Question M27U Locked at 60hz with DP and 120hz with HDMI 2.1?

[Temp1]

I just bought this monitor and after setting it up and doing some testing with different cords have found that:
1. Both display ports (one that came with the monitor, and one that came with my old monitor I had used for over 6 years with NO issues, I had ran it at 165@1080 and 260@1080 if i OCd it) don't get me above 60. Nvidia panel doesn't work either.
2. The HDMI 2.1 gets me to 120, but still not the 160 that is not only advertised, but shown in the physical monitor settings.

I have a 1050ti and R5 2600, I am upgrading very very soon and this monitor was the first thing that had arrived. I don't plan on gaming at 4k with this current set up, but just confused on how it is locked. Control panel doesn't let me save a custom resolution even though it says it had worked fine. I've made them before for higher refresh rates on my old monitor and using the same steps it appeared to work but it wouldn't actually save anything. Could it be a GPU bandwidth issue? That's what I've seen a lot of other people say regarding similar issues.

Welcome to the forums, newcomer!

You might want to use DDU to remove all GPU drivers(Intel, AMD and Nvidia) in Safe Mode, then manually install the latest GPU driver sourced from Nvidia's support site in an elevated command.

The 1050 Ti has HDMI 2.0 which is enough to run 4K/60 and DP 1.4a which is enough to run 4K/120 (without HDR) so if you're running it natively those are the hard limits for your current hardware. If you want to run higher refresh rates you need to lower the resolution.

So 4k 120 is the limit for this GPU? That's what I had thought before but after asking around in some discord servers and other threads people were acting like this was a much more complicated issue. If I upgrade my GPU I wont have any more issues regarding this right?

Correct.

RTX 2000+ supports DSC (visually lossless compression) over DP and RTX 3000+ support HDMI 2.1.
RX 5000+ supports DSC over DP and RX 6000+ supports HDMI 2.1.
