Laptop to Samsung TV HDMI Issues

by Th3irdEye / July 8, 2010 12:01 PM PDT

So I have been using my TV as my monitor to watch movies and play games for about a year now. Then my friend comes over and we wanna watch something on the big screen in the other room. That works fine as well. He leaves and I go back to my TV and I can't get the HDMI signal to work. No picture shows up. Just a "check signal cable" message.

So far i have tried two different HDMI cables, both of which i have confirmed to be working on the offending TV with my PS3. I have updated my video driver. I have tried all sorts of different resolution settings. I have taken my laptop and hooked it up to another display via HDMI and it works. I have taken my brothers laptop which is almost identical to mine (both gateway, look exactly the same except mine is a p-6831fx and his is a slightly different model number) and hooked it up to my TV and that works too. So basically:

my TV + not my laptop = works

my laptop + not my TV = works

My TV + my laptop = not works

I just don't understand what could be wrong. Especially since it has worked flawlessly for such a long time. Any ideas or maybe a setting I am missing?

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
