$200 USD - New Dell S2817Q 28" Ultra HD 4K Backlit Monitor
I bought two when it's $220 last time. Put dual screen and works great. Same seller Buydig. Brand new in Dell package. Comes with HDMI cable and mini DP cable. No tax to new york state. I drive to border and pickup it, only 13% HST.
Only thing I don't like is: it doesn't have portrait mode.. For this price , I can live on it.
