KabelDirekt 7.5meter (2,3,5m also) plus a choice of Mini to HDMI or Micro to HDMI leads of a choice of lengths with the Apple connector Mini Displayport adaptor.This is apparently the same physical size as the new thunderbolt connector so it may be backwards compatible. The Mini displayport allows you to connect your mid 2010 iMac/macbook pro etc. to a TV.The mini/micro connector is useful for cameras, phones to TV, scroll down the page to select the mini/micro cable first and get 3 cables for £2.89 or less for the shorter lengths. It is part of the add on programme so you will need to spend £10 but if you are in the market for some cables you can get 8 cables and 4 adaptors for just over £10.The white HDMI cables also appear to be the newest spec. 4k.Very positive reviews and I'm very pleased with the quality of the ones I've ordered.
Scroll down to 'Special Offers and Product Promotions' to choose your extra FREE cable - these are all blue/black cables, with micro or mini HDMI at one end - you have to buy them together from that page or it won't work. You should get the black/blue cable for free when you go to the final checkout page. You might have to mix different cable lengths, I tried buying several of the same and it didn't work (in the same order, it works if you put the same order through several times, so if you have Prime delivery this should work).
