I have an Alienware 15 R2 with a 4k UHD display. Within the past 6 months or so, there has been an issue with my screen that pops up every now and then when I open my laptop. "Stuck pixels" is the best that I can describe it as, even though I know this is not the correct technical description. As shown in the pictures, there are thick lines of pixels that flicker between showing the current picture and what the pixels are "stuck" on (in one case for instance is showed what was on the desktop). The problem slowly fades away after a couple hours on. Also, the problem does not show up on an external display. I haven't found anything online like this, and was wondering if this is a serious problem I need to fix or if there's an easy solution to this. Thanks.
This could go from a loose wire or dirty connector, to an LCD replacement.
