Left side of the screen missing (HDMI)

[bozza]

The left side of the screen is cut off when I boot a custom buildroot image that I have compiled.
The left side of the command line cannot be seen. I am not sure if this is just my tv or if it is the OS.

Raspbian displays just fine on the same tv.

Could anyone test the OS and see if it displays correctly?
The OS is a default buildroot build for the raspberry pi zero. It should work the same on any pi 1 though.

You can download the image here: https://mega.nz/#!aI1WFLYC!OOBiMbDerxEA ... A1nvp7iLnU
The image should be written to an SD card like any other OS.

Once booted it should say "welcome to buildroot". For me the only part that is visible is "e to buildroot".

edit: username is root
password is blank

Check your overscan settings in config.txt

Is there any reason why I would have to adjust overscan, when other images work just fine with the default config.txt?
