Hey,
I have a NANAO MS2931 in my blast city cab. I cannot get it to go into 31khz mode. I can play fine in 15khz mode fine and the osd shows that its in 15khz mode. When I send a 31khz signal to it, it does not switch to 31khz mode, the screen is jumbled and shifted and the osd says its still in 15khz mode. Any help would be appreciated as I have found very little info on this monitor.
Thanks
