There are limitation on which the VGA output an DACs can work:

I/O GPIO pads are 0-19, 21-23, 25-27, 32-39 Input/Output GPIOs are 0-19, 21-23, 25-27, 32-33. GPIO pads 34-39 are input-only.

Beware of pin 0. It selects the boot mode. It can only be used as any of the syncs. (no resistors attached)

Pin 5 is often tied to the LED but can be used as hSync if you don't need the LED. I²C is on 21 (SDA), 22(SCL) DACs are 25, 26 ins 1(TX), 3(RX) sould only be used if really don't need to communicate anymore.

Here is an overview for your convenience: (0), 2, 4, (5), 12, 13, 14, 15, 16, 17, 18, 19, 21, 22, 23, 27, 32, 33
