1. Consumer affordable monitors. You'll need a better GPU, and probably Display Port. I don't expect most consumers wanting 30" 4K display. They'll want 22-27" displays of 4K resolution, a la Retina. (PPI scaling) Everything is still the same size as people are used to (compared to 1080p), but everything is sharp as Retina.
2. 4K adoption of multimedia on the Internet. The more 4K videos that pop up on YouTube, the more people who are going to want to upgrade their hardware. This one isn't specific to PCs though, it could apply to mobile devices as well.
Go to YouTube and find a 4K video (the quality slider goes to "Original"). Now look at the comments. Many of the comments in 4K videos are people complaining how they can't watch the 4K video because of their crappy computer (and sometimes bandwidth).
