Question External display getting low refresh rate, despite proper cables

My display is 144hz and works properly on my desktop over HDMI. When I use the same cord and plug into my laptop, the refresh rate caps at 100hz @1080, and 60hz @1440.

I purchased a USB C to HDMI 2.0 cable and plugged it in to the laptop, same results.

My display does not have displayport, but the point is HDMI works fine on the desktop, and the CPU clearly supports the bandwidth for this resolution over HDMI:

Drivers are current. Windows 10.

What am I missing?
