The BenQ EL2870U is a 27.9" 4K TN display that touts a 1ms gtg response time, supports HDMI 2.0a and DisplayPort 1.4, a FreeSync range of 40-60Hz and HDR 10 support.  The proof is in the testing however, which Kitguru conducted in their review.  The display suffers from an all too common flaw; it accepts HDR input but cannot properly display it so you should consider this a SDR display, more or less.  The colour calibration is not good enough for professional usage but would certainly function perfectly for gaming.  Check out the full details before considering a purchase.

"On paper, the BenQ EL2870U initially seems like the ideal entertainment and productivity monitor. It’s a stylish, flicker-free 28in 4K UHD display with a 1ms response time, AMD FreeSync and HDR 10 support, to list but a few of the highlights."
