Monitor resolution: 20" just as good as 22", apparently

Hi,
I did a little research on monitor resolution, here's what I found ( http://en.wikipedia.org/wiki/Dot_pitch )

Both the 20" and 22" monitors are 1680x1050, so the smaller one crams the pixels into a smaller area so it has better resolution. You can of course sit further away from the 22" (9% further to be exact) and it will give the same appararent res. as the 20", but then the field of view will be the same! Conclusion: if you're considering a 22" monitor, save your money and buy a 20" and just sit a little closer.

Note that the 24" is a different matter. Its pixel pitch is still a little worse than the 20", but you can sit further away (4.6%) to get the same res and the field of view will still be larger by 15%. Whether it's worth the money is a different matter.

Hope my math is right - corrections welcome.

Well, that's the first 22" I've heard about that wasn't 1680x1050. Some web posters think it might also be S-IPS or P/M-VA (true 8-bit color) rather than TN. So: better resolution, better color, that explains why it costs twice as much.

hhmmm obviously sitting farther away would be better right?.. you wouldnt want to watch a DVD on a 20" sitting close to it..

you would rather have a 22" and lay in bed relaxing right?.. (my pc is in my room)

true.. i dont have a HD TV though... thats why i use my pc, hey im happy =)
