Hi, I have a Dell Inspiron laptop that is having some issues with HDMI connection. For about a year i have been connecting the laptop to my Sanyo LCD TV via HDMI and have had no issues. The laptop has always connected to the TV instantly, without requiring me to change any setting or manually use the Fn+F1 key to duplicate the image. Recently my laptop/TV have begun to stop allowing this. When I plug the Dell into the TV the laptop screen goes black for a moment, as it always has in the past before connecting, but then my TV displays a "no signal" message, and the laptop stops recognizing the connection. I have tried flipping through my TV's input settings and checking HDMI 1, 2 and 3, and turning on the TV and laptop in various orders without any luck. I have also used the Fn+F1 keys to switch from duplicate, to extend, to projector only. When choosing extend, the size of the display on the laptop changes, but the TV still does not receive signal, duplicate shows no change in laptop or TV, and projector only causes the laptop to go black for a moment, but then it comes back on with a message stating "no projector found." I believe that this may be an issue with the Sanyo TV, as recently I took my HDMI cord and used it to connect my laptop to an Emerson TV in my house, and it worked perfectly. I assume because of this I can rule out the possibility of the hdmi cord being the issue, or the laptops motherboard being the cause. I use this my TV and Laptop in conjunction a lot for streaming movies and playing music, and desperately need help! Any assistance is greatly appreciated. Thanks!
