MSI A6200 206US HDMI Problem

This is a new laptop with Windows 7. I was displaying on my TV set through HDMI but it stopped working.

I set the TV set to HDMI input and then select the Fn+F2 to toggle to HDMI but nothing. I tryed the Display Setting screen but it does not detect another display.

I suspected that some drivers were updated and was causing the problem so I reinstalled from the DVD all the Intel drivers.

What steps do I take to troubleshoot this problem?

 

Here is some additional information. When I bring the laptop up from sleep mode and the TV is on in HDMI input, the "Resuming Windows" displays on the TV set and then goes away and appears on the laptop. After that the Fn+F2 does not switch displays.

One thing I know I did install after it was initially working was the free Avast Anti-Virus. This does startup with the computer and may be interferring.

I could sure use some help and feedback.

 

You may as well give that a try, Avast could be blocking the outgoing connection for god knows what reason. End the program / kill the process upon startup, then see what happens.

Other than, my MSI swaps right to the HDTV display when the HDMI cable is plugged in, no Fn+F2 involved, so my situation is a little different.

 

First I removed Avast as a startup and the HDMI worked for a while until I did a Fn+F2 then it stopped. I finally uninstalled Avast and everything works.
