to see some movies and all I see is NO SIGNAL.With Vista it was ok and now NO SIGNAL.
I checked my laptop and it detects my Vizio tv and show 1 and 2 monitors but no output
signal.Nvidia shows two monitors but no output.Been searching with no results.I've seen
a lot of views to my post with no replies.It looks like no one knows about this problem.Need help.

The proper input is selected on the TV? DVI 1 or DVI 2, etc?

OK, on my setup my cable box is on HDMI 1 and my PC is connected to HDMI 2. I have to switch the source on the TV or I get a No Signal Detected. I'd have a look for the latest Video driver for your laptop if you haven't already.

Hi there

It's probably not as complicated as that -- a much more simple explanation is that the resolution you've set for the TV can't be displayed or the display settings on your laptop are too high for the TV.

The easy way is to set the laptop at something sensible -- most laptops do 768 X 1366 and have the TV at either 1080i or 720p resolution. If your TV was marked HD READY rather than full HD it won't be able to display a full 1080P output (1960 X 1080 or even higher).

Fortunately now all TV's are FULL HD but until quite recently a lot were on sale with the "HD READY" label -- I'll bet a lot bought these sets and are a bit miffed that they can't get FULL HD from NETFLIX, SKY etc etc.

You should be able to set the TV's display settings with the TV's remote.
