LCD TV VGA problems....

Question

Hi All,
I've pretty much given up on getting my Mac Mini to display on my LCD TV (Goodmans GTVL20W7HD) via DVI, as seen here: http://discussions.apple.com/thread.jspa?threadID=739287&tstart=0
So, I thought I'd "fallback" to the VGA option. I know the VGA input on my TV works as I've used it with 3 different windows laptops and my old desktop pc. However, what seemed like a sensible exercise has left me with even more frustration. I get no picture!
The result is better than the DVI, the TV at least powers up and recognises that it is receiving a signal. However, I'm still faced with a black screen, with the occasional white flicker, as though its "trying" to display.
I've been through the instructions for the TV and setup a resolution and frequency that matches those in the manual. But it never gets any better than that.
I've even tried tweaking it with SwitchResX, but no better results. The "Export DDC" in SwitchResX produces the following:

Answer 1

Have you tried manually switching the video input on your TV to Digital DVI? I know that some monitors do not do this automatically and could possibly be the issue here...
e-mail me and let me know...I'm working on getting my Mini ready as an entertainment hub as well...
