I have a mac mini running windows 8 these days, but it is the same issue on OS X regardless.

There are a variety of ports on the back of the mini, and currently I'm using a thunderbolt connection that uses a converter to VGA. I have the exact same two TV's, Samsung SyncMaster TA550. The the VGA resolution for my first screen is perfect, crisp. But the second monitor uses a hdmi cable as there is only one thunderbolt port. But this display doesn't fit the screen and is also a little blurry.

Both according to windows 8 are displaying the exact same resolution but different results.

Any ideas on a fix?

  • what is the resolution set as on the mac mini? – Logman Jan 1 '13 at 22:11

Thunderbolt can support 2560x1600, mac mini hdmi can only go upto 1920x1200.

The tv is scaling it down and distorting the aspect at the same time.

Fix:

  • You need to turn off the auto scaling on the tv source with hdmi (Doubtful)
  • Or lower the mac mini resolution to 1920x1200 (Probable)
  • Or Daisy chain the display (Maybe)

  • Both are running at 1920x1200, I'll try daisy chain though as I don't think it's the scaling of the tv. – samayres1992 Jan 2 '13 at 13:24

What worked for me was to dial down Underscan in the display preferences
