I need my Mac Mini 2012 to be 7.5m (25 ft) away from Apple Cinema Display (Cinema NOT Thunderbolt version) on my desk. The Mac Mini's HDMI is already in use, so cannot use that. NOTE: I only need to extend the Mini DisplayPort connection here on the display, not the USB/MagSafe parts of the ACD's built-in cable. How can I achieve this (hopefully reasonably cost-effectively) given Apple's displays have built-in connection cables? _______ I wondered if I could do this... - 1st: Use a 4K mDP-to-HDMI (mDP MALE-HDMI FEMALE) adaptors, two of which Apple are selling (Moshi or Belkin): £30: http://store.apple.com/uk/product/HFQL2VC/A/moshi-mini-displayport-to-hdmi-adapter-4k £25: http://store.apple.com/uk/product/HGFB2ZM/A/belkin-4k-mini-displayport-to-hdmi-adapter - 2nd: Then use a 7.5m HDMI cable (MALE-MALE) of some kind (do I need a specific type that can handle above the normal 1080p of most HDMI cables, or will any of those "high speed" HDMI cables work?). HDMI cables are generally cheap and readily available from researching, but there seems to be several "Gbps" speed options an Amazon, without specifying which version of HDMI they do (eg. 1.4 vs the new 2.0)? - 3rd: Then use a HDMI-to-mDP (HDMI FEMALE-mDP FEMALE) adaptor as the built-in ACD mDP cable is male here remember, hence I need a female-female adaptor or cable. Are these available, and if so where? ______ The issue I have is, HDMI is currently supposed to only do upto HD 1080p, and not upto the ACD's 1440p, do you need a certain type of HDMI cable? Mini DisplayPort cables only tend to go up to 3m (10 ft) maximum, so the only other solution is to use a standard DisplayPort cable (I've seen so-called "active" 7.5m/10m ones available) in the middle instead with adaptors??? Again, I'd need a female-female one for that as well (DP FEMALE-mDP FEMALE)...?! Someone PLEASE HELP, there must be a way of doing this, I'm completely stuck?
