PS3 Video Mode
From PS3 Wiki
The PS3 does not have a typical way of changing screen resolution as computers do, it has it's own process to do so
There are two options for each screen mode: fullscreen and blocked, for all extensive purposes blocked is a better option to try first, because with fullscreen the screen's resolution may be larger than the television's viewing area
Once set up as blocked, you can then try to use fullscreen. However, note that if you want to use fullscreen mode, your television must be capable of using the "full over scan."
Using ps3videomode
at the terminal, type in ps3videomode to display your current settings, or -h to display the following below
localhost ~ # ps3videomode -h Usage: ps3videomode [options] Options: --help, -h print this message --video, -v <ID> set video mode ID --full, -f use full screen mode --dither,-d use dither ON mode Video mode ID: 0:auto mode YUV 60Hz 1:480i 2:480p 3:720p 4:1080i 5:1080p YUV 50Hz 6:576i 7:576p 8:720p 9:1080i 10:1080p RGB 60Hz 33:480i 34:480p 35:720p 36:1080i 37:1080p RGB 50Hz 38:576i 39:576p 40:720p 41:1080i 42:1080p VESA 11:WXGA 12:SXGA 13:WUXGA full screen mode: <video mode ID> + 128 dither ON mode : <video mode ID> + 2048
Example:
ps3videomode -v 3 -f 720p 60Hz with full screen mode. ps3videomode -v 131 Same as above. If no arguments are given, ps3videomode displays the current video mode.
Don't use a different Hz setting than your own, as the colors may not be displayed correctly. Also, if using -f or +128 the screen may get "divided" into halves, so you need to go back to your default and instead, try editing the kboot.conf
Changing kboot.conf
Once you have decided on a setting, you should edit your video settings from /etc/kboot.conf
Change
video=ps3fb:mode:#
with your new number setting
Example:
video=ps3fb:mode:2177
will display 480i in fullscreen with dither
