HDMI has no settable modes that I could find in the header. This utility will not prevent you from setting HDMI modes, but you do so at your own risk.

VGA Modes:

• 0 = 1680x1050
• 1 = 1440x900
• 2 = 1360x768
• 3 = 1280x1024
• 4 = 1024x768
• 5 = 800x600
• 6 = 640x480
• 7 = 1440x900 RB (not yet supported, according to header comments)
• 8 = 1680x1050 RB (not yet supported, according to header comments)
• 9 = 1920x1080 RB
• 10 = 1920x1080
• 11 = 1280x720

LCD Modes:
0-15 (brightness control)

• 0 = 480i
• 1 = 576i
• 2 = 480p
• 3 = 576p
• 4 = 720p x 50hz
• 5 = 720p x 60hz
• 6 = 1080i x 50hz
• 7 = 1080i x 60hz
• 8 = 1080p x 24hz
• 9 = 1080p x 50hz
• 10 = 1080p x 60hz
• 11 = PAL
• 12 = PAL SVIDEO
• 14 = NTSC
• 15 = NTSC SVIDEO
