I wish to replace a CRT Display Monitor with an LCD Monitor. Are they all compatible? Do I have to change the VGA board, driver, or connector plug.....or is "plug and play". Thank you.
You should need nothing more. Most monitors are all PC compatable unless they say otherwise specifically. Most all install Plug and Play, but you can also install their dedicated drivers if you wish. With the higher end LCD they may run a little better on DVI (digital connection), VGA or analog (same conector as on your CRT) though is almost as good. They come complete with both cables from Dell, and some other manufacturers, but check. Warning; once you go to LCD you will never go back to a CRT.
Be sure also you are comfortable with the higher resolution they must run in. Adjust your current CRT resolution to 1280x1024 to mimic a 17 or 19 inch LCD, 1600x1200 for a 20" plus LCD. Also keep in mind, with an LCD size is what you get, 19" is 19" viewable, not 17.85-18" viewable for a 19" CRT.
Check the back of your PC and see if you have a DVI connector already. Here is a view of a Radeon card connectors.

Using my 1800FP, text also was not quite as good as on my old 17" Trinitron, even using the DVI mode, which only worked for 2 weeks before going into the commonly experienced defective DVI power saving mode. After hours of adjusting font sizes and using bold type in many places, the 1800FP is now good enough. Use of Cleartype did not solve the problem. Dell tech informed me that they are working on the DVI problem. Hope the problem is solved before "Consumer Reports" sends me their next product survey.
I too have to use 1024 by 768 or else the typical Web page is too small.
As many other people have told you, the problem you are having is not due to the 1901FP monitor. I am 68 years old and I can read type on my 1901FP from six feet away. It is brilliantly sharp and clear - - far better than my 19 inch Trinitron CRT. LCD monitors are inherently sharper than CRT. All Web sites I visit are sharp, clear and easily readable at 1284 x 1024, the native resolution for this monitor. I have the Internet Explorer type size set to medium and can read it without difficulty, and my eyes are none too good, I might add. I can set it to smallest and still read it easily.
There is something wrong with your settings, not your monitor.
I agree with robnich's above reply. "There is something wrong with your settings, not your monitor."
I have a Dell 2000FP running at native resolution 1600x1200 and text and graphics are crystal clear and graphics are gorgeous. My eyes are pretty old, as well.
I will never go back to those clunky old CRTs. They also generate too much heat into the room.
