There is a small grey "squigly line" on the screen of my Alienware 17 R4 about a quarter inch long. Not sure how long its been there as I just got the laptop in a trade. I love the laptop so far and dont regret the trade, just wonder if somebody can confirm if this is "dead pixel" issue or "stuck pixel" or what. I thought it was a smudge at first but after cleaning the screen its still there and its not a scratch.
Is there anything else I can do short of replacing the screen? I tried to running the "diagnostic" holding D while powering up but not sure how to read the results, it just did a quick screen test with multiple colors and then rebooted without showing any information.
I was also going to try unplugging the ribbon cable for the screen and plug it back in and see if that helps, does the front panel around the screen frame just pop out like other dell laptops(like the dell G3/G5/G7?).
