Long-term isn't so bad - for example, long-term we'll be decked out with those fancy 5k monitors. I'm really trying to think of what to do late November when my computer arrives and I'm trying to plug it in to all my existing devices!Tell me about it. This is taking some real planning! Hopefully the transition happens quickly over the next few years.
But the fact that the current situation is transitional is what makes it difficult. How much do I want to spend to keep my ancient DVI monitor going until I get around to purchasing one of those LG monitors?
