It's not the TV and since Windows 7 just rolled out the new laptop has a warranty and the laptop has a flaw. Call it in before you are stuck with the issue.
I have a Sony Vaio laptop which is running Windows 7 professional, and a Samsung 37" LCD TV. I tried connecting the vaio laptop, via VGA to the tv but the tv isn't displaying "PC" under input. It seems to do something with my laptop because it makes a noise and it goes to display my background without icons or toolbar. If I ctrl+alt+delete my laptop screen turns black. With this problem I can't run the Intel TV Wizard or change my display settings in the control panel. Right clicking seems to make the laptop screen display its background only. I did download the latest driver from Intel, the Intel GMA X3100 driver.
I have a Dell laptop with same video card, ram, and cpu, but it works flawlessly when I connect it to the tv. I'm not sure what is wrong with my Sony laptop.
