I've had my Inspiron 5423 for about two years now.
Recently, whenever I adjust my screen at certain angles, artifacts are seen on the screen. They mainly look like little green dots covering most of the screen. I JUST replaced the screen today with no luck, it does the same exact thing. What else could it be?
I should also note that whenever I have it hooked up to my TV via HDMI, no artifacts appear on the TV while they're on my laptop's screen.
