I have a Samsung SyncMaster 900IFT that emits a high pitched whine for the first few mins of being turned on. I activated the standby feature through the powermanagement software in Windows 98, thinking that keeping the power running through it would be easier on it during the warmup process. However, once I move the mouse and the screen pops on, the whine is still there. Could this be a problem with the tube? I still have the option of returning the monitor as I purchased it about a week ago. Any help is greatly appreciated.
