I'm going to be looking to sell my desktop very soon to offset some costs of my new computer. I'm going to just use my 12" Powerbook G4 for browsing and stuff until I get my new computer built. So I got a Mini-DVI to VGA adapter to use and hooked it up to my TX-42. Everything works great, it detected the resolution, identified it, and allowed me to set it as the primary display without problem.

However, I get intermittent interference (due to me running at 1920x1080). Sometimes the picture is clear and others there's faint waves or lines making their way through the image. I'm just using a cheap VGA cable that was included with a monitor, so I'm sure that doesn't help. I don't have the money to buy a shielded cable so what are some measures I can take to reduce interference? What usually causes it? Other cables typically, right? I considered wrapping it in aluminum foil, as goofy as it would l would have to think it would work, isn't that all shielded cables are basically?

Thanks.
 
How long is the cable? Is the TV 1080i or 1080p? What refresh rate? Does the macbook have an HDTV-out option?
 
The cable's 6 feet, the monitor runs at 1080p, 60hz like most LCDs, and although there's no HDTV option I'm aware of, I can select 1920x1080 no problem and treat the TV as a monitor, which is what I do in Windows.
 
Monoprice has thick VGA cables with ferrites to reduce interference for under $10.
 
It might be the adapter. If you have a 2nd one then try that
 
I have a Sony FW900 24inch Crt, I have the same problem, It might be the high rez with the higher bandwich having a higher chance to electronic interference. I did notice putting it on the floor took the problem away so something else must be causing it. It could be the adapter since there is no proper way to shield it. Oh well, don't know what to do, and I tried different cables.
 
Make sure that your power plug is grounded and get a better cable as suggested above.

I have a Sony GDM-F520 and I do not have this problem even at hi resolutions.
