Please attach hdmi.sh to your post and tell us what is the resolution of the monitor or TV you are using.

hdmi.sh reads the mode parameter in the command line and sets up the framebuffer accordingly.  The default is 1080p.

 

Please run the following command:

cat /proc/cmdline

 

and report the result here. Also please indicate what resolution(s) your monitor or TV is capable of.

19EL933G toshiba TV HD, but I have many TV toshiba, samsung, philips ... and I have the same problem with the display ( 1366x768  50Hz for the first toshiba)

[temps]

If I do :

                720p*)
                        export X=1360
                        export Y=768

 

I have a very beautiful image, but it is deported on the left, and I miss all the beginning of the lines of codes

[AndrewDB]

Either you try a proper HD TV or monitor capable of 1920x1080p, or you have to play around a little bit with the fbset command to try to find some setting that will work on your TV's.

Thanks, when I do

fbset --info

    geometry 1360 768 1360 768 32
    timings 0 0 0 0 0 0 0
    rgba 8/16,8/8,8/0,8/24
endmode

Frame buffer device information:

    XPanStep    : 1

Thanks for the answers.
I found a solution, by changing television.
The problem of the first TV is that there is no "native" mode in its settings. Taking another TV always a 19-inch toshiba, at first I had the same problem because it was in cinema mode. I corrected. I tested samsung which was no problem with the latest hdmi.sh
