I have a 21" intergraph (Hitachi); similar. Set up the room lighting the way you will want to work. Start X and have a light background. Just open an xterm so you have something that is supposed to have straight lines, enlarged to almost full-screen (leave a 1 cm of the desktop showing. White background. If you can find a test-image on the net, display that instead of the xterm. Personally, I use _The_Sound_of_Music_ 40th aniversary DVD in VLC with deinterlace blend (hardware conversion). Adjust the screen size, positioning, and shape (e.g. pincusion), moving the xterm around and comparing its borders with a real straight edge. You'll probably end up with a 5 mm black border around the edge depending on the CRT. Likely, you can adjust your color temperature, which should probably match your lighting source (e.g. standard incandesent is lowest in the menu, full north blue sky through a window would be highest). Contrast and brightnes are somewhat subjective, but basically a full-contrast image (best with a test-pattern, otherwise a very good DVD movie) should have the blackest parts just as black as the border at the edge. The very whitest and brightest parts (e.g. the sun reflected off something) should be full bright with a full range inbetween. If the contrast is too high, medium dark will be as dark as full black and medium light will be as bright as full bright. If the contrast is too low, there'll be a haze over the image. Depending on your xorg driver, you may be able to tweak it. Check the docs for that driver. For any controls that you have that I haven't mentioned, try a google search. Enjoy the monitors.
