One of my systems (desktop) is running a new Acer S231HL bid 23-Inch Widescreen Ultra-Slim LED/LCD monitor via the DVI input. When I view JPG photos, either on my HD or online, I see several little dots the size of pixels. They are yellow color and some of them flash. It's as though they were stars in the night sky, you know how some twinkle and some don't? That's the way these flashing pixels behave. They aren't supposed to be that color. For instance, I have this photo on a hosting website and when I look at it I see 10-12 of these star-like pixel-sized yellow dots, most with black background, a few with blue background. What could be causing these. I ran Dead Pixel Buddy and don't see any dead pixels with any of the background colors.
