Even though my TV was off, it still is seen by my other devices (PC, Xbox) so the Pi should have been able to see it as well and I shouldn't need to turn it on before the Pi.
The Pi reads the TV's edid on boot, to determine the resolutions supported. TV's should provide their edid when powered off (the Pi provides the 5V signal to power the edid rom) but they don't all support this.
If you always connect to the same TV, you can download the edid to sdcard:
sudo tvservice -d /boot/edid.dat
and add:
hdmi_edid_file=1
hdmi_force_hotplug=1
(and remove hdmi_group/hmdi_mode). Now the pi will read the TV's edid from the file, and it should behaves the same as it does when TV is powered on.
sdtv_aspect/sdtv have no effect on hdmi, so can be removed.
