    Question Differences between levels of DPI on monitors overrated?

    I want to try and keep this short and to the point, but i think a lot of people seem to think differences of say 80-90 or even 100 DPI are huge.

    Back in 2007 i had a 22" Samsung 226BW, which was a very popular monitor at the time for it's very low input lag compared to others like Dell which had input lag 3-4x higher.

    Now that monitor was 1680 x 1050, so it had a DPI of 90. Earlier this year i got a Samsung S27A750D (27" 120hz) that runs at 1920 x 1080 resolution. So moving from a 22" to a 27" you'd think the quality would be worse right? well, i put both monitors next to eachother and took turns playing Left 4 Dead 2 which has a lot of Aliasing on some objects like cars, thin pipes in the sewers etc.. it turns out i could not notice a difference between both. The DPI on the 27" is 81.59, so the actual difference in pixel density is less than 10% over the 22".

    I will say i noticed Aliasing in Left 4 Dead 2 when i went to the bigger monitor, but comparing both monitors side by side afterward they were indistinguishable in quality. So, maybe going for a bigger monitor just makes you see the flaws in games more rather than an issue with the lower PPI it's self?.

    At the time i had a choice of a 24" 120hz or 27" 120hz, the 24" has 91.79 DPI, i seriously doubt you can notice a difference with the naked eye of 10 pixels per inch, just as i couldn't over my 22" to 27"?.

    No it really doesn't make difference when you're looking at that small jumps, but you will see it very clearly with bigger jumps. Apple's Retina display in MBP has DPI of 220 for example and iPad 260.
    Never going to log into this garbage forum again as long as calling obvious troll obvious troll is the easiest way to get banned.
    Trolling should be.

    No it does make a larger difference, the problem is he went from a 22" 1680x1050 to a 27" 1920x1080. At computer viewing distances that 1920x1080 is roughly identical to a 1680x1050 22" monitor. If you put the 1920x1080 on a 22" monitor and a 27" monitor in a side by side comparison sitting at a computer desk the 27" would look like trash. 1680x1050 next to 1920x1080 is quite easy to spot if the monitors are of equal sizes, however if he steps back from that 27" a bit he will notice if becomes cleaner looking.
