You need a new video card. I got the PNY GTX1050 from BestBuy for $119.99 (Amazon price match...Thanks Jeff Bezos). I don't do gaming, but this card was a noticeable win-10 (1703-pro) improvement from my old HD-7950 for non gaming windows use. I love the LG monitor and will buy another one next time they go on sale for $399. Note: The GTX1050 will run two 4k monitor simultaneously. I learned the hard way to stay away from AMD video cards. The windows drivers a buggy, and AMD quickly drops support for Linux on older cards.
