All your screenshots look right to me

I wonder... what is your color configuration in windows, do you use extreme values for contrast or brightness or hue? I could imagine you'll see artifacts if the usually dark areas of the pictures are too bright or are too much stretched in the mid-ranged brightnes levels...

edit: I've an idea to test this...

in the spoiler is an artefact free gray ramp, so if you see artifacts in it, something is wrong other than color settings

I don't think it's a hardware fault but the standard artifacts you see that are inherent to the decoding/encoding of videofiles, especiallly in darker scenes.. or lower bitrates/resolutions.

If you watch a youtube video wich are low bitrate low resolution files, you see them everywhere.

Like Ledgem said, an LCD in contrary to a CRT has a high contrast, and images are therefore more clear and brighter. things you have a hard time seeing on a CRT you see much better on a LCD..

If I watch a fansub on TV or I watch it on my LCD.. it makes a world of difference.
I'd say it's that and nothing more.

Can't see any artifacts of any kind on what you posted. I only see the problem in video playback and in my VLC snapshots.

The first four images all looked a mess due to the problem being froze, so I'm not sure how you can't see what I'm talking about. Then again, my problem is more with how messy it looks when in motion rather than how it looks in a snapshot...I suppose it would come across as me being super picky with the evidence on offer.

I think I'll just give up, got enough monitor problems right now without this. I just find it very hard to believe this is normal... I almost wish I could show you guys what I'm on about on my PC.

Thanks to everyone who tried to help me.

Well, one other way is to video tape what you're seeing with a digital video recorder.

It's starting to sound like a codec issue now. Though, it's strange that we can't see what you're seeing. That leads me to believe it's either the monitor or the graphics card. As some have pointed out, it's possible that there's some kind of interference as well. The next best thing is to move the computer and monitors elsewhere and test them out there. I also highly advise to test out the monitors on another computer to see if the problem follows the monitors to the other computer. This is one of those cases where you have to test every hardware and software that may be the culprit one by one, not all at the same time.

Well, in that case... if your graphics card supports color correction you might want to try another color setting. Let me explain by using this nVidia color correction thing as example:



regarding lossy compressed videos:

The digital vibrance slider intesifies colors (on 100% it looks like one has an lsd trip)... uhm, not advisable, since it will amplify colored artifacts.

The next thing is brightness, if this is set to a too bright level, one will see artifacts in dark areas.

Next thing being contrast, if this is set too high, it will amplify artifacts of any shade and color.

Gamma is similar to brightness, but instead of cutting the color space and stretching the cut part to the former size of the color space, this thing will squeeze the color space in a way, that medium values become extreme... so there is significent change in middle bright colors/shades and not so much in the extremes shades/colors.

Thatswhy, in your case I'ld suggest to decrease gamma and maybe contrast values. This will significantly reduce the visibility of artifacts.

It could be a codec issue, but codec issues are usually pretty severe. As in, if it'll even play fully and you can even see video, the blocks appear as bright pink and green (that was my particular experience - DivX forcing itself to play XviD-coded files against my will). What counters this is the fact that it's visible on DVDs, too - DVDs use proprietary codecs, don't they? So it shouldn't make a difference.

The only possible explanation I have for the DVDs is that they might be bootlegs, in which case you'd see the encoding issues there, too.

@Jinto Lin

Thanks for posting the detailed information on what the features do and don't do. I know ATI CCC gives you the same or very similar options, so I'll download it again and mess around with the settings tomorrow.

@Ledgem:

Nope, the DVD I tested isn't a bootleg - It's the official one. *shrug*

@Phantom-Takaya

Going on my quick DVR price search, I'd be better off putting the money towards a better PC. Why does everything have to be expensive...stores should give discounts to cheap people.

Moving my PC and monitor downstairs/to another house wouldn't be a problem. I'll probably try doing so sometime tomorrow, depends on my mood after my 5th replacement monitor arrives (backlight and pixel faults, not related to this issue).

Anyway, time to watch the last hour of the third Naruto movie and then get some sleep.

I think this supports the theory of a monitor malfunction. I certainly fail to see where the graphics card could be involved in this. You'd get other sort of weird things, I reckon. At least *I* got all sort of weird things when my Ati Radeon 9800 Pro was acting up on me.

But if it's a monitor issue, wouldn't he be noticing distortion on other applications as well? (Even in day-to-day usage, why limit it to specific applications)

It's possible that the less graphic-intensive it is, the less obvious it is, and vice-versa. But, that's a ballpark guess.
