Let me check what's resolution in default mister.ini file. Thank you.I typo'd on my earlier post about the mister.ini file. The default mister.ini file that is in place with a fresh MiSTer installation sets the resolution to 1280x720 (720p) which most displays support. If you don't get any display from your HDMI port at that resolution then I'd make sure the HDMI cable is tight and perhaps try a different cable. The 320x240 or 640x480 resolution is after you replace the default mister.ini file with one of the ones pre-made for the MiSTercade.
