Question xrandr to fix overscan on my TV connected over Displaylink from my Ubuntu device

Hi all,

I have a TV connected to my DisplayLink device, presented as DVI-I-2-1.

Whenever the TV goes into Standby mode, it forgets that it's been configured to display in "Full" rather than "16:9", and I suddenly (and consistently) lose 38 pixels to the left, 40 pixels to the right and 22 pixels at the top and bottom of the screen.

I've found that xrandr should help me fix this, but every incantation of xrandr I perform fails to solve my issue.

I suspect I need to use
Code:
xrandr --output DVI-I-2-1 --transform
but for the life of me, I can't work out the A,B,C,D,E,F,G,H or I

Can anyone help?
