Review on Sceptre U275W UPT 27-inch 4K DisplayPort Monitor - 3840x2160P, 70Hz, Frameless, Tilt Adjustment, Flicker-Free, Built-In Speakers by Shane Saric

DP does not connect after a month of use. yes, exactly a month later DP lost contact. And I can't even return it until the expiry date of the return policy. So please give other buyers a bad review. The color of the monitor is really nice, it costs over $500, but the quality is so low that it becomes a risky business in my opinion. Now I switch to the HDMI port which only has a 60Hz refresh, can't complain about that anymore. (DP can run at 70Hz). thanks
