There is a red dot on my LED monitor that can't be seen when there is a black, red, or blue background, but it's red when it's on a white background and it's seen when it's on a yellow or green one. I'm guessing it's stuck because it's not completely black, and I've already tried using JScreenFix overnight and UDPixel for several hours, I've tried tapping with a pen cap and massaging with my finger. I haven't tried the heat method, but I was wondering if there is anything else I can try. The monitor is only a little more than 2 weeks old so it's very new.
