When the NAS first powers on the display in JetkVM is perfect, showing the QNAP system booting image. It looks to be about 1080p. Once the NAS has finished booting the display switches to what seems like a much lower resolution which is scrambled.

Although I could probably install QNAP's HD Station apps and customise the display output, I would like to know how to configure the JetKVM to display this default low resolution mode correctly. Is there an official guide on how to setup the custom 'EDID File' feature? I haven't yet found anything.
