I recently bought the ViewSonic VX2758-2KP-MHD 1440p 144hz monitor and have been trying to drive 144hz. In windows I can only select 60hz or 120 hz. I'm using a displayport to displayport cable from the monitor to an MSI Mech 5700XT. The monitor and GPU drivers are all updated and I have FreeSync enabled. How can I change the display to 144hz?
Edit: Windows shows me an option for 144hz after scaling down to 1080p but disappears when at 1440p.
Thanks but I've tried that hence why I mention only the 60 or 120hz options are available.
Are you using display port?
mines working perfect using display port

I should of mentioned that it has to be displayport 1.2, my bad.
The GPU port is displayport 1.4 and I'm assuming the monitor's is 1.2 and above. The option for 144hz comes up and works when I scale down to 1080p but disappears again after setting it to 1440p.
@Kandkodos: No the cable itself has to support displayport 1.2 to be able to run 1440p at 144hz that's why at 1080p you can run 144hz.

This will help you, my guess is your cable is 1.1
@Axelstrife: From what I've read there's no difference between cables.

Despite what you may read, there is no such thing as a DisplayPort 1.1 cable and DisplayPort 1.2 cable. A standard DisplayPort cable, including the so-call DisplayPort 1.1 cables, will work for any DisplayPort configuration including the new capabilities enabled by DisplayPort 1.2, including 4K and multi-stream capabilities. All standard DisplayPort cables support RBR, HBR (High Bit Rate), and HBR2 (High Bit Rate 2), which can support 4K at 60Hz, or up to four 1080p displays using multi-stream.
Windows shows me an option for 144hz after scaling down to 1080p but disappears when at 1440p.
Sounds like a cable bandwidth issue. Have you tried replacing cable?
Probably wont work but you could also try
downloading GPU drivers and DDU,
reboot to safe mode,
uninstall display drivers using DDU,
reboot to safe mode without booting to normal windows first,
install driver again.
I also have the 5700xt mech oc but haven't run into this problem thus far. Have you tried looking at the AMD Adrenalin Control Panel to see if there are any relevant options or settings there?
Also it could be that windows is set to 10 bit colour which is limited to 120hz on DP from my knowledge. Try dropping down to 8 bit to see if that helps.
Can confirm it's on 8-bit depth in windows and in the adrenalin software. Doesn't seem like a refresh rate option in the adrenalin panel. What cable did you get?
have you had any luck man?
and sorry, I used the DP cable that came with my monitor (MSI Optix MAG322CQRV)
Hey there, I switched to a new cable today and it works at 144hz now! Although display port says there's no difference between cables I think they mean for display port ceritifed cables. My other one was a cheapo from eBay.
@Kandkodos: Sorry mate, late comment here.
The necessary cable doesn't come with the monitor to support 144 then? Where did you buy the new cable if you don't mind sharing?
@Rocket6: Hi, yeah it didn't come with a DisplayPort cable which is what my GPU can only take. I bought one off eBay - got a cheap one on eBay beforehand but it didn't support the 144hz rate so had to research which brand was actually capable of it.
