I have Dell Optiplex 7090 Ultra with I5-1145G7 connected with 34" Viewsonic VP3481A by Type-C. The monitor supports 3440x1440x100Hz mode. The version of video driver is 126.96.36.19955. Before I've updated it by lastest version I was able to set 100Hz refresh mode, but after - 30Hz and 60Hz only available. That's happen ?
