Added Acer 2416W as a problem model since it seems to require 57.1Hz.
Added Asus VK266H as known working.
Xantheous: No idea, but it shouldn't be a problem.
1) Refresh rates are not really an issue in Win7 anymore, thanks to
this.
2) We have 5 LG monitors in the list, all are "known working" :)
Turbine777: I can't think of any reason why the LED backlighting would be a no-go @57 Hz.
The official specs are of no help, but again this issue is not as "dead-ended" as it used to be, as it seems newer drivers allow refresh rates higher than 57 Hz, which all models should be able to output without problem.
It's up to you but I'd risk it with reasonable confidence... (That's not the model I'd use for multi-monitor because of the humongous frame, but hey.)
