I just purchased an LG UK850 from Amazon and plugged it into my XPS 15. As you can see, there is a serious problem with screen flickering.
Is there any way I can diagnose this as a screen issue or graphics card issue with the laptop? I would hate to go through the hassle of having to do warranty claims and repackaging it and sending it back for a replacement, but at the same time.... this is pretty bad. Maybe I should just send this back.
It happens about every 10 minutes or so.
