I have a Samsung SyncMaster s20b350 that has worked perfectly when connected to my macbook up until today. I have ruled out the mini displayport to hdmi adapter as being faulty because it still doesn't work when connected with just hdmi to a windows computer. It's not the hdmi cable because it works with my xbox. The weird thing is it works when connected with an hdmi to micro usb port to a windows 8 tablet, but not through hdmi to a windows 8 pc. I have reset the monitor to factory setting and it still doesn't work. The windows 8 pc doesn't detect the monitor but the macbook does, but neither display a picture. Any ideas?
Edit: It seems that my monitor is not capable of switching to hdmi both while not connected to anything or connected to my macbook. When I try to switch the source to hdmi is quickly cycles back to analog in about half a second.
