While Apple's is an all-in-one, those from Dell and HP are standalone monitors with a resolution of 5120 x 2880. HP also introduced a few other monitors at CES, including two new 4K displays. Here's what's new that you might find relevant:
HP Z27q

Though Dell's 27" 5K monitor might have a few more features than the HP, it's also about $1,000 more expensive. This makes the HP a much more realistic possibility for more people, though you'll need the GPU power to make it work as 5K requires two DisplayPort cables. One interesting feature of these displays is the ability to accept inputs from two different sources at the same, and do a picture by picture (in addition to picture in picture). When you've got enough pixels, those things start to become possible.
I'm sure we're going to see plenty more 4K and 5K displays in the near future (maybe even this week), so stay tuned.
