Such a problem for laptop Asus K52 observed noise in the image(mostly on white and other light colors), if you look at the screen, not directly but at an angle (looking straight at the screen, then all is well). What could it be? The nature of the noise — like TV interference.

Tested under Windows 7 native drivers (from the disk from the laptop) and have just loaded with Ubuntu LiveCD — the effect is the same.

By the way, "fonit" not everywhere — for example, against the background of the writing of this report not seen anything like it, and in place of "contiguity" of the label of the tab to the address bar (Chrome) — just...


PS: If you change the mode from True Color (32 bit) to High Color (16 bit) effect becomes weaker but does not disappear.

Speculated... Habr, tell me, please...

I have 2 thoughts come first:
1. Possible problems with the cooling of the graphics subsystem.
2. Maybe the graphics subsystem welling.
I think it's time to carry in SC.

've seen very similar symptoms on a cheap HDMI cable. Like the figure and the interference is completely analog. The snow they, or what are called.
Yes, one more question — it has always been, or appeared over time?

on the laptop MSI Wind U12 when connected to Full HD TV via HDMI and play 720p video at all "snow" appears. cable normal, from other sources not "SnagIt". the native monitor laptop "snow" doesn't appear. the effect is attributed to the lack of power and some overheating, because the laptop is clearly not designed to play hd videos on fullhd screens. (when reducing the resolution to 720p the snow disappears)
\r
a similar bug was observed on some samsung monitors connected via dsub at elevated contrast and shitty configured "contact pixel" (don't know what is it called when a picture can move a little until to a point is not eroded on multiple cells)

What kind of laptop, IN(intel/nvidia) or AB(AMD)?
Try to connect an external monitor to ignore the failure of the matrix or trail.
Disable composite, if there is one.
\r
//K52IN, no such problems.

A defect in the matrix.
Generally in cheap assah problem with the screen of a laptop, they have the loop break the loop, so the matrix is defective got.
