Just hooked up an LG 29" Ultrawide 29WP500 to my DIY laptop.
Resolution is 2560 x 1080, with a max refresh rate of 75. 5ms response time with FreeSync.
I have it connected via an HDMI expansion card now as I thought my external hub was the issue. Still see a good amount of lag while the lid is closed. I changed power settings to do “nothing” while lid is closed.
It seems for a few minutes it’s fine without lag until I go Idle and lag will come back up. Any suggestions?
