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

I bought it to keep on my sailboat and use a FireTV Stick with it to watch TV when I'm outside. It is also used on the boat as a large monitor for my MacBook Pro. This works very well for both purposes. The reason for the 3 stars is that the refresh rate is surprisingly slow compared to the "mouse pointer" on my MacBook. When I move my mouse or trackpad, I almost have to wait for the cursor to get where I'm pointing. Maybe it's a bit of an exaggeration, but these days we're prone to things like this and it seems to be slow. I looked at the settings to make sure it's at 60Hz, no change.
