I was wondering if Daniel could shed some light on this
http://www.tftcentral.co.uk/news_archive/39.htm#panels_lgdisplay
"In the 34" ultrawide space there is already a 3440 x 1440 resolution @ 100Hz IPS LM340UW4 panel available and used in some displays. There are plans to produce the LM340UW5 from May 2018 which will offer the same resolution but a boosted 144Hz refresh rate. This will be combined with NVIDIA G-sync and also VESA HDR 400 support. This will then offer a 1900R curvature, 400 cd/m2 brightness (550 cd/m2 peak), 1000:1 contrast ratio and 98% DCI-P3 coverage."
If this is true, I wonder if the 34gk950g will actually be using the UW5 screen instead, meaning it will be 144hz native, and hdr 400. Now this would be the ultimate monitor giving the QC is good.
