I just bought a big 'ol LCD TV today and an HDMI cable to hook it to my laptop. It set up just fine, I get a duplicate desktop on my TV and it looks awesome when I play games on it Interesting issue came up when I turned my TV off, it shut my computer down as well! I'm using a Toshiba Satellite, less than a year old. Windows 7 Home Premium with an ATI Radeon Mobility 4500 graphics card. I looked around through the ATI control program and haven't found anything relating to this. I'll keep snooping around, but any information would be great, thanks guys.
