>I'm fairly uninformed when it comes to display adapters, monitors, etc. I currently have an ATI Radeon X800XL with 256MB of memory. I started having some problems with my CRT monitor (or maybe it's my eyes), so I ordered a Dell UltraSharp 2007WFP 20-inch Widescreen Flat Panel LCD Monitor the other day.

>Now, what do I do when it gets here :)? I've been working in 1024 x 768 for awhile now, but would it be better to move to a higher resolution? Also, what about refresh rate? My current CRT monitor supports refresh rates of 60MHz, 70Mhz, and higher. Is a higher refresh rate easier on the eyes?
