Question My 165hz monitor displays 60hz, what am I doing wrong?

[pcbuilder777]

I bought a 1080p monitor with a 165hz refresh rate (KTC H24T09P). When I go to advanced display settings, the highest I see is 60hz. The monitor is connected with an HDMI cable. This is what I see:

Any ideas on how to get the advertised 165hz? I feel like this monitor isn't any better that the one that I had!

HD6950 is almost 14 years old. The very old HD6950 can't do 1080p 165Hz on HDMI. Maybe Displayport will do.

Thanks, I'll be building a new pc soon. Should I stick with the HDMI cable or buy a displayport? I'll be using 1 monitor and gaming.

Stick with HDMI for now if you build new soon. HD 6950 uses mini DP I guess which is unusable for recent GPUs. Buying a mini DP cable is a waste of money.

Have you looked in the amd gpu/display software, or just windows?

I don't know what to do in the amd catalyst control center

In Desktop Management, it shows what monitors are connected...Can you take a screenshot of the page and upload it using imgur.com ?

If I go to "desktop properties" I am able to select 75 hz (It says it's not supported and will cause a change in desktop resolution). I'm going to be building a PC with a RX 7700 XT maybe it'll work then?

Ok, try looking into each category and each drop down option in each group to look for other display properties and options, for video card as well. It may have further hz options available or to enable.

If all else fails at least now you can get 75hz 👍

Displayport to mini Displayport cable is not that expensive ~$10.

I didn't see any hz options. I saw the following things: Gamma, brightness, contrast, rotation, preferred color depth, preferred scaling mode, enable GPU up-scaling, enable ITC processing, hue, saturation, scaling options (underscan and overscan), hdtv modes supported by this display, predefined and custom hdtv formats, pixel format, basic video color, advanced video color, video quality (edge-enhancement, de-noise, mosquito noise reduction, de-blocking, enable dynamic contrast), deinterlacing, anti-aliasing, texture filtering, frame rate control, tessellation

I'm buying a RX 7700 XT which has Standard Display Connectors
1 x HDMI 2.1，3 x DisplayPort 2.1 (only 2x simultaneous DP2.1 connections can be supported). I was just hoping it would show a higher refresh rate on my old PC so I could test it but I guess I can't make the most of the monitor on my old PC's graphics card.

HD 6950 should support 1080p 165 Hz over DisplayPort, you just need a mDP cable or adapter to test it.

Catalyst Control Panel doesn't have refresh rate controls, it was just done through Windows settings. Anyway, AMD drivers in this era limited to 165 Mpx/s (1080p 60 Hz) over HDMI, although there is a 3rd party utility to patch this limit out of the driver.

When I buy the new graphics card would I get a better refresh rate with a displayport? Which one would I need to buy? The graphics card and monitor displayports are different numbers. Thanks

You will be able to get the full refresh rate of the monitor. Even your current graphics card should be able to do that with a DP cable.
