To test your system:

Open your "System Preferences" panel

Choose "Appearance"

On the bottom of this panel where it says, "Font smoothing style" choose "Light"​

Now close out "System Preferences" and also close TextEdit, if you had it open.

Note: You have to close the application and relaunch it for the changes to be seen.

Now launch TextEdit and bring down the Edit or Format menu and take a look... Do some of the letters on the drop down menu have rainbow colored edges? Slightly colorful edges and not black or dithered grey?

This seems to be a problem when in Vista with bootcamp as well.

The driver version does not matter, since I am running the new catalyst drivers in bootcamp and the older drivers used by Apple in OSX.

I have also tried both ports on the 4870, the mini and DVI, no difference.

I think this could be a problem with certain cards, or maybe even with all cards. Not sure really. It'll show up when doing word processing. Pretty annoying.

Thanks for checking this out.
 
I don't see it on my. Is it suppose to very noticeable? I'm usually not sensitive to these things.
 
Nope.

No problem here on my 2009 Mac Pro 8-Core 2.93GHz (NVIDIA GeForce GT 120 512M) + Apple 24" LED Cinema Display.

What are you trying to prove?
 
LOL Not trying to prove a thing. I came to find out it has to be the AA. I have seen it on nine 2009 MacPro's, and a ton of windows boxes. It is a red/blue tint around fonts. If you don't see it I would assume you either have a really good monitor, or you're blind. I mean how can so many computers with so many different GPU's have it. If something is wrong, though, I would want to know while still under warranty. But like I said, it appears to be typical of font aliasing.
 
can't see it on mine (usually sensitive about these things)... i have the 4870 and an hp lp3065 (30" lcd)
 
I do not see the problem you are describing under normal circumstances.

However, if you enable the ZOOM feature in Universal Access, then zoom right in to a menu, you do see colours around characters, but this is normal for this method of anti-aliasing.
 
I've seen this with all sorts of computers and GPUs. Hardly unique to the '09 machines. :)
