This article explains some of the differences between LCD and CRT.
The requirements to prevent flicker are different.

LCDs have visual artifacts, but they're different than a CRT. If
you want to understand this better, go to a local big box
store (Best Buy), and play with their display computers.
Usually, they play a movie on the screen, but what you
want to see is a text document (type some text in Notepad).
Then, scroll the text window rapidly, while watching what
happens to the text. That is the kind of artifact
I'm referring to. By seeing a demonstration, you'll get a
better feeling of whether an LCD is right for you. While
you're there, you'll also get a chance to see the two kinds
of surface finishes on the monitors - the antiglare ones
make text harder to read, while the ones with a glossy
finish are better (as long as there isn't strong lighting
that can bounce off the screen, where you work). Mine has
a glossy (glass-like) finish, and the glass is easy to clean
(no special cleaning products needed).
Initially, I found the light coming out of the LCD screen
was annoying, compared to my previous CRT. But after using
it for years, I'm used to it now. I was almost getting
headaches from it at first.
So if the LCDs at Best Buy look OK, that means you should be
able to buy just about anything, and have it work for you.
You can read the reviews at Newegg, as the reviewers sometimes
notice other effects (such as a few monitors with
exceptionally high "lag" or delay between sent images
and when they appear on the screen). The lag effect is
important in gaming and "first person shooters".
There are different panel technologies, and some panel types
have a wider viewing angle (so the colors don't shift as you
move your head from side to side). Some of the panel types
are also better for Photoshop. To see examples of really
expensive ones, there is a second article I like to use
as an example. One thing that can be different about
the expensive monitors, is they can use LEDs instead of CCFL
(cold cathode fluorescent lamp) as a backlight, which
affects the color range possible.
