For those looking to improve their work computing environments...
I picked up one of these 4K LG TVs to use as a monitor for under $700 on Amazon:
LG Electronics 40UB8000 40-Inch 4K Ultra HD 60Hz Smart LED TV
[Link: amazon.com]It's been a real productivity boost, providing an enormous workspace for every day computing and an excellent canvas for system designs at ARCH D scale.
