So I got a new Monitor (1440p 144hz) from lg for Christmas for my Mac (MacBook Pro 13" 2019 Intel Core i5 quad-core 1.4ghz) completely overkill, but after using it for I while I noticed that it won't let me use 1440p at 144hz only 1080p at 120hz or 1440p at 60hz I don't know what is causing the issue I think it's my intel mac, but I'm not sure. I tried to use boot camp, and it didn't change a thing. It's not the HDMI cable since I tested it with 2 one I got (something 8k I don't know) and the other one from the Xbox Series X (HDMI 2.1). Maybe it's my adapter (UGREEN 6in1 premium 4k 60hz adapter). I have also noticed when I change the resolution in the display settings it gets super buggy and I can't change the refresh rate and I can go up to 4k, which does not make any sense at all.

This could be due to a couple things, each requiring further research

 

1: Your intel integrated graphics cannot do 1440p 144hz possibly, 

or

2: The adapter cannot do 1440p 144hz.

 

one of these is the case.

But that's not the one that's most likely an older one ´

  • Crystal-clear 4K@60Hz Output: USB C hub highly supports 4K@60Hz resolution when connecting 4K monitor. You can directly stream your screens to HDTV, monitor, or projector easily for a cinema-like visual feast.(Note: The 4K@60Hz only available for laptops with DisplayPort 1.4 and above)

so for hdmi you will not get the results of 1440p 144hz, only 120hz.

So is there any adapter that would support 1440p 144hz that will hold for a while and has extra USB ports?

i do not know if the macbook can even support 1440p 144hz, it will take some looking into.

What does it mean with "only for laptops with DisplayPort 1.4 and above" I think there are like no laptops that even have a display port most of them have hdmi

I tried two 2.1 HDMI's, one from an Xbox Series X and one I got from my parents, and both worked with the Xbox, so I don't think it's because of the cable

It's DisplayPort that is carried over the USB-C connection. 

According to this the iGPU only supports DP1.2.

Does that mean there is no way on earth that I will get 1440p 144hz with this laptop or is it just the adapter that is stupid
