I have been switching from PC to MAC for the last couple years. One of the last bones was my desktop computer which had a SAMSUNG 29'' HD monitor.
Last friday I bought a MAC MINI and connected it to the Samsung thru HDMI. I had almost a breakdown when I realized the blurry text from the OS X against the crisp and bright text from the Windows machine. I started to investigate without any luck until I came across this post. Thank you MissKillALot, you save my day! Finally now I have a monitor working like it should, and no more PCs at home!!!
P.S. No wonder people keep ditching Samsung equipment: For the HDMI - DVI PC port to work properly you have to "RENAME" the port from HDMI to DVI PC. Rename? Who thinks that by "renaming" some port it will actually change its properties? Is this on purpose to annoy the user?
