The Hisense 50" EC591U has caught my eye for £429. I know I don't need 4K but for the price I think it's worth considering. Whats the deal with Hisense? Genuine contender to the BIG 4 or not quite there yet? I read the AVF review of the K321 and it wasn't exactly glowing. Gamma in particular was cited as being wildly askew. However, the general feedback from owners seems to be mostly positive. Would anyone care to elaborate? Any thoughts would be much appreciated! Does anyone know if the EC5 has a native 100Hz refresh? What is the general AVF consensus about Hisense? TIA.
