Well, once again I agree w/ @Stevech's recommendation, I've had great experiences with Samsung LCD (conventional) & LED backlit monitors. I've worked in jobs where it was critical to have two widescreen monitors of display in front of you at all times. I actually outfitted my home office w/ the exact same setup I had at the "real" office (and several other guys in the office ended up duplicating my setup, just because it was very user friendly).
This was a few years ago, but most of the basics still apply. I used 2 x 24" Samsung LCD monitors with VESA standard mounts on back (ie I ditched the stands that they came with) and used
Ergotron desk mounts. I drilled one small hole in each desk (home office and real office) and it cinches up very tight and even holding 2 x monitors w/ articulating two-arm extensions each, it was extremely solid. You can rotate the monitors (even have one in landscape, and one in portrait, or both in either mode), each suspended by an arm that will only move if you physically push/readjust it yourself. I can't say enough good things about the Ergotron mounts. Getting that much monitor real estate up and off your work surface is also a very handy thing. You can have the base towards the back of your desk, and the monitors hover 15+" towards you, with no stand or cables under them, it's great.
Ergotron mounts aren't super cheap, but they are a great value - you will use them a long time without complaint and they will probably outlast your monitors. I still have at least one, maybe more, in a box.
The articulation points can be tightened or loosened with an allen wrench depending on how much tension you want there to be in the arm.
At that time I specifically chose 24" through a process of trial an error, eventually figuring out that a 1920x1080 monitor could display two full size 8.5x11" PDFs side by side in more or less "actual" size, without scaling much (or at all?). Different professions and use case scenarios might dictate certain modes of positioning or certain resolutions as being better or worse, but as a bare minimum, I found 1920x1080 x 2 monitors to really do the trick that I was looking for.
PS - sometimes a "value line" of monitor by a brand won't have a detachable base and no VESA mounting holes on the back. Just check your monitor specs carefully before you buy if you go the stand route. Also look at the weight and look at your stand's max capacity.
HTH!
