I want to go for a 4K screen on my late 2013 Mac Pro (2x AMD FirePro D700). I currently have a 30inch Apple Cinema Display, and a second 1600x1200 DVI monitor, both probably consuming a lot of energy and desk space. It seems that nowadays there is a choice between a few very expensive 4K Monitors (via Thunderbolt), or I could go relatively cheap with 4K UHD LedTVs, which are connected via HDMI (and have tuners etc...). An example would be the http://www.newegg.com/Product/Product.aspx?Item=N82E16889005953: What is the catch here? Is the difference in quality really that big, between a Thunderbold or HDMI connection? Any Mac Pro users out there who have a 4K UHD TV as main 'monitor'? Pros and cons please!
