Down 1x (off autodetect, onto 720 resolution)
Wait 5 seconds (applying)
Thank you for posting this, I confirmed it and posted it elsewhere where it was being asked about. That down 4x is the key for Ultra. I also failed a few times not understanding that after waiting 5 seconds I'd need to press OK one more time while still blind...after that very last OK (and a few seconds) is when something should finally be visible. Roku needs to make a default fix for this.
