Review on AOC U2790VQ – 4K Frameless DisplayPort Monitor with Tilt Adjustment, Wall Mount, Blue Light Filter by Dan Martin

This is a great budget 4K monitor. Mine arrived well packaged with no dead pixels, lines or any issues. A side note: there's a slight vignetting (I learned the term from another monitor review) around the edges. So if you display a light color in full screen, it will appear faint/shadowy towards the edges of the page. I almost never work full screen with light color, so I got over that quickly. I only noticed this because the very first window I maximized turned out to be a plain text editor with a white background. I could rule out this monitor when working with full screen graphics, but it doesn't, so I have no motivation to return it for an issue that doesn't really affect me.
