Will hdmi run 1440p 144mhz?

markfresh · 19 Jul 2019

Hi i have a vega 56 , i cant get 3 monitors to work on either 3 display port, or 1 DP and 2 HDMI , i can only get 1 DP and 1 hdmi to work at the same time.
I just rang the store i bought it off and they said to try HDMI on my 1440 p and DP on my 2 1080 p monitors.
Does HDMI support 144 mhz and also i don't think HDMI supports free sync.
So i have a GPU with 3 x DP and 3 x HDMI and cant even get 3 monitors to work.
Any help
Thanks Mark

Edit : i can get all 3 to light up but they dont show up in display settings and cant detect them , and windows spreads over the 3 monitors on a weird way eg , the right hand side of the taskbar moves from main display to another monitor with a white screen, and amd software detects them but when i click on arrange displays it just takes me to the windows settings page.

Q1 Starting HDMI 2.x cables its a yes , they run in network like protocol so they deliver what is thrown at them .
Q2 Vega 56 is known to have issues with multiple displays , however i believe your problem can be solved in display window you are directed to if you choose a 60 mhz monitor of the bunch and then scroll down and make it primary display . I cant seem to figure the logic behind it but it kind of solves it , oh and choose to extend the display not to stretch it .

I managed after another clean install ( i used AMD's clean uninstall instead of DDU) and it works , all 3 monitors all display port :)
