Why does my laptop have grainy static on the screen like a bad tv reception?

post #1 of 14
Thread Starter 
my pc is a samsung laptop with a amd a6 3420m. I noticed that there is a problem with the screen that doesn't happen on other monitors or laptops in the house. It's a beautiful display, but I notice in darker areas, like shadows in games, desktop etc.. There is this grainy fuzzy static like a tv with bad reception when the color is set to 32 bit (which is the stock color) on 16 bit, it is not present. Also, I notice around logos and text, there is flickering green dots in 32 bit mode, like when an image becomes blotchy around it and you see like clustered pixels, some are flickering some just stay on. It's like an extra transparent layer of words around a white logo on a black background that are made of of green flickering pixels/dots. The whole problem is like this on certain colors: http://www.plasticbag.org/images/extra/grainy_three.jpg. It flickers too just like a tv.

A dark blue or grey will appear staticy/flickery, while bright colors aren't noticable. I connected it to an external monitor and it works fine with 32 bit on there.

It's the same with my screen with dark grays. Perhaps it's normal.

Do you have static when viewing dark blue areas too compared to light blue? It's almost as if the screen cannot handle those colors and the static/noise is making it break up. It's really strong on my pc.

Are you using the native screen resolution?

Probably just signal-related. Those things are affected by electro-magnetism and radiation, some connections and devices are more sensitive than others. You shouldn't worry. As the person before me says, double-check the resolution smile.gif

Then don't worry about it. Maybe poorly grounded, who knows. Maybe you just live in a static/magneric/radioactive (safely radioactive tongue.gif) area and this particular laptop is more sensitive than usual. No, I don't have static on dark blue, only on dark gray, and a certain tone.
That's why it's gone with 16-bit color - because the screen is not showing the exact color, but the nearest available, and the nearest available signal doesn't resonate with it smile.gif

Maybe it's the screen not handling the colors? 32 bit is window's standard, but the screen is cheaper. The laptop was $380
