모니터는 iVIEW라는 모니터를 사용하고 있습니다...
xorg.conf 첨부하겠습니다..

# Specify which keyboard LEDs can be user-controlled (eg, with xset(1))
# Option "Xleds" "1 2 3"
# To disable the XKEYBOARD extension, uncomment XkbDisable.
# Option "XkbDisable"
# To customise the XKB settings to suit your keyboard, modify the
# lines below (which are the defaults). For example, for a non-U.S.
# keyboard, you will probably want to use:
# Option "XkbModel" "pc102"
# If you have a US Microsoft Natural keyboard, you can use:
# Option "XkbModel" "microsoft"
#
# Then to change the language, change the Layout setting.
# For example, a german layout can be obtained with:
# Option "XkbLayout" "de"
# or:
# Option "XkbLayout" "de"
# Option "XkbVariant" "nodeadkeys"
#
# If you'd like to switch the positions of your capslock and
# control keys, use:
# Option "XkbOptions" "ctrl:swapcaps"
# Or if you just want both to be control, use:
# Option "XkbOptions" "ctrl:nocaps"

이렇게 설정이 되어있는데..
왜 1280x1024 로 설정이 안되는건가요? 제가 설정을 잘못한건가요?
그리고 모니터는 삼성이나 여러가지로 바꾸어 봤는데 더이상 높은 해상도로 설정이 안되네요...
정확한 답변좀 부탁드립니다...
