I just got a new ultrawide monitor and it supports 75hz but I can only get 50hz out of it, and it won't let me go any higher. How can I fix this?

So as the title says, I can't make my monitor 3440x1440 go up to 75hz for some reason. I know my computer can handle it on the current HDMI cable that I have because I was able to set it to 75hz on my previous monitor, granted it was only 1080p though and this monitor is a 1440p, and wondering if that may be the issue, but I don't see why it would be. So I need help in trying to fix this. Thank you.

Like I said, I was able to get 75hz from my previous monitor. Does it being ultrawide make a difference? And I am not sure what the version of the HDMI cable is but I have an Nvidia GTX1650

yep. A whole lot more pixel is pushed compared to typical 16:9 1440 (2560x1440), and if you do your own math, thats about several million pixels more. Youll need HDMI 2.0 or higher on both device to push above 60Hz.

How can I know if my HDMI cable is 2.0 or not?

Pretty much spec sheets and technical diagrams. There are no standardized markings for differing versions AFAIK.

Okay thanks for the info. I just bought a 4k 2.0 HDMI cable on Amazon just now. Hopefully this works.

Before you jump the gun:

Check nvidia control panel for the PC tab in resolution pick in change resolution option. TV is usually very low refresh rate.

Yes but if I try to create a new resolution, the only option it gives me is to test it, then it goes black for a few seconds, then turns back on and nothing...

What is your monitor? Some monitors may have both hdmi 1.4 and 2.0 and there's a chance you connected it wrong

Yeah there's 1 1.4 and 1 2.0 port. Find the 2.0 port in the manual.

Next time tell what kind of monitor. I usually only see 1-2 HDMI port tops in an ultrawides, more common with 1.

I didn't even know that they were different. I just thought that they both were the same so I can connect 2 different devices into them. But thanks for the tip. I will definitely do that next time. Thank you so much for your help.
