Here is my issue.
Two phone calls to LG tech support and an LG tech visit later, they have no solution.
When using my PC via HDMI 1.4, Windows 7 desktop displays a nice bright contrast.
It is when I launch my browser, either Firefox or IE, that my screen goes to a medium grey.
If I minimize the browser and slide it to the left slowly, the contrast brightens automatically until it reaches the correct contrast, this includes my desktop screen as well!
I even tried using just the Smart TV option so I could eliminate the HDMI cable. It turns out, when the google browser launches, it does the same darn thing!
Sometimes when the google browser loads slow, the html window is bright white and then bam, goes medium grey when fully loaded.
The LG Tech has no answer as to why the tv does this.
My LG LCD and Samsung LCD never did this.
Is it a plasma issue?
Please help, it is like someone rolled tint on my tv.
