The same problme like you.
If i set the screen to 1280 x 1024 the Keylock to crack it is not to see.
The proble i think is that Bethesta goes for Widescreen Monitors and only a few people like us use a standard 19"+
And another problem is that FO4 don't finde my Graphic card. Geforce GTX 750 (OC)
U can try the 16:10 stabdard with 1280 x 800. after that u end the configuration window. Go to documents/mygames/fallout4 find there the fallout4prefs.ini and open it. look there for bFull Screen=0 and set it to bFull Screen=1 so u hafe full screen and seeing the piclock. but this is temporary to fix it on the own.
So pls Bethesta fix FO4 that we standard useres with a 5:4 / 4:3 can take 1280x1024 in fullscreen to have more fun with this great game.
Oh and i forgot the Power Suit instruments are cut on the left and ride side so that we cant see how many Life and Amonition we have in the weapon.
