Can I keep Live View from going into standby after about 30 minutes on a 7D?

Hello,
I'm doing live visuals, capturing a live HDMI stream from my 7D running Live View at the moment. Can I keep the Live View alive at all times with Magic Lantern? It's turning live view off after about 30 minutes or so, going into standby. All I have to do is to fiddle around with some settings now and then, like.. change the aperture up and down a notch, to keep it alive. But it would be great with a setting to keep the Live View alive at all times. Have I missed it? Running Alpha 2.
I already turned off the auto-power-off feature in the EOS settings, and I'm running it on external power.

Thanks in advance.
