Hello all. I'm shopping around for a 4K resolution monitor for gaming. Problem is, I'm not entirley sure what I'm looking for. I know small response times are good, but how small is ok for 4K? 1ms or 2ms or higher? I know that higher refresh rates are good, so what's good and what's adequate? 144hz? 120hz? I know I want at least 27". And my budget is below $500. Is that achievable? FreeSync or GSync or none?
Is a 4K monitor even worth the effort? I currently have a 1920x1080 (1080p), so would I be better off just getting a 2560x1440?
I have a computer with 1080 and an i7-6700k to drive it.
I was hoping all you fine folks could give me some recommendations on technology, brands, and models.
EDIT: Changed title because the suggestions have talked me out of a 4K monitor.
