I have a Dell Latitude E6540 and the main screen won't work, I have cleaned all connectors, replaced the cable and tried two new screens, external monitor works perfectly which has me confused.
Here is pictures of two brand new screens for this model, both doing different things, the original screen was different also with a pink hue if it was tilted on 99% of angles (It would go away if put on just the right angle)
