How to set KODIbuntu installer to 1366 x 768 resolution?

[lachmacn]

I'm trying to install KODIbuntu on my media centre. I've loaded the ISO onto a USB stick with Unetbootin on Mac.

The problem I'm having is that the very old TV I'm using only supports 1366 x 768 resolution, so I think the installer is running but I can't see a picture.

Is there a way I can configure the installer to start with a resolution of 1366 x 768 so I can see it on my TV?

After digging around some more in menus for the receive I think what I said is wrong anyway. It seems like it's more something to do with my PC not outputting HDMI to the receiver (at least not in a format it's recognising) because the TV is receiving a 576p signal from my receiver (I can see the menu from the receiver). So ignore this question sorry...
