A:Answer A few differences, mainly to the good. First, the overall brightness capacity is increased over the 2016 models by about 25%. Also, the ABL, (automatic brightness limiter), is far less aggressive on the 2017 model, and if you set the 'Oled Light" setting below 35 it is virtually a non factor at all. There are no 'Component In' inputs on the 2017 C7 or E7 though I believe there were on their 2016 counterparts. Go to the RTings.com website and pull up the LG C7 Oled review page. There's great info there on the TV, (C7, E7), and in-depth guidance re settings, etc. I got the E7 because I preferred the front firing speakers, (hearing issues), but both the E7 and C7 have the same screen and software, etc. This is one fantastic television, now connected to a 4K 11.2 channel Denon AVR and an Oppo 4K Blu Ray player.
