Yikes, that is scary, Laura.
I am at my sister’s house and managed to leave behind the cable I needed for my second screen. I tried several of hers and they did not work, so I’m not sure if it’s a cable issue or the screen has somehow died. But I can’t work just from my laptop I’ll go nuts, so we hauled out/unpacked my brother in laws GIANT MONITOR which is a 34” wide screen. I think I can see pivot tables into the FUTURE on this thing it’s so big.
