i am always playing with 24'' and 1920x1080, because i am playing for fun only and not for leagues..
like players who want to get the best out of every scheme, with changing resolution everytime.
i also like the fact to see the whole map while playing, no mattter which scheme i am playing.. excluded big maps.
i have played a very long time with 1024x768 on my old pc, which was 9 years ago, when i started worms online, then switched to 1280x1024 on my mom's laptop.
in fact, i don't want to miss 1920x1080 anymore and i really recommend everyone to buy such a screen who doesn't yet, because it is really worth it.. not only for worms. (porns xd)
it is also not that expensive, i got 1x benq hdmi 2ms (140€) and 1x benq d-sub 5ms (100€) and the d-sub is also good.
