I hooke my VGA directly to my cocktail arcade monitor directly with a torn up VGA cable. You don't really need the circuit of course except to protect the mointor before powerstrip sets the mode upon startup. To avoid building such a circuit for monitor protection you could use a jpac (has a built in monitor protection circuit), setup a start up sound to warn you of when it is safe to turn on the monitor, or build a power sequencer circuit instead.
One drawback of the last option is that the power would come on after a specified amount of time whether or not your system is fully ready with powerstrip on, as in a boot failure.
A fourth option I saw somewhere is to build a parallel prot trigger (or maybe some other port) that will activate your monitor on relay when the system has booted into the os (whereby your safe resuolution is set.)
