I've never replaced a video cable, just screens and I'm not sure on this one, Acer p455 , perfect image but then getting theses black and white horizontal lines off/on, perfect on external, I tried reseating the connector, I don't really want to order a screen unless I know for sure. Anybody seen this on a acer? 
UPDATE: It was a bad LCD FYI
