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

[DanInPhilly]

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

[fixed]Monitor Pixel pitch Pixels/inch
20.1 " 0.258 98.4
22" 0.282 90.0
24" 0.270 94.0[/fixed]

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.

I'm not gonna check the math, but 24" LCDs also offer higher resolution than nearly all 22" monitors. The only exception would be the Lenovo 22" ThinkVision L220x which has a resolution of 1920 x 1200 or nearly 31% more pixels than a standard 22" LCD which only offers 1680 x 1050.

Through simply math and based on the numbers you provided, ThinkVision L220x's pixel pitch will be approximately 0.194 and the pixels per inch is approximately 130.4.

If you wanna know the exact specs then do a google search.

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.

The Lenovo ThinkVision L220x uses a S-PVA panel.

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)

Well, the difference is only 10%. You can sit X inches away from a 20" or 1.1X inches away from a 22".
Put another way, Y inches from a 22" would look the same as Y/1.1 inches from a 20".

I'm strictly old school regarding my bed activities ... i.e. dvd player, hd tv, no pc.
