okay , so i did a search but couldnt find anything , am using my 17 inch iMac since aug 05 , and its set to 1440x900 , everything is fine but i cant find a lot of large images for my wallpaper , so i decided toady to set it to something lower , so its 1152x720 now , images for the wallpaper look much better since they dont need to be stretched or anything , but everything else i see (in safari,mail,iphoto..etc) looks smoother , images arent sharp anymore , do i have to change any settings ? or edit something ?? thanks guys!!
