Screen Resolution

I just got myself a secondhand emac. I got an original Leopard disk and installed it. So far it works beautifully.
I noticed that when I put it to the highest screen resolution 1280 x 960, the windows seem to be (for a lack of a better word) shivering. It doesn't in the lower resolutions.
The current one as in the attached pic is... 1152 x 864. Even this has it in the tiniest sense.
The only time I don't see it happening is in the 1024 x 768. But I find that makes the fonts and menus too big for my taste.
Any ideas???

Here is my emacs configuration:
eMac 1 Ghz G4, 1 GB ram, 40GB HDD, SuperDrive, 32MB Graphics

Seriously,
any ideas on what could be happening??

What is the Refresh Rate when you are at 1280?

Sorry about my earlier post (I meant to reply with the same info I wrote below)...something "screwy" must have happened!

Anyway...I'm afraid to say that it sounds like some of the electronics relating to the display are probably going bad. I think that higher resolutions on CRT display's are "harder" to display or take more "juice"/electricity to do it.

This is just something that naturally happens with CRT displays that have seen a lot of use.

I have also noticed with CRT's displays (in my previous experience) that were having problems displaying at higher resolutions...that they may give off a "whining" or a high pitched sound as well.

Good luck,

That's just an unfortunate property of CRTs. The lower the refresh rate, the more likely you are to see problems. At 1280x960, the refresh rate is only 72 Hz. It's 75 Hz at 1152x864, and 85 Hz at 1024x768.

I used to have an eMac and I actually ran it at 1024x768 most of the time. Makes text big, yes, but the screen properties just look better. If you set the screen resolution higher, you can compensate by reducing your icon size and (in some cases) font size.

The Mac gives me only one option for each. It is 72 Hz.

I found out that the reason for the display problems is that my electric socket was giving some fluctuations.
I switched to another socket and now it is very good at the 1280 x 960.

Looks like I'll need to look into my house electrics.

Thanks for the advice guys. Its good to know that there is a place I can come online with my mac queries and have them solved.
