"The licensing company overseeing the HDMI specification has confirmed that some Mini DisplayPort-to-HDMI adapters are illegal, and could be recalled. However, the existing spec "contemplates" a cable connector that would be equivalent to the existing products on the market, which include a male DisplayPort connector and a female HDMI connector. That may make any legal issues largely moot, especially if the existing cables are formally brought under the spec's umbrella."

"These stores are trying to trick people into thinking they need an HDMI lead costing over £100 after buying a Full HD TV. This is simply not the case. You shouldn't be spending more than £4 on an HDMI cable," it said. "An HDMI cable is an HDMI cable," Kogan added. "It's a digital cable. You either get a picture or you don't. Don't get conned into buying a 'fancy' HDMI cable because it will make no difference!"
