Hi Virtualrain,
Thanks again for your helpful post in the Asus A8N-SLI premium motherboard setup thread, it saved me a bunch of work, and my awesome FX-55/7800 GTX setup is now complete.
I wanted to append my previous post, and answer your last question. I noticed many posters here are recent converts to the 2405, and probably haven't used that big of a display for more than a year yet.
In some cases, I believe that yes, the 2405 could be too big, depending on your ergonomic position, and the kind of dot pitch/resolution you are used to running. I agreed that the widescreen aspect ratio is more in line with our natural mode of sight, but at 24", your eyes will have to scan a lot more to take everything in. That's more work for your eyes, and this goes double with if you are sitting particularly close - perhaps witin 18 inches give or take.
I acquired my Cinema Display 23" about 2 1/2 (almost 3 more like it) years ago, and had a great time with it. I did notice right away however, that the 1920x1200 native resolution in Windows was much to tiny for me to read comfortably, and I had to increase the DPI and play around with larger fonts to compensate slightly.
Recently, due to work, I had to give it up and use a 17" Dell LcD for about a month and a half. I thought i would hate it, but got used to it suprsingly quick. Now, with my new comp, I went back to the Cinema Display in it's former position on my desk, and i'm experiecing dry eyes, slight eye strain and and almost a sense of naseau. Yes, I do plan to get my eyes checked, but in the meantime i've spent a lot of computer work on my 17", 15" and 19" LCD's in the house, and have experienced none of the these symptoms.
I'm experimenting with different viewing distances right now, but in this case i'm starting to suspect that yes, the display might just be TOO big, and might be causing some eyestrain. With my regular 4:3 aspect monitors, I can look at one singular focal point, which may have something to do with viewing comfort.
I wonder how the guys with those 30" monster Apple Cinema Displays do it? lol
edit: the one monitor i don't have any experience with yet is the 20" widescreen display, which might be more suitable, though this is just a guess, it seems to strike a nice balance between the smaller 17 to 19" dislplays and the almost too large 23 to 24" displays.
