I have two major questions (somewhat related):

1) The first is about the resolution setting in the maximizer screen that is just to the right of the "enable maximizer" checkbox. This seems to default to 800x600, has a number of selectable resolutions in the dropdown (including a "1 to 1" entry), and I believe it also can be typed over to specify any XxY resolution. The question is... what does it do? My assumption has been nothing because it seems to me that I'm setting resolutions for the regions to whatever I want them to be when I define my regions in the top portion of the maximizer settings screen.

2) My bigger question is what I should be setting my resolutions to on my 30" monitor while playing 5 clients. Having tried out basic schemes of where the main and slave regions are located on the screen, I've decided I like to have the four slaves in a column on the left side of the screen and the rest of the monitor used for the main window. My monitor runs at a default resolution 2560x1600. So I've been using the following settings:
Region x, y w, h
slave1 0 , 0 512, 400
slave 2 0, 400 512, 400
slave 3 0, 800 512, 400
slave 4 0, 1200 512, 400
main 512, 0 2048, 1600

This allows me to use the entire 2560x1600 resolution of my monitor and things look quite nice. I've kept the resollution drop-down at it's default 800x600 and basically ignored it. I guess the ratios of the slave and main windows aren't exactly the same in this configuration, nor are they the same as the 800x600 setting in the drop down, but it does make the most of my monitor.

Running this way since WotLK I've noticed that swapping windows is pretty slow and I can only swap about 5 times before the video card (a 8800 GTX) starts producing artifacts on the screen and my FPS goes to 3, which requries a reboot to fix. So I don't use the swapping feature much. But even if I don't window swap there will come a time 3-4 hours after playing that I'll get the artifacts and 3 FPS thing anyway and have to reboot. Not sure if this is related to how I set up maximizer.

However, messing around today I thought the drop down might actually do something, so I figured since it has a ratio of 4:3, maybe all my windows ought to have that same ratio. So I came up with a new scheme that makes the slave regions, main region, and drop down setting all have the same ratio of 4:3. Here it is:

Region x, y w, h
slave1 0 , 0 512, 384
slave 2 0, 384 512, 384
slave 3 0, 768 512, 384
slave 4 0, 1152 512, 384
main 512, 0 2048, 1536

This fills the width of my monitor, but only takes up 1536 of the 1600 pixels on the vertical portion of my monitor. It looks a bit odd, but isn't that big a deal.

The question is.... is there something "better" about the 2nd setting where all the scales match? Does this matter or should I just go back to the first settings I've been running for 8 months or so pretty happily? What advantage does matching the scales of the slaves and main give me? What advantage does matching the region scales to the drop down setting scales give me?

OK, enough of this - just wanted to make it perfectly clear what I was asking. Thanks in advance for sharing your wisdom on the matter.
