I have a Lenovo Ideapad Y650 running Windows 7. I currently have it connected to an Envision L19w698 LCD TV. VGA works fine. However, I want to use HDMI. HDMI is very blurry and only allows me to use 1024 x 768 (1440 x 900 creates overscan). I have the driver on my computer for the Envision monitor, but whenever i try to tell Windows to update the driver, it tells me Generic Pnp is the best choice. What should I do?
