I have the display adapter and a VGA cable running to my 8 year old HP Big screen TV. When I had Windows 8, sometimes the screeen would flash, then shift slightly (about 10%) to the left so that the left side of the screen was not visable and a black bar appeared on the right side. I used to fix this by simply refreshing the input to VGA. Since I have upgraded to W 10 the screen is not PERMANENTLY shifted to the left. When I change resolutions, I can get the whole screen on the TV but it is absurdly small and there are big black sidebars. NOBODY I have spoken to at MS has the slightest clue how to fix this. Thoughts?
