I see that some of the higher end monitors have "self-calibration" tools, or are "factory calibrated". I guess that the hardware calibrator takes into account ambient light as well, am i correct? What do you mean by "proper lighting"?
I would need to get another another monitor anyway, because the one i have now lacks tilt/height settings, and i either have to sit straight and get weird colors, or hunch the back to get a correct angle of view.
3rd party monitor stands cost as much as monitors, so i guess i'm better off getting a new monitor. The hdmi on my motherboard supports a maximum resolution of 1920x1200, so going higher than that would require a dedicated video card.
The bucks-up self-calibrating ones will monitor (sorry) themselves, but the calibrator device only sees one part of the screen where with an external calibrator you can spot-check the entire display for uniformity. Factory-calibrated is great for when the display leaves the factory with a few minutes' run time, but I wouldn't take much from it.
The lighting in your room (which will mix with the light coming from your display) will affect your calibration, I can't tell you what is ideal but I have white walls in my office and it is lit with GE Reveal incandescent lamps which seem to work well.
The i1 display pro I have can measure screen flare as part of the calibration process, and it can monitor ambient light level (if perhaps not colour) and adjust the brightness to match.
Finally I've found HDMI troublesome for getting calibration routines to deliver good results where DVI has worked; that is only my experience though, your results may vary.
