is the sony e400 a perfect flat monitor? nt

According to the Sony web site the FD trinitron is and I quote
"The virtually flat, high-resolution FD Trinitron® CRT"
Keyword virtually. But hey I'm splitting hairs here.
Also remember that with the exception of the LG CRT's all so called flat CRT's are still curved on the inside. In simple terms they put a piece of flat glass in front of the tube and charge more for it.

Not necessarily, the ability to display fine detail on a computer monitor involves many factors including resolution, dot pitch, spot size/shape and convergence. In my opinion convergence is one of the most important aspects of a monitor's performance. It determines how sharp the characters in your text document or spreadsheet look. Convergence has a direct effect on the monitor's apparent focus. Unfortunately, convergence is a spec that few manufacturers publish.
There is a reason that the original televisions had almost round picture tubes and that today the IMAX theaters use a domed screen. In general it is easier keep focus consistent if you project a beam onto the inside of a curved surface. Almost every monitor has better focus in the center of the screen than at the edges. This is because the beam is at right angles to the screen. The trick is to keep focus uniformly good over the entire screen. Manufacturers have developed technologies (dynamic focus circuits, etc.) that do a good job at improving beam shape and size in the corners of the screen. However no circuit or technique can make the beam 100% accurate. On average and because of these facts, I believe that monitors with slightly curved screens will produce better text. This is why many people believe that shadow mask monitors provide better text images that aperture grill technology. Shadow mask monitors are curved in two directions like a ball and aperture grill is curved in one direction like a cylinder.
Try this experiment. Take a flashlight and aim it straight at a wall you will see the spot the beam creates is sharp and round. Now aim the flashlight up into the corner of the wall. You will see the beam shape change to a more oval shape and spread out. In general terms this is what's happening in your CRT monitor. The flatter the surface the more the beam spreads out or defocuses. Now imagine that you are in an IMAX domed theater. If you shine the flashlight at any portion of the inside of the dome, the beam shape and size stays much more consistently focused.
In my opinion the only real benefit of flat CRT technology is slightly better glare reduction. There are many ways to reduce glare and reflection and save $$ at the same time. For example: Remove some light bulbs, change the position on the monitor or glare source, use reflective lights instead of direct lighting, use after market anti glare panels and shades, close a window shade, etc.
I'm not saying that the LG CRT's will look bad. On the contrary, My point is that monitors, like all electronic equipment will vary in quality and performance, even when comparing two of the same model. This is why I have such a hard time with the posts I see on this board saying "my brand X better than brand Y". A single unit from a statistical point of view means very little.
When you purchase an electronic device what you are really purchasing in my opinion is the company that sold you the product. What I mean by that is, will the company stand by its products should you have a problem. How easy will it be to get in touch with their tech support should you need them. Do they offer special services like enhanced warranties that you may require etc. Do your homework before you make a purchase.
From what I can tell, the differences between the e400 and g400 are as follows. Both are capable of 1600 x 1200 at 85Hz. Although Sony recommends the e400 be run at 1280 x 1024 at 85Hz. The G400 is TCO-99 compliant, a more current standard the e400 is MPR-II compliant this explains some of the cost differential. The most likely difference is where the monitors are manufactured, call Sony and ask. Yes contrary to popular belief Sony uses third party manufacturers like just about everyone else in the electronics industry. In fact I have inspected the factory where the "E" series is manufactured.
Good Luck
