And I've read it somewhere that Asus G751 is only equipped with HDMI 1.4 and I think it's either Cnet or similar review site. Linus has mentioned Asus G751 comes with HDMI 1.4 on one of his review video. https://www.youtube.com/watch?v=6h0y70hneqw
And someone on this forum mentioned that somehow he was able to overcome by just using HDMI 2.0 cable but without any solid evidence. I understand that HDMI 1.4 is capable only at 24hz and HDMI 2.0 at 60hz. Since I do not have any tool to test, I'm not able to research that myself unfortunately.
So I would really appreciate if someone who still has/use G751 with GTX970m and 4K monitor/TV can confirm if 4K is capable on this beast.
My plan is to use G751 as a source of 4K movie via HDMI 2.0 to 4K TV.
