Hi I have a problem, I am trying to force this into 720p and have no idea how. I know my HDTV Supports it as it plays nearly all PS3 games if not all in that resolution. I have put in the display settings to say 720p is max support in my PS3 Settings but it always goes into 1080i no matter what and everything is so tiny i can't see anything. I have to move right up to the TV to see whats what.
Any suggestions would be great. I have also looked into the display resolutions in Ubuntu but i can't change it from default.
Open up a terminal and type:
sudo /etc/init.d/gdm stop this will stop the graphical interface and display a black screen with some writing on.
type:
ps3videomode -h it will give you back a list of resolutions that looks like this:
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
dither=2048 or -d fullscreen=128 or -f check the list for your resolution so in your case, 720p is either number 3,8,35 or 40.
you can then add 128 to that number to give you fullscreen so for example, i'll use rgb 60hz so 720p is 35 ill add 128 which is 163.
so 163 is 720p fullscreen.
now type:
ps3videomode -v X (replace X with the number you are using)
now to test it, start up the graphical interface again,type:
sudo /etc/init.d/gdm start
if the resolution isn't right then start again and try a different setting from the list.
if it is right then its time to set it so that linux loads that resolution on startup.
open a terminal and type:
sudo nano /etc/event.id/ps3videomode add this to the file just opened:
start on run level 2
exec /usr/bin/ps3videomode -v X (replace X for number)
Exit with Alt-X, save: yes, confirm filename
reboot linux and it should automatically boot into the correct resolution.
