I have a MSI 290 and got a new monitor the EX3501R. It is 1440 ultrawide. The problem is it set to 60 hz but capable of 100. I am using the DP cable that came with the monitor. Freesync is turned on. Settings Say link setting is 5.4 gbps x4. Monitor and graphics drivers are up to date. I'm stumped, at getting it higher, anyone have an ideas?
