Why is it that I can't find any reviews, youtube videos or really no mention of this exact monitor online? Only thing that ever pops up is the 38UC99 instead of this 34"

Asked by: Arjen
LGJoel: Thanks for answering. I had already seen that YouTube video. It's a slideshow of images and text I can find right here on this website. You can't really call that a review. Why are there no Youtubers who did any reviews on this? And a monitor that was released in April this year is also not 'recently'. I'm thinking of buying this but the lack of good / any reviews is stopping me right now.

75Hz work with video card Nvida GeForce GTX 970M 3GB? or only 60Hz. Windows show me only 60Hz. I connected with Displayport mini to Displayport 1.2

Asked by: Makson
We do appreciate your interest in this monitor. I do apologize but I do not fully understand the question. The compatibility of the video card with the monitor would depend on the resolution settings, the refresh rate of the video card, and the OS being used. For better assistance, please contact our Customer Interactive Center at 800-243-0000.
