@bigc -- Very helpful info re maintenance of LCD screens. Many thanks! @everyone - From what you folks have told me (& from the links you provided) I have learned that the best thing is to set my computer's resolution at ~ the same setting as my monitor's native resolution. This puzzles me a lot because... BACKGROUND- Pending replacement of my dead 19" LCD monitor, I am temporarily using an old 17" CRT monitor that I had lying around. PUZZLEMENT (example)- 1- A particular monitor that I have on my "short list" of candidates-for-purchase has a native resolution of 1680x1050. 2- To get an idea of what that might look like, I set my CRT monitor to 1280X1024 -- the closest I could come to 1680x1050. At that setting everything was so tiny that I couldn't effectively see what I was doing. 3- Obviously I'm doing something wrong (unless everybody except me has microscope-vision). QUESTION #1- If I buy the 22" 1680X1050 monitor, & set my computer's resolution to that same setting, are the icons and text going to be microscopically tiny? Or what? QUESTION #2- What resolution do you people have your computers set at? Why? P.S. --- In case you haven't already noticed, I don't even know enough about this to ask intelligent questions. Even so I am having a delightfully good time learning from this thread.
