Lightroom preferences->Performance tab, uncheck the GPU option. It might be necessary for you to restart Lightroom.
Many thanks Jim. Based on other answers (which I found after I had posted my q) I also disabled the display adapter in device manager, then did what you suggested in LR, then re-enabled the display adapter. It seems to have worked. Really appreciate your reply.
for all the noobs AKA me. ONCE IN LIGHtROOM, click edit at the top of the menu, edit> preferences>Performance tab, uncheck the GPU option. YOU MUST CLICK "OK" [It might be necessary for you to restart Lightroom.]
took me 5 minutes to figure out where the preferences were, as i only got this windows 10 laptop a few hours ago (switched from mac)...if anyone else was lost, thanks to JimHess
