    I usually refer to artifacts when I am talking about a 3D rendering glitch (usually a driver glitch) or caused by over heating due to an OC.

    But I guess that user might have been refering to glitches that appear due to the higher resolution of a computer/laptop screen and the fact that it can display more colors, at which point compression glitches become more apparent. While TVs are just too inferior to show these glitches.

    Can you give a link to the post, please?

    usually if your getting artifacts (look like little white or pixelated boxes) while playing games, it is usually related to overclocking. A stable overclock will show very low amount of artifacts.

    LuckMC11,

    When watching movies, the artifacts I was talking about happens when video is compressed. A normal movie must be compressed from it's original format to fit onto a DVD. The compression will extrapolate (guess) from one pixel to the next. This guessing doesn't give a 100% acurate copy of the source.

    This pixelation/artifacts can really be noticed when looking at a stationary black background. You'll notice small, almost bluish boxes throughout the black area. This is where the compression will drop some data (since it's black and stationary) to save on space. You may also notice between the edges of black and white (where they meet). This is usually where it gets fuzzy/grainy, again because of the compression.

    If compressed really well, you may not really notice it, but look carefully and you will see the artifacts (best on black) when watching on your notebook. Output it to your TV (using your notebook) and see if you can see the same artifacts. In most cases, you wouldn't unless it's really bad.

    Hope this helped.
