I've got HD 6570 with 1024 Mb memory and two monitors working as one worktable. Monitors can support 1920x1080 (3840x1080 worktable), but when I set in Catalyst Control Center this mode, it asks for reboot and then it falls down to 1680x1050 for both this monitors (3360x1050 worktable) and mouse doesn't work. Then I've got to run "aticonfig --initial" command and set displays to 1680x1050 (3360x1050 worktable) - this configuration works fine.
Is anybody here who knows what's a problem?
Catalist driver 12.4.
