The point of this page is to tell you whether your internet provider, your software, and hardware are conspiring to take away from perfect viewing.

The image below should appear as a rainbow starting and ending with red. There should be a smooth transition from color to color with no banding and no little dots, or noise. The background for this page is gray.



The following images are not a smooth transitions. If you have only limited colors the above rainbow would look something like these:


If that's the case, you probably need more video RAM, or a different video board.


That's color, now let's deal with gamma, and contrast.

Below are some boxes, one should be absolute black. Nothing on your monitor should be darker than the black box. Look at the black border around your monitor. It should be as black as that box. And nothing should be lighter than the white box.


<-you could adjust contrast and brightness to achieve this.

"Crossover" is when your monitor's R, G and B guns don't have linear curves. The chart below has boxes that go from black, to gray, to white. No colors should be visible: no pink, yellow or green cast at all!

If the boxes pick up a color, one of your monitor's guns is out of adjustment.

Gamma (or contrast) is next.


Step back from your monitor.
One of these numbered boxes is about the same shade as the surrounding.

That's your "screen gamma." Many photographer's web pages are designed for 1.8 Gamma. "Wintel" computers and TV monitors are calibrated for 2.2 Gamma. Photoshop, and Apple's Quicktime offer ways to change your gamma, if you so desire.
