    Welcome to the wonderful world of copy protection


    Your display may not be on the "approved" list, or was removed from it.


    Apple's newer Mac lines includes a form of digital copy protection that will prevent protected media, such as DRM-infused iTunes movies, from playing back on devices that aren't compliant with the new priority protection measures.


    The Intel-developed technology is called High-bandwidth Digital Content Protection (HDCP) and aims to prevent copying of digital audio and video content as it travels across a variety of display connectors, even if such copying is not in violation of fair use laws.


    Among the connectors supported by the technology are the Mini DisplayPort found on Apple's latest MacBook, MacBook Pro, and MacBook Air, in addition to others such as Digital Visual Interface (DVI), High-Definition Multimedia Interface (HDMI), Gigabit Video Interface (GVIF), and Unified Display Interface (UDI).


    Apple has apparently acquired a license for the technology and is now using it across its lines to to prevent transmission of purchased iTunes content (and some DVDs) to devices that don't include support for HDCP.


    The problem can often be solved by using an HDMI to Component Video adapter.  Many believe that Component Video will give you a better picture than HDMI without any of the hassles of HDCP.

    Thanks Ziatron.


    This tv is an early 2011 model from samsung. Is there any way to verify if my tv is in the "approved list"?


    Is anyone facing the same issue?Has anyone tried using the composite adapter?

    The same issue here.

    I have a LG LCD TV(32LD450), the new i5 2.5 mini.

    Via the HDMI connection, image quality is awful, not acceptable.

    Most of people using Samsung, LG TVs hooked up to the new minis have no issue.

    Maybe only yours & mine are not on the "approved" list, or were removed from it?

    It's ridiculous!

    I have been using this TV with the late 09 mac mini with no problems at all.

    yes, this is really very disappointing .... can any apple representative confirm the "list"? and is there anything we can do abt ?



    have you tried using the composite adapter suggested by ziatron?

  • lwsumm Level 1 Level 1 (10 points)

    It's component, not composite. Although the component supports up to 1080i, it's analogue, so inferior to HDMI which is digital.

    Why not try the thunderbolt port? Connect a mini-dp to dvi adapter to the thunderbolt port, and connect the TV with a HDMI-DVI cable.

    Your problem is your hdmi cable I think. Not all hdmi cables are equal. Buy a monster or audioquest hdmi cable from amazon and you will surely see a difference!

    Hmm, thx Kain , not sure if Hdmi cable is the root cause as I am able to output my ps3 in 1080p using the same cable and tv.

  • Commodore Kain Level 1 Level 1 (0 points)

    Well if you are willing to experiment with $30 on Amazon to buy a quality hdmi cable it would be worth it to see if somehow that is the issue. Best of luck to you.

    I managed to solve in my Samsung LED TV 40 -

    I clicked on the Source button on my TV remote control. Then click on Tools on the HDMI port on which the mac mini is connected.

    Then select Edit Name. not type the name, chosen from the list option DVI PC and it was amazing, it worked fine for me, so I have to improve the contrast now.

    wow! it works ! thank you so much!!

    This also worked for my Samsung (LN40B550) after making the change described above and then rebooting my mini (mid-2011)
