Smooth Radial Gradient

I need help creating a smooth radial gradient. It's okay when its really small (too small), but as the radial gradient ball thing gets bigger, I can see the lines. As shown here:

Or is it just that my screen is bad quality? I saw a few links on google but they didn't help me.

 

Can you tell me how you made that radial gradient? I don't mind getting those lines, seeing as it's going to be small.

 

Mine does the same..ive tried changing the resoultion on the document and it did not help. Im going to turn my screen resolution up and see what it does.

Edit:: You could try this, although i tried on a graident blur and it did not help as much as it showed.

 

Sure, anything to help a Photoshop-er. Click the Gradient tool (G). If it comes up as paint bucket, right click that and click gradient. Pick your 2 colors (put them in your foreground and background color thing on the left). Now click the gradient thing at the top left and it should come up with a bunch of gradient. Pick 1, or edit the colors to what you want. And then click Ok. Then click a spot on your sig (or whatever) and drag it to a spot. If you don't understand this, I'll make a quick gif showing you how to do this.

Ehh it makes it weird. I want something sleek and nice.

 

Cheers, thanks

 

The only solution I can come up with is just use a dark grey for your color, that way you dont have to turn the opacity down to make it stand out less and get those lines.

 

One thing I noticed is that if you make the gradient yourself, there are less lines then when you go to blending options and use the gradient overlay.
