    Rough Gradients
    « on: July 26, 2010, 03:54:50 PM »
    Hello!

    I have one small problem and I hope you'd be able to solve it.First things first, I will tell you my computer specs:
    OS:Windows 7
    64 Bit
    2GB RAM
    512 MB Graphics Memory
    2.7 GHZ Processor.
    Now the problem I have is that the Gradients do not appear as smooth as they should.I mean there's not enough "finishing" between them.I can see lines repeating vertically in gradient-based images.I think there is any fault in color setting.But how can I get it back into smoother gradients.Wallpapers which have gradients do not appear smooth.I dont want those lines etc.In Photoshop when I create gradients, I see lines which just make up the gradient roughly.
    How can I bring that old smooth gradient back?
    Thanks

    Allan

    What happened between the last time it looked correct and the first time it didn't?

    Photoshop creates bitmap images. Are you zoomed in to 100%?

      There weren't lines between the changing colors of gradients and now there are :(.

      Even when I save them to png or jpeg, and open them using Windows Photo Viewer, those lines appear

      Colour ("color") depth set to some low level like 16 bit?

      Does it appear also using a different monitor of the same or higher resolution? If ever you can borrow or have an extra monitor.

        @patio.Its very new.And I am 99% Sure that wont be the problem.
        @Solmon No its 32 Bit
        @Jason No Not Only PS But everything

        Is there a way I can Show how I see it? Because If I show you any gradient-based image, you would see it normally.
        Like if there is a black/white gradient(vertical and black at the top)..Then Black wont smoothly go down to white.
        It seems like There are blocks of colors and you can easily see their borders as they are kept with different colors.(Hard to Tell :( :P)
        First, on the top, there will be a black block, then below it a lighter black, then dark gray block, then light grey, then white.And you can see the blocks' borders......

        Take a screenshot using Printscreen and upload it somewhere.

        If it looks normal to us, then it would be your monitor at fault.

          And hey..I searched around Net...and came to know..that what I am experiencing is Gradient Banding.....And after reading its definition..I came to know that it was exactly what I was experiencing..
          I even see some yucky green lines....and radial gradients seem really disgusting..
          Here's a screenshot of my gradient:

          fine here as well, either video card, or monitor issues. I'm leaning towards the latter, since usually a issue with the video card would appear on the screenshot as well.

          Unless you are doing something, like using a low quality DVI->VGA adapter.

            Can it be related to Color Profiles? On my laptop, it appears perfectly smooth as well.But my desktop is brand new so what can I do now?

            It would be kind of appropriate if we knew what display card, what method of connection to the monitor, and what monitor was being used.

            I don't see how you arrive at that conclusion; a screenshot takes the contents of video RAM and uses it to make an image file; if the video settings are 24 bpp or higher, there wouldn't be transitions that would result in visible steps; if an analog connection (VGA) was being used, the fault could lie in the digital to analog converters in the display card.

            Plug the monitor into the video output of your laptop, if it has one. If you see steps, it's the monitor. If you don't, it's the new destop's display card, and you'll know what to say to the vendor when you make your warranty call.
