So a lot of affordable IPS high refresh rate monitors with 1ms response time are coming out on the market with decent reputation on the brands but not comparable to the Big brands. The only minor concern is that these monitors doesnt have any Nvidia GSYNC and AMD Freesync. Should i stay away from them? Example names of these brands are Migen, SANC, ViewPlus, Nvision, and many more. What big of a difference does the NVIDIA GSYNC and AMD Freesync provides?
