HD widescreen 24" LCD Monitors have no noticeable flicker at all. They are like a large white piece of paper. It is the High Definition attribute which does this. Its the same with HD TV's.
The reason for this is the presence of a thin plastic membrane covering the electronics which filters flicker and protects the electronics.
However, that membrane is easily scratched. If one shines a flashlight on a screen turned off, one can spot occasional scratches which are not visible at all when the screen is turned on or off without a flashlight. In addition, if one photographs the screen, one can see the membrane covering the electronics. On the old CRT's and non-HD LCD monitors, one can photograph the screen and will see the flicker but will not see the membrane.
That latter attribute is the down side of HD screens. They cannot be effectively photographed when turned on.
The other problem is that they may have a few missing or frozen pixels. They can be spotted if one examines the screens very carefully. Usually, not more than 1 to 5 are ever present. They usually have no effect on the picture.
All in all HD TV's and / or Monitors have thousand of color variants versus 4 shades of grey on the Kindle and 8 shades of grey on the Sony PRS 505. There is simply no comparison with the HD beating all competition, IMHO. Legibility is better than any printed book, hand held PDA or Ereader. There is NO eye strain if one has the top of the Monitor positioned at eye level.
