Best answer: Though the 27-inch ViewSonic VP2768-4K is a great monitor and can be used for gaming, you should invest in a more appropriate monitor that doesn't have a main focus on photography and design. This can save you money depending on which model you choose, and you'll be able to get something with either FreeSync or G-Sync tech, a higher refresh rate, and a lower response time, which are all specs that gamers should seek out.FreeSync 4K monitor: LG 27UD68-W ($399 at Amazon)G-Sync 4K monitor: AOC Agon AG271UG ($800 at Amazon)Professional 4K monitor: ViewSonic VP2768-4K ($573 at Amazon)
