I got a Asus R9 290 DirectCUII less than a month ago, and I've been experiencing these weird purplish dots on screen randomly. The chances are not high, it's my 3rd time seeing it.
Here's some pictures that I've taken w/ my phone.

I hope it's not related to the GPU because when I open different pictures, there will be different densities of the purple dots in certain areas of one picture vs the another picture. The purple dots goes away when I unplug the HDMI cable. It kind of goes away too if I wiggle the cable as well. I really hope it's a cable issue. Or maybe monitor?

True, but then it really doesn't happen that often. Just hoping it's a display issue or cable one since unplugging and replugging it in solves the issue. Guess I'll just wait to find out.
