HDMI "no signal" issue and weird fix

[jgrn]

Ok, so I have read all about the no-signal issue with RPi and HDMI. I've done everything from:
hdmi_safe=1
to tweaking each of the hdmi settings individually (hdmi_ignore_edid=0xa5000080; hdmi_ignore_hotplug=1; hdmi_drive=2; hdmi_group; etc). I've yet to find a combination that works by simply letting me turn my Vizio HDTV on, and then powering up the RPi, and then it working right. What happens is the red and green lights come on and stay on, but the TV continues to say "No Signal" and the networking never starts up (so I can't access it via ssh).

Here's the weirdness, and it reminds me of the move those guys in nuclear war movies have to perform where they have to turn the keys at the exact same moment. If I set the input to the HDMI port directly before the RPi's port (e.g. if the RPi is on HDMI 3, I set the TV to HDMI 2), flip to that port (e.g. with my TV's remote) and QUICKLY turn the RPi on, I can get it to boot. The timing has to be perfect, otherwise I get the "No signal". If the RPi turns on before the TV switches to the proper HDMI input, no good. If the TV is already on the new input, and the RPi is then turned on, also no go.

Although I enjoy the challenge of getting the timing perfect, does this particular issues recommend any specific (but less common) config.txt settings? I've worked my way through most of the common settings...

Edit: I'm running the latest: 1.0 Beta 1. Re: cable, I doubt it, since I've been using that cable to plug my laptop into the same TV with zero problems. I've tried upping the boost to 4 and then 9.
