hi im new to these forums, seems like a nice helpful place

my problem is for the past few days (today is the 3rd day to be exact) i have been having severe banding issue with not only photoshop, but paint tool sai as well (and i assume any other graphics software)

i have tried everything from calibrating my monitor, messing around with photoshop settings including diabling opengl to completely reinstalling my OS to no avail. im pretty sure the issue does not lie with my monitor or graphics card (as it was working perfectly fine before)

here is a screenshot:

zoomed in:

this makes it impossible for me to paint as the more i try to blend colours the harder it becomes, the shades become less and less until i cannot blend anymore. if i try to blur it, more lines/banding appear, there is just no fix. it seems odd because i can view gradients very smoothly around the web or on images i download.

i am using photoshop cs5 on windows 7 home premium x64

ive tried everything to fix this, any help would be appreciated

What exactly do you mean by lines ? I see just blur, could you, please, specify or even better show with some arrows ?
Thank you,
Peter

in this picture i can only see about 5-6 shades of grey, despite using the fuzzy brush to try and blend the shades together, they wont blend :(

are the brushes at full opacity or have you changed the opacity. when the brush is selected check the bar at the top (below the menu bar) to check the settings for your brush tool.

everything in this one was done with the soft brush, yet there are hard edges when i attempt to blend

Beats me, I hope somebody with more knowledge ( or imagination ) can help better, I have just few thoughts :
1. If it is not only Photoshop, but also some other pain tool outside Photoshop I would search in components common to these two software.
2. If it is fine before blending, I would check ( and even post here in the same manner as for brush ) blending setups.

As you have re-installed the OS and PS, have you updated the your software and drivers to the latest patch/driver etc.

looks like a problem with your PS program, bro. Might have to reinstall it, something similar happened to me with GIMP.

yup, everything is up to date

I thought it would be beneficial to post blending the same way as you did with brush.
okay sure, here you go:

i have re-installed photoshop already, made no difference

I may miss something, but this is again brush with everything on 100%, one layer, how do you blend ?

i use the eyedropper tool and just pick whatever colour is on the edge of the previous stroke, then stroke some more, and repeat. It just reaches a point where the colours are hard edges for some reason and it wont blend anymore

the sample size is "point sample" and i dont know exactly what you mean by colour setting, but my pictures are usually 8bit RGB colour, but i've tried using 16 bit and the same thing happens x_x
