Question lg 34wl500-b wrong resolution after W10 update

Hi. Microsoft just forced me to upgrade to W10 Build 19041 and after the upgrade the resolution on my LG ultrawide 34wl500-b is screwed up. W10 seems to think it's an ordinary width monitor and is stretching the display horizontally. I can't seem to find any setting to fix it. Max resolution on Display Settings is 1920x1080, no 2560 x 1080 like before the update. Same for the options on the Nvidia control panel (for GTX 1050 Ti). I double checked and it has the latest LG HDR WFGD drivers. How to fix?

Update may have screwed up the Nvidia driver for the GTX 1050 Ti, so try re-installing it.

You had me all excited because I checked and the installed driver was version 442.19 whereas the latest is 456.55. Alas, installed the new one and it's the same situation. Max resolution listed is still 1920x1080 .

Oddly, NVIDIA Settings > system information give the above updated driver version, but Windows device manager says the driver version is 27.21.14.5655, which is not even the same format as the NVIDIA numbers. Maybe this is the problem?
