Ok, I just discovered the wonderful world of "config.txt", thanks to my shiny new Pi User's Guide from Eben and Gareth. My Pi was not discovering the HDMI consistently so I found the solution in the book. The problem, however, is that I can't get the settings to work consistently. My monitor likes 1366 by 768 at 60Hz. If I set hdmi_group=2 and hdmi_mode=86 it should work. But, nooooo. What I get is a default of probably 640 by 480. If I set hdmi_mode=16 I do indeed get 1024 by 768. Higher resolutions than that seem to default back to the low resolution output. But wait, there's more. If I comment out hdmi_group and hdmi_mode and just set framebuffer_width and framebuffer_height I can get the desired 1366 by 768. Any ideas why hdmi_group and hdmi_mode don't want to play nice?
