Monitor generates a red pixel after some time

Hey! I have a strange issue, I couldn't find anything like this. So I bought a Samsung S24D300 a few weeks ago. It works well, didn't have any pixel problems etc. But yesterday I noticed that after some time (let's say around 1 hour after turning it on), it generates a single red stuck pixel, which is only visible on black background. But, after I turn it off for 10 minutes, it disappears. And as I see, it becomes brighter and brighter, still not that big deal (at least I will turn it off more often), but it annoys me, as my previous B300 also had a blue stuck pixel, and I cannot return it now. What can cause this? I will try running JScreenFix and other softwares after it appears, however it does not disappear if I massage it gently. Has anybody had any problems like this? Thank you.

EDIT: now I didn't have the problem for hours, then I started Skyrim, and the red pixel appeared immediately.

I couldn't fix it at all, so I forced the vendor to accept my return, you should try that too. I have bought a new one from an official store since then, it doesn't have any faulty pixels. Good luck!

Sounds like a hardware fault. I had an older Dell flat screen that, after it was in use for some hours and heated up, generated vertical bands of red pixels on the screen. After I shut it off and let it cool down, the bands disappeared. But once it got hot, the bands reappeared. As time went on, it took less and less time for the bands to appear. Since it was out of warranty, I had no choice other than to trash it and replace it.
