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?
I wonder if it’s a BIOS / Firmware bug. There seems to be some persistent issues with sleep/suspend, battery consumption, lid open / closed state, fan spin when sleep (workaround for the ‘heat’ issue)… And it looks like Framework is still having two Firmware Engineer roles waiting to be filled.
Forgot to mention running Windows 10.
If it is BIOS/Firmware related hopefully a fix is out soon…
I recommend connecting via a USB-C Hub adapter, that’s what fixed my input lag from my monitor, also allowing me a much higher refresh rate. As long as you have a USB-C port on your laptop, it allows you to have much higher connectivity speeds and thus allows you to plug a DisplayPort cable to your laptop from your monitor. I went wrong by using HDMI which was too slow. This is the USB-C Hub that I bought from Amazon https://amzn.to/43VkmjL
Good value for money and I highly recommend using it starting off. Now I’m running 165hz on my Samsung G5 Ultrawide monitor. Hope this helped!
