Photoshop question

[shmokes]

I've got Photoshop CS (1 not 2) and it kind of looks like crap on my monitor, but prints fine.  Weird.  I can only describe it as looking like there are moire patterns everywhere.  It's pretty subtle, but noticable and irritating nonetheless.  Any idea what could be causing this, or what setting I might change to fix it?  It's the only program that doesn't look right.

Check your screen color depth.  The higher the better.  But you surely know this already.

In Photoshop, check your image.  Image > Mode.  Work in RGB, 8 bits/channel

These are the only things I can think of.  Did previous versions of PS display correctly?

How does the image look in other programs?

The image might be to large for the screen so it's displaying with it zoomed out.  double click on the magnifying glass so it will zoom in to 100 percent.

It could also be your Edit>Color Settings...  Is set to some goofy Mac setting.

Our Graphic guy would use a custom Mac color setting and everything he created would look like cr@p in my Photoshop, but would look fine in other programs.

Make sure your desktop color depth is set to 24 or 32 bit. If you have it set to 16bit, you're going to get either color banding, or "dithering" (which is a pattern like you described).

Next in Preferences, under "display and cursors" check to see if you have "diffusion dither" checked on. If so, uncheck it.

Thanks.  I'll try those.  Without looking at it I know it's not a screen size issue or a color bit depth issue.  The screen is enormous and I'm sure that the color is set to 32-bit.

I figured out the problem.  The image mode was already set to RGB, but if I click on the View menu and click Proof Setup,  and click RGB in there it clears everything up.  The weird thing is that it was set to CMYK when I went in there and I switched it to RGB.  But when I opened it with another file my wife made it already had RGB checked, yet the problem was still there.  In spite of it already being checked, though, clicking on RGB still fixed the problem.

Anyway, just thought I should throw the solution out there in case anybody else ever runs into it.

Other thing could be pixel aspect correction, I know it makes things look a little crazy sometimes.

BUT, did you check that dithering option I mentioned?
