I watch tv shows on my tv that I download from iplayer etc. I have a nvidia geforce 210 graphics card and I have set up extended desktops. I have my PC monitor as my main display and have dragged my media player to the tv. When I play them I get a couple of horizontal lines flickering about 1/2 the way up and 2/3rds the way up the screen.
It only happens when my monitor is main display, if I have my tv as main display it's fine, but then I can't use the pc properly.
I've installed new drivers and done a clean install of the drivers and I've changed the HDMI port and cable on the tv to no avail. I emailed Nvidia and they gave me the usual steps but none of them have worked.
The tv is a Panasonic TX-P42GT20B Plasma TV
If anyone could help, I'd be eternally grateful.
