Review on Enhance your viewing experience with HP V28 4K Monitor - DisplayPort, Tilt Adjustment, Ultrawide Screen, Blue Light Filter, 8WH57AA#ABA by William Gadit

I've tried an HP laptop and a Lenovo laptop and they both have black borders at the top and bottom. The maximum resolution is only 2560x1600. I also tried it on a Macbook, there is no black border, but the max resolution is still only 2560x1600. Do not buy this if you are unsure if you can get 4k resolution. I'm back and I wasted my time!
