read in a review the colors got exponentially worse the higher the frequency used, as far as i remember haha. i also use a 2nd monitor thats on 120hz max. got no issues with it running the way it does. if i want 144hz in a game i can still do that ofc :)
It would be nice to use a higher resolution 16:10/9 with good hz with other things/games though :/.
Im about to buy a VG248QE, but im having doubts it might dissapoint me with quakelive performance and have me throw it out and go back to ze crt.
248 is one of the fastest panels at the mo, i dont think you would be disappointed input lag wise. it has a pink ish glow on bright red colors though which really stood out for me at first. now that i got used to it i kinda dont notice it anymore. so ye, colors arent its strong point. BUT, i havent tried a custom icc profile yet which could improve that.
