Dude, these are JPEG compression artifacts, not banding :D

Here's an example of a Steam discussions forums background:

The JPEG artifacts are quite visible.

It's the DOTA 2 character select screen

EDIT:
I know some of it is jpeg artifacting, but if that was the only issue then we would all have that same picture

Uh, no. It's a background image from the Steam forums. I'm talking to the OP, btw.

1112e, it looks like you could use some monitor calibration. Notice how the bar doesn't blend fully to black in your picture?

Try: Gamma 4 or 5 and Contrast 45. Shut off Black eQualizer (Use the Standard Mode preset to do that).

That's a relief, thank you.

1112e:
Are you talking about those strange bars in your picture that almost look like a different color than the rest of the bars, looking like a very faint pinkish and greenish type tone?
?
I definitely do NOT get that on mine...and I even tried black equalizer at 20 with contrast 100.

Then I expanded the test image to 400% and I can see distinct very thin vertical rectangles that do NOT have strange or corrupted colors, but seem like individual gradient changes, which looks completely natural, basically, borders, which are not a strange color.

I then switched to 16 bit color (back to 100%) and I can clearly see not only individual thin rectangles (which were literally completely invisible in 32 bit) but also VERY distinct, repeating patterns of faint pink/green which remains mostly even in intensity and repeat throughout both gradient bars, which are 100% NOT visible in any shape or form in 32 bit.

Are you running 18 bit or 24 bit color or something? (although I read somewhere that 32 bit is basically the same as 24 bit anyway)...

I'm running 32 bit color.
I don't see other colors really, i just see banding/lack of smoothness in the gradient.

Ok after seeing that video driver control panel and checking back on page 1 again, and realizing that you don't have a Geforce or Radeon card, I blame the laptop.
In fact I fully blame the laptop and that intel HD 3000 graphics.

Wait for your desktop.
guarantee you it will be fixed.
