I'm looking to replace my dual 24" 1920x1080 monitors with a single 38" monitor. These are the two models I'm trying to choose from: Dell U3818DW https://www.dell.com/en-us/shop/del...c/monitors-monitor-accessories#configurations LG 38WK95C-W https://www.lg.com/us/monitors/lg-38WK95C-W-ultrawide-monitor#tech-specs From some reviews I've seen, it looks like they both use the same LG panel. If that's true though, why is the LG able to be set to 75Hz, while it looks like the Dell can only be set to 60Hz? Also, LG lists the 38WK95C as being HDR10 while Dell does not list that for the U3818DW. Are these differences due to firmware? I tried to find these on display locally, but the only thing I could find was a LG 38UC99-W which looks to be the model being replaced by the 38WK95C. I was able to set the 38UC99 to 75Hz as well though LG's site says it does 60Hz / 75Hz with FreeSync. I've been happy overall with Dell monitors I've used in the past. Good warranty, sturdy builds. Haven't owned a LG before. My video card is a GTX 1080ti.
