (e.g., due to no online filtering)? Are LSL triggers reliable for ERP timing? Anything important I should check?

Thanks!
