The main difficulty with real-time fMRI (Neurofeedback) is that display settings are not stable and it requires a lot of time to set them proper way. However, sometimes this also does not work.
The suggested solution is to make the properties of both video outputs the same (same resolution) so that the monitors can also work in a "dual" modus.
For this purpose a new monitor that supports the same resolution as BOLD screen has to be acquired
The monitor was purchased and installed on 9.11.2015. The settings were successfully checked.
