Question Monitor 144hz/165hz only showing 120hz

Hi all.

Monitor: Viewsonic XG270QG 1140p / 144hz-165hz
Display Port: 1.2
Connection: Displayport (Monitor) to Mini Displayport (Laptop).
Cable: Supports 4K @ 60Hz with ultra-high definition video and clear image content. Backwards compatible with 4K @ 30Hz, 2K @ 165Hz, 2K @ 144Hz, 2K @ 60Hz, 1080p and 720p
Graphics Card: Nvidia GeForce GTX 970M GPU with 6GB of VRAM and an Intel HD Graphics 4600 GPU

Unfortunately, when I goto > Display Settings > Advanced Display Settings > Select my Monitor> Display Adapter Properties > List All Modes, I only see refresh rates up to 120hz @ 1440p

Am I doing something wrong?

I've used the search function, have found numerous results relating to this topic, but none that have helped me at least rectify 144hz.

What could the issue be?
  1. Find another cable?
  2. The Graphics card?
Thank you in advance, I know theres many topics like this so appreciate it.

Have you tried setting OC mode in your graphics card settings?
Seems to me your GPU is putting a cap.
Try looking into the Nvidia Software, it's pretty good. You might find something there.
Hope it helps

Checked the display adapter settings this morning. Any idea?

That's normal. If it were 10 bit it would explain why you are limited to 120 Hz, but since it isn't, I'm not sure why you are being limited. Try setting a custom resolution using the instructions in section 6.3 here: https://forums.tomshardware.com/threads/how-to-connect-to-a-120-hz-display.3268285/
I tried setting a custom resolution this morning:

2560 x 1440 @ 144hz.

Says The custom resolution exceeds the maximum bandwith capacity.

Is this a cable issue? graphics card issue?

Is the monitor 144HZ native, or is it an OC function? Might have to check your monitor's OSD functions see if that's a setting. To answer your question directly, yes it could be that youre using an outdated HDMI or Display port cable,
but not likely. Dont think that the wiring has changed all that much, but I could be very wrong.

Previously, when I was waiting on my DP cable, I was using a HDMI cable. Native was 60hz.

With this DP cable connected, I go into the OSD function, it's set to Native 120hz with the option to OC to 165hz.

I personally feel that I MIGHT be using a cable that only runs up to 120hz. I don't even know.

According to Ivanky (the cable manufacturer I'm using), it's showing this:

High Refresh-Rate Gamer-friendly refresh-rate (2K@165Hz, 2K@144Hz) and high resolution up to 4K (3840x2160@60Hz) makes it an optimal choice for smoother, tear-free gaming experience.

That's why I bought it, because of the 2k 144/165hz option.

Could be the cable. If you have the 10 bucks to spare it's worth a go if you've tried everything else.

It's not a cable issue, as 2560×1440 @ 120 Hz is transmitted at the same speed as 2560×1440 @ 144 Hz and 165 Hz, if it were not able to handle this speed due to the cable then it would drop to 85 Hz.

The "exceeds maximum bandwidth capacity" means you're being limited by your Intel integrated GPU.

Yeah, I noticed that for desktops vs laptops the integrated GPU can be overridden by desktops. But for laptops it's unfortunately shared and "thats the way it goes".

Someone out there has been through this, and whoever you are, enter this chat now please lol

I'm actually not limited.

If not, update your GPU drivers. Maybe the Intel GPU don't support above 120hz?

GPU drivers are the latest, May 2020.
Intel drivers are January, 2020.

Intel GPU does support as in my post. You can see below the bandwidth is all the way to 2160 @ 60hz. I'm only needing 144hz at 1440p.

1440p 144 Hz takes more bandwidth than 2160p 60 Hz.

Exactly, 1440p144 is more bandwidth than 2160p60. 1440p165 is even more.
