First off, are you refering to syncing photo settings in develop module?

[#4]

Second up, please share/post your System Information as Lightroom Classic (LRC) reports it. In LRC click on Help, then System Info, then Copy. Paste into a reply. Interested in info from first line down to and including plug-in info. Info after plug-in of no value (at least not to non techs)

The Nikon Teather comes by default on all copy's of LR.

NVIDIA GeForce GTX 970 (26.21.14.3603)

That would be v436.03 current driver would be v442.19.

You will want to use the NVIDIA GeForce Experiance utility to update the GPU driver, when you do, select Custom as to install a clean copy (removes all old stuff)

Dual Displayys at 1920x1080, so not 4K and beyond. If you have use GPU enabled in /preferences/performance/ that might be of no value, and might hurt. If on, try with it off.
