Yes the review was very positive.
I imagine most people want to hear about the 1 MS quoted response time. Unfortunately LTT didn't specify figures for pixel response but they did compare pixel response using blur busters guide with a camera on a slider. All monitors at 120 Hz they compared to the LG 34GK950G and Asus PG258Q and in the results it looked better than both because there was more ghosting on the 34GK950G and the PG258Q had some overshoot. I am not sure how fair this comparison is though as the PG258Q is a 240 Hz display. I don't know what OD settings they were using on the other monitors but on the 27GL850 they were using the fast setting because fastest introduced ridiculous levels of overshoot. It looks like the fastest mode was just to get the 1 MS figure on the box but fast setting seems to work great. It will be interesting to see what the response times are on the fast setting once of the bigger monitor reviewers take a look.
