HowTo: Fullscreen on a 1080p HDTV

I am sure that if you own a 1080p HDTV you have noticed the black borders around the edges of your desktop. You may have tried the fullscreen mode via the ps3videomode command and then experienced a desktop that was a little too large for your screen. Well ... this is a guide that will enable you to use 100% of your real estate effectively.

First, you will have to make sure that your TV settings are setup correctly. You will have to enable the "full overscan" mode on your TV for the PS3 input. You can find this option on the TV's setup menus. (the option was Settings>Screen>Display Area>Full Pixel on my Sony HDTV)

Now for the fun part ... editing some config files. First we need to edit the /etc/kboot file so that it will use fullscreen mode.

$ sudo cp /etc/kboot.conf /etc/kboot.conf.backup
$ sudo nano /etc/kboot.conf

You should see something like this. Change the video mode to 133. (it most likely is currently set as 5 if you have a 1080p TV) You can just erase the whole file and cut and paste this in there if you want.

default=ubuntu
timeout=10
root=/dev/sda3

ubuntu="/boot/vmlinux initrd=/boot/initrd.img video=ps3fb:mode:133"

Save and Exit.

Now we will have to edit our /etc/X11/xorg.conf file. We need to take out the optioonal resolutions so that the resolution will only be governed by the kboot.conf

$ sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf.backup
$ sudo nano /etc/X11/xorg.conf

Scroll down to the "Screen" section and find the "Display" subsection that corresponds to the depth of 24 and delete the "Modes" line.

The "Screen" section should now look like this ... (if you used the original xorg.conf from the tutorial ... if you didn't, I will assume that you can figue this out)

Section "Screen"
        Identifier      "Default Screen"
        Device          "Generic Video Card"
        Monitor         "Generic Monitor"
        DefaultDepth    24
        DefaultFbBpp    32


        SubSection "Display"
                Depth           24
                FbBpp           32
        EndSubSection

        SubSection "Display"
                Depth           15
                Modes           "1024x720" "1024x768" "800x600" "640x480"
        EndSubSection

        SubSection "Display"
                Depth           16
                Modes           "576x384" "1024x768" "800x600" "640x480"
        EndSubSection
EndSection

Now we can reboot just to see if it will all come together automagically.
Code:

$ sudo reboot

Enjoy the extra large desktop!

good thing i didnt try it then.. i have a 1080i display

can we edit the above tutorial to possibly get a full screen 720p resolution?

This will work for any TV that you can enable the overscan for in the menu on the TV. You need to replace the ps3videomode with the number that matches your resolution.

Here is a chart.
Video mode ID:
0:automode
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

To restore the backup of xorg.conf that you made ... issue the following commands in the terminal

It may be a good idea to make sure that you have a backup file first. Use this command and make sure you see a kboot.conf.backup there $ ls -al /etc/

$ sudo rm /etc/kboot.conf 
$ sudo mv /etc/kboot.conf.backup /etc/kboot.conf

You may not need the sudo depending on what distro you are using ... just issue the commands as root user.

Don't we want to disable overscan on our 1080p TVs so that we can display a full 1920x1080 image?

I have a Sony Pearl projector and I have overscan turned off as I don't want the Pearl to scale everything I sent it up by 5%. I want 1:1 pixel mapping, which I what I get from my HTPC and well as my PS3 when playing Blu-ray movies.

So if I follow the steps listed on page one of this thread, will I end up with a 1920x1080 GUI?

[pgi947]

so how about on 1080i/720p sets? not 100% sure what display my YDL is set at, i just know its not 1080p (not supported on my tv). I get black padding on my display (its nothing drastic i must admit) just something i'd rather live without :-)

[wizz0]

Has anyone fixed the black padding on 1080i/720p sets?
