Since VGA hpd detection is done through RGB lines load detection and
nowadays often goes through a bridge to some digital interface, HPD
detection usually takes a while (up to a couple seconds).
Thus, it is not as relevant to stress it as many as 15 times.
This brings the toggle count down to 5 times, which makes the test run
a lot faster without really changing the outcome much.
