So set up the 38" LG and the Apple logo isn't stretched (CSM is disabled). Neither is Clover menu (but background won't fill in though even if set to 3840x1600 in config.plist). @kgp
BIOS screen is not stretched either.
But yes definitely the Apple logo doesn't look "retina" to me like it did with a 2560x1440 display...
Otherwise, it's great and I see HiDPI options in Display settings...but no 75Hz setting. No issues with DisplayPort. I have "DisplayPort 1.2" enabled in the menu.
Waiting on the 2nd one....but I think one of these monitors and a 27" 4k LG monitor would suffice.
Nice to know..

Although.. note that, if I properly remember, you use a slightly different model when compared with mine (38UC99-W)..
Also I was never referring to the Apple Logo during boot, as I usually boot my MacOS System in verbose mode (thus I rather referred to the stretched boot messages). But in fact I was also referring to my stretched iMac Pro ASUS Splash Screen logo right before system boot, which I manually implemented in the BIOS firmware.
If boot messages etc. are stretched or not mainly depends on the following monitor setting:
/Input/Aspect Ratio/:
Full Wide (all stretched),
Original (not stretched), but ASUS Splash Screen, verbose boot messages and BIOS screen are not full screen but restricted to the actual size of the automatically applied boot screen resolution, which is definitely non 3840x1600.
Enabling "DisplayPort 1.2 Compatibitly" in the onscreen monitor settings, would allow you to drive your display at 75 Hz via Display port under macOS without any further restrictions. The "Free Sync" option must be disabled though, as otherwise your display would not be recognised at system boot.
