That is interesting indeed... that's perhaps the polar opposite of what was being experienced before- it looks like it's setting a higher resolution but the firmware isn't actually putting it into the higher resolution. The firmware then lies to us about what resolution it's actually in, so we tell the kernel the wrong thing. You should be able to confirm this, as I recall, by bumping into the loader prompt and inspecting the output of `gop get`. That should report a higher resolution than it's actually in. > https://youtu.be/tlmaVJ-3aq0 > > (The rock sound track is just free audio to mask a barking dog and a radio > in the background.) > This was a most enjoyable soundtrack.
