Hey Guys,

I had a question about an issue I have been having for about 1 month on my monitor/computer. I bought an Asus PB278Q monitor off of B&H Photo and received the item and it looked like it was in great condition. I plugged it in booted up my PC and everything looked great. However, I then started seeing green specks/dots (extremely small) flickering on dark areas of a webpage or game. Anyone have an idea of what this could be? Monitor, Graphics Card, etc? I also noticed that these green specks/dots seem to disappear when i lower the resolution from 1440p to 1080p (haven't checked this in 2 weeks though).

Graphics Card - XFX Radeon 280x Graphics Card
Monitor - PB278Q
RAM - 16GB Corsair Vengeance
Motherboard - ASUS ROG
Processor - Intel 4770k
Power Supply - 750W Corsair
HDD - SSD EVO 500GB.

Thanks!
Will

gpu is not necessary to run a pc u have on board display driver for that.....and your processor already have a built in gpu i think intel hd 4000 ....so remove the gpu and put the dvi /vga/hdmi cable to the motherboard socket...

An ancient thread, but I thought I would post my solution in case anyone else gets led here.

I had green speckles on my Samsung LCD screen that I use for my Mac mini. These moved depending on the desktop image and window locations and were also on the window banners etc. Connecting by VGA or HDMI did not get rid of them. However, a large dark rectangle drawn in powerpoint, showed no speckles at all, so I concluded (wrongly) that it could not be the TV at fault. Others have blamed connections, monitors or video cards. My problem was solved completely by turning the Samsung off and on again using the power button on the TV. Normally it is left in standby mode when I shut the Mac mini down.
It is surprising that apparently so many different causes lead to the same symptom, but the old adage of "turn everything off and on again" worked for me. Whether the speckles return because something is on its way out remains to be seen, but for now all is well again.
