[PROBLEM] Set HDMI resolution

[Meestor_X]

I'm sure it's in a doc somewhere, but I haven't found it yet...

How do I set the resolution on an attached HDMI monitor? raspi-config didn't seem to do it...

Got it, thank you.

There was some framebuffer_ crap in config.txt that I just deleted, then raspi-config worked!
