I have my Xbox mirrored to three displays: - 65" Samsung 4k: 4k up scaling looks great but is horrible for gaming. I have to turn this set to PC mode for it to be pretty good but still has a little lag -50" 42" Insignia LCD/LED: actually works very well for a low end set - 27" Asus IPS Monitor: my favorite by far. Didn't by it for gaming but the colors are great and amazing response time TLDR - 4k is pretty but caused lag. Use a monitor
