Macbook pro with external display maxing out to only 1080p at times.

I have a Macbook pro 13 inch 2020 model. I will connect it to the the external display (QUAD HD - HP monitor) always. Many times, when I am connecting the mac to the display, the resolution in the monitor is maxed out to 1080p and its slightly dizzy too. I have to plug and unplug multiple times and change ports to make it work at 1440p. This is is annoying and horrible.

The thing is that, I also use the same monitor with the same HDMI cable with my dell CPU. It never gives a problem and works at 1440p always.

Model: Macbook pro 13 inch 2020 2TBT.

Adapter: USB C to digital AV adapter.

OS: Latest Catalina version.

MacBook Pro 13″, macOS 10.15

I tried doing the safe mode thing and SMC reset. Maybe if it happens again, I will try the two above. This thing is scary because, this is a replacement Macbook pro 2020 already for my 2019 one.
