I'm ordering my Thinkpad X41 w/ X4 Dock today. I'm psyched. I want to order a 19", 20" or 21" monitor for my office setup to plug into the dock-- my 53 year old eyesight can use the help, plus allows me to keep multiple windows open. But since the X4 only gives VGA output @ 1024 X 768 resolution, I don't want to pay more for features I'll never be able to use. So what kind of specs should I be looking for in a monitor??? Will I notice the difference in monitors with better-than-average smaller pixel size? refresh rate? ms speed? digital? Advice appreciated! (I've got all the reviews I need for rating monitors-- just don't know what I need.) THANKS!
