My new Samsung P2770H monitor hums when you set its brightness to less than 100% (increasing in volume gradually down to about 90% brightness, then staying about the same for lower values of brightness). In a quiet room, this hum is annoying, noticeably louder than my laptop's disk & fan - annoying enough that I am only using it with brightness at 100%, which is brighter than I'd otherwise like.
Is this a problem with this model in general, or should I return it to the shop for maintenance or replacement?
Help, my PC with Windows 10 won't shut down properly
Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
